Abstract:
ABSTRACT To evaluate the role of seafoods in the epidemiology of human listeriosis and the role of the processing environment as a source ofListeria monocytogenes in seafood products, 305 L. monocytogenes isolates were characterized by multilocus enzyme electrophoresis using 21 genetic loci and restriction enzyme analysis of total DNA. Forty-four isolates were recovered from patients in Norway; 93 were isolated from seafoods, seafood-processing environments, and seawater from 55 different producers; and the remaining 168 isolates originated from six seafood-processing plants and one transport terminal examined in detail for L. monocytogenes. The patient isolates fell into 11 electrophoretic types, with four of them being responsible for 77% of the listeriosis cases in 1992 to 1996. Isolates from Norwegian seafoods and processing environments showed great genetic diversity, indicating that seafoods and seafood-processing environments do not offer a niche for specificL. monocytogenes strains. On the other hand, isolates from individual processing plants were genetically more homogenous, showing that plants are likely to be colonized with specific subclones ofL. monocytogenes. The isolation of identical subclones ofL. monocytogenes from both human patients and seafoods, including ready-to-eat products, suggests that such products may have been possible sources for listeriosis cases in Norway.

Abstract:
The present study investigates the supply chain for seafood industries in Korea. Unlike previous studies, which analyze the supply chain from input users’ perspective only, the present study examines the supply chain from both input users’ (backward linkage) and input suppliers’ (forward linkage) perspectives. In doing so, this study utilizes structural path analyses (SPAs) to scrutinize the specific paths along which the effects of a shock to a seafood industry are transmitted in both backward and forward directions. This study executes these two types of SPAs (backward linkage and forward linkage SPAs) for three seafood industries in Korea that include wild fisheries, aquaculture, and seafood processing, thus depicting a more detailed and complete picture of the mechanisms through which the influences of the seafood industries spill over to the rest of the economy. One important finding is that our SPAs are able to identify a number of seemingly unlikely non-seafood industries that play a critical role in transmitting the effects of a shock to a seafood industry.

Abstract:
We use contingent behavior analysis to study the effects of pfiesteria-related fish kills on the demand for seafood in the Mid-Atlantic region. We estimate a set of demand difference models based on individual responses to questions about seafood consumption in the presence of fish kills and with different amounts of information provided about health risks. We use a random-effects Tobit model to control for correlation across each observation and to account for censoring. We find that (i) pfiesteria-related fish kills have a significant negative effect on the demand for seafood even though the fish kills pose no known threat to consumers through seafood consumption, (ii) seafood consumers are not responsive to expert risk information designed to reassure them that seafood is safe in the presence of a fish kill, and (iii) a mandatory seafood inspection program largely eliminates the welfare loss incurred due to misinformation.

Abstract:
This paper addresses the need to establish a fast, effective and reliable method for collecting fish and seafood consumption data at the village level. Two different approaches, a community participatory and a classical survey one were tested and validated against each other. Using fully structured questionnaire surveys also reliability of results obtained from household and individual interviews were compared. Furthermore, taking fresh fish consumption as an example, three different methods were assessed to approximate best per capita consumption. Approaches and methods are validated in terms of time and human resource requirements, and data quality by comparing data sets obtained in Polynesian and Melanesian communities. Adding efficiency criteria, adoption of household average consumption surveys is concluded to best combine reliable data and least time and financial requirements. Per capita fresh fish consumption was found to best estimated using a simplified WHO system that takes into account gender-age correction factors.

Abstract:
This study seeks to identify interproduct relationships between domestic catfish and a representative selection of imported seafood. In doing so, this study uses multivariate cointegration and structural analyses. Multivariate cointegration analysis suggests that six imported seafood product groupings form a common market with domestic catfish. Structural analysis reveals that 1) domestic and imported catfish are net and gross quantity substitutes; 2) domestic catfish and imported seafood are normal goods; 3) six imported seafood products are identified as gross quantity substitutes for domestic catfish; and 4) according to the derived Allais coefficients, interaction intensities of imported seafood for domestic catfish (from greatest to least) are as follows: tuna, shrimp, salmon, tilapia, catfish, and trout.

