Preferential Fish Consumption Based On Omega-3 Fatty Acids And Mercury Concentrations For Maximum Health Benefits, Katrina Smith
Honors Theses
The regular consumption of seafood offers a variety of protective effects, including the reduction of the risk of cardiovascular disease and stroke, due to the presence of omega-3 fatty acids in fish. These protective effects may be diminished by the contamination of seafood by mercury. Mercury increases the risk of cardiovascular problems and impedes neurological development. The objective of this project was to determine the fish species that are appropriate for consumption based on low levels of mercury and recommended intake levels of omega-3 fatty acids. Species that are high in omega-3s and low in mercury include salmon, trout and …

Rhizocephalan Parasites Of Mud Crabs In South Carolina Estuaries, Erin Burnette
Honors Theses
Rhizocephalan parasites often infect commercially important crustacean species such as the blue crab (Callinectes sapidus). In this experiment, the prevalence of rhizocephalan parasites was determined by sampling mud crabs (Panopeus herbstii) in three different locations; Huntington Beach State Park, Waites Island, and Murrells Inlet. Crabs were determined to be parasitized by the presence of an externae extruding from their apron. Unparasitized crabs were also collected to serve as a control group. The externa were removed and DNA extractions were performed. Polymerase chain reactions (PCR) were done to prove whether the crabs were parasitized by Loxothylacus texanus or Loxothylacus panopaei. Results …

Barcoding Of Arrow Worms (Phylum Chaetognatha) From Three Oceans: Genetic Diversity And Evolution Within An Enigmatic Phylum, Robert M. Jennings, Ann Bucklin, Annelies Pierrot-Bults
Biology Faculty Publication Series
Arrow worms (Phylum Chaetognatha) are abundant planktonic organisms and important predators in many food webs; yet, the classification and evolutionary relationships among chaetognath species remain poorly understood. A seemingly simple body plan is underlain by subtle variation in morphological details, obscuring the affinities of species within the phylum. Many species achieve near global distributions, spanning the same latitudinal bands in all ocean basins, while others present disjunct ranges, in some cases with the same species apparently found at both poles. To better understand how these complex evolutionary and geographic variables are reflected in the species makeup of chaetognaths, we analyze …

The Role Of The Alaskan Stream In Modulating The Bering Sea Climate, Tal Ezer, Lie-Yauw Oey
CCPO Publications
A numerical ocean circulation model with realistic topography, but with an idealized forcing that includes only lateral transports is used to study the role of the Alaskan Stream (AS) in modulating the Bering Sea (BS) variability. Sensitivity experiments, each one with a different strength of the AS transport reveal a nonlinear BS response. An increase of AS transport from 10 to 25 Sv causes warming (similar to 0.25 degrees C mean, similar to 0.5 degrees C maximum) and sea level rise in the BS shelf due to increased transports of warmer Pacific waters through the eastern passages of the Aleutian …

Differential Damages Sustained From Hurricane Ike On Varying Growth Forms Of Coral At Distinct Locations Off The Coast Of South Caicos, Turks And Caicos Islands, Caitlyn A. Kenny
Pell Scholars and Senior Theses
In September 2008, Hurricane Ike hit South Caicos, Turks and Caicos Islands as a Category 4 hurricane. This study examines the differential damages caused to varying common growth forms, size, locations, and depths of coral by Hurricane Ike on South Caicos reefs. Belt transect techniques as well as line intercept techniques were conducted at nine sites, looking at 14 common species of coral, representing four different growth forms. A total of 9,011 coral colonies were surveyed. 2,832 colonies (31.4%) were found to have at least one type of damage. It was expected that branching and digitate growth forms as well …
A Test Of The Area Of Refuge Hypothesis In Indo-Pacific Marine Biogeography,

A Test Of The Area Of Refuge Hypothesis In Indo-Pacific Marine Biogeography, Jonnell C. Sanciangco
Biological Sciences Theses & Dissertations
Many hypotheses have been proposed to explain the marine biogeographic patterns of species richness of the Indo-Pacific. One of these hypotheses suggests that available habitat area is the main predictor of species richness. This is the basis for the area of refuge hypothesis that attempts to explain the global maxima of species richness found in the Coral Triangle, the area encompassing mostly the Philippines, Indonesia, and Malaysia. This species-area effect also has habitat heterogeneity as a potential component. The purpose of this study is to test the effects of habitat availability predictors, such as shallow water area and coastline length …

Abundance Of Ammonia-Oxidizing Archaea And Bacteria Along An Estuarine Salinity Gradient In Relationship To Potential Nitrification Rates, Anne E. Bernhard, Zachary C. Landry, Alison Blevins, José R. De La Torre, Anne E. Giblin, David A. Stahl
Biology Faculty Publications
Abundance of ammonia-oxidizing Archaea (AOA) was found to be always greater than that of ammonia-oxidizing Bacteria along an estuarine salinity gradient, and AOA abundance was highest at intermediate salinity. However, AOA abundance did not correlate with potential nitrification rates. This lack of correlation may be due to methodological limitations or alternative energy sources.

