Abstract:
ABSTRACT. This paper addresses the characterization of the geomorphology and palaeo-evolution of the La Plata River on the south Brazilian continental shelf,through bathymetric data and sedimentary and palynological analysis from sediment core samples. The analysis allowed us to characterize a transgressive depositionalsequence in the La Plata River palaeo-channel. The palynological sequences revealed continental fresh water environments, that involved into lagoonal and mixohalineenvironments and then into shallow marine environments towards the top, thus characterizing a fluvial-estuarine environment. These new data offer sufficient informationto establish the palaeo-geographic evolution of the La Plata River palaeo-channel and its local influence on the sedimentation of the Rio Grande do Sul Statecontinental shelf.Keywords: palaeo-valley, continental shelf, marine transgression, La Plata River. RESUMO.

Abstract:
Abstract. Data assimilation (DA) is an emerging topic in palaeoclimatology and one of the key challenges in this field. Assimilating proxy-based continental mean temperature reconstructions into the MPI-ESM model showed a lack of information propagation to small spatial scales . Here, we investigate whether this lack of regional skill is due to the methodology or to errors in the assimilated reconstructions. Error separation is fundamental, as it can lead to improvements in DA methods. We address the question by performing a new set of simulations, using two different sets of target data; the proxy-based PAGES 2K reconstructions (DA-P scheme), and the HadCRUT3v instrumental observations (DA-I scheme). Again, we employ ensemble-member selection DA using the MPI-ESM model, and assimilate Northern Hemisphere (NH) continental mean temperatures; the simulated period is 1850–1949 AD. Both DA schemes follow the large-scale target and observed climate variations well, but the assimilation of instrumental data improves the performance. This improvement cannot be seen for Asia, where the limited instrumental coverage leads to errors in the target data and low skill for the DA-I scheme. No skill on small spatial scales is found for either of the two DA schemes, demonstrating that errors in the assimilated data are not the main reason for the unrealistic representation of the regional temperature variability in Europe and the NH. It can thus be concluded that assimilating continental mean temperatures is not ideal for providing skill on small spatial scales.

Abstract. Energy exchanges among climate subsystems are of critical importance to determine the climate sensitivity of the Earth's system to greenhouse gases, to quantify the magnitude and evolution of the Earth's energy imbalance, and to project the evolution of future climate. Thus, ascertaining the magnitude of and change in the Earth's energy partition within climate subsystems has become urgent in recent years. Here, we provide new global estimates of changes in ground surface temperature, ground surface heat flux, and continental heat storage derived from geothermal data using an expanded database and new techniques. Results reveal markedly higher changes in ground heat flux and heat storage within the continental subsurface than previously reported, with land temperature changes of 1 K and continental heat gains of around 12 ZJ during the last part of the 20th century relative to preindustrial times. Half of the heat gain by the continental subsurface since 1960 has occurred in the last 20 years.

Abstract:
Crustal thickness is a critical parameter for understanding the processes of continental rifting and breakup and the evolution of petroleum systems within passive margins. However, direct measurements of crustal thickness are sparse and expensive, highlighting the need for methodologies using gravity anomaly data, jointly with other geophysical data, to estimate crustal thickness. We evaluated alternative gravity inversion methodologies to map crustal thickness variations at rifted continental margins and adjacent oceanic basins, and we tested our methodology in the South China Sea (SCS). Different strategies were investigated to estimate and remove the gravity effect of density variations of sediments and the temperature and pressure variations of the lithospheric mantle from the observed free air gravity anomaly data. Sediment density was calculated using a relationship between sediment thickness, porosity, and density. We found that this method is essential for crustal thickness inversion in the presence of a thick sedimentary cover by comparing the Moho depths obtained from gravity inversion and seismic interpretation in the Yinggehai Basin where sediments are up to 13 km thick; the inversion accuracy depended on the parameters of the exponential equation between porosity and the buried depth. We modeled the lithospheric mantle temperature field based on oceanic crustal age, continental crustal stretching factors, and other boundary conditions. We tested three different methods to calculate the thermal expansion coefficient, which is either held constant or is a linear/polynomial function of temperature, for applying a thermal correction and found that the inversion results were relatively insensitive to alternative methods. We compared inversion results with two recent deep seismic profiles that image the rifted continental edge at the northern margin of the SCS and the continental Liyue Bank (Reed Bank) at the southern margin, and we found that the inversion accuracy was improved considerably by removing sediment, thermal, and pressure gravity effects.

