Abstract:
Background: Seagrass grows and spreads in nearly all parts of the intertidal zone. Waai village has characteristic sloping coastal water and have different patterns of zonation of seagrass in the intertidal zone's third-impact on the presence of seagrass and the organisms in it. Methods: The study was conducted in coastal waters Waai village, in the middle of the intertidal zone (middle intertidal zone) and the lower intertidal zone (lower zone intertidal). The samples in this study are all kinds of gastropods found in each plot observation station of 100 plots. Gastropod species diversity using diversity index formula Shannon - Wiener referred to under Ludwig and Reynolds. Results: From the results of the study found 8 species of gastropods and has a diversity index that is currently in the middle intertidal zone, the average diversity index of 1.76, while in the lower intertidal zone, the average gastropod diversity index was 1.45. Conclusion: diversity index indicates the middle intertidal zone, the average diversity index of 1.76, while in the lower intertidal zone, the average index of diversity of gastropods is 1.45, this is caused by the different seagrass zonation patterns and habits of the people who frequently uses seagrass area for commercial purposes.

Abstract:
A floristic study of marine macrophytic algae and Cyanobacteria in the splash and intertidal zones at Luhuitou reef, Sanya Bay, Hainan Island, China, was conducted during the rainy and dry seasons of 2008−2012 utilizing 148 of the most common species. Macrophytic algal diversity increased from the splash zone to the low intertidal zone, while cyanobacterial diversity decreased. In the upper and middle intertidal zones, the dominant species (primarily highly productive ephemerals) changed frequently throughout each year. In the low intertidal zone, the dominant species (mainly annual fleshy, foliose and coriaceous forms) also changed. In the dry season, species numbers were 33% higher than in the rainy season. During the rainy season, Cyanobacteria dominated the splash zone, while green and red algae dominated in increasing numbers from the upper to the low intertidal zones. During the dry season the splash zone was devoid of all macrophytic algae, and only one species of Cyanobacteria survived. In the upper intertidal, Cyanobacteria and red algae prevailed, while in the mid and low zones, red and green algae were the most diverse. In spite of heavy pollution in Sanya Bay, there was no evidence of dramatic changes in species numbers or composition, and the marine flora was similar to that of unpolluted regions in the Indo-Pacific.

Abstract:
This paper provides data on diversity, zonation and seasonal fluctuations of decapod crustaceans at the northern Gulf of Oman coast, based on quantitative and qualitative samplings. A total of 75 species belonging to four infraorders, 27 families and 48 genera were identified. These species include 20 new records for the entire Gulf of Oman and 13 new records for its Iranian coast. The mid-intertidal zone showed a higher mean diversity and abundance than high- and low-intertidal zones. The mean diversity and abundance in the high-intertidal zone showed significant differences with the mid- and low-intertidal zones. The indices of species richness (Margalef), diversity (Shannon) and evenness (Pielou) showed significant differences among the intertidal zones. Most of the identified species (>60%) that had high values in their frequency of occurrence and relative abundance showed an overlapping vertical distribution, and were present in all three or just in two of the three defined zones. Other species were found only in one of the three zones (non-overlapping vertical distribution). The decapod community in the mid-intertidal zone showed a higher dissimilarity with the high-intertidal zone than with the low-intertidal. Both abundance and diversity were found to be lowest and highest during south-west and north-east monsoons, respectively. During south-west monsoon, the abundance of decapods declined dramatically, but species diversity and ecological indices did not show any statistically significant difference among the sampling periods.

Abstract:
AbstractLike other 'white' sticklebacks, those ncsting intertidally at Spry Bay, Nova Scotia, Canada, remove fertilized eggs from the nest, disperse them over the surrounding area, and provide no subsequent parental care. However the breeding substrate at Spry Bay is devoid of the filamentous algae which are the normal breeding substrate of the white stickleback and which elsewhere facilitate survival of abandoned embryos. Experiments show that embryos dispersed in the intertidal zone at Spry Bay survive surprisingly well despite the complete absence of parental care and the periodic absence of water. Intertidal embryos generally develop faster than embryos in the adjacent subtidal zone, but there are exceptions to this pattern. Intertidal males show site fidelity to their nests despite interrupted access to territory, and they show consistent preference for nesting in the intertidal zone in the field. In the laboratory, and in the absence of tidal flux and competition, males taken from the rocky intertidal zone generally prefer to breed on bare rock substrate even when filamentous algae are freely available. When white stickleback males from an adjacent population which breeds subtidally in filamentous algae are introduced into the experimental aquaria as competitors, they exclude the males that breed on bare rock. The surprisingly high survivorship of embryos in the rocky intertidal zone, the habitat selection of males for bare substrate, and their exclusion by males that breed subtidally on algae, all suggest that the highly unusual breeding behaviours of intertidal white males form an effective alternative breeding repertoire. Because breeding habitat selection has implications for mate selection, the possibility exists that sticklebacks with different breeding repertoires at Spry Bay may mate assortatively.

