2021. San Francisco Bay North Bay Margins Sediment Report. Marine Pollution Studies Lab: Moss Landing, California.

This report contains information on the late summer/early fall field sampling efforts conducted
by the Marine Pollution Studies Lab at Moss Landing Marine Labs (MPSL-MLML) in support of
the San Francisco Bay Regional Monitoring Program (RMP) North Bay (San Pablo and Suisun
Bays) Margins study. The North Bay Margins is the third and final round of a larger San
Francisco Bay study collecting sediment and water in shallow margin areas of the bay. The first
round was conducted in Central Bay in 2015 and second round in South Bay in 2017. The work
was contracted through the San Francisco Estuary Institute (SFEI) to the San Jose State
University Research Foundation (SJSURF).
This report includes sample collections over a three week period (August 31st through September
16th) in 2020 encompassing two trips. A total of 40 sediment sites were sampled (Appendix A).
Duplicate sediment samples were collected at two sites (SPB039 and SUB25). Detailed sample
counts and protocols can be found in the 2020 RMP Bay Margins Sediment Cruise Plan prepared
by SFEI.