Abstract:
L'objectiu d'aquesta tesi és implementar un sistema d'assimilació de dades a un model hidrodinàmic de la plataforma continental catalana. Aquest sistema ens permetrà combinar la informació proporcionada per les dades mesurades amb la informació que prové dels models numèrics per tal de fer la millor estimació possible, en termes estadístics, de la realitat.<br/>Per arribar a aquesta fita cal en un primer moment tenir un bon coneixement de la regió d'estudi i els processos físics que hi tenen lloc. La següent passa és disposar de un model numèric que sigui capaç de reproduir de manera realista la dinàmica de la zona.<br/>Acte seguit cal identificar i caracteritzar les fonts d'errors del sistema i la seva dinàmica per, finalment, poder implementar un sistema d'assimilació de dades adequat al problema que tracta. Seguint aquest camí podem aprofitar les dades i les eines desenvolupades per aprofundir en el coneixement de la dinàmica a la plataforma continental catalana des de diversos plantejaments.<br/>- L'estudi de les mesures obtingudes en el marc dels projectes FANS i YOYO ens ha permès caracteritzar la dinàmica de la regió, estudiar l'origen de la variabilitat del corrent de tal·lus tant per altes com per baixes freqüències, estudiar els processos sobre la plataforma i veure l'evolució de les masses d'aigua.<br/>-La implementació del model hidrodinàmic SYMPHONIE s'ha fet amb cura aplicant una novedosa tècnica d'inicialització i s'ha validat amb dades reals per tal d'obtenir un model complet i realista. Un pic aconseguit això l'hem emprat per estudiar l'evolució d'una ona topogràfica de Rossby sobre la plataforma continental, l'efecte del vent en la dinàmica tridimensional i els intercanvis plataforma-tal.lús induïts pel vent i per oscil·lacions del corrent de tal.lús.<br/>-L'ús de la modelització estocàstica ens ha permès descriure la dinàmica dels errors associats a la caracterització del corrent de tal·lus i al camp de vents podent veure que els primers són no lineals però estacionaris mentre que els segons són lineals però no estacionaris. A partir d'aquests resultats també hem definit la base d'EOFs que defineix l'espai d'ordre reduït on es farà l'assimilació de dades.<br/>-Aprofitant els elements mencionats abans hem implementat el sistema d'assimilació de dades SEQUOIA amb un nucli d'anàlisi basat en interpolació òptima d'ordre reduït. <br/>Després d'avaluar el seu comportament hem utilitzat un protocol d'experiències bessones per comparar l'efectivitat de diverses xarxes de mesura per corregir diversos errors del model.<br/>Malgrat tot el treball s'ha centrat a la plataforma continental catalana gran part dels resultats obtinguts i de les tècniques emprades són aplicables a qualsevol altra regió amb característiques similars.<br>The goal of this thesis is to implement a data assimilation scheme into a hydrodynamic model of the Catalan continental shelf. This system would allow us to combine the information provided by measured data with the information coming from the numerical models in order to find the best approach, from a statistical point of view, of reality.<br/>To reach this objective it is needed, in a first moment, to have a good knowledge of the region and of the physical processes therein. The next step is to have a numerical model able to reproduce in a realistic way the dynamics of the area. Afterwards, the error sources of the system and the error dynamics should be characterized to, finally, implement a data assimilation system well suited for the problem. <br/>Following this way we can take profit of the data available and the tools developed to deepen in the the knowledge of the dynamics in the Catalan continental shelf from different approaches.<br/>-The analysis of the measures obtained in the frame of the research projects FANS and YOYO have allowed us to characterize the region dynamics, to study the origin of the slope current variability in the high and low frequencies, to study the processes over the shelf and to see the water mass evolution.<br/>-The implementation of the hydro dynamical model SYMPHONIE has been done carefully applying a new initialization technique (the modal potential vorticity method) and has been validated again real data to obtain a complete and realistic model. Once we had this part done, we have used it to study the evolution of a topographic Rossby wave over the continental shelf, the wind effects over the 3D dynamics and the exchanges shelf-slope induced by the wind and the slope current.<br/>-The stochastic modelling has been used to describe the dynamics of the errors associated to the slope current characterization and the wind field. We have determined that the former are stationary but non linear while the last are non stationary but highly linear. From these results we have also defined the EOFs base which defines the reduced order space where the data assimilation will be carried on. <br/>-Taking profit of the above mentioned elements, we have implemented the SEQUOIA data assimilation system with an analysis kernel based in the reduced order optimal interpolation. After evaluation its behaviour we have used a twin experiments protocol to compare the performance of different observational networks to correct different model errors.<br/>Although all the work have been done in the frame of the Catalan continental shelf, most of the obtained results and the techniques used could be applied to other shelf-slope regions with similar characteristics.