Abstract:
The intertidal zone is the area between the highest and lowest tides, which represents the transition from ocean conditions to land conditions. This study aimed to determine the diversity and distribution of mollusks that exist along the intertidal zone of Nglambor Beach, between August and November 2020. Observations of all molluscs were carried out at two random stations using 10 plots measuring 1 x 1 m 2 with 5 meters. A total of two classes of Mollusca (Gastropod and Bivalvia) belonging to twelve families and 19 species were found from upper to lower an intertidal zone. The upper intertidal zone was recorded to have the highest diversity and an evenness index (Shannon-Wiener diversity index: H ’= 2.524 and Pielou evenness index: J’ = 0.932) compared to the middle and lower zones. It can be concluding that the diversity index in the study location is categorized as medium and its evenness is high. Thais hippocastanum is the most dominant species found in the upper and middle zones, while Thais tissoti dominates in the lower zone. This research contributed to a preliminary checklist on molluscs, which will support a baseline study on the intertidal in future.

Full text
Abstract:
The population dynamics of rock barnacles, Semibalanus balanoides (L.), residing in low and high intertidal zones are affected by conspicuously different factors. The barnacle population in the high intertidal zone tends to show longterm stability due to a low incidence of both predation and interspecific competition. Wave exposure, desiccation and intraspecific competition are more important factors affecting abundance and size distribution in this zone (Menge, 1976). In the low intertidal zone, barnacle predation by the dogwhelk, Nucella lapillus (L.) is intense (Menge, 1976) and both the adults and larvae are smaller than in the high intertidal zone (Barnes, 1953). The growth form of S. balanoides is density dependent with taller, more columnar individuals predominating at high densities and short conical barnacles at low densities. Lower fecundity of conical individuals may be due to lower internal shell volume compared with columnar forms (Wethey, 1984). Fecundity increases both with increasing age and base length (Arnold, 1977) and is positively density dependent (Wethey, 1984).

Abstract:
A field study of cohesive sediment movements on a muddy intertidal zone (ITZ) at Portishead, Severn Estuary is presented. Five deployments of 1-3 days have been made to improve the understanding of temporal and spatial variations in suspended and bed sediments at a site which is found to be wave dominated. Pressure transducers, electro-magnetic current meters, optical turbidity meters and ultra-sonic bed level transducers are used to monitor the hydro/sediment dynamics in the bottom metre of the water column at two points on the ITZ. A one-dimensional (vertical) k-ϵ turbulence model has been modified to include bed sediment exchange and density stratification to enable further interpretation of field data. Modelling results show that the weak current on the ITZ would simply provide a mechanism for diffusing suspended sediment into the upper part of the flow, and does not enhance the wave boundary layer by its presence and cannot actively support suspended sediment. Hence near bed (wave generated) turbulence controls the vertical SSC distribution. A bed model based on bed sediment exchange via critical erosional and depositional shear stresses only predicts high near bed concentrations for some of the hydrodynamic conditions reflected in field data, suggesting hindered settling is an important factor in their formation. The introduction of density stratification reduces near surface SSC creating steeper SSC gradients in the upper half of the flow, for a weak current with waves.

