Structural and Stratigraphic Reconstruction of the Whiting Dome Salt Structure in Viosca Knoll-Mississippi Canyon, GOM, Using 3D Seismic Data
<p>Understanding the complexities of salt tectonics is one of the most important factors regarding seismic interpretation of stratigraphy, structure, and geomorphology in the Gulf of Mexico. Evaluating the processes affecting recent mobilization of salt in the shallow, well-imaged section can help …

Mesozoic Rift Evolution and Crustal Structure of the Gulf of Mexico Basin from Integration of Multiple Geological and Geophysical Datasets
The Gulf of Mexico basin (GOM) is one of the most prolific, hydrocarbon-producing basins in the world. However, our understanding of the Triassic-Jurassic rift history and crustal structure of the GOM is limited. This dissertation integrates satellite free-air gravity data, full-tensor gravity …

Cyclic response of Gulf of Mexico clay from the Walker Ridge
… laboratory and in-situ tests on Gulf of Mexico (GOM) clay from the Walker Ridge to draw insights on the cyclic response of soft clays in general. The main objectives of this research were to (1) characterize GOM clay in terms of its index properties, compressibility and monotonic shear behavior, …

Factors Shaping Macrofaunal Polychaete Communities in the Gulf of Mexico
… polychaete communities in the Gulf of Mexico (GoM). The study includes samples from two major sampling programs: the Deep Gulf of Mexico Benthos (DGoMB) program (2000?2002) (51 stations, 200-3700 m) and the SIGSBEE program (Universidad Nacional Aut?noma de M?xico), 2008-2010 (27 stations on the …

The influence of salinity on the mechanical behavior of high plasticity soils
… carried out on Gulf of Mexico - Eugene Island (GOM EI). This material was used to examine the behavior of a soil whose fabric has been changed by the removal of the natural salts via leaching. Both leached and natural GOM El were tested to investigate the influence of salinity on strength …

Physical controls on copepod aggregations in the Gulf of Maine
… role that the circulation in the Gulf of Maine (GOM) plays in determining the distribution of dense aggregations of copepods. These aggregations are an important part of the marine ecosystem, especially for endangered North Atlantic right whales. Certain ocean processes may generate dense copepod …

Life History of the Southern Kingfish, <i>Menticirrhus americanus</i>, from the North-Central Gulf of Mexico
… sciaenid along the north-central Gulf of Mexico (GOM), but annual harvest has declined over the last decade. Little is known about the life history of southern kingfish in the north-central GOM, and thus the objectives of this study are to establish the spawning season, spawning frequency, …

Compression behavior of smectitic vs. illitic mudrocks
… The original Gulf of Mexico - Eugene Island (GoM-EI) mudrock sets the baseline for smectitic mudrock in order to compare with illitic mudrocks. Two methods were used to create illitic mudrock from the GoM-EI sediment.

Atmospheric Mercury Species In Northern Mississippi: Concentrations, Sources, Temporal Patterns, And Soil-Air Exchange
… mercury (gem), gaseous oxidized mercury (gom), and particulate-bound mercury (pbm), along with meteorological parameters and other ancillary data, were collected for more than a year in Oxford, Mississippi. Mean levels of gem were 1.54 â± 0.32 ng∙m<super>-3</super> and were lower and more …

Microbial carbon sources on the shelf and slope of the northwestern Gulf of Mexico
… abyssal plain sediments of the Gulf of Mexico (GOM). Previous reports using the Laguna Madre data as examples, have been used to make comparisons of PLFA 16:0 and PLFA 15:0 isotope ratios and PLFA 16:0 and total organic carbon isotope ratios. Deviations from the 1:1 line in the former indicate …

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 …

A 20,000 year flowstone record of Gulf of Mexico sourced moisture in Texas
… the contribution of either Gulf of Mexico (GoM) or Pacific Ocean sourced moisture since the Last Glacial Maximum (LGM) at cave sites across the Southwest. In this study, a new oxygen isotope time series is developed from a flowstone in central Texas as a means to test this hypothesis. Due to …

Age, Growth, Mortality, and the Effects of Trawling on Mortality of the Longspine Porgy, <i>Stenotomus caprinus</i>
… trawl fisheries in the northern Gulf of Mexico (GOM). Biological data of length, weight, and abundance have been collected since 1972 on the Southeast Area Monitoring and Assessment Program (SEAMAP) surveys with a variety of GOM species, including Longspine Porgy, using trawl nets during …

Tectonic Setting, Structure, and Seismic Stratigraphy of the Apalachicola Rift and its Overlying Sag Basin in the Northeastern Gulf of Mexico
… rift (AR) in the northeastern Gulf of Mexico (GOM) is a ~220-km- long half-graben that contains 5-8 km of undrilled, syn-rift clastic deposits inferred to be of late Triassic-early Jurassic age. Previous workers have interpreted pre-salt (Triassic-early Jurassic), basinward-dipping, seismic …

A Geological Interpretation of 3D Seismic Data of a Salt Structure and Subsalt Horizons in the Mississippi Canyon Subdivision of the Gulf of Mexico
<p>The Gulf of Mexico (GOM) represents a challenge for exploration and production. Most of the sediments coming from North America has bypassed the shelf margin into Deep Water. In an Attempt to attack this challenge this thesis pretends to break the GOM's false bottom, mainly comprised by diverse …
