Summary

This data release provides a series of five bathymetric change grids generated from historical bathymetric surveys collected in south San Francisco Bay, CA from the 1858 to 2005. The National Ocean Service (NOS) and its predecessor, the United States Coast and Geodetic Survey, collected hydrographic surveys in 1858, 1898, 1931, 1956, and 1983 plus Sea Surveyor, Inc. collected a survey in 2005. Surface modeling software was used to generate bathymetric DEMs of each of these surveys. The bathymetric DEMs were then adjusted to account for gridding interpolation bias, changes in sea level through time, and ground subsidence that occurred in the Santa Clara Valley and lower South Bay from the 1930s to 1960s due to groundwater extraction.

Purpose

Analysis of historical bathymetric surveys enables us to reconstruct the surface of the bay floor through time and quantify spatial and temporal changes in deposition, erosion, and bathymetry over decadal timescales. These data provide insight on changes to San Francisco Bay in response to natural processes as well as anthropogenic activities and can inform numerous studies and applications such as sediment management practices, restoration projects, regional adaptation plans, contaminant transport research, and sea-level rise studies. These data are intended for science researchers, students, policy makers, and the general public. These data can be used with geographic information systems (GIS) or other software to identify changes in the depth of the bay floor through time. These data are not intended to be used for navigational purposes.
