3-D multichannel seismic reflection study of variable-flux hydrocarbon seeps, continental slope, northern Gulf of Mexico
(Texas A&M University, 2004-11-15)In the northern Gulf of Mexico, seafloor hydrocarbon fluid and gas seepage is an ubiquitous process on the continental margin. Although seafloor seepage and seep-related features (mud volcanoes, carbonate formation) have ... -
Anticyclonic rings and the energetics of the circulation of the Gulf of Mexico
The question addressed in this dissertation is what is the primary energy source for the anticyclonic gyre found in the western Gulf of Mexico. Two energy sources are considered: the Loop Current through the mechanism of ... -
Aquatic macrophyte and animal communities in a recently restored brackish marsh: possible influences of restoration design and the invasive plant species Myriophyllum spicatum
(2012-07-16)The numerous benefits that wetlands provide make them essential to ecosystem services and ecological functions. Historically, wetland losses have been caused by natural and anthropogenic changes. In Texas, nearly 50% of ... -
Assessment of estuarine habitats for resident and estuarine-dependent species: tools for conservation and management
(2009-05-15)My research in coastal Ecuador and the northern Gulf of Mexico (GOM) elucidated differences in value of shallow estuarine habitats for fishes and invertebrates. I focused on mangrove and tidal river habitats in Ecuador, ... -
Assessment of seismic risk for subsea production systems in the Gulf of Mexico
(Texas A&M University, 2004-09-30)The number of subsea production systems placed in deepwater locations in the Gulf of Mexico (GOM) has increased significantly in the last ten to fifteen years. Currently, API-RP2A (2000 a,b) designates the GOM as a low ... -
ASSOCIATION BETWEEN SHRIMP CATCH PER UNIT EFFORT AND ENVIRONMENTAL VARIABLES IN THE GULF OF MEXICO
(2013-02-04)The commercial shrimp harvest is the second most important fishery in the United States, and eighty percent of this harvest by weight is caught in the Gulf of Mexico (GOM). Survival rate in the post larval stage in GOM ... -
Bioaccumulation of mercury in pelagic fishes in NW Gulf of Mexico
(Texas A&M University, 2006-08-16)Total mercury (Hg) levels were determined in the tissues of ten taxa of pelagic fishes, with a special emphasis on apex predators (large vertebrates). Highest Hg levels were observed in blue marlin (Makaira nigricans), ... -
Biodiversity of Pelagic Ichthyoplankton in the Northern Gulf of Mexico
(2018-12-05)Studies on larvae and juvenile fishes during the first few months of life are limited for many pelagic species despite the fact that biological data on these stages are needed to better assess and monitor recruitment ... -
Calcium Carbonate Saturation Horizons in the Gulf of Mexico
(2017-06-05)The calcium carbonate saturation state is decreasing globally in the surface waters due to the increase in carbon dioxide in the atmosphere and dissolved carbon dioxide in the oceans. Recent evidence suggests that the ... -
Centennial-Scale Sea Surface Temperature and Salinity Variability in the Florida Straits During the Early Holocene
(2012-10-19)Previous studies showed that sea surface salinity (SSS) in the Florida Straits as well as Florida Current transport covaried with changes in North Atlantic climate over the past two millennia. However, little is known about ... -
Characteristics of the deep scattering layer in the Gulf of Mexico as they relate to sperm whale diving and foraging behavior
(2009-05-15)This research was carried out in support of fieldwork in the Gulf of Mexico in summers 2004 and 2005 as part of the multidisciplinary Sperm Whale Seismic Study (SWSS). Important aspects of SWSS research include oceanographic ... -
Characterizing the Weather Band Variability of the Texas Coastal Current
(2014-07-17)Current velocities from 21 years (1992-2012) of near-continuous observations are used to investigate the Texas Coastal Current on the western Texas-Louisiana continental shelf in the northwestern Gulf of Mexico. Observations ... -
Coastal and Marine Nitrogen Sources Shift Isotopic Baselines in Pelagic Food Webs of the Gulf of Mexico
(2012-07-16)Upwelling, atmospheric nitrogen (N2) fixation by cyanobacteria, and freshwater inputs from the Mississippi River system have been shown to stimulate new production by alleviating nitrogen (N) limitation in the northern ... -
Coastal Hypoxia on the Texas Shelf: An Ocean Observing and Management Approach to Improving Gulf of Mexico Hypoxia Monitoring
(2013-05-07)A combination of in situ sampling and real-time ocean observations was used to investigate the processes responsible for the formation and the areal extent of Texas coastal hypoxia from 2002 to 2011. In situ sampling, ... -
Commercial Fishing Occupational Safety and Health in the Gulf and Agricultural Occupational Safety and Health in Graduate Medical Education
(2018-06-19)Background–The commercial fishing work sector continues to experience one of the highest occupational fatality rates in the U.S. There are regional differences in distribution of these events relative to fishery type, ... -

(2018-06-19)Background–The commercial fishing work sector continues to experience one of the highest occupational fatality rates in the U.S. There are regional differences in distribution of these events relative to fishery type, ... -
Commercial Shrimp Production in the Northern Gulf of Mexico: Effects of Shrimp Habitat on Commercial Shrimp Fishery Catch
(2019-05-16)The Gulf of Mexico penaeid shrimp fishery is perennially one of the most productive fisheries in the southeast United States in terms of landings and value. Since 2007, a mandatory fishery observer program has been collecting ... -
Community structure of deep-sea bivalve mollusks from the northern Gulf of Mexico
(Texas A&M University, 2004-09-30)Density, species diversity, species richness, and evenness of bivalve mollusks were measured in the deep (0.2km to 3.7km) northern Gulf of Mexico to describe the community structure of benthic bivalve mollusks. Density ... -
Constraining Pore Pressure Prediction Using Seismic Inversion
(2016-04-26)This paper addresses utilizing borehole acoustic logs to predict pore pressure at the borehole and employing seismic inversion to extrapolate these predictions. We implemented common approaches with our proposed quality ... -
The contribution of mangrove expansion to salt marsh loss on the Texas Gulf coast
(PLOS, 2015-05-06)Landscape-level shifts in plant species distribution and abundance can fundamentally change the ecology of an ecosystem. Such shifts are occurring within mangrove-marsh ecotones, where over the last few decades, relatively ...
