This study focused on the management of the red sea urchin Loxechinus albus fishery in Chile. The main objective was to design, construct, implement and assess a computer-based simulation model to analyse the biological effects, socio-economic consequences and spatial dynamics resulting from coastal management plans applied to this resource under the system of AMEBR. This was accomplished by using systems dynamics (SD) and geographical information systems (GIS) modelling, in a process of model development, run, optimisation, sensitivity analysis and risk management, and a series of field-based activities carried out at the cove of Quintay. The GIS model developed for allocating sea urchins restocking sites offered a flexible, cost-effective, user-friendly and descriptive technique for support decision-making on management of this species and other benthic resources. Final site selection for restocking was based on the identification, quantification and selection of higher suitability¦availability combinations (site categories). This map showed 16 different suitability¦availability combinations or site categories, ranging from 4¦100 to 8¦100 (suitability points¦availability %). These had an average of 6.44¦69.37 (covering an area of 82.5 Ha overall equivalent to 81.21% of the study area. This site classification demonstrated high heterogeneity between options, and revealed the full variety of alternatives for decision-making. More importantly, the generally high suitability indexes as well as available area emphasised the prospects for restocking sea urchins in this study area. Over and above of the quantitative outcomes obtained from running the GISRM (suitable and available restocking sites) and the BSESM (alternative strategic management plans), the case study-based analysis made it possible to disclose the wider issues related to the red sea urchin coastal management. These results demonstrated the biological inefficiency of traditional size/seasonal restriction-based approach (macro-scenario 1) for sustainable management of the target species. More importantly, final outcomes strongly suggested that a combination of adaptive restocking-based enhancement activities and flexible exploitation constituted a highly attractive approach (macro-scenario 3) for stock management of this fishery in terms of harvestable stock and related incomes. However from the economic analysis, stocking was also found to be economically unfeasible, being a rather cost intensive exercise negatively affected by high natural mortality rates. A single-variable optimisation analysis demonstrated that a higher survival rate is needed to generate sufficient profits to cover major restocking costs and a positive payment, or a cost reduction is essential to make up for the loss. On top to these practical constraints, based on the distinctive modest economic situation prevailing for most Chilean coves and hence their limited capacity to pay for stocking material, unless adequate and constant funding is available to support artisanal associations, they are very unlikely to develop mass release programmes. Given the economic (i.e.: high operating costs) and technical (i.e.: low survival rates) limitations conditioning stocking-based management cost-effectiveness and applicability, wide implementation of mass releases as a major approach for management of the red sea urchin fishery is very unlikely to take place in Chile. This study presents a methodology and offers a tool to design, evaluate and optimise coastal management plans for the red sea urchin in a dynamic, interactive, systematic, integrated and flexible way. The optional strategic management plans proposed on this study may not be applied equally to any AMEBR, as they are the outputs arising from a single cove-specific analysis. Still, the complete methodological framework and analysis procedures developed may be applied to run the BSESM and optimise management of a red sea urchin fishery at any other AMEBR case of study.

Metagenomics has revealed that the marine microbial biosphere is immensely more diverse than originally considered, and is an almost untapped reservoir for the potential discovery of microbial natural products. Despite numerous advances in culturing, biosynthetic engineering and genomic-based screening efforts to uncover much of this diversity in relatively accessible environments, a high rediscovery rate has resulted in the investigation of unique, relatively unexplored ecosystems harboring phylogenetically diverse communities of marine organisms. The focus of this research was to establish a culture repository of microorganisms collected from the Red Sea and from deep-sea hydrothermal vents, and to assess their biosynthetic potential for the production of new chemical scaffolds. Cultivation of marine cyanobacteria from the Red Sea has led to the identification of five new cyclic depsipeptides, apratoxin H, grassypeptolides D and E, Ibu-epidemethoxylyngbyastin 3 and leptochelin, the latter possessing a unique chemical scaffold capable of binding metals. A collection of deep-sea hydrothermal vent sediment and microbial mat samples led to the isolation of 64 unique bacterial strains, with eight assigned as members of the order Actinomycetales. Importantly, these isolates, along with a collection of deep-vent invertebrates and microbes, have led to the development of methods for the collection, culturing and biological screening of organisms from this extreme environment for future natural products research. / Graduation date: 2013

