Marine geology and geophysics of the western South Orkney Plateau, Antarctica: Implications for Quaternary glacial history, tectonics, and paleoceanography
(1988)
Piston cores and single-channel seismic profiles were collected from the western South Orkney Plateau to investigate glacial history, survey the seismic stratigraphy, and test the feasibility of paleoceanographic interpretation as a site survey for O.D.P Leg 113 drilling operations. Data reveal evidence for past grounded ice to 240 meters depth, and ...
Sediment gravity transport on the Weddell Sea continental margin
(1980)
Understanding sediment gravity transport and continental slope processes has become increasingly important, especially with the current emphasis upon oil and gas exploration in the deep marine environment. Core x-radiography and textural and mineralogic analysis of sediment samples from Weddell Sea piston cores has enabled identification of several ...
Glacial marine sedimentation in the Weddell Sector of the East Antarctic Rise
(1981)
Seventeen cores were taken by John Anderson and Dennis Kurtz along two shelf-to-rise transects in the northeastern Weddell Sea during January-February 1978 as part of Islas Orcadas cruise 1578. These cores were examined by Wright (198) for mass flow characteristics and by Harlan for paleooceanography. The initial study showed that both shelf cores ...
Retreat history of the last glacial maximum ice sheet in Ross Sea, Antarctica
(1999)
High-resolution geophysical and geologic data were acquired in western and central Ross Sea, Antarctica, to determine the: (1) maximum extent and configuration of the ice sheet during the Last Glacial Maximum (LGM); (2) conditions and processes at the base of the expanded ice sheet and their role in ice stream activity; and (3) relative retreat history ...
A petrologic study of Weddell Sea sediments: implications for provenance and glacial history
(1984)
Knowledge of subglacial geology in Antarctica is restricted due to limited outcrop exposure. Investigations of terrestrially derived sediments deposited on the Antarctic continental margin have proved successful for gaining increased understanding of this ice-covered continent. Petrologic analyses conducted on glacial, glacial marine, and sediment ...
Seismic facies analysis and depositional history of an incised valley system, Galveston Bay area, Texas
(1991)
The history of the incised river valley underlying Galveston Bay was determined by examining the distribution of depositional units and the relationships between them. Initial incision of the valley occurred after the previous interglacial stage 5, substage 5e sea level highstand (120 ka, +6m relative to today). Fluvial terraces, present within the ...
Distribution and ecology of recent benthonic foraminifera of the Dumont D'Urville Sea, Antarctica
(1981)
Six distinct benthonic foraminiferal assemblages are recognized in the Dumont D'Urville Sea of Antarctica on the basis of the common occurrence and predominance of taxons. The distribution of calcareous and arenaceous faunal facies on the continental shelf coincides remarkably with the relative distribution of reworked glacial sediments and organic-rich ...
The composition and geologic setting of mare deposits on the far side of the moon
(1998)
The Clementine Mission acquired the first global compositional data for the Moon. Five discrete wavelengths (415, 750, 900, 950, 1000 nm) span the ultraviolet-visible spectrum. Using this data, I have performed a systematic study of the mare deposits on the far side of the Moon, between 80' east and 80' west longitude.
The major study areas are the ...
Seismic-stratigraphic analysis of shelf-margin delta/slope fan and basin floor fan on high-latitude and middle-latitude margins (Ross Sea, Weddell Sea and Alabama/West Florida shelf): Paleoclimatic and eustatic implications
(1998)
This dissertation consists of three chapters describing seismic stratigraphic studies in three very different continental margin settings. The first chapter discusses the northwestern Ross Sea, the second discusses the southeastern Weddell Sea and the third discusses the Alabama/west Florida margin. The purpose was to investigate stratigraphic ...
Sediments and sedimentary processes in Lake Houston, Texas
(1984)
Lake Houston is a man-made reservoir located northeast of Houston, Texas. The purpose of this investigation was to determine the nature of sediments and sedimentary processes in the lake. Cores were collected throughout the lake and sediment traps placed in strategic locations to collect suspended sediments. Samples were analyzed for grain-size, ...