Abstract:
Recent estimates of global sea level rise indicate mean values around 3.1 mm yr"1. As a result, many coastlines face an increasing risk of coastal erosion, and the threat of flooding is becoming a major concern. Unfortunately, coastal defences can be very costly with recent estimates as high as £5000 per metre length of seawall in the UK. There is a need to consider more economically feasible options, and by accounting for the ability of saltmarshes to absorb wave energy, reduce flow velocities and stabilise sediments, the costs of coastal defence structures may be significantly reduced. But first, an improved understanding of the implications of saltmarsh vegetation on hydrodynamics is fundamental to their inclusion in the design of coastal protection schemes. This includes the influence of saltmarsh vegetation on velocity and turbulence structures and the drag forces that arise due to the obstruction to the flow created by the vegetation. Two contrasting areas of coastal saltmarsh were selected for the location of a field survey to identify typical field conditions, such as bed gradients, submergence levels, vegetation types and densities. The two sites differ in that the first was non- grazed, while the second was heavily grazed to assess the impact of sheep farming on vegetation characteristics. The vegetation species, stem densities and submergence levels observed during the field survey were used as a guideline for designing a series of laboratory experiments to investigate the impact of saltmarsh vegetation on hydrodynamics. Uniform cylinder models are widely used to simulate vegetation canopies in hydrodynamic studies, yet the cylinder model can lead to an oversimplification of vegetation morphology. A comparison was made by conducting experiments under uniform flow conditions where uniform cylinder arrays and vegetation canopies were installed onto a flume bed at stem densities of 800, 1160 and 1850 stems m*2. There were differences in velocity and turbulence structures through the two types of canopy. For the same stem density, the proportion of the total flow passing through the canopy region was approximately 10% greater for the uniform cylinder arrays. The foliage found in the upper part of vegetation canopies resulted in a considerably higher level of obstruction and contributed towards reducing velocities and Reynolds stresses within the canopy. Reynolds stress penetration depths were up to 15 times greater for the uniform cylinder arrays compared to the vegetation canopies. Computational fluid dynamics models can be a useful tool for predicting the impact of saltmarsh vegetation on hydrodynamics for coastal management. Applying such models to vegetated flows requires knowledge of the drag coefficient to determine the drag term in the Navier-Stokes equations. However, in the absence of measured data, such models are often applied with the assumption that the drag coefficient is constant in value, and commonly used values include '1.0' and '1.2'. Such assumptions may be easily linked to the uniform cylinder model. However, drag coefficients calculated for Common Cordgrass ranged between 0.4 and 1.7. Values were dependent on numerous parameters, including the Reynolds number, the submergence level, the stem density and the maturity of the vegetation. Instead of the traditional drag-force approach for determining canopy hydrodynamics, a method for predicting velocity and turbulence structures based on the projected area of the vegetation was proposed. For the emergent canopy, the mean velocity was estimated by relating to a reference canopy of known projected area and mean velocity. For the submerged canopy, the surface flow layer velocity was determined effectively using the Manning's roughness approach and the depth- averaged canopy velocity was a function of the surface layer velocity and the canopy density. Velocity profile shapes for both canopies were obtained by linking the mean canopy velocity to the projected area profile. Reynolds stresses for the emergent canopy and lower part of the submerged canopy were negligible and a function of depth-averaged canopy velocity. For the upper part of a submerged canopy, Reynolds stresses were a function of the depth-averaged surface layer and canopy velocities. The proportion of the submerged canopy region experiencing higher Reynolds stresses is also a function of the vegetation density.

A espÃcie Holothuria grisea, pertencente à FamÃlia Holothuriidae, apesar de ser comum na costa brasileira, ainda apresenta uma lacuna de conhecimento em relaÃÃo aos seus aspectos ecolÃgicos. O objetivo do presente trabalho foi verificar variaÃÃes temporais na abundÃncia, densidade e estrutura populacional de Holothuria grisea, bem como verificar seu padrÃo de distribuiÃÃo espacial. O local de estudo foi a Praia de BitupitÃ, localizada no municÃpio de Barroquinha - CearÃ, distante aproximadamente 420 km de Fortaleza. As coletas ocorreram no perÃodo de janeiro a dezembro de 2011, durante as marÃs diurnas de sizÃgias na zona entremarÃs de um recife de arenito da referida praia. A metodologia baseou-se em um transecto perpendicular à linha da praia com 160 metros de comprimento marcando-se seis pontos distantes entre si dez metros. Foi utilizado um quadrado de 4 m em cada ponto marcado. Os espÃcimes encontrados nestes quadrantes foram contados, medidos e pesados. Foram mensurados os parÃmetros abiÃticos salinidade, temperatura, pH e oxigÃnio dissolvido, com auxÃlio de um refratÃmetro, termÃmetro, pHmetro e oxÃmetro, respectivamente. Foi realizada anÃlise granulomÃtrica do sedimento no perÃodo chuvoso e de estiagem. O padrÃo de distribuiÃÃo espacial encontrado foi do tipo agregado corroborando com a literatura existente. Observou-se um total de 620 indivÃduos de H. grisea no perÃodo estudado. A pluviosidade influenciou na abundÃncia de H. grisea, uma vez que no perÃodo chuvoso obteve-se maior abundÃncia comparada ao perÃodo de estiagem. Houve correlaÃÃo positiva entre a pluviosidade e abundÃncia (r= 0,514). A mÃdia de densidade anual foi de 0.54  0.14 ind/mÂ. NÃo houve diferenÃa entre as mÃdias de densidades ao longo dos meses, nem entre os dados agrupados do perÃodo chuvoso e de estiagem; estes fatos podem ser explicados pelo padrÃo de distribuiÃÃo agregada da populaÃÃo. O tamanho mÃdio observado dos indivÃduos de H. grisea foi 12,89  2,42 cm, com uma distribuiÃÃo de frequÃncia unimodal. O peso mÃdio observado foi 90,28  30,29 g apresentando uma distribuiÃÃo de frequÃncia unimodal. Houve correlaÃÃo positiva entre peso e tamanho dos indivÃduos da populaÃÃo O presente estudo, contribuiu para novos conhecimentos em ecologia dos Holothuroidea presentes em Ãguas tropicais.
The species Holothuria grisea, belonging to the Family Holothuriidae, despite being common in Brazilian coast, still has a big gap in relation to its ecological aspects. The aim of this study was to assess temporal variations in abundance, density and population structure of Holothuria grisea, as well as verify their spatial distribution pattern. The study site was the Bitupità Beach, located in the municipality of Barroquinha - CearÃ, distant about 420 km from Fortaleza. The samples were collected during diurnal spring tides in the intertidal zone on a rock shore of Bitupità Beach during January to December 2011. The methodology was based on a transect perpendicular to the beach with 160 meters long by scoring six points among ten meters. We used a square of 4 m at each marked point and the Holothuria grisea found in this square were counted, measured and weighed. The abiotic parameters were measured such as salinity, temperature, pH and dissolved oxygen. Analyses of sediment were performance in the rainy season and the dry season of 2011. The spatial distribution pattern found for Holothuria grisea was aggregate. We observed a total of 620 individuals of H. grisea during the study period. Rainfall influenced the abundance of H. grisea, since the rainy season yielded greater abundance compared to the dry season. We found a positive correlation between rainfall and abundance (r= 0.514). The average annual density was 0.54  0.14 ind / mÂ. There was no difference between the mean densities over months or between the wet and dry seasons, this fact can be explained by the spatial distribution of the aggregate population. The average size observed was 12.89 cm  2.42 cm frequency unimodal distribution. The average weight was observed  30.29 g 90.28 g showing a frequency distribution unimodal. There was a positive correlation between weight and size of the population. This study has contributed to new knowledge in Holothuroidea ecology in tropical waters.

