Bathymetric change analysis in San Francisco Bay, California, from 1971 to 2020 Bathymetric change analysis in San Francisco Bay, California, from 1971 to 2020
This data release provides bathymetric change grids of four geographic areas of San Francisco Bay, California, comparing digital elevation models (DEMs) created from bathymetric data collected in the 1970s and 1980s with DEMs created from bathymetric data collected in the 2010s and 2020. These types of change analyses can provide information on the quantities and patterns of erosion and...
Future coastal hazards along the U.S. Atlantic coast Future coastal hazards along the U.S. Atlantic coast
This product consists of several datasets that map future coastal flooding and erosion hazards due to sea level rise (SLR) and storms for three States (Florida, Georgia, and Virginia) along the Atlantic coast of the United States. The SLR scenarios encompass a plausible range of projections by 2100 based on the best available science and with enough resolution to support a suite of...
Future coastal hazards along the U.S. North and South Carolina coasts Future coastal hazards along the U.S. North and South Carolina coasts
This product consists of several datasets that map future coastal flooding and erosion hazards due to sea level rise (SLR) and storms along the North and South Carolina coast. The SLR scenarios encompass a plausible range of projections by 2100 based on the best available, science and with enough resolution to support a suite of different planning horizons. The storm scenarios are...
Coastal Storm Modeling System (CoSMoS) for Northern California 3.2 (ver. 1h, December 2025) Coastal Storm Modeling System (CoSMoS) for Northern California 3.2 (ver. 1h, December 2025)
The Coastal Storm Modeling System (CoSMoS) makes detailed predictions (meter-scale) over large geographic scales (100s of kilometers) of storm-induced coastal flooding and erosion for both current and future scenarios. CoSMoS 3.2 for Northern California shows projections for future scenarios (sea-level change and storms) to provide emergency responders and coastal planners with critical...
Bathymetric surveys collected near Dumbarton Bridge in south San Francisco Bay, California, 2008 to 2019 Bathymetric surveys collected near Dumbarton Bridge in south San Francisco Bay, California, 2008 to 2019
In 2008, the U.S. Geological Survey began mapping the main channel and shallow intertidal mudflats between the Dumbarton Bridge and a railroad bridge located 1 km to the south in south San Francisco Bay. This information was collected to document bathymetric change before and after restoration to inform the South Bay Salt Pond Restoration Project (https://www.southbayrestoration.org)...
High-resolution (1 m) digital elevation model (DEM) of San Francisco Bay, California, created using bathymetry data collected between 1999 and 2020 (ver. 2.0, July 2021) High-resolution (1 m) digital elevation model (DEM) of San Francisco Bay, California, created using bathymetry data collected between 1999 and 2020 (ver. 2.0, July 2021)
A 1-m resolution bathymetric digital elevation model (DEM) of all off San Francisco Bay was constructed from bathymetric surveys collected from 1999 to 2016. The DEM has been divided into northern and southern sections due to file size, and is available in both MLLW and NAVD88 versions. Background: In 2014 and 2015 the California Ocean Protection Council (OPC) contracted the collection...

Sediment deposition, erosion, and bathymetric change in San Francisco Bay, California, 1971–1990 and 1999–2020 Sediment deposition, erosion, and bathymetric change in San Francisco Bay, California, 1971–1990 and 1999–2020
Bathymetric change analyses document historical patterns of sediment deposition and erosion, providing valuable insight into the sediment dynamics of coastal systems, including pathways of sediment and sediment-bound contaminants. In 2014 and 2015, the Office for Coastal Management, in partnership with the National Oceanic and Atmospheric Administration (NOAA) Office of Coastal...

South San Francisco Bay Salt Pond Restoration Project—A synthesis of Phase-1 mercury studies South San Francisco Bay Salt Pond Restoration Project—A synthesis of Phase-1 mercury studies
The South Bay Salt Pond Restoration Project (SBSPRP) encompasses over 6,000 hectares of former salt production ponds along the south edge of the San Francisco Bay and represents the largest wetland restoration effort on the west coast of North America. A series of studies associated with Phase 1 (2010–2018) restoration activities that are focused on a historically mercury contaminated...

Dynamic flood modeling essential to assess the coastal impacts of climate change Dynamic flood modeling essential to assess the coastal impacts of climate change
Coastal inundation due to sea level rise (SLR) is projected to displace hundreds of millions of people worldwide over the next century, creating significant economic, humanitarian, and national-security challenges. However, the majority of previous efforts to characterize potential coastal impacts of climate change have focused primarily on long-term SLR with a static tide level, and...

Slough evolution and legacy mercury remobilization induced by wetland restoration in South San Francisco Bay Slough evolution and legacy mercury remobilization induced by wetland restoration in South San Francisco Bay
Coastal wetlands have a long history of degradation and destruction due to human development. Now recognized as one of the most productive ecosystems in the world, substantial efforts are being made to restore this critical habitat. While wetland restoration efforts are generally viewed as beneficial in terms of providing wildlife habitat and flood control, they are often accompanied by...

Modeling morphodynamic development in the Alviso Slough system, South San Francisco Bay, California Modeling morphodynamic development in the Alviso Slough system, South San Francisco Bay, California
Alviso Slough area, South San Francisco Bay, California, is the site of an ongoing effort to restore former salt production ponds to intertidal habitat. As restoration proceeds and the levees surrounding the former salt production ponds are breached, the increase in tidal prism and associated sediment scour in the sloughs will remobilize legacy mercury deposits. A numerical model that is...

Assessing and communicating the impacts of climate change on the Southern California coast Assessing and communicating the impacts of climate change on the Southern California coast
Over the course of this and the next century, the combination of rising sea levels, severe storms, and coastal erosion will threaten the sustainability of coastal communities, development, and ecosystems as we currently know them. To clearly identify coastal vulnerabilities and develop appropriate adaptation strategies for projected increased levels of coastal flooding and erosion...
