Bathymetric change of Central San Francisco Bay, California: 1971 to 2020

Metadata Updated: July 6, 2024

This 25-m-resolution surface presents bathymetric change of Central San Francisco Bay, California (hereafter referred to as Central Bay). This surface compares a 1-m-resolution digital elevation model (DEM) of the central portion of San Francisco Bay (Fregoso and others, 2021), comprised of bathymetry data in the Central Bay region from the time period referred to as the 2010s because the majority of the surveys were in that decade, to a 25-m-resolution DEM of Central Bay comprised of historic surveys from 1971 to 1984 (referred to as the 1980s because the majority of the surveys were in that decade). The creation of this change surface involved the resampling of the 1-m-resolution 2010s DEM to match the 25-m-resolution 1980s Central Bay DEM. Adjusting the 1990 surface to account for the modern tidal cycle while also applying a bias correction in attempts to account for interpolation uncertainties.
