Polycyclic Aromatic Hydrocarbon Metabolites As A Biomarker Of Exposure To Oil In Demersal Fishes Following The Deepwater Horizon Blowout, Susan Susan Snyder

USF Tampa Graduate Theses and Dissertations

The Deepwater Horizon blowout occurred on April 20th, 2010, releasing 4.9 million barrels of Louisiana crude oil into the Gulf of Mexico (GoM). Subsequent to the Deepwater Horizon blowout, sediment cores revealed oil on the northern GoM seafloor and abnormal skin lesions were seen in GoM fishes. Exposure to polycyclic aromatic hydrocarbons (PAHs), a component of crude oil, in fish has been associated with many sublethal effects, including cancer and population-level effects. Using a biomarker of exposure to PAHs, this thesis evaluates inter-species, temporal and spatial differences in exposure to hydrocarbon contamination between three species of fish with varying levels …

Growth Rates In Gulf Of Mexico Red Snapper, Lutjanus Campechanus, Before And After The Deepwater Horizon Blowout, Elizabeth Shea Herdter

USF Tampa Graduate Theses and Dissertations

The Deepwater Horizon blowout occurred on April 20^th, 2010 and released nearly 5 million barrels of crude oil into the northern Gulf of Mexico causing pollution of the water and sediment inhabited by many fishes for at least 87 days while the wellhead went uncapped. Populations of the Gulf of Mexico Red snapper, Lutjanus campechanus, an important fish to the ecology and economy in the region, exhibit affinity to shallow water oil infrastructure such as the Deepwater Horizon making them especially vulnerable to crude oil contamination. The objective of this study is to determine growth of Red …

Use Of A Towed Camera System For Estimating Reef Fish Populations Densities On The West Florida Shelf, Sarah Elizabeth Grasty

USF Tampa Graduate Theses and Dissertations

Reef fish species tend to reside over high relief habitat which makes them difficult to sample with traditional gears such as nets and trawls. Therefore, implementing and understanding the strengths and weaknesses of new approaches which incorporate acoustic and optical methods has become a priority for reef fish stock assessment. Beginning in June of 2013, a towed camera system known as the Camera-Based Assessment Survey System (C-BASS) has been used to visualize over 500 kilometers of transect and record more than 80 hours of video over several habitats in the Gulf of Mexico. Surveys have been completed on the West …

Aptian To Santonian Foraminiferal Biostratigraphy And Paleoenvironmental Change In The Sverdrup Basin As Revealed At Glacier Fiord, Axel Heiberg Island, Canadian Arctic Archipelago, Claudia J. Schröder-Adams, Jens O. Herrle, Ashton F. Embry, James W. Haggart, Jennifer M. Galloway, Adam T. Pugh, David M. Harwood

ANDRILL Research and Publications

Exceptional exposures of a High Arctic Cretaceous sedimentary record were studied at Glacier Fiord, Axel Heiberg Island. The succession reveals a complex Aptian to Santonian paleoenvironmental history of the Sverdrup Basin that documents several global events. Foraminiferal faunas in combination with rare macrofossil occurrences permit the distinction of nine zones that facilitate biostratigraphic correlations to other High Arctic locales, the Beaufort Mackenzie Basin and the Western Interior Sea. The depositional environment as exposed in the Christopher, Hassel, Bastion Ridge and Kanguk formations changed frequently from a shelf to a shoreface setting. Most sequence boundaries appear to be conformable where shoaling …

Dynamics And Survival Of Coral And Octocoral Juveniles Following Disturbance On Patch Reefs Of The Florida Reef Tract, Lucy Bartlett

USF Tampa Graduate Theses and Dissertations

Over the past several decades, rapid decline in adult stony-coral (comprising the Orders Scleractinia and Anthomedusae, specifically Family Milleporidae) cover has occurred concurrent with an increase in adult octocoral (Octocorallia/gorgonian) cover along the Florida Reef Tract. In January 2010, the Florida Keys experienced extremely cold air and water temperatures, below the lethal threshold for many reef organisms including corals. Very high stony-coral mortality occurred on some patch reefs. The newly-available space created by this disturbance event provided the opportunity for recruitment and settlement of new coral larvae and other reef organisms.

