The continental margin off northeast Australia, comprising the Great Barrier Reef (GBR) platform and Queensland Trough, is the largest tropical mixed siliciclastic /carbonate depositional system in existence. We describe a suite of 35 piston cores and two Ocean Drilling Program (ODP) sites from a 130 × 240 km rectangular area of the Queensland Trough, the slope and basin setting east of the cen...

An integrated study using 3D seismic, wireline logs, and core analyses was conducted to establish strategies for exploring in compartmentalized, lowstand, prograding, deltaic systems. Frio sediments, averaging ~11,000 ft, are commercial gas reservoirs in several of the growth-faulted, intraslope subbasins in South Texas. These exploitation targets are typically located in faultbounded compartme...

Reef ecosystems built during successive periods of Pleistocene sea level rise have shown remarkable persistence in coral community structure, but little is known of the ecological characteristics of reef communities during periods of low sea stands or sea level falls. We sampled the relative species abundance of coral, benthic foraminifera, and calcareous red algae communities from eight submer...

Architecture of slopeand basin-floor-fan systems in growth-faulted subbasins along the south Texas Gulf Coast developed as a result of interplay between synsedimentary tectonics and sedimentation during third-order sea-level lowstands. These subbasins, or intraslope basins, have not been adequately explored for their slope and basin-floor-fan potential, as have the intraslope basins in salt-dom...

Atokan-age units in the Permian Basin record a 2-order transgression, with aerially restricted, lower Atokan fluvial to shallow-marine siliciclastics followed by pervasive carbonate deposition. In general, Atokan-age siliciclastics dominated deposition in the west of the Permian Basin while carbonate deposition dominated throughout the rest of the basin. Predominance of carbonate facies across ...

The lowstand extensions of two fluvial systems from the Cascadia subduction margin are investigated using high-resolution seismic reflection data to determine relative controls on paleodrainage morphology. We document distinct differences between systems, located ~40 km apart, attributed underlying structure and lithology, shelf gradient, drainage basin characteristics. A cross-shelf valley exi...

The scallop Zygochlamys delicatula is an indicator species for a carbonate shellground facies which occurs on the sediment-starved outer shelf and upper slope around southern New Zealand. The modern distribution of Z. delicatula is restricted to areas where sea summer surface temperatures are less than ca. 15oC. Its occurrence in Late Pliocene and Pleistocene strata in North Island has, therefo...

This study investigates the postglacial sea-level history of eastern Cumberland Peninsula, a region Baffin Island, Nunavut, where submerged terraces were documented in 1970s. The elevation gradient emerged marine-limit deltas and fiord-head moraines led Arthur Dyke to propose conceptual model for continuous submergence peninsula. Multibeam mapping over past decade has revealed eight unequivocal...
