This thesis examines the readiness and perception in the regions of Gothenburg and Bremen towards future sea level rise. It does so through the theoretical lens of risk psychology / policy research and of climate science research. Results are built on some of the most recent research of these fields, as well as interviews with 14 people on the local, regional and national level in Germany and Sweden. Key findings of this thesis are that both contexts struggle to deal with the great uncertainties...

The ongoing changes in the extent and the properties of sea ice, associated with the warming climate, are affecting the polar ecosystem and the interactions between the atmosphere, sea ice and the underlying waters. How sea ice biogeochemistry will change in the foreseeable future is currently uncertain, but is a crucial problem to tackle.<p>To better understand how sea ice biogeochemistry could change, we investigated the factors regulating the distribution of some dissolved compounds (e.g. nut...

碩士 / 國立政治大學 / 亞太研究英語碩士學位學程(IMAS) / 104 / The primordial causal relationship within politics lies in the condition of our human nature, as classical realists argue. The constant exchange in power defines the relative relationships within the anarchical world, and shapes our pursuit of interests thereof. Such a change in power is occurring within China, and this is being reflected on its shifting policy and conduct in the South China Sea. Classical realism ought to shed light on and put forth a ne...

An autonomous underwater cable suspended dredging system is proposed with the application of combating the excess of nutrients in the Baltic Sea. The focus of the thesis is on modelling and designing of the control system used to guide an end-effector supplied with a pump along a predetermined path. The end-effector is guided with the help of four cables that are each controlled by a servomotor. The buoyancy of the end-effector in combination with the cables keeps the end-effector a few meter ab...

La synthèse protéique est une étape importante de la régulation de l'expression des gènes. Dans beaucoup d'espèces animales, les premières étapes du développement embryonnaire sont majoritairement ou exclusivement basées sur l'utilisation des messagers maternels stockés dans l'ovocyte. L'embryon d'oursin est un modèle avantageux pour l'étude du contrôle traductionnel de l'expression des gènes lors du développement précoce. La fécondation provoque l'activation de la machinerie traductionnelle con...

La jonction triple des Afars relie la mer Rouge, le golfe d'Aden et le rift éthiopien. Il est possible d'y étudier les différents stades d'extension depuis le rifting actif jusqu'aux marges continentales passives. Si l'extension et l'activité magmatique sont généralement considérées comme étant restreintes aux segments actifs des rifts ou aux dorsales océaniques, il existe pourtant une activité magmatique sur les flancs des marges continentales passives de l'Afar, du sud de la mer Rouge et du go...

Abstract Recent sea floor sulfide deposits form when seawater, heated within the oceanic crust, discharges to the sea floor. Upon mixing with cold seawater, sulfide-forming elements such as sulfur, iron, copper, and zinc are precipitated from the fluid. Actively forming sea floor massive sulfide deposits are found from different lithologic and tectonic environments varying from mid-ocean ridges to back-arc spreading centers. At a few localities, sulfide deposits are associated with turbiditic s...

Les mammifères marins de l'Océan Austral sont des éléments essentiels des écosystèmes marins antarctiques et des sentinelles de l’état des océans polaires. Comprendre comment les conditions océanographiques déterminent leurs habitats préférentiels est essentiel pour identifier de quelle façon et dans quelle région ces mammifères acquièrent les ressources nécessaires à leur déplacement, leur croissance, leur reproduction et donc leur survie. Les éléphants de mer du Sud (Mirounga leonina) se dépla...

Les communautés benthiques du bassin oriental de la Manche et du sud de la mer du Nord ont été abondamment documentées en termes de composition spécifique et de répartition spatiale. En revanche, les études portant sur leur fonctionnement n’ont été conduites que récemment dû à la difficulté d’obtention des différents paramètres biologiques des différents composants du benthos (bactérie, méiofaune, macrofaune…) indispensables à ce type d’analyses. L’objectif principal était de déterminer si la zo...

碩士 / 國立臺灣大學 / 海洋研究所 / 98 / Prokaryotic microbes are the largest population in oceans; they are evidently responsible for the major primary and secondary productions and, as a result, play a key role in significant element cycles in marine ecosystems and even global. However, the ecology, such as composition, distribution and diversity, of these microbes are still mainly unknown. To date, most of the studies of the marine prokaryotic community are only focused on the surface water or a certain de...

The current study focuses on the phenomenon, mostly accounted within the past recent time, of the algae blooms (chlorophyll burst) in the area of the North Aegean Sea. The study attempts to coincide and amplify the approach of Satellite Remote Sensing monitoring, as means of applied oceanographic methods, in order for possible seasonal, spatio-temporal trends of this phenomenon to be identified, thus making the correlation of the indices-variations, though interdisciplinary, to be explained to a...

The deep-sea has long been considered the last region one Earth to be untouched from anthropogenic disturbances. However, studies have shown that the deep-sea is not as pristine as once assumed and it has been suggested that it may actually act as a sink for persistent organic pollutants (POPs). POPs are ubiquitous in the environment and of particular concern due to their high persistence, toxicity, bioaccumulation potential and long-range transport. Although POPs have been detected in a range o...

The quantification and description of sea surface temperature (SST) is critically important because it can influence the distribution, migration, and invasion of marine species; furthermore, SSTs are expected to be affected by climate change. Recent research indicates that there has been a warming trend in ocean temperatures over the last 50 years. Hence, we sought to identify and demonstrate how a particularly germane SST dataset can be used within the scope of global climate change research. F...

Historically, it has been negative to be dependent on only one resource, in the current situation this resource represents oil. The oil dependence is primarily in the transport sector. From a Swedish perspective oil is an energy resource mainly used in the transport sector. Much of the oil that Sweden imports has its origin in the North Sea. The oil production in the North Sea has however begun to decline, which highlights that oil is a finite resource. This also means that Sweden has to start i...
