(Texas A&M University. Libraries, 1976)This research was a detailed study of the clay fabrics and selected geotechnical properties of cored submarine sediment sampled to depths of 150 m from the Mississippi Prodelta depositional environment. The clay fabric ...
-
(Texas A&M University. Libraries, 1981)The research presented herein is a new design and development of a special methodology to delineate the nature of clay fabric in natural sediments under in situ downhole pressure conditions using pressurized core barrel ...
-
(Texas A&M University. Libraries, 1986)The West Flower Garden Bank is a coral reef on the Texas continental shelf. The corals on the bank are vulnerable to sediment contamination and to excess turbidity in the overlying water column. Concern for the environmental ...
-
(Texas A&M University. Libraries, 1981)Since Broecker's (1965) original work, extensive studies have been made on abyssal near-bottom water mixing processes using the radioactive parent-daughter pair radium-226 (Ra) - radon-222 (Rn). One assumption critical to ...
-
(Texas A&M University. Libraries, 1977)Pore water Fe and Mn were measured in a suite of gravity cores from the northern Gulf of Mexico in a study of diagnostic remobilization in recent sediments. Other relevant parameters such as pH, oxidation potential, total ...
-
(Texas A&M University. Libraries, 1983)The Orca Basin is a depression on the continental slope of the northern Gulf of Mexico which is partially filled with anoxic hypersaline brine. Steady-state diagenetic modelling of sulfate reduction in the basin sediments ...
-
(Texas A&M University. Libraries, 1989)Periplatform sediments from the slopes north of little Bahama Bank and Exuma Sound were studied extensively for use as a model for sediments in other similar environments within the upper 50 to 150 meters below the seafloor ...
-
(Texas A&M University. Libraries, 1981)Geotechnical property analyses on sediments recovered by DSDP drilling on select convergent margins were integrated to determine the variability in these properties along the lower trench inner slope and to delineate the ...
-
(Texas A&M University. Libraries, 1970)This investigation of consolidation-induced changes in macrostructures is based on (1) the use of stereo X-ray radiography to map the macrostructures prior to and following consolidation and (2) a comparison of changes ...
-
(Texas A&M University. Libraries, 1976)Very weak marine clay sediments may be subjected during storms to considerable movement. A theoretical procedure is developed to determine the loads that the moving sediments exert on pile foundations. The lateral loading ...
-
(Texas A&M University. Libraries, 1978)Concentrations of the C₁-C₃ hydrocarbons and stable carbon isotope compositions of methane in recent sediments and seep gases of the Texas-Louisiana shelf-slop region were determined. These gases have been produced by both ...
-
(Texas A&M University. Libraries, 1987)The sediment geochemistry of Mn at a site in Galveston Bay, Texas, was investigated through a three-fold approach. A field study demonstrated that despite the coarse, quartz-rich nature of the bottom sediments, Mn was ...
-
(Texas A&M University. Libraries, 1986)Late Pleistocene to Middle Miocene turbidite sands (0 to 900 m depth below seafloor) from Deep Sea Drilling Project (DSDP) Leg 10 Sites 85, 90, and 91 have an average framework, grain composition of 30% quartz, 25% feldspar, ...

(Texas A&M University. Libraries, 1988)
-
(Texas A&M University. Libraries, 1984)Two distinct sedimentary sections were drilled by the Deep Sea Drilling Project using the hydraulic piston core, and were subjected to geotechnical testing in an effort to document the physical changes related to sediment ...
-
(Texas A&M University. Libraries, 1980)Dredged sediments from the Gulf Intracoastal Waterway near Galveston, Texas were used as a substrate in the construction of an artificial marsh. Substrate chemical and physical properties (total Kjeldahl nitrogen, ammonium, ...
-
(Texas A&M University. Libraries, 1991)Physical properties measurements and geotechnical testing of Ocean Drilling Program Leg 134 cores from the d'Entrecasteaux Zone (DEZ) and the intra-arc North Aoba Basin (NAB) in the southwest Pacific Ocean provide a ...
-
(Texas A&M University. Libraries, 1978)This study was designed to determine the possibility of utilizing physical properties as a tool to interpret portions of the geologic history of the west African continental margin. The properties measured were: bulk ...
-
(Texas A&M University. Libraries, 1971)The removal of dissolved organic compounds and carbon dioxide from sea water by sedimentary minerals and the subsequent incorporation of both in sedimentary deposits are determined by various environmental factors. The ...
-
(Texas A&M University. Libraries, 1984)The Late Pleistocene sediments in the deep basin of the Gulf of Mexico are marked by several episodes of the preservation of aragonitic pteropods. Pteropods are not preserved on the sea floor of the abyssal Gulf today nor ...
