Seismic stratigraphy and structure of Prydz Bay, Antarctica: Implications from Leg 119 drilling Seismic stratigraphy and structure of Prydz Bay, Antarctica: Implications from Leg 119 drilling
Prydz Bay is situated on the MacRobertson Land coast of East Antarctica at the seaward end of a 700-km-long transverse rift zone, the Lambert Rift. New and reprocessed seismic reflection data are combined with drilling results from five Leg 119 sites across Prydz Bay to study the regional stratigraphy and structure of the continental shelf and upper slope. Severe seismic multiples hamper

Quaternary history of some southern and central Rocky Mountain basins Quaternary history of some southern and central Rocky Mountain basins
This chapter summarizes the current state of late Cenozoic stratigraphic knowledge in some Rocky Mountain basins (here defined as the structurally low portions of major drainage basins) that have been studied in detail since Scott’s (1965) summary on the nonglacial history of the southern and middle Rocky Mountains. The Quaternary history of few of these basins has been studied as...

Is the extent of glaciation limited by marine gas-hydrates? Is the extent of glaciation limited by marine gas-hydrates?
Methane may have been released to the atmosphere during the Quaternary from Arctic shelf gas-hydrates as a result of thermal decomposition caused by climatic warming and rising sea-level; this release of methane (a greenhouse gas) may represent a positive feedback on global warming [Revelle, 1983; Kvenvolden, 1988a; Nisbet, 1990]. We consider the response to sea-level changes by the...

High-energy carbonate-sand accumulation, the Quicksands, southwest Florida Keys High-energy carbonate-sand accumulation, the Quicksands, southwest Florida Keys
High-resolution seismic-reflection profiles of the Quicksands, located along a broad ridge on the platform shelf west of Key West, Florida, indicate a significant deposit of non-oolitic carbonate sand occurs in a belt 47 km long by 28 km wide. The surface of the belt is ornamented by large (5 m), migrating tidal bars, oriented in a north-south direction, on which sand waves, oriented in...

Imaging the midcontinent rift beneath Lake Superior using large aperture seismic data Imaging the midcontinent rift beneath Lake Superior using large aperture seismic data
We present a detailed velocity model across the 1.1 billion year old Midcontinent Rift System (MRS) in central Lake Superior. The model was derived primarily from onshore-offshore large-aperture seismic and gravity data. High velocities obtained within a highly reflective half-graben that was imaged on coincident seismic reflection data demonstrate the dominantly mafic composition of the...
