Investigating Environmental Change Due To Hypoxic Conditions On The Louisiana Continental Shelf: A Geochemical Approach
The Louisiana (LA) shelf is chronically affected by seasonal hypoxia that has been shown to be spatially expanding and growing progressively more severe. Hypoxic conditions on the shelf have been closely linked to the large quantities of nutrients delivered to the Gulf of Mexico via the Mississippi …

The Use of Computed Tomography to Measure Biogenic Structures in Recently Hypoxic and Normoxic Sediments on the Louisiana Continental Shelf
… response to hypoxic stress, the seafloor on the continental shelf of Louisiana was analyzed during the spring and fall of 2009 at four provinces of similar sediment type that differ in recent history of bottom water oxygen concentration. Subcores were analyzed by computed tomography (CT) to …

Framework and Evolution of a Transgressed Delta Lobe: The St. Bernard Shoals, Gulf of Mexico
Four modern shoals on the Louisiana continental shelf are proposed to have formed through transgression, marine reworking, and submergence of Mississippi River deltaic lobes. However, one of these shoals, the St. Bernard Shoals, is dissimilar to the other shoals in morphology and stratigraphy. …

Three-dimensional seismic interpretations of Miocene strata in Vermilion and South Marsh Island areas, Gulf of Mexico
The Louisiana continental shelf is the most prolific offshore hydrocarbon province in the nation. Siliciclastic Miocene strata in south Louisiana and the northern Gulf of Mexico continental shelf is the most productive chronostratigraphic unit accounting for 40% of the hydrocarbons produced in the …

Assessment of oxygen sources and sinks in the northern Gulf of Mexico using stable oxygen isotopes
… 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 influences both biological and physical …

Reef fish demographics on Louisiana artificial reefs : the effects of reef size on biomass distribution and foraging dynamics
… added a significant amount of structure to the Louisiana continental shelf, creating the largest de facto artificial reef deployment area in the world. Noting their usefulness as fish habitat, the Louisiana Artificial Reef Program was established to convert decommissioned platforms into …