Abstract:
Background: Seafood is an important source of omega-3 fatty acids, which have been associated with improved oocyte quality and embryo morphology in some studies. However, seafood is also a source of persistent organic pollutants and heavy metals, which may adversely affect fecundity. Previous studies of seafood intake and fecundity have generated inconsistent results. Methods: In two prospective cohort studies of 7836 female pregnancy planners from Denmark (Snart Foraeldre, n = 2709) and North America (PRESTO, n = 5127), we evaluated the association of dietary intake of total seafood and marine-sourced long-chain omega-3 fatty acids (eicosapentaenoic acid, docosahexaenoic acid, and docosapentaenoic acid) with fecundability. Participants completed a baseline questionnaire on sociodemographics, behavioral factors, anthropometrics, and medical history, and a food frequency questionnaire. Pregnancy status was updated bimonthly for up to 12 months or until reported conception. We estimated fecundability ratios (FRs) and 95% confidence intervals (CIs) using proportional probabilities regression models, adjusted for energy intake and other potential confounders. We restricted analyses to women with ≤6 menstrual cycles of attempt time at enrollment. Results: Intake of total seafood or marine-sourced long-chain omega-3 fatty acids was not appreciably associated with fecundability in either cohort (≥200 vs. <50 g/week total seafood: FR = 0.94, 95% CI: 0.79–1.10 in Snart Foraeldre; FR = 1.00, 95% CI: 0.90–1.13 in PRESTO; marine fatty acids: ≥90th vs. <25th percentile: FR = 1.00, 95% CI: 0.85–1.18 in Snart Foraeldre; FR = 0.97, 95% CI: 0.86–1.09 in PRESTO). In PRESTO, where we collected additional data on seafood preparation, we observed an inverse association between fecundability and fried shellfish (≥10 g/week vs. none: FR = 0.77, 95% CI: 0.61–0.98), but not unfried shellfish (≥20 g/week vs. none: FR = 0.98, 95% CI: 0.89–1.07); in Snart Foraeldre, there was no association with total shellfish intake. Conclusions: We found little association between seafood intake and fecundability overall, but greater intake of fried shellfish was associated with reduced fecundability among North American participants.

Abstract:
Seafood provides n-3 long-chain PUFA (n-3 LC-PUFA), vitamins and minerals, which are essential to maintain good health. Moreover, seafood is a source of contaminants such as methylmercury, arsenic and persistent organic pollutants that may affect health. The aim of the present study was to determine in what quantities seafood consumption would provide nutritional benefits, while minimising the risks linked to food contaminants. Seafood was grouped into clusters using a hierarchical cluster analysis. Those nutrients and contaminants were selected for which it is known that seafood is a major source. The risk–benefit analysis consisted in using an optimisation model with constraints to calculate optimum seafood cluster consumption levels. The goal was to optimise nutrient intakes as well as to limit contaminant exposure with the condition being to attain recommended nutritional intakes without exceeding tolerable upper intakes for contaminants and nutrients, while taking into account background intakes. An optimum consumption level was calculated for adults that minimises inorganic arsenic exposure and increases vitamin D intake in the general population. This consumption level guarantees that the consumer reaches the recommended intake for n-3 LC-PUFA, Se and I, while remaining below the tolerable upper intakes for methylmercury, Cd, dioxins, polychlorobiphenyls, Zn, Ca and Cu. This consumption level, which is approximately 200 g/week of certain fatty fish species and approximately 50 g/week of lean fish, molluscs and crustaceans, has to be considered in order to determine food consumption recommendations in a public health perspective.

AbstractAttributes for two value-added seafood products derived from underutilized crawfish are analyzed using conjoint data from seafood restaurants in the southern region of the United States. Preferences for the products' form, price, and flavor attributes were tested. Statistical tests revealed that the attribute interactions were not significant, and part-worth utilities for all main effects were estimated using an additive preference model. Results indicate that the new crawfish products should be marketed as a high-quality fresh soup base or seafood stuffing, priced between 30% and 50% of the cost of fresh crawfish tail meat.

Abstract:
This study aims to determine the attributes that affect the level of customer satisfaction and the value of the level of customer satisfaction in the Bandar Djakarta restaurant of Alam Sutera of Tangerang City. The method used in this study is the method of importance-performance analysis to determine the attributes that affect customer satisfaction and the customer satisfaction index to determine the value of overall customer satisfaction. After all the data has been processed, the data will be analyzed descriptively. The technique used to take samples in this study is accidental sampling. Sampling was carried out for four weeks in July 2019 with a total of 85 respondents. The results of this study indicate that the attributes that make consumers feel satisfied are the variety of food, product taste, food hygiene, safety guarantees, the hospitality of the waitress, queuing time, room comfort and room cleanliness. While the attributes that make consumers feel less satisfied are the cleanliness of eating utensils and the speed at which food is served. The overall value of customer satisfaction is at 85,00.

