Marine consumers and their prey display plasticity that affects the outcomes of their dynamic interactions as well as community structure and ecosystem function. Aquatic chemical signals induced plasticity in consumers and prey from a broad range of taxonomy (phytoplankton to fishes), sizes (microscopic to macroscopic), and habitats (pelagic to benthic), and this complex plasticity strongly affected consumer-prey interactions. Two fishes,

Recently, carbon dioxide injection into deep sea sediments has become one of the carbon dioxide mitigation methods since carbon dioxide hydrates are stable at the prevailing pressure and temperature conditions. The Black Sea, which is one of the major identified natural methane hydrate regions of the world, can be a good candidate for carbon dioxide storage in hydrate form. Injected carbon dioxide under the methane hydrate stability region will be in contact with methane hydrate which should be ...

Tsunamis, as the catastrophic disasters, can cause loss of live and property when they come to the shores. Preparation of emergency plans is essential to reduce the damage. Consequently, any initiative in tsunami modeling and inundation mapping is of vital importance for progressing safety surveillance and maintenance. In an effort to achieve a thorough analysis of effect of tsunami, it is critical to estimate the geographical extent of possibly affected area and to predict tsunami impacts. The ...

Abstract The European eel (Anguilla anguilla) migrates to the Sargasso Sea to spawn. Even though the biology of A. anguilla leptocephali in the Sargasso Sea has been studied for several decades, information regarding their diet has remained unknown until now. Previous dietary studies concerning other species of leptocephali in the Pacific Ocean have been limited to the recognition of identifiable prey remains amongst gut contents. Hence, in this study a molecular approach relying on the detectio...

The essay is a study of The Glassy Sea by the Canadian author Marian Engel. The novel focuses on the main character's self exploration ans her search for identity. A Jungian approach to this novel is particularly appropriate since the author makes use of several achetypes and symbols. Moreover, the novel is presented in an introspective manner that brings to the mind the method of self-examination used in psychoanalysis. The essay studies the development of the main character's identity, Rita. H...

The subject of this thesis is sea keeping and stability of a fishing vessel in regular waves, with focus on parametric roll resonance. Parametric roll resonance is resonance in roll due to time variation of a parameter, in this case the metacentric height or the restoring term. This variation is caused by the ship moving in waves, and is hence a function of heave, roll, pitch roll and time. We have made a mathematical model based on strip theory that can calculate the linear ship motions. The re...

Human-induced eutrophication is indirectly affecting aquatic organisms by altering their environment. This brings on altered selective pressures and could thereby cause changes in the genetic composition of exposed populations. Since anthropogenic environmental changes are usually occurring at a much higher rate than naturally occurring changes, they force populations to adapt to the new conditions faster than normal. Here, I have studied populations of three-spined sticklebacks (Gasterosteus ac...

Beaches occur throughout the coastal regions of the world. Ridges found on beachescan be used as indicators of past climatic and oceanographic conditions. Sea-levelchanges can also be extrapolated from these landforms, if the correct conditions occur, when the facies between eolian and intertidal sediments can be found. Groundpenetrating radar and fieldwork has been used to investigate the origins, processes, and the connection with sea-level fluctuations on a beach and the associated berm-ridge...

Sea level rise (SLR) is directly influenced by climate change through the processes of temperature affecting the growth and decay of continental ice (Barron and Thompson 1990). It is a significant environmental challenge that threatens coastal areas of many nations throughout the world. The Intergovernmental Panel on Climate Change (IPCC) Fourth Assessment Report issued in 2007 states that SLR poses a serious challenge to sustainable development along many coastal areas. The objectives of this t...

Uniola paniculata, commonly known as sea oats, is a C4 perennial grass capable of stabilizing sand dunes. Although this species is extensively used in beach restoration projects, production and availability of sea oats seedlings is seriously constrained due to disappearance of the natural stands. Other limitations are poor seed production, seed dormancy, and low seedling survival. With increasing interest in dune restoration, an efficient micropropagation technique is essential to generate sea o...

The diets of a transitory fish (spotted sea trout, Cynoscion nebulosus) and a fish with presumed greater site-fidelity (pinfish, Lagodon rhomboides) were analyzed with respect to habitat. Sampling occurred in Barataria Bay, Louisiana between May 2003 and May 2004. Spotted sea trout were caught using gillnets, and pinfish were caught using baited fish traps. Each gear was used on three habitats: mud bottom, oyster shell, and marsh edge. In addition, sampling for spotted sea trout was repeated at ...

