The Tomales Bay Watershed Council has voiced a need to begin looking at the environmental impacts of human input to the watersheds and feels it important to establish an ecological database that can be used to make comparisons in the future. Surveying would create a framework and this database.

Tomales Bay marks the trace of the San Andreas Fault and is the culmination point of tributaries from the Inverness Ridge to the west and the watershed to the east. Geologic and anthropogenic changes are occuring in the Bays and the impact on habitats is unknown. In response to a request from the National Park Service, and the Tomales Bay Watershed Council [http://www.tomalesbaywatershed.org/] to determine the overall morphology of the floor of Tomales Bay, the Coastal and Marine Geology Team proposes to map the bathymetry and produce a detailed geologic and habitat map of Tomales and Bodega Bays. This task is necessary to establish a baseline of the bay floor morphology to compare future geologic and anthropogenic changes that might occur due to changes in land use or development in the surrounding watershed. This task will also be of importance in determining the possible pathways of pollutants entering the bays from the surrounding watersheds.