Abstract:
Globally there have been many challenges in establishing effective food safety control systems. Of particular interest to the Sultanate of Oman is the control of the safety and quality of seafood for its importance to the national economy, food security and trade. The research focused on the particular issue of food safety management systems (including the application of the Hazard Analysis Critical Control Point (HACCP)) system within the Omani seafood processors. To understand the whole context, a wider review was initially conducted which looked into the whole structure of food control in Oman including the legal documents and the administrative structures. The evidence indicates that there is no unified national food safety agency and that current laws and regulations are shared across various governmental authorities. By investigating the various challenges, weaknesses and strengths of the existing system it is noted that there are still deficiencies in comparison to international guidance. Subsequently the structure of the seafood supply chain was analysed and a survey was conducted to assess the issues pertinent to HACCP implementation in the seafood industry and the role of the regulatory authorities in governing the safety of seafood products. The survey identified more precisely the benefits and barriers of implementing the HACCP system for the HACCP processors and the non-HACCP processors, which are usually small industry. In conclusion, the research has shown the importance of adopting strategies to enhance safety and quality requirements from farm to fork covering all aspects of seafood harvesting, processing and distribution regardless of the target markets. A legal requirement to adopt HACCP systems and the application of related food safety management systems (FSMSs) and their pre-requisites programmes is recommended. It should be imposed on all seafood processors regardless of their markets to ensure conformity with national and international requirements.

Abstract:
Seafood is known for its valuable and healthy nutrients; however scientific studies demonstrated the unavoidable presence of contaminants in fish and shellfish. Authorities strongly recommend fish consumption, especially to sensible groups of population (pregnant or nursing women, infants and children), and ask the scientific community for novel and coherent data to establish clear guidelines for consumers. There is also a serious need to extend the monitoring to emerging chemical pollutants, other than methylmercury, dioxins and polychlorinated biphenyls, to better understand the level of seafood contamination. An innovative UHPLC-MS/MS method for the quantification of glycine betaine (GB) in Tapes philippinarum was developed and validated, taking the 2002/657 European Decision as guideline; GB is an endogenous osmolyte abundant in molluscs, and represent a vital methylating agent in humans. Moreover, a previously developed and validated UHPLC-MS/MS method was used to conduct a preliminary monitoring of the presence of the two main perfluorinated contaminants, perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA), in six fish species from Italian markets (Dicentrarchus labrax, Merluccius merluccius, Mugil cephalus, Pleuronectes platessa, Scomber scombrus and Sparus aurata). The daily contribution of seafood to PFOS and PFOA dietary intake in Italian population was calculated and data were compared to the corresponding Tolerable Daily Intakes established by EFSA in 2008. Results revealed that the risk of contamination related to fish consumption is unlikely, but suggested the need to conduct further surveys focused on certain species from different sampling site. Subsequently, a mono-specie monitoring was carried out in 140 farmed and wild subjects of Dicentrarchus labrax, from 14 different locations in the Mediterranean area. The obtained results showed that wild subjects are sensibly more contaminated than farmed ones, and that levels of fish contamination are strongly influenced by their geographical origin and the proximity to polluted areas.

Abstract:
Interest in converted waves (C-waves) has been growing significantly in recent yeas due to the advent of four-component (4C) ocean-bottom-cable (OBC) seismic recordings. This has changed the way geophysicists obtain fluid and lithology information about hydrocarbon reservoirs through joint P- and converted-wave analysis. Since 4C OBC surveys use conventional air-gun sources, which generate P-waves only, the shear-waves recorded by the 4C sensors on the ocean bottom are mode-converted shear-waves. The main focus of this thesis is to find ways to process and understand these mode-converted shear-waves in the presence of seismic anisotropy which is common in marine sediments. To this end, I examine and model the data characteristics of 4C seismic data, review the basic theory of converted-wave processing, develop new kinematic theories for converted-waves propagating in anisotropic, inhomogeneous media, and apply these new methods to field 4C data. I focus on two types of anisotropy: transverse isotropy with either a vertical (TIV) or horizontal (TIH) axis of symmetry. As an emerging technology, the characteristics of 4C seismic data have not been fully understood, and there are many acquisition related problems yet to be solved. The characteristics of 4C seafloor data have been studied by field data analysis and by synthetic modelling. I have found: 1) the water-column reverberations in the vertical geophone are much weaker than those in the hydrophone, because of the different sensor responses to the source- and receiver-side multiples; 2) the presence of a low shear-wave velocity gradient in the seabed prohibits P-to-S conversion, and this implies that most shear-waves recorded in 4C data are converted at deep reflector; 3) due to current sensor design, there is a shear-wave energy leakage from the inline horizontal geophone to the vertical geophone, resulting in geophone coupling problem. I have also studied the problem of sensor orientation and presented geophone orientation algorithms for both gimballed and non-gimballed geophone systems.