Changes in runoff from Greenland and Antarctica are often cited as one of the major concerns linked to anthropogenic changes in climate. The changes in mass balance, and associated changes in sea-level, of these two ice sheets are examined by comparing the predictions of the six possible combinations of two climate models and three methods for estimating melting and runoff. All models are solved on 20 and 40 km grids respectively for Greenland and Antarctica. The two temperature based runoff par...

Deep-sea bamboo coral (Isidella sp.) SE000901A from the southern Oregon coast (water depth 1048m) provides a high-resolution record of variability of North Pacific Intermediate Water (NPIW) and carbon rain to the sea floor, related to coastal upwelling, from 1808 to 2000AD. Counting of annual layers in magnesium to calcium (Mg/Ca) variations, measured by electron microprobe analysis, yields a detailed age model that is transferred directly to records of carbon and oxygen isotope ratios (δ¹³C and...

Sea level and the alongshore component of wind stress data at seven locations on the Pacific coast of Canada and the United States were analyzed. The effective data period was from August 1, 1973 to September 9, 1975. The seven locations were Tofino, British Columbia; Neah Bay and Toke Point, Washington; South beach (Newport) and Charleston, Oregon; and Crescent City and San Francisco, California. Sea level relative to the two year mean is higher at the northern locations during the winter month...

A phytoplankton bloom dominated by the pennate diatom Nitzschia curta (Van Heurck) Hasle was observed during January-February 1983 at a receding ice-edge in the Western Ross Sea, Antarctica. The core of the bloom was found between 100-150 Km from the ice-edge. Nitzschia curta cell densities up to 22 x 10⁶ cells/1 were observed. The nanoplankton contributed to 18% (average) of the total biomass. The contribution of another pennate diatom, Nitzschia closterium (Ehrenberg) W. Smith, was significant...

Solar radiation intensities, incident to the sea surface off the Oregon coast, are measured and compared. Simplification of some physical and biological problems can be anticipated if the average radiation received over a broad segment of ocean can be accurately indicated by the amount recorded at the land station. The area of ocean over which the study was made extends the length of the Oregon coast and 165 miles to sea. The measurements were made during the months of June, July, August, and Se...

A deep source-receiver seismic refraction experiment was conducted on the upper part of the Monterey Deep Sea Fan. The aim of this thesis is to construct the velocity structure of the upper Monterey Fan and to examine the lateral seismic velocity variations among the upper, middle and lower fan subunits. Using primary waves and whispering gallery phases (the multiply-reflected refraction waves), the sediment velocity structure was modeled by the tau-zeta travel time inversion process. The change...

Three seismic refraction profiles obtained between 42°N and 43°N along the median valley of the Gorda Ridge, an active spreading center, allow the computation of the velocity structure underlying the valley. Wide angle reflections which appear on the seismic records suggest the existence of a velocity inversion underlying layer 3 and were analyzed in combination with refraction arrivals. The resulting velocity model has a low velocity zone with a directly-determined velocity of 5.72 km/sec, betw...

The specific activity of ⁶⁵Zn (nanocuries ⁶⁵Zn/g total Zn) was determined in various organs of the common coastal mussel, Mytilus californianus Conrad, collected from six locations along the Pacific Coast. These organs included the gills, mantle, foot, reproductive organs, adductor muscle, and viscera. After ashing and dissolving with nitric acid (8 M), each tissue was analyzed for ⁶⁵Zn by gamma-ray spectrometry. The determination of total zinc concentrations of the various organs was accomplish...

Spectral analysis was used to investigate semidaily mean sea levels and atmospheric pressures at San Francisco, California, Coos Bay, Oregon, and Tofino, British Columbia, in the frequency band 0 to 0.5 cpd. Cross spectral analysis of semidaily mean sea levels and atmospheric pressures at the three stations show that the response of sea level to low-frequency atmospheric pressure fluctuations is nonbarometric in the frequency band studied, and varies with season. Cross spectral analysis of semid...

Allocentrotus fragilis (Jackson) was obtained from six stations at depths of 100 to 1260 m on the continental shelf and upper slope off Newport, Oregon. Ages and growth rates of A. fragilis were determined by two methods: 1) A procedure was developed to make growth zones of the skeletal test plates visible. Alternating light and dark growth zones were found to be formed semi-annually. The total number of growth zones was used to indicate the urchin's age. 2) Age and growth rate values were also ...

The objective of this thesis is to show that by separating the two major anthropogenic changes caused in riverine input to the north shore of the Black Sea, it is possible to describe distinct linkages between ongoing ecological changes in the Black Sea, and 1) flow reduction, and 2) nutrient load increase. An attempt is made to quantify the pertinent changes in the inputs of water, salt, and nutrients by modelling individual fluxes over time. The results of these computations are used to argue ...

