Micro-phytoplankton variability at the equatorial Pacific (140W̊) during the JGOFS EQPAC Time Series Studies 1992
(Texas A&M University, 1994)
Micro-phytoplankton (>20 gm cell size) was sampled in the upper 200 m of the water column at the Pacific equator, 140'W, during two JGOFS EqPac Time Series Studies, in order to determine the changes in the micro-phytoplanlcton ...
Seismic stratigraphy and salt tectonics of the Alaminos Canyon area, Gulf of Mexico.
(Texas A&M University, 1994)
The Alaminos Canyon region is located at the change in the bathymetric trend between the slope and rise. Over 6,435 km of migrated seismic reflection profiles were analyzed to produce two structure and two isopach maps. ...
Investigations on the sediment chronology and trace metal accumulation in Sabine-Neches estuary, Beaumont, Texas
(Texas A&M University, 1994)
The accumulation rates of sediments and trace metals (Co, Cr, Cu, Ni, Pb, Zn) were measured along with the concentrations of Al, Fe, Mn and organic carbon in four sediment cores from Sabine-Neches estuary, near Beaumont, ...
Late Pleistocene to Recent sediment transport pathways of the Green Canyon OCS area, northern Gulf of Mexico
(Texas A&M University, 1994)
This study addresses some of the complexities of sediment transport systems on the continental slope of the Green Canyon OCS area south of the Louisiana coast. Five Late Pleistocene to Recent sedimentary sequences are ...
Phytoplankton distributions across the Texas-Louisiana shelf in relation to coastal physical processes
(Texas A&M University, 1994)
The relationships between phytoplankton pigment distributions and coastal physical processes were investigated as part of the Texas-Louisiana Shelf Circulation and Transport Processes Study (LATEX A). Surface to bottom ...
The distribution and ecology of benthic Foraminifera and associated meiofauna in the Northeast Water Polynya, Greenland
(Texas A&M University, 1994)
Abundance of living calcareous Foraminifera and associated meiofauna have been estimated from the Northeast Water Polynya. Calcareous forams (] 150 gm) represented on average 28 and 47 % of the abundance and biomass ...
Biological characteristics of Uphausia superba dan in acoustically detected aggregations near Elephant Island, Antarctica
(Texas A&M University, 1994)
Euphausia superba aggregations were sampled with a Multiple Opening/Closing Net and Environmental Sensor System (MOCNESS) during the austral summer 1991-92 Antarctic Marine Living Resources (AMLR) survey in the vicinity ...
Biomarkers of polycyclic aromatic hydrocarbon (PAH) exposure in northwest Gulf of Mexico marine fish and invertebrates: indicators of offshore petroleum contamination
(Texas A&M University, 1994)
Higher molecular weight Polycyclic aromatic hydrocarbons (PAHS) associated with crude oil induce CYPIAI gene expression, and this response has been utilized as a biomarker of exposure to PAHs in aquatic and marine environments. ...
Stable carbon isotopes as an indicator of petroleum biodegradation in estuarine sediments
(Texas A&M University, 1994)
An investigation into the use of stable carbon isotopes (513C) as tracers of biodegradation of petroleum in estuarine sediments was performed. This technique uses the 813C of respired C02 as an indicator of the organic ...
Spatial trends in community and health-related characteristics of Galveston Bay oyster reefs
(Texas A&M University, 1994)
The spatial trends in the oyster community and healthrelated variables for Galveston Bay oyster reefs indicated that some other factors in addition to salinity are major structuring forces. Three different directional ...