Abstract:
Depuis les séismes dévastateurs de 1999 d’Izmit et de Duzce, la partie immergée de la Faille Nord Anatolienne (FNA)en Mer de Marmara fait l’objet d’une intense surveillance. Malgré cela, la micro-sismicité demeure mal connue. Par ailleurs, alors que la connexion avec le système pétrolier du Bassin de Thrace est établie, le rôle du gaz sur la sismicité n’a pas été identifié.Dans ce travail, nous avons analysé des données d’OBS (Ocean Bottom Seismometers) acquises dans la partie ouest de la Mer de Marmara (en avril-juillet 2011 et septembre-novembre 2014), à partir de méthodes non-linéaires –NonLinLocet d’un modèle 3D de vitesses. Une grande partie de la sismicité se produit à des profondeurs inférieures à 6 km environ : le long de failles secondaires, héritées de l’histoire complexe de la FNA ; ou dans des couches de sédiments superficiels (< 1 km) riches en gaz. Cette sismicité superficielle semble être associée à des processus liés au gaz, déclenchés par les séismes profonds de magnitude M1 > 4.5 qui se produisent régulièrement le long de la MMF.Par ailleurs, 2 familles de signaux de courte durée (<1s), dits ≪ SDE ≫ (pour Short Duration Event) apparaissent sur les enregistrements : 1) les SDE se produisant à raison de quelques dizaines de SDE/jour, en réponse à des causes locales (i.e. bioturbation, activité biologique, micro-bullage de fond de mer, mouvements à l’interface eau/sédiment), etc ; 2) lesSDE se produisant par ≪paquets≫, dont certains sont enregistrés sur les 4 composantes (y compris l’hydrophone) et apparaissent de manière périodique, toutes les 1.8 s environ, en réponse à diverses causes qui restent à déterminer (parmi lesquelles : les mammifères marins ; l’activité humaine ; la sismicité ; le dégazage ; les ≪trémors≫ sismiques ; etc)
Since the devastating earthquakes of 1999, east of Istanbul, the submerged section of the North Anatolian Fault (NAF), in the Sea of Marmara (SoM) has been intensively monitored, mainly using land stations. Still, the micro-seismicity remains poorly understood. In addition, although the connection of the SoM with the hydrocarbon gas system from the Thrace Basin is now well established, along with the presence of widespread gas within the sedimentary layers, the role of gas on seismicity is still not recognized.Here, we have analyzed Ocean Bottom Seismometer (OBS) data from two deployments (April-July 2011 and September-November 2014) in the western SoM. Based on a high-resolution, 3D-velocity model, and on non-linear methods (NonLinLoc), our location results show that a large part of the micro-seismicity occurs at shallow depths (< 6 a 8 km): along secondary faults, inherited from the complex history of the North-Anatolian shear zone; or within the uppermost (< 1 km), gas-rich, sediment layers. Part of this ultra-shallow seismicity is likely triggered by the deep earthquakes of intermediate magnitude (Ml > 4.5) that frequently occur along the western segments of the MMF.In addition, OBSs also record at least two families of short duration (<1 sec) events (SDEs): 1) “background SDEs” occurring on a permanent, at a rate of a few tens of SDEs/day, resulting from many possible, local causes, e. g.: degassing from the seafloor, biological activity near the seabed, bioturbation, etc; 2) “swarmed SDEs”, among which some are recorded also on the hydrophone, and characterized by a periodicity of ~ 1.8 seconds. The causes of these SDEs still remain to be determined (among which: anthropogenic causes, marine mammals, gas emissions, regional seismicity, tremors from the MMF, etc)