The goal of this study was to examine post-disturbance …

Assessments Of Surface-Pelagic Drift Communities And Behavior Of Early Juvenile Sea Turtles In The Northern Gulf Of Mexico, Robert F. Hardy

USF Tampa Graduate Theses and Dissertations

Knowledge of species distribution and habitat associations are essential for conservation measures. Such information is lacking for many marine species due to their occupancy of broad and ephemeral habitats that are difficult to access for study. Sea turtles, specifically the surface-pelagic juvenile stage of some species, are a group for which significant knowledge gaps remain surrounding their distribution and habitat use. Recent research has confirmed the long-standing hypothesis that the surface-pelagic juvenile stage occurs within surface-pelagic drift communities (SPDC). Within the North Atlantic and surrounding basins, the holopelagic macroalgae Sargassum spp. dominates SPDC and serves as a remotely-detectable indicator of …

Iron Sources And Dissolved-Particulate Interactions In The Seawater Of The Western Equatorial Pacific, Iron Isotope Perspectives, M. Labatut, F. Lacan, C. Pradoux, J. Chmeleff, A. Radic, J. W. Murray, F. Poitrasson, Anne M. Johansen, F. Thil

All Faculty Scholarship for the College of the Sciences

This work presents iron isotope data in the western equatorial Pacific. Marine aerosols and top core margin sediments display a slightly heavy Fe isotopic composition (δ⁵⁶Fe) of 0.33 ± 0.11‰ (2SD) and 0.14 ± 0.07‰, respectively. Samples reflecting the influence of Papua New Guinea runoff (Sepik River and Rabaul volcano water) are characterized by crustal values. In seawater, Fe is mainly supplied in the particulate form and is found with a δ⁵⁶Fe between −0.49 and 0.34 ± 0.07‰. The particulate Fe seems to be brought mainly by runoff and transported across continental shelves and slopes. …

Predation Thresholds In Marine Microbial Communities Applied To Environments With Low Prey Abundances, Bonnie Bailey

OES Theses and Dissertations

Prokaryotes (Bacteria and Archaea) comprise the largest component of biomass in the world's oceans. Their abundances are controlled by resource availability, viral infections and protist grazing. Many pico- and nano-eukaryotic predators grow almost as quickly as their prey, and greatly increase in numbers as soon as their prey do, leading in tum to depletion in prokaryotes. It is still unclear however, as to what extent microbial predators are able to feed in low prey environments, most prominently in the largest biome on Earth, the deep sea (below l 000 m depth). It has been hypothesized that in low prey environments, …

Regional Differences In Quality Of Krill And Fish As Prey Along The Western Antarctic Peninsula, Kate E. Ruck, Deborah K. Steinberg, Elizabeth A. Canuel

VIMS Articles

The warming trend in the northern part of the Western Antarctic Peninsula (WAP) has led to a decrease in perennial and summer sea ice, an increase in heat content over the shelf, and lower phytoplankton biomass, which could affect the prey quality of krill and fish that are utilized by apex predators. We compared prey quality metrics, including elemental (C, N) content; total, neutral, and polar lipid content; and energy densities of known penguin prey items including krill (Euphausia superba, Thysanoessa macrura, and E. crystallorophias) and fish (silverfish Pleuragramma antarcticum and the myctophid Electrona antarctica) …

Microbial Community Assembly Found With Sponge Orange Band Disease In Xestospongia Muta (Giant Barrel Sponge), Rebecca Mulheron

HCNSO Student Theses and Dissertations

The giant barrel sponge, Xestospongia muta is an iconic and essential species of the coral reefs in South Florida. The sponge has primary roles providing ecosystem services and creating unique habitats for diverse microbial communities. On April 27, 2012 an outbreak of Sponge Orange Band Disease (SOB) was detected off the coast of South Florida. The disease begins with sponge bleaching, followed by mesohyl or “mesohyl” necrosis and often total mesohyl disintegration. Sampling from two diseased populations at Boynton Beach and Fort Lauderdale, FL took place on May 11th and May 29th, 2012. Each of the nine diseased sponges from …
