Extreme wave height estimation for ocean engineering applications in the Gulf of Mexico
(2012-07-16)
Recent hurricanes in the Gulf of Mexico (e.g., Ivan, Dennis, Katrina, Rita and Ike) were observed to develop wave conditions that were near or exceeded the predicted 100-year conditions. As a result, many offshore facilities, ...
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 ...
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 ...
Standing Stocks and Faunal Zonation of Deep-Sea Benthos: Patterns and Predictions across Scales
(2012-07-16)
The deep ocean (> 200-m depth) covers more than 65 percent of earth's surface and is known as the largest active carbon sink of the planet. Photosynthesis fixes inorganic carbon into organic rich-compounds to fuel the ...
Factors Shaping Macrofaunal Polychaete Communities in the Gulf of Mexico
(2013-04-23)
This dissertation addresses large-scale trends in composition, density, taxonomic and functional diversity in deep-sea benthic polychaete communities in the Gulf of Mexico (GoM). The study includes samples from two major ...
Water-Column Inertial and Sub-Inertial Oceanic Response to Hurricane Isaac in the Deepwater Gulf of Mexico
(2014-11-14)
Tropical Storm Isaac entered the Gulf of Mexico on 27 August 2012 and strengthened to become a Category 1 hurricane shortly before making landfall in southern Louisiana. Hurricane Isaac approached Southwest Pass near the ...
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 ...
Mercury Contamination in Pelagic Fishes of the Gulf of Mexico
(2012-10-19)
Knowledge of mercury concentrations in fish is essential for human health protection. Mercury is a naturally occurring element that acts as a neurotoxin to humans and other species. The biologically available mercury form, ...
The Distribution and Abundance of Bluntnose Flyingfish (Prognichthys occidentalis) Across the Gulf of Mexico
(2014-06-03)
Flyingfishes are an essential component of pelagic food webs, serving as both predator and prey. Many pelagic fishes (billfishes, dolphinfishes, and tunas) consume large quantities of flyingfish, and several studies have ...
Impacts of Vessel Noise Perturbations on the Resident Sperm Whale Population in the Gulf of Mexico
(2012-07-16)
The Gulf of Mexico is home to two of the world?s ten busiest ports by cargo volume, the Port of New Orleans and the Port of Houston; and in 2008, these ports hosted a combined 14,000 ships, a number which is likely only ...
