Coastal Inundation Due To Storm Surge As Sea Level Changes Along The Northern South Carolina And Southern North Carolina Coast, Justin Hartnett
Honors Theses
This study made use of the storm surge model in Peng, Xie, and Pietrafesa (2004) and Xia et al. (2004), to predict coastal inundation along northern South Carolina and southern North Carolina as sea level rises. Hurricane Hazel (1954) was used as the reference hurricane in this study, which made landfall at 33.85°N, 78.57°W, as a category 4 hurricane. Data was plotted and analyzed using Matlab, to produce inundation maps for four sea level rises (0.2m, 0.6m, 1.0m, and 2.0m). The greatest net storm surge was produced during a 2m sea level rise, which in return caused the greatest amount …

A Comparison Of Fish Growth Rates In A Pristine And An Urbanized Salt Marsh Estuary, Katherine Stohl
Honors Theses
Fish grow as they age, but not all fish grow at the same rate. Internal and external factors such as stress and food availability can change the growth rate. This study looks to see if the growth rates vary between North Inlet and Murrell’s Inlet, SC for red drum and striped mullet. Red drum grew faster and showed a typical length-frequency graph in North Inlet. The cause of the difference in growth was not tested, but human influence on the estuaries was considered to be a possible factor.

Ecological relationships of krill and whales have not been explored in the Western Antarctic Peninsula (WAP), and have only rarely been studied elsewhere in the Southern Ocean. In the austral autumn we observed an extremely high density (5.1 whales per km2) of humpback whales (Megaptera novaeangliae) feeding on a super-aggregation of Antarctic krill (Euphausia superba) in Wilhelmina Bay. The krill biomass was approximately 2 million tons, distributed over an area of 100 km2 at densities of up to 2000 individuals m−3; reports of such ‘super-aggregations’ of krill have been absent in …

Investigating The Potential For Nitrate-N Removal In Rhode Island Transient Headwater Streams, Molly Welsh, Kelly Addy, Art Gold, Suzanne Cox
Discovery@URI
Excess nitrogen (N) can have detrimental effects on the environment, particularly in coastal waters where inputs from septic systems and agricultural runoff can lead to algal blooms and hypoxic zones. However, transient headwater streams, which comprise a significant portion of streams in watersheds, may have the potential to remove N given their low flow rates, high surface to volume ratios, long retention times, and hydric soils. We investigated the physical characteristics and N removal capacity of transient headwater streams. Four bromide (Br) and nitrate-N slug tests were conducted in four streams in southern RI. Streams were sampled repeatedly as the …

Population Dynamics Of Sheepshead (Archosargus Probatocephalus; Walbaum 1792) In The Chesapeake Bay Region: A Comparison To Other Areas And An Assessment Of Their Current Status, Joseph Charles Ballenger
OES Theses and Dissertations
Sheepshead recently have seen an increase in fishing pressure in Virginian waters of the Chesapeake Bay. This increase in fishing pressure has led to demands to install effective management measures to protect the fishery. However, no study regarding the population dynamics, and thus potential yield, of sheepshead has been conducted north of Cape Hatteras. We addressed the need for information regarding the population dynamics of Chesapeake Bay sheepshead by investigating their age distribution, growth rate and reproductive biology. We used this information to construct yield-per-recruit models, which local management agencies may use in the formation of scientifically based management measures. …

Henry Hudson first sailed toNew Yorkharbor 400 years ago. Since then,New York Cityhas both affected and been affected by water quality in greaterNew YorkHarbor. In this paper, we focus on sewers, sewerage, and sewage treatment inManhattanand their effects on theHudson River. It is clear that feedbacks among drinking water quality and quantity, population, public perceptions, regulations, and estuarine water quality exist, although their strength and character have varied over time. Early land uses damaged local water supplies found on ManhattanIsland. New Yorkthen began to exploit the large fresh water resources available to its north, which helped the City to expand …

