Integrated Investigation of Inner-Shelf Strata on the Eel Margin: the Coarse-Grained Portion of a Transgressive Shelf Sequence.

摘要

The ultimate goal of this research is to understand the mechanisms by which continental-margin sediment is deposited, modified and preserved, so strata recorded over various time scales (events to millennia) can be interpreted better. The fieldwork is undertaken on the Eel margin within the larger context of the STRATAFORM program, and has objectives that complement those of other groups. In particular, this project is designed to document event beds (i.e., flood, storm) immediately after they form, to observe their subsequent modification and preservation, and to interpret geologic history from old beds buried at various depths within the seabed (10s of centimeters to meters). These objectives were focused during the past year on the inner shelf and on Eel canyon. The work was expanded to investigate similarly a flood deposit associated with the Po River in the northern Adriatic Sea. In addition, the overall STRATAFORM program is coordinated through efforts to: orchestrate program planning, organize field operations, and disseminate scientific results.