Full text
Abstract:
Un sonar latéral de cartographie enregistre les signaux qui ont été rétrodiffusés par le fond marin sur une large fauchée. Les signaux sont ainsi révélateurs de l'interaction entre l'onde acoustique émise et le fond de la mer pour une large plage de variation de l'angle de rasance. L'analyse des statistiques de ces signaux rétrodiffusés montre une dépendance à ces angles de rasance, ce qui pénalise fortement la segmentation des images en régions homogènes. Pour améliorer cette segmentation, l'approche classique consiste à corriger les artefacts dus à la formation de l'image sonar (géométrie d'acquisition, gains variables, etc.) en considérant un fond marin plat et en estimant des lois physiques (Lambert, Jackson, etc.) ou des modèles empiriques. L'approche choisie dans ce travail propose de diviser l'image sonar en bandes dans le sens de la portée ; la largeur de ces bandes étant suffisamment faible afin que l'analyse statistique de la rétrodiffusion puisse être considérée indépendante de l'angle de rasance. Deux types d'analyse de texture sont utilisés sur chaque bande de l'image. La première technique est basée sur l'estimation d'une matrice des cooccurrences et de différents attributs d'Haralick. Le deuxième type d'analyse est l'estimation d'attributs spectraux. La bande centrale localisée à la moitié de la portée du sonar est segmentée en premier par un réseau de neurones compétitifs basé sur l'algorithme SOFM (Self-Organizing Feature Maps) de Kohonen. Ensuite, la segmentation est réalisée successivement sur les bandes adjacentes, jusqu'aux limites basse et haute de la portée sonar. A partir des connaissances acquises sur la segmentation de cette première bande, le classifieur adapte sa segmentation aux bandes voisines. Cette nouvelle méthode de segmentation est évaluée sur des données réelles acquises par le sonar latéral Klein 5000. Les performances de segmentation de l'algorithme proposé sont comparées avec celles obtenues par des techniques classiques.

Abstract:
Abstract The aquaculture industry is being pushed into deeper waters, to accommodate the increasing demand for seafood worldwide and the lack of nearshore sites: aquaculture systems for farther, harsher conditions are now being proposed. The Blue Growth initiative by the European Union is also tuned in the same direction, with the focus being on developing ocean based resources, including energy and aquaculture, and finding synergies among them. The present work proposes a novel multi-purpose platform (MPP), by retrofitting a feed barge with a small wind turbine and energy storage system, able to provide sustainable energy to a reference offshore aquaculture farm. The requirements and constraints for such hybrid system are defined, as well as a set of keys load cases, and its performance are analysed in the frequency domain. Wave loads are modelled using linear potential theory, while from an aerodynamic point of view, only the maximum thrust at the wind turbine hub level is considered in the static stability analysis. With reference to stability criteria and dynamic analysis in frequency domain, the suitability of the proposed MPP to act as a source of feed storage and energy supply is established, showing this as a potentially suitable solution.

Abstract:
In order to meet the sustainable development demand for energy, developing nuclear power actively has become an important means for the country to improve energy supply pattern and change the energy structure. The normal operation of the nuclear power station brings enormous economic and social benefits, but also accompanied by airborne radioactive effluent and liquid radioactive effluent discharge. In order to estimate the effect of radioactive effluent release during the normal operation of nuclear power plant on radiation dose of the environment and the public, in this article, domain knowledge analysis and domain knowledge modeling will be carried out on the theoretical model of evaluation calculation. Then, combined with actual business logic, advanced software development techniques and mature design ideas will be adopted to realize the field component of radiation dose evaluation in nuclear power plant. Establish the corresponding domain component library, and thus to achieve the building of radiation dose evaluation software system. The main content of this paper will be divided into two parts to elaborate, First part is the domain knowledge analysis and modeling of radiation dose evaluation model of nuclear power plant radiation environment, the other part is based on radiation dose evaluation component library software system researching, designing and achieving. In the domain knowledge analysis of the radiation dose estimation model, due to the mutual independence of the airborne radioactive effluent and the liquid radioactive effluent in the evaluation mode, this paper will analyze and model the domain knowledge separately. The airborne radioactive effluent is divided into four parts: air immersion external exposure, ground deposition external irradiation, ingestion inhalation and inhalation in air. The main contents of the analysis include atmospheric diffusion suitable for environmental characteristics of nuclear power plant site, ground deposition factors, food chain data, and lifestyle habits around the site. In the field of knowledge analysis of liquid radioactive effluent, there are four ways: external marine activity irradiation, coastal deposit sediment irradiation, and irradiation of seafood. The analysis mainly includes dilution and diffusion conditions in the surrounding sea area of nuclear power plant, the radionuclide in the seawater of the receiving water body, the shore sedimentation factor and the transfer model of the radionuclide in the seafood. Based on the detailed analysis and research on the radiation dose evaluation of nuclear power plant, and the designing of the domain model by adopting mature software design idea and the advanced software development technology, the domain component of the radiation dose evaluation field is realized, and build the corresponding domain component library. This can provide a reliable and usable domain component library for the radiation dose evaluation of each nuclear power plant, improve the maintainability of the radiation dose evaluation system of the nuclear power plant, the comprehensibility of business logic, and the reusability of the evaluate module, so as to meet the calculation demands on radiation dose effects of public caused by radionuclide release in normal operation of the nuclear power plant.

