The Ross Sea, Antarctica seasonal phytoplankton bloom is one of the largest in the Southern Ocean. This project focuses on the biological pump, which removes carbon from the surface ocean to the deep ocean through the settling of particulate organic matter, the advection of dissolved organic carbon, and active flux due to vertical migration of zooplankton. The objective of this study was to focus on three interrelated components of the biological pump including sedimentation, photosynthetic rate...

Movement of Atlantic Water into the Kara Sea is controlled by the bathymetry which funnels the inflow up three canyons along the eastern margin of the Svyataya Anna Trough. Mixing of the warm, saline Atlantic Water in these canyons with the considerable summer outflow of the Ob-Yenisey rivers results in the formation of Arctic Bottom Water and due to the presence and cooling by ice, in the formation of Arctic Surface Water. Both of these water masses then exit the Kara Sea as deep and shallow co...

Aerial surveys are commonly used to evaluate in-water sea turtle abundances. A correction is applied to account for turtles diving below the observed surface. Historically, observations of summer/fall surfacing behavior were used for this correction, assuming constant behavior among seasons. Using radio/acoustic telemetry, seasonal differences in sea turtle surfacing behavior were determined among Kemp's ridleys and loggerheads. Mean time spent at surface in the spring ranged between 9.9%-30.0% ...

Flipper-tagging, aerial surveys, and satellite telemetry was used to investigate the occurrence, migratory routes, distances traveled, swimming speeds, diving behavior, and the relation of water temperature to movements and timing of migration of wild loggerhead (Caretta caretta) and Kemp's ridley (Lepidochelys kempii) sea turtles. The behavior and movements of head-started loggerhead turtles was investigated with satellite telemetry and compared to wild turtles. Flipper-tagged loggerhead and Ke...

The Northern North Sea and the Patagonian Shelf have similar characteristics, and their circulation is determined by strong tidal regimes, significant wind-driven flow, and by density gradients to a lesser degree. The influence of oceanic currents is notable in the Patagonian Shelf, where the Falkland Current flows along the shelf edge, but less important in the North Sea. While the North Sea is perhaps the most studied body of water in the world, the circulation of the Patagonian Shelf have rem...

I present here an investigation of several aspects of the biology of sea turtles in the mid-Atlantic Bight. During 19 years of data collection, included in this study, strandings have increased for all species of sea turtles in Virginia. Most sea turtle strandings occurred during the spring when juvenile turtles migrate into the Bay (Kemp's ridleys had a second significant stranding peak, during fall migration) along the Southern Bay and Virginia Beach Oceanfront. Sea turtles utilize the Chesape...

O ambiente marinho é objeto de uma atenção crescente e constitui um ambiente dinâmico e multidimensional que é muito exigente para a recolha e atualização dos dados, requerendo grandes quantidades de dados. Estes dados são únicos uma vez que as campanhas onde foram recolhidos são irrepetíveis, devido à existência de diversos fatores que estão fora do controlo dos investigadores. Além disso, o financiamento para estas campanhas pode ser difícil de conseguir. No entanto, estes conjuntos de dados s...

A numerical simulation is used to predict the time evolution of the solidification of sea ice, as well as the internal channel distribution and solute rejection rate resulting from a top-chilled scenario. This situation is commonly found in nature due to the freezing of seawater over large areas of the globe. Similar processes occur during the solidification of magma bodies inside the Earth. Examples in industry include the solidification of alloys, crystal growth, and freezing of food products....

The feedback between clouds and sea ice got more importance in the last years, because of the declining Arctic sea ice extent. Previous observations show the formation of low clouds over newly formed open water. These low clouds are very important for the Arctic Energy Budget, because they warm the surface. This leads to increasing temperatures and stronger sea ice loss. To assess the relationship between sea ice cover and cloudiness, satellite observations by DARDAR were compared with both glob...

The variations in the sea breeze are examined both diurnally and interannually along the panhandle of Florida during the boreal summer season. A climatology of sea breeze cross sections is calculated eight times daily between the years 1979 and 2001 to examine diurnal differences. The cross sections are created using very high resolution dynamically downscaled analyses from the NCEP-DOE (R2) and the ECMWF ERA-40 for the southeast U.S. The high resolution downscaled product is validated with othe...

Increasing sea levels have the potential to place important portions of the infrastructure we rely on every day at risk. The transportation infrastructure relies on roads, airports, and seaports to move people, services, and goods around in an ever connected global economy. Any disturbances of the transportation modes have reverberating effects throughout the entire economic spectrum. The effects include delays, alterations of routes, and possible changes in the origin and destinations of servic...

The aeolian transport of aerosols (mineral dust from desert areas, smoke and ash from biomass burning, and from anthropogenic emissions) is an important process for introducing bioactive trace elements to the surface ocean and can have a large impact on marine primary production. All material that enters the ocean from the atmosphere must pass through the air-sea interface, or sea surface microlayer. The microlayer is the physical link between the sea surface and lower atmosphere and is therefor...

Sea urchin U1 genes coding for the major embryonic U1 RNA are in the tandemly repeated units. The U1 repeat unit in L. variegatus is variable in size from 1.2 to 1.4 Kb while that in S. purpuratus has a homogenous size of 1.1 Kb. Two types of U1 repeats have been isolated from L. variegatus. They are conserved in the 5$\sp\prime$ flanking region for 500 bp, but vary in the 3$\sp\prime$ flanking sequence immediately after the CAAAGAAAGAAAA sequence necessary for 3$\sp\prime$ end formation. The ta...

An attempt is made to predict the sea-surface temperature in the Yellow Sea in winter. A simple numerical model is adopted for the task so that the construction of the adjoint model is tractable. Direct observations of currents and sea-level fluctuations are used to establish the viability of the forward model. Published regional sea-surface temperature distributions then provide a basis for optimizing both the initial condition and the sea-surface heat flux in the integration of the heat equati...

A high resolution limited area model with realistic bottom topography has been developed for the East China Sea, based upon the primitive-equation GFDL ocean model. Solutions are obtained for an ocean driven by annual mean heat and fresh-water forcing at the surface, and specified advective transports of mass, heat, and salt at the open boundaries. / Analysis of temperature and salinity on various isopycnal surfaces suggests that the mixing was confined to the surface layer, and that the entrain...

Thesis advisor: David R. Burgess / Establishment and maintenance of cell polarity has become an increasingly interesting biological question in a diversity of cell types and has been found to play a role in a variety of biological functions. Previously, it was thought that the echinoderm embryo remained relatively unpolarized until the first asymmetric division at the 16 cell stage of development. However, there is mounting evidence to suggest that polarity is established much earlier. I analyze...

As ocean temperatures continue to rise, the effect of temperature on marine organisms becomes highly relevant. The Red Sea is the warmest sea and is rapidly warming with current surface temperatures (28 – 34 °C) already exceeding those of most tropical systems. This has major consequences for organisms that may already find themselves at their thermal limits. The aim of this project was to define the thermal limits and thresholds of certain Red Sea species. Firstly, to better understand the ther...

Eddies are one of the key features of the Red Sea circulation. They are not only crucial for energy conversion among dynamics at different scales, but also for materials transport across the basin. This thesis focuses on studying the characteristics of Red Sea eddies, including their temporal and spatial properties, their energy budget, the mechanisms of their evolution, and their predictability. Remote sensing data, in-situ observations, the oceanic general circulation model, and data assimilati...
