(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 ...
-
(Texas A&M University, 2005-02-17)A hull-mounted 38-kHz phased-array acoustic Doppler current profiler (ADCP) was used to acoustically survey the continental margin of the northern Gulf of Mexico (GOM) during 6 cruises in 2002-2003. This is the first ...
-
(1997)Diatoms (marine algae) are the largest contributor of biological productivity in the Antarctic. As the siliceous diatoms die their tests begin to accumulate on the sea floor, and preserve a record of how environmental ...
-
(2022-04-14)Decadal variations of the Atlantic meridional overturning circulation (AMOC) play a key role in decadal climate predictions. Previous studies suggest that forced ocean — sea-ice (FOSI) model simulations, which can represent ...
-
(2012-07-09)High-resolution seismic data from lower slope basins of Bryant Canyon suggest the recent occurrence of thin mud flows events, which influence the physical properties of the shallow sediments of Kaskida Minibasin. Therefore ...
-
(2023-05-02)Tropical cyclones (TCs) are dangerous weather events that cause significant damage to infrastructure and loss of life each year. TC track forecasting has improved considerably in recent decades, though improvements to ...
-
(Texas A&M University, 2005-08-29)The purpose of this study is to examine the sediment stratigraphy and oyster reefs of Lavaca Bay. There has been little previous research on the bay??s stratigraphy, and information from this study is important for industry ...
-
(2022-01-04)The dissertation seeks to elucidate the interaction of Amazon Plume Barrier Layer (BL) with hurricanes using a combination of observational analysis and high-resolution regional coupled model simulations. Firstly, multiple ...
-
(2009-05-15)In five summer cruises during the period 2000-2004, seventy-four box cores were collected from eleven locations from the Mississippi Canyon (480- 2750m, northern Gulf of Mexico), and an adjacent transect (336-2920) to ...
-
(2022-07-22)Observations of dissolved oxygen, salinity, temperature, and six different nutrient concentrations of the waters on the TXLA Shelf in the months of March – September in 2003 – 2014 were used in unsupervised and supervised ...
-
(2023-05-03)This study focuses on the recent history of environmental change within Sulaibikhat Bay, a 43 km², arid, urbanized embayment located along the southern shore of Kuwait Bay. Using the sedimentary record of down core changes ...
-
(2022-07-29)As an integral component of the Earth system, the exchange of momentum at air-sea interface plays an important role in connecting the ocean and atmosphere. Thus, the parameterization for air-sea fluxes is essential for ...
-
(1997)Three tows were taken at Galveston Bay, Tx on November 3rd and 4th, 1996 and were evaluated for abundance, with respect to the physical parameters: salinity, temperature, tide stage, and diel stage. These tows yielded a ...
-
(2012-10-19)Observations of Antarctic sea ice thickness are sporadic in space and time, hindering knowledge of its variability. A proxy based on stage of development data from the National Ice Center (NIC) weekly operational charts ...
-
(2016-04-29)Interannual variability in the Eastern Equatorial Pacific Ocean is explored using a high resolution ocean model. The model domain covers the coast of South America to 96°W, including the Galapagos Islands, and from 15°S ...
-
Analysis of Upwelling Changes in the Eastern Equatorial Pacific during El Niño Southern Oscillation (2012-02-14)The ocean reanalysis Simple Ocean Data Assimilation (SODA) 2.2.4 is used to explore the changes in upwelling from normal conditions to either El Nino or La Nina conditions. Physical and thermodynamic variables from the ...
-
(2015-05-05)A 56-member ensemble of ocean reanalyses is used to explore strong El Niño events in two 5-year periods, 1916 to 1920 and 1996 to 2000, that have markedly different quantities of observations. To generate the 56 forcing ...
-
(2021-03-22)Lacustrine varved sediments are high-resolution paleoenvironmental archives, in which their layers function as temporal markers of seasonality. The temporal framework of such records is required to improve benchmark climate ...
-
(2012-08-16)The Antarctic Circumpolar Current (ACC) is well known for its multiple bands with large meridional property gradients in the upper waters, each associated with a deep-reaching current core. A revised nineteen-year time ...
-
(2009-05-15)Galveston Island, Texas has been experiencing high rates of erosion in recent years, spawning an interest in developing complex beach management programs. However, before any effective management project can be implemented ...