The Red Sea region is one of the important places that allow us to uncover traces of the evolution of anatomically modern humans. Besides the questions related to its expansion out of Africa, this region is also important in terms of the mutual influence between populations of Africa and Arabia that after a long period of isolation and genetic differentiation related to climate change in the Pleistocene and subsequent development of seaways and land routes in the Holocene began to contact with each other more frequently. Number of genetic analyzes has been done but some issues concerning on the later development still remain inadequately answered, mainly because of insufficient material. This work is focused on the analysis of 200 mtDNA sequences of four Sudanese populations - two populations of nomadic herdsmen Rashaida and Beja living in the close neighborhood around the city of Kassala and speaking different languages and two populations of the Nile Valley with settled way of life. Analysis of the intrapopulation level revealed much higher diversity of the sedentary populations (in this work the sedentary populations are represented by the Nubians and Arabs). Interpopulation variability and genetic distances within other 46 populations of the Red Sea showed that although Rashaida and Beja people...

Global warming is affecting the Earth climate year by year, the biggest difference being observable in increasing temperatures in the World Ocean. Following the long- term global ocean warming trend, average sea surface temperatures across the global tropics and subtropics have increased by 0.4–1◦C in the last 40 years. These rates become even higher in semi-enclosed southern seas, such as the Red Sea, threaten- ing the survival of thermal-sensitive species. As average sea surface temperatures are projected to continue to rise, careful study of future developments of extreme temper- atures is paramount for the sustainability of marine ecosystem and biodiversity. In this thesis, we use Extreme-Value Theory to study sea surface temperature extremes from a gridded dataset comprising 16703 locations over the Red Sea. The data were provided by Operational SST and Sea Ice Analysis (OSTIA), a satellite-based data system designed for numerical weather prediction. After pre-processing the data to account for seasonality and global trends, we analyze the marginal distribution of ex- tremes, defined as observations exceeding a high spatially varying threshold, using the Generalized Pareto distribution. This model allows us to extrapolate beyond the ob- served data to compute the 100-year return levels over the entire Red Sea, confirming the increasing trend of extreme temperatures. To understand the dynamics govern- ing the dependence of extreme temperatures in the Red Sea, we propose a flexible local approach based on R-Pareto processes, which extend the univariate Generalized Pareto distribution to the spatial setting. Assuming that the sea surface temperature varies smoothly over space, we perform inference based on the gradient score method over small regional neighborhoods, in which the data are assumed to be stationary in space. This approach allows us to capture spatial non-stationarity, and to reduce the overall computational cost by taking advantage of distributed computing resources. Our results reveal an interesting extremal spatial dependence structure: in particular, from our estimated model, we conclude that significant extremal dependence prevails for distances up to about 2500 km, which roughly corresponds to the Red Sea length.

Tsunami concerns have increased in the world after the 2004 Indian Ocean tsunami and the 2011 Tohoku tsunami. Consequently, tsunami models have been developed rapidly in the last few years. One of the advanced tsunami models is the GeoClaw tsunami model introduced by LeVeque (2011). This model is adaptive and consistent. Because of different sources of uncertainties in the model, observations are needed to improve model prediction through a data assimilation framework. Model inputs are earthquake parameters and topography. This thesis introduces a real-time tsunami forecasting method that combines tsunami model with observations using a hybrid ensemble Kalman filter and ensemble Kalman smoother. The filter is used for state prediction while the smoother operates smoothing to estimate the earthquake parameters. This method reduces the error produced by uncertain inputs. In addition, state-parameter EnKF is implemented to estimate earthquake parameters. Although number of observations is small, estimated parameters generates a better tsunami prediction than the model. Methods and results of prediction experiments in the Red Sea are presented and the prospect of developing an operational tsunami prediction system in the Red Sea is discussed.

The main purpose of this research is to investigate Jordan and Israel's participation in the Red Sea – Dead Sea Water Convenience project from human security point of view. The Red Sea – Dead Sea Water Conveyance project is planned to desalinate water from Red Sea to the Dead Sea and provide fresh water to Jordan, Israel and possibly Palestine. I use a human security approach in this investigation because it has a broader people-centered security perspective. This approach guides the research to consider water related issues and challenges in Jordan and Israel to which the project can be a possible solution. I use qualitative content analysis to investigate the issues identified by Jordan and Israel, and how the project is estimated to address these challenges. I argue that the estimated benefits that the implementation of the project provides for human well-being in Jordan and Israel makes them to participate in this project.