Abstract:
This dissertation is devoted to seismic tomography. I have implemented a new modelling tool for 3-D joint refraction and reflection travel-time tomography of wide-angle seismic data (TOMO3D). The reason behind this central objective is the evidence that the information based on 2-D seismic data does not allow to capture the structural complexity of many 3-D targets, and in particular that of the seismogenic zone in subduction margins. The scientific rationale for this statement, which justifies the central part of my thesis work, is based on the analysis of 2-D models obtained in the convergent margin of Nicaragua, a seismically active area where a textbook example of tsunami earthquake took place in 1992. In this application I modelled two perpendicular wide-angle seismic profiles for the characterisation of the overriding plate and the interplate fault. To do this, I applied TOMO2D, a state-of-the-art joint refraction and reflection 2-D travel-time tomography code. The inversion outcomes are two 2-D velocity models along both profiles, together with the 1-D geometry of the interplate boundary. In combination with other geophysical data measurements, namely coincident multichannel seismic profiles and gravity data, these models provide new constraints on the nature and structure of the margin, and in particular add new insights on the nucleation and propagation of the said earthquake and its tsunamigenic behaviour. Ultimately, this case study evidences the aforementioned limitations of 2-D modelling in the investigation of 3-D geological structures and phenomena. Following from this first application and with the idea of increasing the amount of data used in travel-time tomography, I focused on an a priori paradoxical phenomenon related to water-layer multiple phases, that under certain circumstances, is observed on wide-angle record sections. The interest of this study lies in the fact that this phenomenon can provide additional constraints on travel-time tomography models. First, I propose and corroborate the hypothesis explaining the apparent paradox, and then derive the most favourable geological conditions for the phenomenon to occur. Subsequently, the possibility to model this multiple-like phases is introduced in TOMO3D. The development of TOMO3D, which constitutes the core of my work, is founded on TOMO2D, from which it inherits the numerical methods for solving the forward and inverse problems. Source files have been rewritten, redefining and introducing the necessary variables and functions to handle 3-D data inversion. The tests made with the sequential version of the code emphasise the need of parallelisation for practicality reasons. Indeed, the increasing size of data sets along with the modelling of the additional spatial dimension results in computationally demanding inversions. Hence, I parallelised the forward modelling part of the code, which takes up to 90% of the computing time, with a combination of multiprocessing and message-passing interface extensions. Subsequently, the parallel version of TOMO3D is applied to a complex synthetic case simulating a subduction zone. This first 3-D application serves to evaluate the correctness of the code's programming, and as step-by-step description of the modelling procedure, with particular attention on the layer-stripping strategy used to successively model several reflectors. The outcomes demonstrate the ability of the code and the chosen inversion strategy to accurately recover the velocity distribution and the geometry of the two reflectors. Finally, TOMO3D is applied to a real 3-D wide-angle seismic data set acquired at the Pacific margin of Ecuador and Colombia to extract a 3-D velocity model of the overriding and incoming plates, which is then compared to previous results obtained with an extensively tested and used 3-D refraction travel-time tomography code (FAST). The comparison indicates that TOMO3D is more accurate than FAST but at the same time it is computationally more demanding. However, the parallelisation of TOMO3D allows using high-performance computing facilities, which is not the case of FAST or most of the existing codes.<br>Aquesta tesi està dedicada a la tomografia sísmica. Concretament, he implementat una eina de modelització 3D per a la tomografia conjunta de temps de trajecte de refraccions i reflexions (TOMO3D). La raó darrere d'aquest objectiu és l'evidència de que la informació basada en dades sísmiques 2D no permet copsar la complexitat de gran part dels cossos geològics, i en particular de la zona sismogènica en marges de subducció. El desenvolupament del TOMO3D es basa en el TOMO2D, un codi d'avantguarda per a la tomografia conjunta de refraccions i reflexions en 2D. Els arxius de codi han estat reescrits, redefinint i introduint les funcions necessàries per dur a terme la inversió 3D. Els testos fets amb la versió seqüencial del codi posen de manifest la necessitat de paral·lelització ja que l'increment de la mida dels conjunts de dades així com la modelització de la dimensió espacial afegida fan que les inversions siguin computacionalment exigents. La versió paral·lelitzada del TOMO3D ha sigut aplicada a un cas sintètic complex que simula una zona de subducció. Aquesta primera aplicació 3D serveix per avaluar la correcció de la programació del codi, i com a descripció pas a pas del procediment de modelització. Els resultats demostren la capacitat del codi per recuperar acuradament la distribució de velocitat i la geometria dels dos reflectors. Finalment, el TOMO3D és aplicat a un conjunt 3D de dades de sísmica de gran angle adquirit al marge pacífic d'Equador i Colòmbia per extreure'n un model 3D de la velocitat de les plaques cavalcant i subduïda, que és comparat amb el resultat obtingut amb un codi 3D de tomografia de temps de trajecte de refraccions (FAST). La comparació indica que el TOMO3D és més acurat que el FAST però al mateix temps és computacionalment més exigent. Tot i així, la paral·lelització del TOMO3D permet utilitzar plataformes de supercomputació, a diferència del que passa amb el FAST i la majoria de codis existents.