Abstract:
As an important technique for corrosion control in marine environment, Cathodic Protection (CP) should be applied with a full understanding of environmental conditions and a good consideration of current requirements. Early studies on different kinds of steel specimens in the intertidal zone show severe corrosion losses. Nevertheless, there is evidence that CP can work in these regions of a steel structure because electrolyte pathway can remain some time on thin wetted surfaces when tides recede. This research aims to study corrosion activities and their behaviour under the influence of CP in a thin layer of electrolyte as a simulation of the inter-tidal zone. By means of a mechanical vibrating probe, Scanning Vibrating Electrode Technique (SVET) may be used to study local activities at coating defects in a thin electrolyte layer. The effect of CP on the local currents at the defect site was confirmed by SVET and, significantly, the development of calcareous films under these conditions in seawater was also observed. Such films are found to be effective in the absence of cathodic polarisation and only failed after damage. In order to explore the performance of applying CP, a Finite Element (FE) model of electrically connected zinc and steel samples beneath a specific thickness of electrolyte has been created, with full polarisation curves implemented for each metal based on experimental results obtained. The influence of the electrolyte conductivity and the geometry of the electrodes has also been considered. A comparison can then be made between experimental investigation and computational modelling of this corrosion cell. Epoxy-coated and uncoated mild steel samples obtained in the simulated tidal facility were also investigated. The formation of calcareous films was confirmed. Calcareous films were protective under these intermittent wetting conditions. Techniques used to understand the performance include optical observation, Scanning Electron Microscopy (SEM) together with Energy Dispersive X-ray (EDX) and X-ray Diffraction (XRD) analysis.

