β-N-methylamino-L-alanine (BMAA) is one of the more recently discovered bioactive compounds produced by cyanobacteria. BMAA is a non-protein amino acid reported present in human brain tissues of patients deceased from a neurodegenerative disease, such as Alzheimer´s disease or amyotrophic lateral sclerosis (ALS). This observation in combination with its neurotoxic effects in eukaryotes (in vivo and in vitro) and its potential to incorporate into (human) proteins, causing protein aggregation, sug...

Underwater video data are a rich source of information for marine biologists. However, the large amount of recorded video creates a ’big data’ problem, which emphasizes the need for automated detection techniques. This work focuses on the detection of quasi-stationary crabs of various sizes in deep-sea images. Specific issues related to image quality such as low contrast and non-uniform lighting are addressed by the pre-processing step. The segmentation step is based on color, size and sha...

The role that signaling molecules play during morphogenesis and their interactions is a field of intense study and the sea urchin represents a facile system to study these aspects of development in the early embryo. In many instances, the S. purpuratus genome contains relatively simple receptor-ligand signaling systems compared to vertebrate counterparts and this provides interesting opportunities to study their diversity of function during the morphogenetic events that shape the embryo. The Eph...

My dissertation traces how the interplay of trafficking and regulation shaped free trade in the Arabian Sea. It explores trafficking in the littoral region stretching from western India to the Swahili Coast, as it evolved under colonial regulation. British officials wanted commercial practices in the Arabian Sea to conform to their perception of free trade, but their dedication to laissez-faire policies prevented them from intervening directly in trade. But smuggling provided the perfect just...

Disagreements concerning pycnogonid relations to other arthropods, including homologous characters, is partly a product of too few primary observations of pycnogonid anatomy and development. This investigation of post-embryonic development of the pycnogonid Anoplodactylus eroticus employs multiple techniques of anatomical observation in order to thoroughly document the life cycle. Morphogenesis is described as a series of stages identified by examination of live, freshly collected specimens und...

Earlier studies indicate that the interaction between heterotrophic bacteria and dissolved organic matter is rather different in rivers and estuaries. The aim of my thesis was to elucidate if bacteria are regulated differently in the Råne river and estuary during a spring situation. Surface water was collected at both locations and a bioassay performed to study limiting substances for bacterial production, proportion bio-available dissolved organic carbon (DOC) in the water and bacterial growth ...

Geological records of past sea ice, such as those contained in Arctic marine sediments, offer an opportunity to strengthen our understanding of long-term sea ice variability, provided unambiguous paleo-sea ice proxies can be developed. One such recently proposed proxy is IP₂₅, a highly branched isoprenoid alkene biosynthesized exclusively by sea-ice dwelling diatoms (Haslea spp.), which is well preserved in marine sediments and could be used to reconstruct past changes in spring sea-ice extent....

It is incumbent upon teachers to reach out to students through methods that capitalize on the students' own motivations. Because of the diversity of self-referential personal styles of learning, reaching every student with a cookie-cutter approach to teaching is nearly impossible. This report explores the application of a type of problem-based learning known as "Legacy Cycles" that apply web technology to answer challenges presented as scenarios. The scenarios give students a similar experience ...

Mesoscale eddies are relatively small structures that dominate the ocean variability and have large impact on large scale circulation, heat fluxes and biological processes.In the western Mediterranean Sea, a high number of eddies has been observed and studied in the past with in-situ observations. Yet, a systematic characterization of these eddies is still lacking due to the small scales involved in these processes in this region where the Rossby deformation radius that characterizes the horizon...

Models for the mean sea surface (MSS) are created by combining and interpolating on a specified spatial grid inhomogenous data sets from different satellites with different ground track coverage. There are various approaches in which the sea surface height (SSH) data from different satellites can be combined to create an accurate reference surface. The orbit errors (especially from the early missions) need to be reduced, and systematic biases between different satellites can be decreased by re-p...

Forty years (1958-97) of observed and four simulations of Arctic sea-ice concentration (SIC) data are compared to document and better understand Arctic sea-ice variability. The four simulations result from four different forcings, and they are used in an attempt to quantify the relative importance of thermodynamic and dynamic forcings in the Arctic and its peripheral seas. The four runs (A through D) are forced as follows: Run A is forced with monthly varying monthly mean wind stresses and month...

Textural evidence, high carbonate concentration and septarian cracks in dolomite and calcite concretions and beds of the Middle Ordovician Cloridorme and Cow Head formations indicate early carbonate precipitation during very shallow burial in uncompacted or little compacted host-sediments. These carbonates started to form at a depth not exceeding 5 m from the seafloor, where porosities were as high as 90%, and continued to grow in the sediment column to subsurface depth of 150 meters. Concretion...

Sea ice is a major component of the Earth's climate system and is believed to be a sensitive indicator of climate change. The North Water (NOW) refers to a region of anomalous sea ice conditions at the northern end of Baffin Bay. The dynamic sea ice cover is due to the presence of the NOW polynya. An explanation for the polynya's occurrence has yet to be confirmed. In this the is I studied the spatial and temporal patterns of sea ice cover within the North Water (NOW) in the context of polynya f...