This paper concerns the planning for sustainable development of a global common pool resource within an autocratic region. The study is focused on the coral reef of the Red Sea, shared between the basin countries; Djibouti, Egypt, Saudi Arabia, Sudan, Yemen, Somalia, Israel, Jordan and Eritrea, where most nations are autocracies and developing countries. The viewpoint of this research is the only multinational project within the region focused on the conservation and sustainability of the coral reefs in the Red Sea, the “Regional Action Plan for the Conservation of Coral Reefs in the Red Sea and Gulf of Aden (RAP CCRRSGA)”. The aim of the research in this paper is to study the planning of this project in relation to sustainable development, through an interpretation of Ostrom’s framework using seven out of eight design principles. This research is executed through a method of ideal-type analysis, in order to assess how ideal-types of these design principles correlate with the planning of this project through similarities between the project and the design principles. This research has resulted in and demonstrated the importance of clarified compliance and cooperation, to reach effective and successful planning of sustainable development pertaining to a shared common pool resource within an autocratic region.

This thesis highlights the role of urban planners in the revitalization of historic seafronts as creative and attractive places for people and a key factor in the regeneration of the urban economy in the historic seafront areas. The Saudi Arabia historic seafront areas along the North Red Sea have been neglected and are suffering because of slow development and changes to industrial uses. This thesis will focus on the urban design principles that make historic seafronts more attractive and successful, and will use a case study approach of several American waterfront cities such as Baltimore, Maryland; San Francisco, California; and Charleston, South Carolina. These American cities and the urban design principles applied for their successful revitalization were selected for analysis because of their similarities with the Yanbu Al-Bahr's historic seafront. The results of this analysis will enable planners to apply the best of these urban waterfront design models to assist in the revitalization of historic seafronts along the North Red Sea in the Kingdom of Saudi Arabia (KSA).

Le but de la thèse est d’analyser l’importance idéologique et religieuse des expéditions égyptiennes au pays de Pount, particulièrement sous la XVIIIe dynastie. La 1ère partie (chapitres 1-4) présente en détail les sources relatives aux expéditions pountites et des produits en rapportés. Bien que la prééminence soit réservée aux sources de la XVIIIe dynastie, les documents datant d’autres périodes ont été aussi inclus dans les analyses. La 2e partie (chapitres 5-8) constitue une synthèse des conclusions formulées en résultat des analyses faites dans la 1ère partie. De cette façon, l’auteur examine les divers toponymes relatifs au pays de Pount (chapitre 5), le problème de la localisation exacte de Pount (chapitre 6), le caractère des expéditions pountites en comparaison aux autres types des missions étrangères égyptiennes (chapitre 7) aussi bien que les divers liens entre le pays de Pount et la religion et l’idéologie du pouvoir en Égypte (chapitre 8). L’auteur conclut que Pount jouait un rôle crucial dans l’idéologie du pouvoir égyptienne étant particulièrement associé au dieu solaire aussi bien qu’à la déesse Hathor. Les produits pountites étaient extrêmement importants tant pour le culte funéraire royal et privé que pour le culte divin rendu dans les temples. C’est pourquoi l’organisation d’une expédition pountite était un devoir du roi qui, selon les croyances égyptiennes, obéissait à un ordre direct du dieu solaire. En plus, aux diverses époques on peut percevoir une volonté de rétablir les contacts avec Pount afin de restaurer l’ordre naturel après une période de la crise, ce qui est particulièrement visible sous le règne d’Hatchepsout de la XVIIIe dynastie. / The aim of the dissertation is to analyse the religious and ideological significance of the ancient Egyptian Punt expeditions, particularly in the 18th dynasty. In the first part (chapters 1-4) the sources concerning the ancient Egyptian Punt expeditions as well as the products imported to Egypt in their result were discussed in detail. Although the pre-eminence is given to the 18th dynasty sources, documents from other periods were also included in the analysis. The second part (chapters 5-8) constitutes a synthesis of the conclusions drawn in result of the analysis of the sources of the first part. Therefore, the author discusses various toponyms related to the land of Punt (chapter 5), the problem of Punt’s exact location (chapter 6), the character of the Punt expeditions in comparison with other foreign missions (chapter 7) as well as various links between the land of Punt and Egyptian religion and ideology of kingship (chapter 8). The author concludes that the land of Punt played an important role in the Egyptian ideology of kingship being especially associated with the sun-god as well as with the goddess Hathor. Puntite products were crucial for both royal and private funerary cult as well as for the divine cult carried out in the temples. This is why the organisation of a Punt expedition was a duty of the Egyptian king, who, according to Egyptian beliefs, was obeying a direct order of the sun-god. Moreover, in various periods we may observe a wish to re-establish the contacts with Punt in order to restore the natural order of things after a period of crisis, which is especially visible in the reign of Hatshepsut of the 18th dynasty.