Abstract:
Terrestrial organic matter (TOM) constitutes an important source of energy in many aquatic environments (streams, lakes, wetlands). This is the first study to examine the role of TOM in food webs of the rocky intertidal zone. We compared the consumption of red alder leaves (Alnus rubra) to common marine sources of drifting detritus along the southern Oregon coast (Nereocystis luetkeana, Phyllospadix spp., and Fucus gardneri). We used short term (hours to days) and long term (months) feeding experiments to compare the rate of consumption among each plant species during the Spring and Fall of 2014 and 2015. In addition, we quantified the amount of TOM in beach wrack and in the drift of two streams that flowed directly to the rocky intertidal zone. We also measured the food quality of each plant species (C:N and polyphenolic concentrations). On average, the two small streams in this study transported 1,113.6 kg AFDM/m3 of TOM per day during Fall leaf abscission to the rocky intertidal zone. Also, the biomass of terrestrial leaves in beach wrack varied from negligible (2.1 g AFDM) to the dominant source of detritus (60.7 g AFDM) depending on if it was the dominant riparian plant growing along the edges of the shore. Consistent with previous research, N. luetkeana was a high quality food (C:N = 15:1; polyphenolics = 418 mg/ml), whereas F. gardneri (C:N = 22:1; polyphenolics = 8098 mg/ml) was more recalcitrant. Phyllospadix spp. was puzzling because it had low concentrations of polyphenolics (800 mg/ml) but was not consumed. Alnus rubra had a high concentration of structural compounds (C:N = 33:1) and intermediate levels of polyphenolics (3,415 mg/ml after leaching). Both short term and long term experiments showed that the rates of consumption of Spring-shed, green leaves and freshly fallen brown leaves of A. rubra were intermediate between N. luetkeana and the less palatable marine species (F. gardneri and Phyllospadix spp.). Thus, A. rubra was eaten by common intertidal consumers and may constitute an important source of energy between brief inputs of more nutritious marine resources (e.g. N. luetkeana).

The aim of this study was to assess temporal variations in abundance, density and population structure of Holothuria grisea, as well as verify their spatial distribution pattern. The study site was the Bitupitá Beach, located in the municipality of Barroquinha - Ceará, distant about 420 km from Fortaleza. The samples were collected during diurnal spring tides in the intertidal zone on a rock shore of Bitupitá Beach during January to December 2011. The methodology was based on a transect perpendicular to the beach with 160 meters long by scoring six points among ten meters. We used a square of 4 m² at each marked point and the Holothuria grisea found in this square were counted, measured and weighed. The abiotic parameters were measured such as salinity, temperature, pH and dissolved oxygen. Analyses of sediment were performance in the rainy season and the dry season of 2011. The spatial distribution pattern found for Holothuria grisea was aggregate. We observed a total of 620 individuals of H. grisea during the study period. Rainfall influenced the abundance of H. grisea, since the rainy season yielded greater abundance compared to the dry season. We found a positive correlation between rainfall and abundance (r= 0.514). The average annual density was 0.54 ± 0.14 ind / m². There was no difference between the mean densities over months or between the wet and dry seasons, this fact can be explained by the spatial distribution of the aggregate population. The average size observed was 12.89 cm ± 2.42 cm frequency unimodal distribution. The average weight was observed ± 30.29 g 90.28 g showing a frequency distribution unimodal. There was a positive correlation between weight and size of the population. This study has contributed to new knowledge in Holothuroidea ecology in tropical waters.
A espécie Holothuria grisea, pertencente à Família Holothuriidae, apesar de ser comum na costa brasileira, ainda apresenta uma lacuna de conhecimento em relação aos seus aspectos ecológicos. O objetivo do presente trabalho foi verificar variações temporais na abundância, densidade e estrutura populacional de Holothuria grisea, bem como verificar seu padrão de distribuição espacial. O local de estudo foi a Praia de Bitupitá, localizada no município de Barroquinha - Ceará, distante aproximadamente 420 km de Fortaleza. As coletas ocorreram no período de janeiro a dezembro de 2011, durante as marés diurnas de sizígias na zona entremarés de um recife de arenito da referida praia. A metodologia baseou-se em um transecto perpendicular à linha da praia com 160 metros de comprimento marcando-se seis pontos distantes entre si dez metros. Foi utilizado um quadrado de 4 m² em cada ponto marcado. Os espécimes encontrados nestes quadrantes foram contados, medidos e pesados. Foram mensurados os parâmetros abióticos salinidade, temperatura, pH e oxigênio dissolvido, com auxílio de um refratômetro, termômetro, pHmetro e oxímetro, respectivamente. Foi realizada análise granulométrica do sedimento no período chuvoso e de estiagem. O padrão de distribuição espacial encontrado foi do tipo agregado corroborando com a literatura existente. Observou-se um total de 620 indivíduos de H. grisea no período estudado. A pluviosidade influenciou na abundância de H. grisea, uma vez que no período chuvoso obteve-se maior abundância comparada ao período de estiagem. Houve correlação positiva entre a pluviosidade e abundância (r= 0,514). A média de densidade anual foi de 0.54 ± 0.14 ind/m². Não houve diferença entre as médias de densidades ao longo dos meses, nem entre os dados agrupados do período chuvoso e de estiagem; estes fatos podem ser explicados pelo padrão de distribuição agregada da população. O tamanho médio observado dos indivíduos de H. grisea foi 12,89 ± 2,42 cm, com uma distribuição de frequência unimodal. O peso médio observado foi 90,28 ± 30,29 g apresentando uma distribuição de frequência unimodal. Houve correlação positiva entre peso e tamanho dos indivíduos da população O presente estudo, contribuiu para novos conhecimentos em ecologia dos Holothuroidea presentes em águas tropicais.

