In 2016, the National Geological and Geophysical Data Preservation Program (NGGDPP) sponsored data and collection preservation projects conducted by state geological surveys. Descriptions of state preservation projects, including access to preserved collections via state geological survey websites and the NGGDPP National Digital Catalog, are provided.

In California, land subsidence—mostly from groundwater pumping—was first documented by the USGS in the early 20th century. Completion of State and Federal water projects that bring water from California's wet north to its dry south allowed some groundwater aquifers to recover, and subsidence decreased in these areas. Subsidence continues today, sometimes at high rates of more than 1 foot/year.

The Vegetation Dynamics/Drought viewer provides a dynamic online map interface that can be used to view USGS and other data.

The United States Geological Survey (USGS) Land Cover Trends field photography collection is 33,000 ground-referenced photos at a national-scale. The photos initially served as a research tool to aid in Landsat-derived land-use/land-cover (LULC) change analyses and assessments between 1999 and 2009.

The degree to which eelgrass on river deltas provides critical habitat for estuarine fishes, especially out‐migrating juvenile salmon, is an important scientific and management issue that bears on efforts to conserve and restore both eelgrass and fish.

This interactive webmap plots water-quality data from domestic and public-supply wells sampled by the USGS for the California Groundwater Ambient Monitoring and Assessment (GAMA) Program Priority Basin Project (GAMA-PBP), and allows users to download datasets. The GAMA-PBP is a cooperative program between the California State Water Resources Control Board and the U.S. Geological Survey. 

Interactive map of the Mojave and Morongo groundwater basins.  Data layers include sites and data for groundwater levels, water quality, and land subsidence.  Groundwater data spans 1994 to the present.

This is a Story Map that provides a broad overview of the research performed at USGS that is relevant to the field of wildland fire science.

The USGS monitors current streamflow and water-quality conditions at various sites in the Animas and San Juan River Basins in Colorado, New Mexico, and Utah, including areas below the Gold King Mine release area. These streamgages provide continuous data on streamflow and select water-quality constituents including specific conductance, water temperature, pH, and turbidity.

This web mapping application allows users to make comparisons between national scale environmental datasets and Bacillus species and Bacillus anthracis detection results. The datasets include soil physical, chemical, and mineralogical data, current and historical climate data, landcover, and biological surveys.

U.S. Geological Survey (USGS) scientists are leading a diverse range of studies to address CyanoHAB issues in water bodies throughout the United States, using a combination of traditional methods and emerging technologies, and in collaboration with numerous partners.
