San Francisco Bay Bathymetry
Lead
U.S. Geological Survey [USGS]
Description
USGS has conducted bathymetric analyses in San Francisco Bay, Suisun Bay, and the Delta intermittently since 1867 based on bathymetry data primarily collected by NOAA"s National Ocean Service (NOS) (formerly the United States Coast and Geodetic Survey (USCGS)). Since the days of hydraulic gold mining, sedimentation in San Francisco Bay has changed drastically. From the 1850's until at least the late 1800's, debris from hydraulic mining in the Sierra Nevada filled the Bay. As hydraulic mining practices ceased, the amount of sediment deposited decreased. In the latter half of the 20th century an increase in the implementation of flood control and water distribution projects in the Central Valley caused the Bay to be erosional due to the reduction of the frequency and duration of peak flow conditions, which in turn decreased sediment supply to the Bay. They have used this information to locate deposits of sediment-associated contaminants, restore wetland areas, and to provide the observable linkage between anthropogenic modifications of the landscape—such as evolving land use practices, flood control, and water diversions—and natural forces of climate-driven river flow, sea level change, tides, and wind. In 1999, USGS assessed how sedimentation in the Suisun Bay has changed between 1867 and 1990 (see info sources). They have also worked collaboratively with DWR, using their more recent bathymetry data to produce a high-resolution DEM of the Delta region (see info sources). It is not clear whether USGS will continue their bathymetry surveys. The latest survey is from 2005, and took place in the South of San Francisco Bay (outside the Delta study area).

Multibeam Delta Bathymetry Surveys
Lead
California Department of Water Resource [DWR]
Description
The California Department of Water Resources (CA-DWR), North Central Region Office (NCRO), Bathymetry and Technical Support Section has conducted bathymetry surveys in the Delta since 2011 (according to the Bathymetry Catalog). Data have been used to support planning for the installation of behavioural fish barriers, to assess the river’s channel capacity and ability to convey flows, to assess water quality dynamics, to better understand the area’s risk of flooding and to improve the quality of flood hazard data and maps available to local communities (under the DWR’s FloodSAFE California Initiative), to improve knowledge of sediment presence and movement, to provide high-resolution bathymetry data for hydraulic models, to assess the placement of a drought barrier, to determine how the channel bottom is evolving due to the installation of an emergency drought barrier, and to determine the effects of fish passage projects.

Plate Boundary Observatory [PBO]
Lead
UNAVCO
Description
The Plate Boundary Observatory (PBO) is the geodetic component of the EarthScope project, designed to study the 3D strain field across the active boundary zone between the Pacific and North American tectonic plates in the western United States. PBO is a network of more than 1,200 continuous GPS instruments, borehole strainmeters and seismometers, and tiltmeters installed primarily throughout the Western United States. The objective of PBO is to explore land motions related to movement of the Pacific, Juan de Fuca, and North American tectonic plates;such motions inform us about earthquakes, volcanoes, tsunamis, and other hazards related to plate tectonics. Data from PBO's integrated network of GPS stations, strainmeters and seismometers, coupled with aerial and satellite imagery, are providing important temporal constraints on plate boundary deformation and are improving our knowledge of the fundamental physics that govern deformation, faulting, and fluid transport in earth’s lithosphere. PBO is also used to remotely measure changes in water content of the troposphere, soil moisture content, snow depth, and ground motions related to changes in aquifers, droughts, and lake levels.

Berkeley Seismology Lab Geophysical Networks
Lead
U.S. Geological Survey [USGS]
Description
Together with the USGS Menlo Park, the Berkeley Seismological Laboratory reports earthquake information within a few minutes of occurrence. The BSL operates several different networks and has expanded into a broader range of geophysical monitoring: BARD, BDSN, BBN, and HRSN. BARD is a network of 33 continuously operating Global Positioning System receivers in Northern California. The primary goal of the network is to monitor crustal deformation across the Pacific-North America plate boundary and in the San Francisco Bay Area for earthquake hazard reduction studies and rapid earthquake emergency response assessment. The Berkeley Digital Seismic Network (BDSN) is a regional network of very broadband and strong motion seismic stations spanning Northern California and linked to UC Berkeley through continuous telemetry. The network is designed to monitor regional seismic activity as well as to provide high quality data for research in regional and global broadband seismology. The network currently consists of 40 stations, including an ocean-bottom seismometer in Monterey Bay (MOBB). The BSL operate a number of stations in the Bay Area with seismic and other geophysical sensors in boreholes. They are tools for observing tiny earthquakes and other deformation signals that may hint of incipient seismic movements. The High-Resolution Seismic Network is an array of borehole instrumentation deployed in the Parkfield area, with the goal of monitoring microseismicity on the San Andreas fault.