Abstract:
Turbo smaragdus is very abundant in intertidal algal beds. Grazing effects by this turbinid snail were tested on two intertidal platforms, at Kaikoura and Moeraki (on the east coast of the South Island). A caging experiment was used to test the effects of several factors. These were snail density, algal assemblage type, shore height and platforms. These incorporated biological variables and spatial scales. The experiment was monitored monthly over a year for the percentage cover of all macro algae and several other variables. T. smaragdus grazing affected the abundance of many species, particularly when snails were included at high densities. At their highest density, T. smaragdus excluded ephemeral algal species. Grazing by T. smaragdus reduced the abundance of juvenile Horinosira banksii in the total removal treatments, except in the presence of alternative food sources, such as ephemeral algae. There were differences in grazing effects between platforms. T. smaragdus grazing had more impact on the recolonisation of bare patches by articulated coralline algae at Moeraki than at Wairepo. This was because algae were slower to re-establish at Wairepo, possibly due to climatic differences between the sites. T. smaragdus, at higher densities, may maintain bare patches within H. banksii-dominated assemblages by consuming early-colonising species and preventing recruitment of H. banksii. Grazing by T. smaragdus has considerable impact on algal assemblage species composition and the sequence of algal assemblage development.

Full text
Abstract:
L’étude biogéochimique des sédiments sableux perméables est un domaine nouveau : le rôle de ces environnements dans les cycles biogéochimiques a longtemps été négligé en raison de leur pauvreté en matière organique et de la complexité des processus transitoires s’y déroulant. Les plages sableuses sont en effet soumises à de nombreux forçages physiques, dont la marée, la houle et la connexion avec l’aquifère continental. Le processus d’advection y est le mode de transport dominant. De grands volumes d’eau de mer chargée en matière organique sont plus ou moins filtrés par les sédiments perméables intertidaux. Le principal objectif de cette thèse était de caractériser les processus biogéochimiques induits par la recirculation de l’eau de mer et les apports d’eau douce dans la zone intertidale dans le cas d’une plage soumise à de fortes conditions hydrodynamiques : la plage du Truc Vert. Un suivi saisonnier des propriétés physico-chimiques des eaux porales a montré que les processus de respiration aérobie interviennent en zone intertidale, dans la lentille de recirculation de l’eau de mer. A l’échelle du littoral aquitain, ces processus représentent un apport annuel de 610 tonnes de nitrate et de 4400 tonnes de carbone inorganique dissous pour l’océan côtier, soit l’équivalent des apports de la Leyre, un petit fleuve drainant un bassin versant de 2000 km2 au sud-est du Bassin d’Arcachon. La macrofaune benthique est dominée par les Crustacés. Ces individus sont caractéristiques de ces milieux complexes, qu’ils subissent mais ne contrôlent pas : la macrofaune benthique contribue faiblement aux processus de respiration aérobie. Seuls 2% du déficit en oxygène des eaux porales du bas de plage leur est attribué en moyenne : les flux biogéochimiques observés en zone intertidale sont donc majoritairement induits par les processus de respiration aérobie des micro-organismes présents dans le sédiment. Soutenus par l’apport régulier d’oxygène dissous dans le milieu poral à chaque marée, ces processus sont également contrôlés par la température et la variabilité des apports de matière organique.Le déploiement de sondes autonomes dans le sédiment de la zone intertidale a également permis de préciser la variabilité à court terme des propriétés des eaux porales. L’extension de la lentille intertidale de recirculation de l’eau de mer est ainsi variable en fonction du marnage et les teneurs en oxygène mesurées en un point fixe de la plage varient légèrement en fonction de ce cycle. Ce travail a donc permis de démontrer que les processus de respiration aérobie varient principalement à l’échelle saisonnière. L’impact ponctuel et local des conditions météorologiques et de la houle a également été mis en évidence. Nous avons démontré l’existence d’un estuaire souterrain sous la plage du Truc Vert. La dynamique de ce système a été explorée grâce à l’installation de piézomètres en haut de plage. L’apport d’eaux douces continentales représente une source supplémentaire de nitrate et de carbone inorganique dissous pour l’océan côtier. L’étude biogéochimique de la nappe phréatique en arrière dune indique l’existence d’un découplage entre le front salin et le front redox au sein de l’estuaire souterrain, ainsi que l’existence d’un intense dégazage de CO2 au niveau de la dune.Les travaux réalisés durant cette thèse permettent de mieux comprendre les processus à l’œuvre dans les sédiments sableux des plages exposées et permettront ainsi le développement de modèles numériques complexes liant hydrologie et biogéochimie. Ils entraînent également de nombreuses perspectives à propos du rôle des plages sableuses à l’échelle locale (en cas de pollution par exemple) mais aussi sur les cycles biogéochimiques globaux, notamment en lien avec le réchauffement climatique et l’élévation du niveau marin (rejets de CO2, salinisation des aquifères côtiers)
Biogeochemical studies in permeable sandy sediments are recent: the role of these environments in biogeochemical cycles was neglected because of their poverty in organic matter and the complexity of transient processes affecting them. Sandy beaches are subject to various physical forcings like tide, waves and connexion with continental groundwaters. Advection is the leading mode of transport. Huge volumes of organic matter-bearing seawater are potentially filtered by permeable intertidal sediments. The main objective of this study was to characterize biogeochemical processes induced by seawater recirculation and groundwater discharge in the intertidal zone of an exposed beach: the Truc Vert beach.Seasonal monitoring of pore water properties showed that aerobic respiration processes occurred in the seawater recirculation plume. Extrapolated to the 240 km-long Aquitanian coast, these processes represent each year an annual release of 610 tons of nitrate and 4400 tons of dissolved inorganic carbon, i.e. the equivalent of the Leyre input, a small river draining a catchment area of 2000 km2 at the southeast part of the Arcachon lagoon.The benthic macrofauna is dominated by Crustaceans. These organisms have a low impact on biogeochemical cycles: the contribution of benthic macrofauna on oxygen deficits observed in the lower beach pore waters is insignificant (< 2%). Biogeochemical fluxes observed in the intertidal zone are mainly induced by the aerobic respiration of microorganisms living in the sediment. Supported by regular tidal inputs of dissolved oxygen on the pore space, these processes varied seasonnally with temperature and organic matter availability.The deployment of autonomous probes into the sediment of the intertidal zone allowed us to clarify the short-term variability of pore water properties. Extension of the intertidal saline plume evolved with the tidal amplitude. Oxygen levels measured at a given point of the beach varied slightly with the lunar cycle. This work showed that aerobic respiration processes varied mainly at the seasonal scale. The local impact of weather and swell was also evidenced.We showed the presence of a subterranean estuary in the Truc Vert beach and its dynamics was explored through the deployment of wells in the upper beach. The input of continental freshwater represents an additional source of nitrate and dissolved inorganic carbon in the coastal ocean. Chemical properties of the fresh groundwater located upstream the beach indicated a decoupling between the salinity gradient and the redox bareer within the subterranean estuary, as well as an intense CO2 degassing at the dune.This study allows to better understand the processes occuring in sandy sediments of exposed beaches and will allow to develop complex numerical models linking hydrological and biogeochemical processes. This work also provides many perspectives on the role of sandy beaches, both locally (in case of pollution, for example) and on global biogeochemical cycles, especially in relation to global warming and sea-level rise (CO2 emissions and seawater intrusion in coastal aquifers)

