AB: We collected sediment grab samples from twenty-one sites distributed within a 2-km2 area in Central San Francisco Bay, including Raccoon Strait, which is located between the Tiburon Peninsula and Angel Island. We gathered these samples in May and August of 2003, dried and disaggregated them using a Gilson Sieve Tester, and analyzed the sediments by weight percent. Our purpose in monitoring sediment distributions over time in Central San Francisco Bay is to gain understanding of the oceanographic dynamics of the bay-delta estuarine system. Our initial results indicate that grain sizes range from $>$ 2 millimeters to $<$ 125 microns with coarser samples located at the entrance to Raccoon Strait. We anticipate collecting samples from these twenty-one sites in November of 2003, and eventually relating the sediment distribution patterns to seasonal variations in transport. This study is part of a larger-scale project involving bedform migration and current transport in Central San Francisco Bay.
