Investigation of Sedimentary Processes on Millennial Timescales in an Accretionary Continental Margin Setting

Abstract

The focus of my work in the first two phases of STRATAFORM has been oriented toward identifying the sedimentary processes that act together to produce the characteristic deposits of the uppermost seabed (< 50 cm depth) over short timescales (100-y and less). Over centuries to millennia, sediment discharge, climate, and sea-level all change significantly, affecting the preserved record of sedimentary processes in the margin and the dominant processes responsible for acoustic stratigraphy observed in seismic profiles. The long-term goal of this project is to determine the millennial-scale sedimentary processes that are responsible for the development of acoustic stratigraphy and the characteristic signatures of these processes. A good understanding of the significance of reflectors imaged in the seabed is of critical importance to achieving the goals of the STRATAFORM program.