The atmospheric circulation patterns associated with the Pacific quasi-decadal oscillation (QDO) are investigated using available observational data from 1948 to 2007. Previous studies indicate that the Pacific QDO is characterized by a distinct lifecycle in the form of sea surface temperature (SST) patterns. In the warm and cool phases of the Pacific QDO, the SST patterns resemble those associated with the El Niño-Southern Oscillation (ENSO). During the warm–cool and cool–warm transitions of the Pacific QDO, recurrent SST patterns are also clearly visible. The rotated empirical orthogonal function analysis on the 10–15 year filtered data shows that the evolutions of SST …

Peconic Bays Estuary Benthic Gis Data, Robert M. Cerrato
SoMAS Research Data
Benthic habitat maps of the estuary seafloor can increase our knowledge of the range and variability in benthic habitats, assist managers in their efforts to protect and/or restore commercially and recreationally important finfish and shellfish, link land usage (e.g. developed vs. undeveloped areas) and water quality data to benthic habitat quality, and make it possible to utilize faunal data as a long-term indicator of the overall “health” of the estuary. This study combined high-resolution sonar surveys with physical and faunal characteristics at point locations in different seafloor areas of the Peconic Bays Estuary. Sonar mapping used multibeam swath bathymetry to …

Development Of A Spectral 2-D Fast Fourier Transform Analysis For Sand Ripple Morphology Interpretation, Christopher M. Englert
Honors Theses
A MATLAB-based 2-Dimensional Fast Fourier Transform spectral analysis is developed and tested for its applicability to bedform morphology and hydrodynamic data from a hydrodynamically complex field site. The aspects of the procedure tested are (1) the use of an 8 sub-region arrangement for analysis versus five other arrangements, (2) the procedure for averaging the wavelength-and-orientation outputs from each sub-region to produce a single representative value for each image, (3) methods for eliminating and/or filtering poor quality data, and (4) the procedural steps in the spectral analysis that can appropriately incorporate automation versus manual involvement and interpretation. The automated technique is …

On The Nature Of Winter Cooling And The Recent Temperature Shift On The Northern Gulf Of Alaska Shelf, Markus A. Janout, Thomas J. Weingartner, Thomas C. Royer, Seth L. Danielson
CCPO Publications
[1] In spring 2006 and 2007, northern Gulf of Alaska (GOA) shelf waters were ∼1.5°C below average throughout the similar to ∼250 m deep shelf and the salinity-dependent winter stratification was anomalously weak due to above (below) average surface (bottom) salinities. Spring 2007 and 2008 temperatures were also similar to ∼-1.5°C below average, but the anomalies were confined to the upper 100 m due to moderate salt stratification. Shelf temperatures in these 2 years were among the lowest observed since the early 1970s, thus interrupting an approximately 30-year warming trend. We examined winter cooling processes using historical conductivity-temperature-depth (CTD) profiles …

Mixing By Shear Instability At High Reynolds Number, W. R. Geyer, A. C. Lavery, M. E. Scully, J. H. Trowbridge
CCPO Publications
Shear instability is the dominant mechanism for converting fluid motion to mixing in the stratified ocean and atmosphere. The transition to turbulence has been well characterized in laboratory settings and numerical simulations at moderate Reynolds number-it involves "rolling up", i.e., overturning of the density structure within the cores of the instabilities. In contrast, measurements in an energetic estuarine shear zone reveal that the mixing induced by shear instability at high Reynolds number does not primarily occur by overturning in the cores; rather it results from secondary shear instabilities within the zones of intensified shear separating the cores. This regime is …

The elemental composition of otoliths may provide valuable information for establishing connectivity between fish nursery grounds and adult fish populations. Concentrations of Rb, Mg, Ca, Mn, Sr, Na, K, Sr, Pb, and Ba were determined by using solution-based inductively coupled plasma mass spectrometry in otoliths of young-of-the year tautog (Tautoga onitis) captured in nursery areas along the Rhode Island coast during two consecutive years. Stable oxygen (δ18O) and carbon (δ13C) isotopic ratios in young-of-the year otoliths were also analyzed with isotope ratio mass spectrometry. Chemical signatures differed significantly among the distinct nurseries within Narragansett …