Mestrado em Engenharia Geológica<br>Dados de batimetria multifeixe e de sísmica de alta resolução, adquiridos na plataforma continental da Antártida, região Este, permitiram o reconhecimento de aspetos geomorfológicos derivados da dinâmica glaciar associada a um manto de gelo mais extenso no passado. No âmbito do projeto científico Norte-americano, Vulnerability of East Antarctic ice shelves da NSF (National Science Foundation), e do projeto EAIS-MARGINS do Programa Polar português (PROPOLAR), foi realizada a interpretação e análise quantitativa dos diversos aspetos morfológicos através da morfometria e análise estatística, com o objetivo de melhor entender a dinâmica do manto de gelo no passado. A área de estudo inclui um segmento da plataforma continental compreendida entre os glaciares Frost e Dibble (128ºE e 134ºE). Os dados foram adquiridos na campanha de investigação NBP1503 em Abril de 2015, a bordo do navio RVIB Nathaniel B. Palmer dos Estados Unidos da América. Os resultados revelam uma plataforma continental situada entre os 300 e 990 m de profundidade. A zona proximal e intermédia é caracterizada por um aspeto irregular, onde é possível constatar a presença de meltwater channels com mais de 230 m de profundidade e formas semelhantes a drumlins, identificadas entre os 800 e 900 m de profundidade. Sulcos deixados pela deriva de icebergs são esporadicamente observados na zona distal da plataforma continental entre os 380-410 m de profundidade. No limite da plataforma continental encontra-se presente um sistema de gullies que se desenvolvem ao longo do talude. Além disso a análise quantitativa dos aspetos morfológicos associados às formas de drumlin e gullies permitiu uma descrição morfológica mais detalhada, e encontrar padrões que permitiram obter mais informações sobre os fatores de controlo envolvidos durante a sua formação. A distribuição observada das diferentes morfologias identificadas é coerente com estudos anteriormente realizados e constituem uma forte evidência de que o manto de gelo teve uma extensão até ao limite da plataforma continental e que a sua dinâmica foi mais ativa do que se tem constatado.<br>Swath bathymetric and sub-bottom CHIRP data collected on the East Antarctica continental shelf and seaward allowed detailed mapping of the geomorphic features formed during past times of extended grounded ice from an expanded East Antarctic Ice Sheet (EAIS). Under the umbrella of the American National Science Project 'Vulnerability of East Antarctic ice shelves' and the Portuguese PROPOLAR project EAST-MARGINS, the seafloor morphology was interpreted and submitted to quantitative analyses, through morphometry and statistical analysis, to better understand the EAIS dynamic in the past. The study area included a segment of the continental shelf, slope and rise between the Frost and Dibble Glaciers (128ºE and 134ºE). The data were collected during the cruise NBP1503 in April 2015, on board the U.S. RVIB Nathaniel B. Palmer. The results revealed a continental shelf with depths varying between 300 m and 990 m. The inner and mid shelf area is characterised by a crudely streamlined landscape where subglacial meltwater channels up to 230 m deep and drumlin-like bedforms at 800-900 m water depth have been identified. Sporadic iceberg scours occur in the outer continental shelf between 380-410 m of water depth. The shelf break is defined by a gully system which extends along the continental slope, followed by sediment mounds observed on the continental rise. Moreover, quantitative analyses on drumlin-like bedforms and gullies allowed a further morphological description to better delineate patterns, and provided more details related to the controlling factors involved during their formation. The distribution of identified glacial features is coherent with other previous studies and constitutes a strong evidence that the grounded ice reached the continental shelf break in the past and was more dynamic than previously thought.

