Growth Characterization of Mesophotic Rhodoliths in the Northern Gulf of Mexico Using Radiocarbon Dating
… from the intertidal zone to the lower limits of the photic zone. While growth rates and patterns in rhodoliths from shallower depths and simpler morphologies have been assessed using incremental and geochemical analyses, rhodoliths from mesophotic depths have rarely been studied. Furthermore, …

Trophic Ecology of Mesopelagic Fish Larvae and Juveniles in the Northern Gulf of Mexico
… waters below 200 m depth, and comprises 90% of the volume of the Gulf of Mexico. Deep-pelagic fishes are important prey for many oceanic consumers, but relatively little is known about their early life history, including larval fish trophic ecology. An understanding of the role deep-pelagic …

The Effect of Historic Shipwrecks on Sediment Microbiomes in the Northern Gulf of Mexico
… habitats, but it is the environmental conditions of a habitat that determine which microorganisms can thrive in terms of abundance or metabolic activity. Habitats that experience consistent physical and chemical environmental conditions repeatedly favor specific taxonomic groups which may result …

Distribution, Abundance, and Trophic Ecology of Anguilliform Leptocephali in the Northern Gulf of Mexico
<p>All species of anguilliform eels have pelagic leptocephalus larval stages, which provides a means of monitoring the population dynamics of these otherwise cryptic and hard to study species. The goals of this study were to: 1) describe the distribution and abundance of anguilliform eel …

Smectite/Illite Distribution and Diagenesis in the South Timbalier Area, Northern Gulf of Mexico
… for understanding the geological history of the Gulf of Mexico Basin, but few studies document any subsurface clay mineral distribution in the Gulf of Mexico. Shale samples from nine wells (30 samples) in the South Timbalier protraction were selected near known paleontological markers …

Organic geochemistry of an oil and gas seep in northern Gulf of Mexico sediments
… an extensive geochemical and geophysical survey of the outer slope of the northwestern Gulf of Mexico nine piston cores were recovered which had visible liquid organic deposits. In three of the cores deposits were observed concentrated in oblique fracture planes. Other occurrences included large …

Factors Affecting Short-term Oxygen Variability in the Northern Gulf of Mexico Hypoxic Zone
<p>Open-water continuous monitoring of DO concentrations at a single station (C6) in the Gulf of Mexico from 1989 to 2008 afforded an excellent opportunity to characterize short-term oxygen variability and to estimate the relative importance of key physical and biological factors controlling the …

Movement Ecology and Trophic Dynamics in the northern Gulf of Mexico: Implications for Fisheries Management
<p>The northern Gulf of Mexico (nGOM) is a diverse and productive region for living marine resources. The region supports lucrative commercial and recreational fisheries ranging from low-trophic-level species, such as penaeid shrimps and forage fishes, to high-trophic-level predators (e.g. …

Ichthyoplankton Composition in the Loop Current and Sargassum Habitats in the Northern Gulf of Mexico
<p>Ichthyoplankton in the Gulf of Mexico (GOM) aggregate in two different habitats that serve to provide refuge and concentrate prey in an otherwise oligotrophic environment: the Loop Current (LC) a mesoscale oceanographic feature characterized by the transition of environmental conditions of the …

Fluid relationships in the Northern Gulf of Mexico using dissolved ion concentrations and strontium isotopes
Pore fluids from the slope in the Gulf of Mexico demonstrate specific ion enrichment and a range in concentration. Dissolved metal and halogen fluid concentrations and strontium isotope ratios from ten sites on the Gulf of Mexico (GoM) continental slope were compared to identify the variations in …

Fine-grained sedimentation on the Chenier Plain Coast and inner continental shelf, northern Gulf of Mexico
This thesis examines the evolution of a mud-dominated coastal sedimentary system on multiple time scales. Fine-grained systems exhibit different properties and behavior from sandy coasts, and have received relatively little research attention to date. Evidence is presented for shoreline accretion …

Pore size distribution and methane equilibrium conditions at Walker Ridge Block 313, northern Gulf of Mexico
… salinity and pore size may allow coexistence of three methane phases: liquid (L), gas (G), hydrate (H) in marine gas hydrate systems. A discrete zone of three-phase equilibrium may occur near the base of the gas hydrate stability zone (GHSZ) in sediments with salinity close to seawater due to …

Tidal hydrodynamic response to sea level rise and coastal geomorphology in the Northern Gulf of Mexico
… to affect coastal environments in a multitude of ways, including submergence, increased flooding, and increased shoreline erosion. Low-lying coastal environments such as the Northern Gulf of Mexico (NGOM) are particularly vulnerable to the effects of SLR, which may have serious consequences for …

Assessment of oxygen sources and sinks in the northern Gulf of Mexico using stable oxygen isotopes
… to these areas increase. The second largest zone of human-induced hypoxia is located on the Louisiana continental shelf where hypoxic bottom waters commonly occur during summertime. This region is strongly impacted by the large flux of freshwater and nutrients from the Mississippi River, which …

Tropical Cyclone Storm Surge Detection in Slash Pine Radial Growth along the Northern Gulf of Mexico Coastline
<p>My thesis examines the ecological impact of tropical cyclone (TCs) storm surge on coastal slash pine (<em>Pinus elliottii </em>var. <em>elliottii</em> Engelm) communities along the Gulf of Mexico in the southern United States (U.S.). Previous research has shown slash pine radial growth trends …

NEW INSIGHTS INTO THE PALEOVEGETATION OF THE ANCIENT UNDERWATER FOREST LOCATED IN THE NORTHERN GULF OF MEXICO
<p>A well-preserved remnant of an ancient bald cypress forest (hereafter, Underwater Forest) constitutes the only known archive of a glacial refuge on the once exposed continental shelf of the Northern Gulf of Mexico. This forest existed around 41-72 yBP (MIS 3-5) according to the existing dating …

GENETIC PARAMETERS FOR HEAT AND SALINITY STRESS TOLERANCE IN NORTHERN GULF OF MEXICO EASTERN OYSTER, CRASSOSTREA VIRGINICA
<p>Summer mortalities in Gulf of Mexico eastern oysters have been linked to excessively high temperatures, and chronic exposure to low salinity. In this study, the feasibility of improving tolerance to these two stresses by selection was evaluated in common garden experiments employing a pool of …

Assessing the Nursery-Role Function of Pelagic Sargassum for Juvenile Fishes in the Northern Gulf of Mexico
<p><em>Sargassum</em>, a genus of holopelagic brown algae, floats at the ocean’s surface using air-filled bladders and forms a complex comprised of two species, <em>S. natans</em> and<em> S. fluitans</em>. Oceanic processes (e.g., Langmuir circulation, etc.) aggregate <em>Sargassum </em>into mats …
