Data Releases
The data collected and the techniques used by USGS scientists should conform to or reference national and international standards and protocols if they exist and when they are relevant and appropriate. For datasets of a given type, and if national or international metadata standards exist, the data are indexed with metadata that facilitates access and integration.

Time Series of Structure-from-Motion Products-Orthomosaics, Digital Elevation Models and Point Clouds: Little Dauphin Island and Pelican Island, Alabama, September 2018-April 2019 Time Series of Structure-from-Motion Products-Orthomosaics, Digital Elevation Models and Point Clouds: Little Dauphin Island and Pelican Island, Alabama, September 2018-April 2019
Barrier islands are dynamic environments that are gradually shaped by currents, waves, and tides under quiescent conditions, yet can evolve in the time scale of hours to days during hurricanes and other extreme storms. Small unmanned aircraft systems (sUAS) allow the opportunity for collecting topographic data for monitoring purposes, with a temporal resolution that is well-suited for...
Reprocessed multichannel seismic-reflection (MCS) data from USGS field activity T-1-96-SC collected in San Diego Bay, California in 1996 Reprocessed multichannel seismic-reflection (MCS) data from USGS field activity T-1-96-SC collected in San Diego Bay, California in 1996
This data release presents reprocessed multichannel seismic-reflection (MCS) data that was originally collected in 1996 in partnership with the California Division of Mines and Geology and Caltrans as part of a seismic hazard assessment of the Coronado Bridge in San Diego Bay, California. The original survey collected 130 km of data with a 14-cubic inch sleeve-gun (airgun) source, a 24...
Aeromagnetic data and design files related to testing of new drone-based magnetometer configurations and magnetic compensation software; 2020 Santa Cruz, CA, and Surprise Valley, CA Aeromagnetic data and design files related to testing of new drone-based magnetometer configurations and magnetic compensation software; 2020 Santa Cruz, CA, and Surprise Valley, CA
This dataset contains magnetometry data and design files related to testing of new drone-based magnetometer configurations and magnetic compensation software. Data were collected in Santa Cruz (CA) in September 2020 to compare two magnetometer systems that are flown with Unmanned Aerial Systems (UAS). Each system was flown using different suspension designs. To compare the systems and to
Geophysical and core sample data collected offshore San Francisco, California, during field activity 2019-649-FA from 2019-10-11 to 2019-10-18 Geophysical and core sample data collected offshore San Francisco, California, during field activity 2019-649-FA from 2019-10-11 to 2019-10-18
The U.S. Geological Survey (USGS) collected geophysical and core sample data aboard the R/V Bold Horizon in 2019 on cruise 2019-649-FA offshore San Francisco, California. The data were collected to assess sand and gravel resources in Federal and State waters for potential use in future beach nourishment projects along stretches of the coast where critical erosion hotspots have been...