Abstract:
Land cover is a reliable source for studying changes in the land use patterns at a large scale. With advent of satellite images and remote sensing technologies, land cover classification has become easier and more reliable. In contrast to the conventional land cover classification methods that make use of land and aerial photography, this research uses small scale Digital Elevation Maps and it’s corresponding land cover image obtained from Google Earth Engine. Two machine learning techniques, Boosted Regression Trees and Image Analogy, have been used for classification of land cover regions in continental United States. The topographical features selected for this study include slope, aspect, elevation and topographical index (TI). We assess the efficiency of machine learning techniques in land cover classification using satellite data to establish the topographic-land cover relation. The thesis establishes the topographic-land cover relation, which is crucial for conservation planning, and habitat or species management. The main contribution of the research is its demonstration of the dominance of various topographical attributes and the ability of the techniques used to predict land cover over large regions and to reproduce land cover maps in high resolution. In comparison to traditional remote sensing methods such as, aerial photography, to develop land cover maps, both the methods presented are inexpensive, faster. The need for this research is in synergy with past studies, which show that large-scale data, processing, along with integration and interpretation make automated and accurate methods of change in land cover mapping highly desirable.

Abstract:
AbstractThis chapter seeks to address the concerns associated with data regulation on the African continent. In particular, the paper zooms in on three major aspects of data regulation that hold the reigns to the potential development of the continent. These are the free flow of data, the adoption of open data regimes and cybersecurity. This will be in the general context of Africa, with a focus on regulatory instruments from the different bodies at continental and sub-regional level as well as some national legislation from countries that have developed any legislative instruments that address the same concerns. Emphasis will also be paid to the strides that have been taken by the European Union, the first continental body that has taken a geographically concerted approach to comprehensive data regulation. The aim is to draw lessons from such efforts with the intention of determining an appropriate African centred approach to data regulation, particularly in the context of increased inter-African trade as envisaged by the Agreement on the African Free Continental Trade Area and an enhanced digital economy as motivated for in the Digital Transformation Strategy for Africa (2020–2030).