The objective of this thesis was to investigate the physiological changes that sea lice (Lepeophtheirus salmonis) cause in Atlantic salmon (Salmo solar). Sea lice are parasitic copepods that naturally infect salmonids in low numbers across the Northern Hemisphere with infrequent epizootics. The increase in the period of these epizootics in wild salmonids has mirrored the rise of the aquaculture industry in coastal areas. Therefore, it is important to answer basic physiological questions abo...

The growing demand for hydrocarbon fluids, and the future expectation of insufficient onshore reserves, is driving the exploration and development of off-shore oil and gas fields. A significantly increasing number of the new fields are situated in deep water, placing significant constraints on the application of conventional platform (sea surface) systems. This has, by necessity, generated the rapid growth of sub-sea processing technology. / An integral part of a novel sub-sea natural gas dehydr...

This dissertation attempts to improve the understanding of spatial distribution and evolution of snow-covered sea ice as related to polar bear habitat. This will be accomplished at both the local (i.e. 1m spatial resolution) and regional scales (i.e. 100 km spatial resolution) for various types of first-year sea ice (FYI) through four primary objectives. The first primary objective (i.e. Chapter 3) examines the observed and modeled temporal evolution of snow over smooth FYI, as well as the est...

Mercury (Hg) has been recognized as a contaminant of global concern due to its high toxicity, as well as its ability to mobilize over long distances and biomagnify up through the food chain. The discovery of polar springtime atmospheric mercury depletion events (AMDEs) in the 1990s provides a new mechanism for enhanced atmospheric Hg deposition to the surface environment in the Arctic, yet questions remain on the process leading to AMDEs and the net contribution of AMDEs to Hg loadings to the A...

<p> During the 1970s to the 1990s, Steller sea lions (<i>Eumetopias jubatus</i>) in Alaska declined severely, resulting in the western stock's listing as endangered under the United States Endangered Species Act. The localized depletion of their main food source around rookeries and haul out sites was the primary cause of their depletion. The western stock has still not recovered to historical levels. Therefore, scientists have continued to study Steller sea lions diet and foraging habits. One a...

The sea ice extent change and variability of the Canadian Arctic Archipelago (CAA) are quite different compared to the Arctic as a whole due to its unique geographic settings. In this thesis, the sea ice retreat processes, the connection with other Arctic regions, and the linkages to the surface radiation flux in the CAA are examined. The sea ice retreat processes in the CAA follow a four-phase process: a slow ice melt phase that usually lasts until early June (phase 1); a quick melt phase w...

Meltwater pulse 1A (MWP-1A) is the largest land ice melt event of the last deglaciation. In a period of no more than 340 years, between 14.65 and 14.31 ka (Dechamps et al, 2012), ~10% of the total deglacial sea-level rise occurred (Hanebuth et al, 2000; Peltier and Fairbanks, 2006; Deschamps et al, 2012), resulting in the highest reported rate of global mean sea-level rise in the geological record, which may have exceeded 4 m per century (Deschamps et al, 2012). Yet, the implications of MWP-1A f...

Ten species of shallow water echinoid are found on the subtropical east coast of South Africa. Although their distributions are patchy, the most common species, Echinometra mathaei, stomopneustes variolaris and Diadema savignyi, are nontheless conspicuous components of intertidal communities on this coast. As little was known about these three species, the overall intention of this study was to provide some fundemental information on their biology and ecology. For the purposes of achieving this ...

Dinoflagellates are one of the most abundant and diverse groups of microalgae. Many dinoflagellates are covered with cellulose plates, whereas others lack these plates and are hence referred to as athecate or unarmoured. Unarmoured species have been historically poorly characterized because they deform when fixed with traditional methods. Most unarmoured genera are included within the order Gymnodiniales and are differentiated by morphological characters, but the recent combination of morphologi...

The European Commission manages fish stocks by applying a fishing mortality based on the maximum sustainable yield concept. So far most Baltic Sea fishing maximum sustainable yieldmodels have focused on one species at a time. The few existing multi-species models have assumed that a species’ maturity and growth is dependent on the availability of food. Our two-species models make it possible to investigate if there is a conflict between fishing maximum sustainable yield for cod and herring in th...

129I is a radioactive isotope (T1/2= 15.7 million years) produced through natural and anthropogenic pathways, but the anthropogenic production is presently dominating the Earth’s surface environments. Sparse data from previous investigations in the Baltic Sea clearly indicated the occurrence of 129I at levels 3-4 orders higher than natural pre-atomic era (before 1940) without comprehensive evaluation of distribution and inventory. In this thesis extensive data on the distribution and inventory o...

Permafrost carbon stores have been suggested to react to warming trends with increased terrestrial loading to its coastal waters. Presently, the warming has been seen to be especially high in the East Siberian Arctic and the fate of the major release of terrestrial matter to these coasts is yet to be detailed. Our work is focused on the East Siberian Shelf (ESS) – which is the largest continental shelf in the world. It receives substantial inputs of terrestrial organic matter both from the large...

Observations of feeding behaviour of common guillemots, Uria aalge, in June 2002 at the island Stora Karlsö in the Baltic Sea proper, and measurements of morphology and energy density in the prey fish sprat, Sprattus sprattus, showed that fish delivered to chicks at present are shorter and weigh less than in the 1970s. Long lasting attending periods and a feeding rate of 4.6 feeds per day indicate that parents are feeding their chicks at a maximum rate. Because of a decline in the energy density...
