Aquatic sediments are, by surface, the largest habitat on Earth. A wide diversity of organisms inhabit these sediments and by their actions they have a large influence on and also mediate many ecosystem processes. Several of these processes, such as decomposition and remineralisation of organic matter are important on a global scale and are essential to sustain life on Earth. The main aim of this thesis was to use an experimental ecosystem ecology approach in order to study some of these ecosyst...

The Dublin Regulation determines the Member State responsible for accepting and making a decision on asylum claims lodged in the European Union (‘EU’), Norway and Iceland. It aims to ensure that each asylum claim is examined by one and only one Member State, to put an end to the practice of ‘asylum shopping’ and to prevent repeated applications, both of which have been costly for the receiving Member States and caused severe inefficiencies in the determination processes in the EU in the past.

Implementing oxygen isotopes (H218O, H216O) in coupled climate models provides both an important test of the individual model's hydrological cycle, and a powerful tool to mechanistically explore past climate changes while producing results directly comparable to isotope proxy records. The addition of oxygen isotopes in the University of Victoria Earth System Climate Model (UVic ESCM) is described. Equilibrium simulations are performed for preindustrial and Last Glacial Maximum (LGM) conditions...

Methane measurements over lake Tämnaren show a pronounced diurnal variation with high values at night and low values during daytime. The atmosphere over the lake and its surroundings is simulated with two different settings and resolutions of the WRF model during a period of eight days in May 2011 to investigate if a lake/land breeze circulation could be the cause of the observed methane variation. A night time land breeze can give rise to convergence over Tämnaren of the natural methane emissio...

The New Zealand (NZ) sea lion Phocarctos hookeri is the only pinniped endemic to NZ with a population of approximately 12,000 individuals. Its breeding range is currently restricted to NZ sub-Antarctic islands, and it has failed to recolonise its pristine distribution around the NZ main islands despite its protection since 1881. The current hypothesis is that the population growth of this pinniped is limited by the distribution of suitable prey on the Auckland Islands (50°30'S, 166°E) shelf, and...

As part of a health survey of New Zealand sea lions (Phocarctos hookeri) on Enderby Island, Auckland Islands (50°30’S, 166°17’E), neonatal mortality was continuously monitored at the Sandy Bay Beach rookery, from 1998/1999 to 2004/2005. The primary causes of death were categorised as trauma (35%), bacterial (24%) and hookworm (13%) infections, starvation (13%) and stillbirth (4%). During the 2001/2002 and 2002/2003 breeding seasons, bacterial epidemics caused by Klebsiella pneumoniae increased m...

The extent of Arctic sea ice has decreased over the years and the importance of sea ice monitoring is expected to increase. Remote sensing change detection compares images acquired over the same geographic area at different times in order to identify changes that might have occurred in the area of interest. Change detection methods have been developed for cryospheric topics. The Kittler-Illingworth thresholding algorithm has proven to be an effective change detection tool, but has not been used ...

Previously acquired seismic surveys provide strong evidence that the post-Last Glacial Maximum (LGM) retreat of the West Antarctic Ice Sheet (WAIS) deposited a back-stepping succession of seismically-resolved grounding zone wedges (GZWs) in eastern Ross Sea. However, the chronology of WAIS retreat is debated. The conventional view is that three GZWs (Red, Brown, and Gray Units) were deposited since the LGM. An alternative view, based on recent radiocarbon dates, is that the youngest GZW (the Gra...

Reproduction is a critical period of salmonid fish life history. As early life stages are particularly sensitive to biotic and abiotic constraints, studying these stages in terms of survival is essential in salmonid population ecology, stocks management, conservation and restoration. No characterization of salmonids spawning habitats on scientific basis has been made to date in Eastern Baltic region, which rivers are important for salmonid reproduction and significantly contribute to the sea tro...

The Pennell Coast continental shelf is isolated from West Antarctic Ice Sheet drainage; for an ice sheet to ground in this region it must flow over the Transantarctic Mountains from East Antarctica. Features observed indicate that ice grounded on the Pennell shelf. Cores from the shelf sampled till, a pelletized unit, glacial-marine sediments, contourite deposits, and diatomaceous muds. The timing of ice sheet grounding is revealed by radiocarbon dates that indicate the ice sheet was grounded on...

Ecological studies characterising population trends over decades or centuries can help to describe the range of variability in a study system, with well-studied species being strong candidates for providing the long-term data required for retrospective studies. Seabirds represent useful real-time monitors of marine systems and may also play this role in studies characterizing historical ecological change. The glaucous-winged gull L. glaucescens is a generalist marine bird occurring in the Salish...

This study explores two relevant questions in the realm of iron (Fe) bioavailability to phytoplankton. First, does Fe availability limit (or co-limit) growth of indigenous plankton communities in the Arctic Ocean? Second, can phytoplankton internalize ferrated siderophores with a non-reductive uptake mechanism? To address the first question, an 8-day grow out experiment was conducted in the Beaufort Sea in early September 2009, during which light, Fe, and nitrate (NO₃⁻) levels were manipulated. ...

The decline of Steller sea lions (Eumetopias jubatus) in the Gulf of Alaska appears to have been associated with a switch of diet from one dominated by fatty forage fishes (such as herring - Clupea pallasi) to one dominated by low fat fish (such as pollock - Theragra chalcogramma). Observations made during the decline include reduced body size of sea lions, low pregnancy rates, poor fur quality and high mortality. I used the general mammalian model, Rattus norvegicus, to test whether change...

Reduced availability of high energy-content prey (nutritional stress) is a predominant hypothesis to explain the decline of Steller sea lion (Eumetopias jubatus) populations in western Alaska from the late 1970'€™s to the late 1990'™s. Animals may physiologically respond to consuming insufficient prey by increasing stress levels and decreasing metabolic rates. It may thus be possible to identify nutritional stress by measuring concentrations of glucocorticoids (stress) and thyroid hormones (me...

Recent research using stable isotope analysis has shown a dependence on migrating or breeding populations of vertebrates as vectors for the transfer of marine-derived nutrients within coastal ecosystems. Sable Island, Nova Scotia, Canada supports numerous species of plants, a variety of seabird colonies (including common [Sterna hirundo] and Arctic [Sterna paradisaea] terns), the world’s largest grey seal (Halichoerus grypus) breeding colony, and a self-sustaining population of wild (feral) hors...

A model is formulated to study the influence of large coastline and shelf topography variations on the dynamics of stratified, low-frequency wind-driven frictional shelf waters. At low frequencies, currents nearly follow the isobaths. Therefore, the coordinate system should be a curvilinear system in which the coordinate lines are parallel and perpendicular to the isobaths. Writing the low frequency problem for stratified, frictional, time-dependent linear wind forced shelf flow in these coordin...

With ongoing sea level rise (SLR), tidal freshwater marshes (TFMs) eventually will be flooded with more brackish water. The impact of more water and salt on the plant community of TFMs, however, is unknown. With SLR, both the invasive reed Phragmites australis and the native salt marsh grass Spartina alterniflora could become dominant species in TFMs. I am looking at determining how increases in salinity and inundation caused by sea level rise will impact the relative distribution of Phragmite...