Abstract:
Over half of the seafood in the world today is produced through aquaculture. Many finfish species, such as Atlantic salmon, are farmed in permeable net pens in the ocean. Traditionally, these sites have been located in regions protected from high energy ocean swell, current, and wind. However, in areas such as Nova Scotia, Canada, there is a declining number of such protected locations available and so aquaculturists are moving into exposed sites. To safely operate at these sites, it is necessary to engineer the pens to withstand the forces of the open ocean. To conclusively assess finfish aquaculture equipment and moorings in open ocean conditions, Dynamic Systems Analysis Ltd. (DSA) has developed a finite-element net model (FENM) to interface with the dynamics simulation software ProteusDS. The following paper presents the development of the FENM and demonstrates the capability of the FENM to model wave and current loadings by comparing FENM simulations with published results from tank tests. In addition, the results of simulations of a full scale finfish aquaculture site in hurricane conditions are presented. The conditions were collected with an acoustic Doppler current profiler during hurricane Earl on September 4, 2010. The mooring line tensions from the ProteusDS simulation are compared against tensions measured during the storm with a Submersible Tension Logger (STL).

Abstract:
Finfish aquaculture has been expanding in areas like Norway and Canada over the last 20 years, and is projected to expand further in the next decades as the planet’s population and demand for seafood increases. Finding appropriate salmon farm sites is becoming increasingly difficult, as there are fewer protected nearshore locations available for development. As a result, there is interest in increased utilization of existing leases (i.e. permitted sites). These leases have a boundary in which the anchors and mooring lines must be contained. Reducing the footprint of the mooring arrangement will allow for an increased utilization of existing leases. A possible method to reduce the footprint of a spread moored salmon farm is to use a taut mooring rather than a chain catenary mooring. This requires the use of mooring materials and components that allows for handling of tidal elevation changes and wave action. This paper investigates the performance of a taut moored configuration with integrated Seaflex elastomeric mooring components in comparison with a conventional chain catenary configuration using dynamic analysis. The results show that a reduced footprint taut mooring configuration with integrated elastomeric mooring components can be substituted for a typical chain catenary mooring with no significant increase in peak mooring line loads at extreme sea states and significant reduction in peak loading at moderate and calm seastates.

Abstract:
The supply of healthy food is distributed unequally in city. The accessibility of healthy foods is affected by both locations and traffic conditions. This paper examines spatio-temporal disparities in healthy food accessibility in Shanghai communities. Firstly, we choose all communities in Shanghai and use python as a crawling tool to collect healthy food store POI (e.g. agricultural markets, vegetable markets, fruit markets, aquatic seafood markets, supermarkets and comprehensive markets) from Gaode Map and get 23,436 points to calculate the amount and density of healthy food store in various communities. Secondly, after comparing Baidu Map and Gaode Map, leading platforms of Web GIS services in China, we choose Baidu Map to collect data to study the spatio-temporal difference in accessibility by using network analysis and developing a crawling tool to collect different travel time (e.g. walking and public transportation) for each community to the closest healthy food store at each time of day (0:00-24:00). Thirdly, we set up a variable to see at what time are people in the communities able to reach their nearest healthy food store in 15 minutes and the ratio of the above-mentioned time to the whole day is calculated so that we can evaluate the temporal disparities of healthy food accessibility. Additionally, we use global and local spatial autocorrelation to analyze the spatial patterns of the temporal disparities of healthy food accessibility, based on the Moran’s index and the local indicator spatial association (LISA) index. Finally, on the basis of the research above, the food desert map is drawn. The results of this analysis identify the communities in Shanghai with the greatest need for improved access to healthy food stores and the variance of accessibility affected by the traffic in different times will be taken into account. Ultimately, this study explores a more complete and realistic condition of healthy food accessibility in Shanghai and the corresponding improvement strategy is proposed.