California Strong Motion Instrumentation Program [CSMIP]
Lead
California Department of Conservation [DOC]
Description
The California Strong Motion Instrumentation Program (CSMIP) in the Department of Conservation's California Geological Survey was established in 1972 to obtain vital earthquake data for the engineering and scientific communities through a statewide network of strong motion instruments. The information gathered by CSMIP is processed and disseminated to seismologists, engineers, building officials, local governments and emergency response personnel throughout the state. The data is used to develop recommended changes to seismic provisions of building codes, to assist local governments in their general plan process and to aid emergency response personnel in the event of a disaster. CSMIP is funded by a portion of local government building permit fees, with additional funding from other State and Federal agencies.

Regional Geologic Mapping Program [RGMP]
Lead
California Department of Conservation [DOC]
Description
The Geologic Mapping Program was established to prepare and maintain a baseline source of the most current information on the framework geology of California. CGS geologists map and compile geologic maps of the state and its offshore continental margin at various scales. These efforts are partly supported by the U.S. Geological Survey through the National Cooperative Geologic Mapping Program The Geologic Mapping Program works in cooperation with the U.S. Geological Survey (USGS) through STATEMAP and SCAMP. Geologic mapping priorities are established under the direction of the State Geologist and the California Geologic Mapping Advisory Committee. The RGMP has also produced Statewide Geologic Maps at various scales, and Regional Geologic Maps at 1:250,000 scale. Currently the 2010 State Geologic Map of California (Geologic Data Map No. 2) at 1:750,000 scale (1 inch = approximately 12 miles) is the most detailed statewide map. A simplified geologic map at 1:2,250,000 scale is also available. The more detailed Regional Geologic Maps at 1:250,000 scale are available for the entire state a​s part of the Geologic Atlas of California series or the Regional Geologic Map series. As mentioned above, more recent maps in the Regional Geologic Map series are being prepared at 1:100,000 scale. These are available from CGS Publications and our Preliminary Geologic Maps web page​. Many CGS geologic maps can also be found through the CGS Information Warehouse.

Seismic Hazards Program
Lead
California Department of Conservation [DOC]
Description
The Seismic Hazards Program delineates areas prone to ground failure and other earthquake-related hazards including soil liquefaction (the failure of water-saturated soil), earthquake-induced landslides, surface fault rupture, and tsunami inundation. Cities and counties are required to use these maps in their land-use planning and building permit processes so that these hazards are identified and mitigated for development projects prior to the next major earthquake. Additionally, the program reviews and provides comments on geologic and seismic hazards that apply directly to the design and construction of essential and critical facilities around the state. These facilities include schools, hospitals, nuclear power plants, hazardous waste repositories, and others, typically under contract to other state agencies. The program compiles information about past earthquakes, the potential for earthquakes on major faults, and rates of deformation across California to estimate the potential for future earthquakes. The Seismic Hazards Program works closely with the U.S. Geological Survey to produce earthquake shaking maps that are used in development of building codes and in earthquake damage and loss estimates.

U.S. Geological Survey [USGS]
Description
The USGS National Strong-Motion Project (formerly titled the National Strong Motion Program) has the primary Federal responsibility for acquiring strong motion records of significant earthquakes in the United States recorded by sensors placed in the ground and in man-made structures. Currently the NSMP operates and maintains strong-motion instruments at more than 660 ground, free-field and reference sites, and more than 3200 channels of data from about 180 structural arrays. When a significant earthquake occurs, the NSMP automatically retrieves strong motion recordings from its instrumentation as well as from more than 2000 other instruments operated throughout the US by federal, state, and local agencies, private companies, and academic institutions that participate in the Advanced National Seismic System (ANSS). The NSMP rapidly processes these recordings according to COSMOS standards and archives the products at the Center for Engineering Strong Motion Data.

Assessing sea-level rise and flooding changes in the Sacramento/San Joaquin Delta using historical water-level records
Lead
California State University [CSU]
Description
The project aims to recover, digitize, and analyze more than 1300 station years of ‘lost-and-forgotten’ water level records collected from 1857 to 1982 in the Sacramento-San Joaquin Delta. These measurements, augmented by modern data, will improve our understanding of tidal, flood, and sea level trends in the system. By determining ‘hotspots’ of habitat and flood risk sensitivity, the results may be used to better focus future scientific and management priorities, to protect the environment, manage flood risk, and enhance community resilience to climate change