Abstract:
Os ecossistemas costeiros sofrem impactos antrópicos de fontes diversas, entre eles os despejos de efluentes, que podem potencializar o desenvolvimento de produtores primários em costões rochosos resultante do enriquecimento por nutrientes. Ao mesmo tempo, o crescimento dos produtores pode ser controlado pela presença dos herbívoros. No presente estudo buscamos descrever o efeito dos despejos de efluentes sobre o acúmulo de biofilme em costões rochosos, sob diferentes níveis de despejos de efluentes em uma área subtropical (São Paulo, Brasil), bem como o efeito dos efluentes sobre as lapas. Estimamos a biomassa do biofilme in situ, por medidas indiretas de NDVI e por análises taxonômicas de amostras fixadas. A estrutura populacional de lapas foi descrita por contagem e medição do comprimento da concha. Um experimento em campo foi realizado sob presença e ausência de efluentes, bem como presença e ausência de lapas. Observamos que o efeito de efluentes potencializa o acúmulo de biofilme, entretanto não observamos um consumo significativo das lapas sobre o biofilme. O tamanho e densidade de lapas não foram alteradas pelo gradiente de efluentes. Em geral, foi observada uma predominância de diatomáceas em relação às cianobactérias, o que pode diferir da tendência de dominância de cianobactérias verificada em outras regiões. É importante ressaltar a importância de outros pastadores sobre o desenvolvimento de biofilme, não considerados neste estudo, além da alta variabilidade temporal e espacial que as comunidades de biofilme apresentam. Ressaltamos a importância da aplicação de organismos bentônicos como indicadores da qualidade do ambiente.
Coastal ecosystems suffer anthropogenic impacts from many sources such as sewage disposal, which may potencialize de primary productors growth in rocky shores. In the same time, this growth amy be controlled by grazers. In this study we aimed to investigate the biofilm accumulation in rocky shores under different level of sewage disposal in a subtropical area (São Paulo State, Brazil), and its influence on the grazers. The biofilm biomass was estimated in situ indirectly by NDVI measures and taxonomic analysis of fixed samples. The size structure of limpets was described through counting and measurement of the shell length. We also performed a field experiment under presence and ausence of sewage, as presence and ausence of limpets. We observed a sewage effect improve the biofilm accumulation, but the limpets did not have a clear control on the biofilm growth. No clear effect of sewage disposal was verified on the size and density of limpets. In general, we observed a domination of diatoms relative to cianobacterias, which could differ of the trend observed in another sites. It is noteworthy that the possible effects of other grazers on the biofilm were not quantified and the high temporal and spatial variability of biofilm communities. We emphasize the importance of studies that use benthic organisms as environmental quality indicators.

