Over the last decade pockmarks have proven to be important seabed features that provide information about fluid flow on continental margins. Their formation and dynamics are still poorly constrained due to the lack of proper three dimensional imaging of their internal structure. Numerous fluid escape features provide evidence for an active fluid-flow system on the Norwegian margin, specifically in the Nyegga region. In June-July 2006 a high-resolution seismic experiment using Ocean Bottom S...

A key determinant of atmospheric circulation patterns and regional climatic conditions is sea surface temperature (SST). This has been the motivation for the development of various teleconnection methods aiming to forecast hydro-climatic variables. Among such methods are linear projections based on teleconnection gross indices (such as the ENSO, IOD, and NAO) or leading empirical orthogonal functions (EOFs). However, these methods deteriorate drastically if the predefined indices or EOFs cannot ...

Regulation of tubulin gene expression in embryos of the sea urchin Lytechinus pictus has been experimentally investigated by use of cloned recombinant tubulin DNA and anti-tubulin antiserum. Tubulin synthesis appears to be autogenously regulated at the level of tubulin mRNA stability by the level of unpolymerized tubulin; i.e., the more unpolymerized tubulin, the less stable the tubulin mRNA. Destabilization of tubulin mRNA requires continued protein synthesis. Most of tubulin stored in eggs is ...

Tourism has become one of Egypt’s main sources of income and has undergone rapid privatization and subsequent growth. This has resulted in numerous policy and implementation gaps including those in environmental policy. Egypt’s natural resources are thus threatened by this unsustainable tourism growth. This study analyses the impact of the tourism privatization movement in Egypt on the distribution of environmental responsibility between the private and public sectors and the environmental conse...

This thesis attempts to solve a problem identified by the Swedish Maritime administration. The problem consists of birds, more precisely great cormorants, which stain lighthouses with their faeces. Initially an investigation of the great cormorants is performed. The cormorants thrive in great numbers nowadays in the Swedish archipelago after being extinct only a few decades ago. The faeces has a very foul smell and is therefore considered as a problem by maintenance personnel working on lighthou...

The Salish Sea includes Juan De Fuca Strait, Puget Sound, and the Strait of Georgia (SoG), which separates Vancouver Island from mainland British Columbia. Hake and herring are commercially important fish and both species use SoG as larval rearing grounds. Drift tracks of larvae for these species were simulated using a regional circulation model and a particle-tracking model, for up to six weeks after they hatch. Larvae with different behaviors (such as surface drifters or performing diel vertic...

Conventional fixed threshold detectors set a fixed threshold based on the overall statistical characteristics of the spatially uniform clutter over all ranges to give a specific probability of false alarm and detection. However, in radar applications clutter statistics are not known a priori. Constant False Alarm Rate (CFAR) techniques provide an adaptive threshold to estimate the clutter statistics and to distinguish targets from clutter. In Cell Averaging CFAR (CA-CFAR) the threshold is contro...

The Ross Sea polynya is characterized by high spatial and temporal variability and by an annual cycle of sea ice retreat, water column stratification, large phytoplankton blooms, and months of complete darkness. This region is also highly susceptible to increasingly changing climatic conditions that will significantly affect the hydrography, iron supply, primary production patterns and carbon cycling. This project focused on analyzing how differences in photosynthetic traits between the two majo...

Looking at the metabolite profile of an organism provides insights into the metabolomic state of a cell and hence also into pathways employed. Little is known about the metabolites produced by corals and their algal symbionts. In particular, corals from the central Red Sea are understudied, but interesting study objects, as they live in one of the warmest and most saline environments and can provide clues as to the adjustment of corals to environmental change. In this study, we applied gas chrom...

Future climate scenarios in the Baltic Sea project increasing sea surface temperature, as well as increasing precipitation and river runoff resulting in decreased salinity. These changes can severely impact the dynamics and function of brackish water communities, specifically phytoplankton. Phytoplankton are a significant source of organic matter to other trophic levels, and some species can be toxic. Their response to future climate conditions is of great relevance for the health of humans and ...

The brown macroalgae Fucus radicans is endemic to the Baltic Sea, but little is known about this newly described species. This thesis investigates the ecology and role of F. radicans within the species poor Baltic Sea ecosystem. The thallus of F. radicans had a more complex structure but was smaller than F. vesiculosus, the other important foundation species with which it grows in sympatry at several sites. The variability of the associated flora and fauna communities of these two Fucus species,...

Physicochemical speciation of metals in natural waters is very important for understanding their distribution, mobility, bioavailability and toxicity. To be able to understand the behaviour of an aqueous element and the transformation between chemical and physical species, there is a need for reliable methods that enable measurements of specific fractions of metals. Many different techniques are used for metal speciation, of which many suffer from problems. Ultrafiltration has frequently been us...

A method was developed for the determination of aluminum in sea water using oxine as a reagent. Extraction of aluminum oxinate by chloroform from acidic solution was impeded by the presence of fluoride in sea water. The fluoride Interference was less severe in basic solution and it was possible to extract aluminum oxinate from sea water at a pH of 8 with no loss of sensitivity due to the presence of fluoride. Iron and copper were complexed with cyanide in reducing solution and manganese oxinate...

During the present work, we studied the organic matter in British Columbia sea waters. A carbohydrate substance was found with the characteristics of a uronic acid. The approach was made in two ways: (1) By applying spectrophotometrically the phenol sulfuric acid test for the determination of sugars and related substances, as described by M. Dubois, K.A. Gilles, J.K. Hamilton, P.A. Rebers and F. Smith (11) directly to sea water without previous separation of sea water constituents, and (2), by a...

The determination of small amounts of uranium of the order of parts per hundred million has usually been carried out by indirect radioactive measurements. Such measurements cannot be employed except when the radio-elements are known to be in equilibrium. The separation of the uranium and its isotopes in such small amounts, is accomplished with the use of an ion-exchanger and separated in a radioactively pure state with the use of co-precipitators, the iron (and aluminum) being added. The alpha-p...

The sea tales of Edgar Allan Poe—"MS Found in a Bottle", The Narrative of Arthur Gordon Pym, and "A Descent into the Maelstrom"—form an interesting group that has often been overlooked. Together they deal with the problem of the fragmented personality, a theme that lay at the heart of many of Poe's tales. The sea is the arena in which the fundamental struggle against psychic division takes place. In testing a man to his limits, the sea also reveals new possibilities and new knowledge. Poe was a...

Wave power has been increasing the interest of many researchers looking for alternative sustainable energy sources since the reserves have proved to be capable of satisfying a considerable percentage of the world´s energy demands. This option has not been adopted as a sustainable source since there are some challenges in the process of designing a low cost device that converts the kinetic energy of the waves into electric energy and that could still be efficient enough to be competitive against ...

This thesis explores the issues of navigation and overflight of the territorial sea by military aircraft operating from warships, known as organic aircraft. A review of maritime zones in the Law of the Sea from a Canadian perspective reveals a preference for the exercise of coastal State jurisdiction on significant ocean space, to the potential detriment of freedom of navigation advocated by maritime powers. Current uses of organic air are challenged by a legal framework which does not take int...

The distillation of sea water is of importance for the future demands for potable water and other uses in the world. A novel technique, based on electrohydrodynamic (EHD) principles, was used in this realm to desalinate artificial sea water of 3.3% (w/V) concentration. A single point corona electrode was operated at a potential of 5.3 kV (maximum output current 0.3 mA), and was installed one cm over the surface of sea water. The flux of air ions was about 3.0 $ times$ 10$ sp{12}$ cm$ sp{-2}$ s$ ...
