Physical and Biological Effects on Tide Flat Sediment Stability and Strength - Phase 2

Abstract

This research is part of the Tidal Flats Department Research Initiative (DRI) that (amongst other goals) is focused on understanding the controls of sediment strength over multiple time and space scales on the mudflats of Willapa Bay, Washington. My role in the DRI is to: (1) obtain high-resolution profiles of sediment bulk density to compare against erodibility measured by other investigators, and (2) collect time series data on near-surface porosity, as well as seagrass abundance, surficial particulate organic carbon content, and chlorophyll-a concentration. The latter are both proxies of exopolymeric substances (EPS), which are known to affect sediment erodibility.