Abstract:
Abstract Pipeline operators are today faced with an increasing number of challenges. In addition to implementing more rigorous pipeline integrity programs, integration of pipeline data has now become a major concern. Through the use of a highly accurate inertial navigation system (INS) on board an In Line Inspection (ILI) smart pig, longitude, latitude and elevation coordinates can now be provided along the pipeline every tenth of an inch. This information provides the most accurate reference for integrating and relating pipeline data in a comprehensive manner. One of the most significant benefits to the operator is an absolute reference for integration of legacy and current pipeline data. This paper describes the processes involved in providing a data integration service to a major pipeline operator in the continental United States. Additionally, this paper shall focus on the benefits of combining pipeline-mapping services with an ILI smart pig survey.

Full text
Abstract:
Abstract Field testing has been carried out on the Norwegian Continental Shelf (Tromsøflaket and Troll field) at depths down to 500 meters, utilizing automatic logging units for in-situ monitoring of cathodic protection and environmental data. The main objective was to establish design data for cathodic protection of future installations in these areas and at large water depths. Very high design current densities were necessary to achieve rapid and efficient cathodic polarization at Tromsøflaket and Troll. The polarization behaviour of steel cathodes and galvanic anodes has been related to sea water environmental parameters, CP design and the characteristics of the calcareous layers formed. The results illustrate that a high design initial current density promotes the formation of dense calcareous layers, thereby reducing the long-term current consumption for maintenance of cathodic protection. Once such layers have formed, variations in sea water flow had very little effect on the cathodic current density. No incidences of cathodic depolarization related to erosion or spalling of calcareous layers were registered.

Abstract:
ABSTRACT As part of an ongoing exploration effort, approximately 4000 line-km of seismic data have recently been acquired and interpreted within the Comoros Exclusive Economic Zone (EEZ). Magnetic and gravity values were recorded along the seismic lines and have been integrated with pre-existing regional data. The combined data sets provide new constraints on the nature of the crust beneath the West Somali Basin (WSB), which was created when Africa broke away from Gondwanaland and began to move north. Despite the absence of clear sea-floor spreading magnetic anomalies or gravity anomalies defining a fracture zone pattern, the crust beneath the WSB has been generally assumed to be oceanic, based largely on regional reconstructions. However, inappropriate use of regional magnetic data has led to conclusions being drawn that are not supported by evidence. The identification of the exact location of the continent-ocean boundary (COB) is less simple than would at first sight appear and, in particular, recent studies have cast doubt on a direct correlation between the COB and the Davie Fracture Zone (DFZ). The new high-quality reflection seismic data have imaged fault patterns east of the DFZ more consistent with extended continental crust, and the accompanying gravity and magnetic surveys have shown that the crust in this area is considerably thicker than normal oceanic and that linear magnetic anomalies typical of sea-floor spreading are absent. Rifting in the basin was probably initiated in Karoo times but the generation of new oceanic crust may have been delayed until about 154 Ma, when there was a switch in extension direction from NW-SE to N-S. From then until about 120 Ma relative movement between Africa and Madagascar was accommodated by extension in the West Somali and Mozambique basins and transform motion along the DFZ that linked them. A new understanding of the WSB can be achieved by taking note of newly-emerging concepts and new data from adjacent areas. The better-studied Mozambique Basin, where comprehensive recent surveys have revealed an unexpectedly complex spreading history, may provide important analogues for some stages in WSB evolution. At the same time the importance of wide continent-ocean transition zones marked by the presence of hyper-extended continental crust has become widely recognised. We make use of these new insights in explaining the anomalous results from the southern WSB and in assessing the prospectivity of the Comoros EEZ.

Abstract:
The African Continental Free Trade Area (AfCFTA) is the largest free trade agreement in the world by number of members and geographical area covered. It spans 54 African countries, 2 with a combined gross domestic product (GDP) of US$3.5 trillion and 1 billion consumers. Although initial trading under the agreement officially commenced in 2021, there are still ongoing negotiations on several outstanding protocols. This issue of Trade Hot Topics provides an overviewof the ongoing debate regarding cross-border data flows and their restriction. It examines this debate in light of Africa’s digital needs and explores how cross-border data flows are regulated in the multilateral trading system and other large regional trade agreements, as well as by different African countries. It concludes with some recommendations for the negotiations on the AfCFTA Digital Trade Protocol.