Abstract:
With the increasing world demand for seafood and environmental problems in coastal aquaculture, offshore area has been increasingly expected to be utilized for aquaculture. The present study proposed the concept of an offshore aquaculture system with an automated feeding platform. The offshore aquaculture system has fewer effects on the surrounding marine environment through the rapid diffusion of organic wastes than the coastal one. The offshore area then provides clean waters for cultured fish. On the other hand, the offshore aquaculture system is subject to the severe natural condition such as typhoon attack. Actually, in the current aquaculture system, the cultured fish is starved during a few days before and after typhoon attack since the feeding ship is not able to approach the offshore sea cages, which is submerged every time around 10m below the sea surface to escape from high waves and strong currents. The automated feeding system should be therefore developed to enable the cultured fish to grow faster under the severe natural condition. The proposed system consists of several submerged fish cages and a feeding platform, which includes fuel tanks, feed storage silos, and an automated feeding machine. The feeding platform was designed by numerical analysis and tank model test in order to suppress its motion as small as possible. The motion of the feeding platform was first predicted by numerical analysis. The unmoved point was formed at each period of the incident wave. It moves upward as the period of the incident wave increases. Consequently, the point at 8m below the sea surface (3m above the bottom of the feeding platform) is the best one to attach the feeding hose. As a result of tank model test, pitch and heave motions of the feeding platform were dominant in the waves with short (1.5 seconds) and long (3.1 seconds) periods, respectively. An unmoved point was observed on the surface of the feeding platform as predicted by the numerical model, while the top of the feeding platform moved more largely. The unmoved point for the feeding hose was specified at above the bottom of the feeding platform.

Abstract:
[Extract from Executive Summary] This project, aimed at the development of a novel, automated mechanism for the collection of scallop stock data was a sub-part of the Scottish Inshore Fisheries Integrated Data Systems (SIFIDS) project. The project reviewed the state-of-the-art remote sensing (geophysical and camera-based) technologies available from industry and compared these to inexpensive, off-the -shelf equipment. Sea trials were conducted on scallop dredge sites and also hand-dived scallop sites. Data was analysed manually, and tests conducted with automated processing methods. It was concluded that geophysical acoustic technologies cannot presently detect individual scallop but the remote sensing technologies can be used for broad scale habitat mapping of scallop harvest areas. Further, the techniques allow for monitoring these areas in terms of scallop dredging impact. Camera (video and still) imagery is effective for scallop count and provide data that compares favourably with diver-based ground truth information for recording scallop density. Deployment of cameras is possible through inexpensive drop-down camera frames which it is recommended be deployed on a wide area basis for further trials. In addition, implementation of a ‘citizen science’ approach to wide area recording is suggested to increase the stock assessment across the widest possible variety of seafloor types around Scotland. Armed with such data a full, statistical analysis could be completed and data used with automated processing routines for future long-term monitoring of stock.

Abstract:
R/V Alkor Cruise AL543 was planned as a six-day cruise with a program of water column and sediment sampling in Kiel Bight and the western Baltic Sea. Due to restrictions related to the Covid-19 pandemic, the original plan had to be changed and the cruise was realized as six oneday cruises with sampling in Kiel Bight exclusively. The first day was dedicated to water column and sediment sampling for radionuclide analyses at Boknis Eck and Mittelgrund in Eckernförde Bay. On the remaining five days, water column, bottom water, sediment and pore water samples were collected at eleven stations covering different types of seafloor environment (grain size, redox conditions) in western Kiel Bight. The data and samples obtained on cruise AL543 will be used to investigate (i) the sedimentary cycling of bio-essential metals (e.g., nickel, zinc, and their isotopes) as a function of variable redox conditions, (ii) the impact of submarine groundwater discharge and diffusive benthic fluxes on the distribution of radium and radon as well as greenhouse gases (methane and nitrous oxide) in the water column, and (iii) to characterize and quantify the impact of coastal erosion on sedimentary iron, phosphorus and rare earth element cycling in Kiel Bight.