Evaluating Methods For Optimizing Classification Success From Otolith Tracers For Spotted Seatrout (Cynoscion Nebulosus) In The Chesapeake Bay, Stacy Kavita Beharry
OES Theses and Dissertations
Identifying the natal sources of fish is an important step in understanding its population dynamics. Adult recruits are often sourced from multiple nursery areas, with good quality locations contributing disproportionately more fish to the adult stock. Because population persistence is strongly influenced by nursery habitat, methods that correctly identify the source of recruits are necessary for effective management. Within the last decade, otolith chemistry signatures have been increasingly used as a natural marker to delineate fish from a mixture of nursery sources. Despite the widespread use of otolith trace element and stable isotope ratios as habitat markers, the statistical approaches …

OES Faculty Publications
Research on assessment and monitoring methods has primarily focused on fisheries with long multivariate data sets. Less research exists on methods applicable to data-poor fisheries with univariate data sets with a small sample size. In this study, we examine the capabilities of seasonal autoregressive integrated moving average (SARIMA) models to fit, forecast, and monitor the landings of such data-poor fisheries. We use a European fishery on meagre (Sciaenidae: Argyrosomus regius), where only a short time series of landings was available to model (n=60 months), as our case-study. We show that despite the limited sample size, a SARIMA model could …

Anaerobic Oxidation Of Methane And The Stoichiometry Of Remineralization Processes In Continental Margin Sediments, David J. Burdige, Tomoko Kamada
OES Faculty Publications
In many coastal and continental margin sediments, pore-water property-property plots yield values of rc:s, the stoichiometric ratio of dissolved inorganic carbon (DIC) produced to sulfate reduced, that are lower than the commonly assumed value of 2. Remineralization of organic matter more reduced than CH2O can cause such observations, as can DIC loss due to authigenic carbonate precipitation. However, through studies of Santa Monica Basin sediments, we have observed that these observations could also be related to the occurrence of anaerobic oxidation of methane (AOM) in sediments. Specifically, using a reactive transport sediment model, we have shown …

Diel vertical migration is widespread across diverse taxa in the world's lakes and seas, yet its biogeochemical consequences are still poorly understood. The biologically mediated vertical flux of material in the ocean (also known as the "biological pump") is a matter of major interest and concern, as it is thought to play an important role in regulating ocean carbon storage, and by extension, the global carbon cycle. Recent studies spanning multiple trophic levels from fish to dinoflagellates have led us to a concept of coupled vertical migrations that we refer to as "cascading migrations". That is, migrations that …

Modern Dirty Sea Ice Characteristics And Sources: The Role Of Anchor Ice, Dennis A. Darby, Wesley B. Myers, Martin Jakobsson, Ignatius Rigor
OES Faculty Publications
Extensive dirty ice patches with up to 7 kg m-2 sediment concentrations in layers of up to 10 cm thickness were encountered in 2005 and 2007 in numerous areas across the central Arctic. The Fe grain fingerprint determination of sources for these sampled dirty ice floes indicated both Russian and Canadian sources, with the latter dominating. The presence of benthic shells and sea weeds along with thick layers (2-10 cm) of sediment covering 5-10 m2 indicates an anchor ice entrainment origin as opposed to suspension freezing for some of these floes. The anchor ice origin might explain the …

Strain HIMB100 is a planktonic marine bacterium in the class Alphaproteobacteria. This strain is of interest because it is one of the first known isolates from a globally ubiquitous clade of marine bacteria known as SAR116 within the family Rhodospirillaceae. Here we describe preliminary features of the organism, together with the draft genome sequence and annotation. This is the second genome sequence of a member of the SAR116 clade. The 2,458,945 bp genome contains 2,334 protein-coding and 42 RNA gene

The prevailing paradigm of abrupt climate change holds that rapid shifts associated with the most extreme climate swings of the last glacial cycle were forced by changes in the strength and northward extension of Atlantic Meridional Overturning Circulation (AMOC), resulting in an abrupt reorganization of atmospheric circulation patterns with global teleconnections. To determine the timing of tropical Atlantic atmospheric circulation changes over the past 21 ka BP, we reconstruct high resolution sea surface temperature and δ18OSW (a proxy for surface salinity) records based on Mg/Ca ratios and oxygen isotope measurements in the planktonic foraminifera Globigerinoides ruber from …