Abstract:
Wave forces on slender horizontal and vertical cylinders are normally estimated using Morison equation (1950). When a cylinder is near the free surface, it experiences the slamming force. Wave slamming on horizontal cylinders of any ocean structure is crucial to its design. API Recommended Practice 2A-WSD (2000) recommends slamming coefficient Cs equal to π for circular cross sectional cylinders near the still water level. The shape of the member (circular, rectangular or square) is also expected to alter the values of Cs. The horizontal cylinders in the inter tidal zone for Port craft jetties are subjected not only to slamming force in the vertical direction but also to berthing force in the horizontal direction. If two cylinders are kept in close spacing, then the load on both cylinders will differ compared to force on a single cylinder. The effect of tidal variation on slamming forces needs thorough investigation. The comparison of single circular cylinder and twin circular cylinder with a clear spacing equal to diameter of cylinder in regular waves is discussed in this paper.

Abstract:
The main recommendations of the panel report can be summarised under four headings: 1. From Source to Sea: River systems, from their source to the sea and beyond, should form the focus for research projects, allowing the integration of all archaeological work carried out along their course. Future research should take a holistic view of the marine and maritime historic environment, from inland lakes that feed freshwater river routes, to tidal estuaries and out to the open sea. This view of the landscape/seascape encompasses a very broad range of archaeology and enables connections to be made without the restrictions of geographical or political boundaries. Research strategies, programmes From Source to Sea: ScARF Marine and Maritime Panel Report iii and projects can adopt this approach at multiple levels; from national to site-specific, with the aim of remaining holistic and cross-cutting. 2. Submerged Landscapes: The rising research profile of submerged landscapes has recently been embodied into a European Cooperation in Science and Technology (COST) Action; Submerged Prehistoric Archaeology and Landscapes of the Continental Shelf (SPLASHCOS), with exciting proposals for future research. Future work needs to be integrated with wider initiatives such as this on an international scale. Recent projects have begun to demonstrate the research potential for submerged landscapes in and beyond Scotland, as well as the need to collaborate with industrial partners, in order that commercially-created datasets can be accessed and used. More data is required in order to fully model the changing coastline around Scotland and develop predictive models of site survival. Such work is crucial to understanding life in early prehistoric Scotland, and how the earliest communities responded to a changing environment. 3. Marine & Maritime Historic Landscapes: Scotland’s coastal and intertidal zones and maritime hinterland encompass in-shore islands, trans-continental shipping lanes, ports and harbours, and transport infrastructure to intertidal fish-traps, and define understanding and conceptualisation of the liminal zone between the land and the sea. Due to the pervasive nature of the Marine and Maritime historic landscape, a holistic approach should be taken that incorporates evidence from a variety of sources including commercial and research archaeology, local and national societies, off-shore and onshore commercial development; and including studies derived from, but not limited to history, ethnology, cultural studies, folklore and architecture and involving a wide range of recording techniques ranging from photography, laser imaging, and sonar survey through to more orthodox drawn survey and excavation. 4. Collaboration: As is implicit in all the above, multi-disciplinary, collaborative, and cross-sector approaches are essential in order to ensure the capacity to meet the research challenges of the marine and maritime historic environment. There is a need for collaboration across the heritage sector and beyond, into specific areas of industry, science and the arts. Methods of communication amongst the constituent research individuals, institutions and networks should be developed, and dissemination of research results promoted. The formation of research communities, especially virtual centres of excellence, should be encouraged in order to build capacity.