Sea level and current data collected near Newport, Oregon are compared to determine an empirical relationship from which the low frequency (f < .1 cpd) alongshore current field over the continental shelf is estimated from observed sea level measurements at the coast. Regression analysis of the near-surface (20-25 m) currents with sea level indicates the surface currents are in geostrophic balance with the sea surface slope. Analysis of the alongshore shear between the near-surface and deep (75-8...

A criterion is defined to compare seasonal ice coverage in the Greenland Sea for the years 1900-57, and the areal coverage is graphed using the 1898-1913 average as a standard. The factors wielding possible influence on short-term variations of the ice cover are examined individually and their relative importance established. The influence of ocean currents is evaluated by analysis of hydrosections across the East Greenland Current at 74°-76° N and across the North Atlantic Current in the Faeroe...

The North Sea basin is one of the best-studied areas in the world with respect to thestructural and sedimentary architecture of rift zones. The Base Cretaceous Unconformity,which defines a mappable horizon at the transition from synrift to postrift sequencesassociated with the Jurassic&#150;Cretaceous rift, is well known as a reference marker for bothseismic and well log interpretations and covers most of the basin. This unconformity isinterpreted at the locations of the &#216;ygarden Fault Zone...

We use rock physics models for poorly consolidated rocks to diagnose reservoir sandstones in the Alvheim Field, North Sea. Geological factors that will control the rock physics and seismic properties include clay content, sorting, diagenesis, mineralogy, and bedding configuration. The various geologic factors will affect the fluid and stress sensitivity in these rocks. We investigate the interrelationships between various geological factors and seismic fluid and stress sensitivity, by combining ...

Due to high expectancy of hydrocarbon resources in the Beaufort Sea itis seen as an important area for energy in the future. As the focus nowis shifting towards the deeper parts of the sea, there is a need for floatingproduction platforms that are able to operate year-round in the harsh con-ditions of the Beaufort Sea. In this Master&#146;s thesis the design of such aplatform is performed, with respect to global ice loads acting on the plat-form and the capacity of the stationkeeping system. Thi...

To facilitate the process of setting up small scale environmental models in coastal and offshore areas a wave model and a 2D current model for the Baltic Sea have been set up with MIKE 21. The ambition is that the Baltic Sea model can serve as a source of boundary conditions for local models. The main focus in the project has been to determine which input data to use to get the best results and then to calibrate and validate the model with the best data sets available. The wave model has been te...

For decades the Baltic Sea has been subject to eutrophication due to heavy anthropogenic nutrient loads on the aquatic ecosystem. Quantitative projections of its effects require an understanding of its driving mechanisms, i.e., the hydrodynamics that are responsible for the physical transport and mixing and the biogeochemical nutrients pathways within the algal ecosystem and between the particulate and dissolved phases in the water and in the sediments. A simple basin-scale hydrodynamic framewor...

Sturgeons belong to one of the oldest families of bony fish in existence, having their first appearance in the fossil records approximately 200 million years ago. Their natural habitats are found in the subtropical, temperate and sub-Arctic rivers, lakes and coastlines of Eurasia and North America. In the Romanian waters, five anadromous species of sturgeon, out of the total 25 species known by science, once migrated from the Black Sea into the Danube for spawning: beluga; Huso huso, Russian s...

The stellate sturgeons as well as the other sturgeon populations inhabiting the Lower Danube River system (LDR) and the NW part of the Black Sea have experienced a severe decline due to heavy fishery, river regulation and water pollution. Traditionally, sturgeons have represented a great economic value for the countries along the Danube, being fished mainly for their eggs, the “black caviar”. The human population along the Danube River took advantage of the anadromous behaviour of these fishes a...

One common idea within participation theory is the need for new approaches in decision making that emphasize a two-way interaction between decision makers and the public as well as deliberation among participants. Citizens should be given the opportunity to weigh evidence, discuss and debate potential decision options and possibly arrive at mutual agreements by which all parties can abide. The demand for sound scientific information and public participation is particularly great especially in ad...

In the atmosphere vertical extended layers that are in the state of super saturation with respect to ice can appear; these layers have been termed ice-supersaturated layers (ISSL). If an aircraft passes through an ISSL, persistent condensation trails can form. These contrails absorb the long wave radiation from the earth and reflect the incoming short wave radiation from space. The absorbing effect of the long wave radiation is although greater than the reflecting effect of the short wave radiat...
