Science Datasets

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.

Isotope concentrations in different mayfly life stages

This release is for data on Zinc concentrations and isotopic signatures of an aquatic insect (mayfly, Baetis tricaudatus). Mayflies were exposed to an aqueous zinc concentration gradient in a laboratory experiment. Zinc concentrations were measured in water, algae (mayfly food), and different mayfly lifestages. Natural abundances of carbon and nitrogen isotopes were also measured

Estimated low-flow statistics at un-gaged stream locations in New Jersey, water year 2016

Estimates of various low-flow statistics were computed at 61 ungaged stream locations throughout New Jersey during the 2016 water year using methods in the report, Streamflow Characteristics and Trends in New Jersey, Water Years 1897-2003 (U.S. Geological Survey Scientific Investigations Report 2005-5105). The estimates are computed as needed for use in water resources permitting, asses

CoSMoS (Coastal Storm Modeling System) Southern California v3.0 Phase 2 ocean-currents projections: 1-year storm in Ventura County

Model-derived ocean current velocities (in meters per second) for the given storm condition and sea-level rise (SLR) scenario.
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 sea-level rise (SLR) scenarios. CoSMoS

Turbidity data from the Carmel River, central California, 2014 to 2017

This data provides river turbidity measurements collected on the Carmel River, CA. Turbidity was measured to study any changes in the Carmel River’s sediment loads following the removal of the San Clemente Dam. The USGS-run DTS-12 turbidity sensor was deployed above the Sleepy Hollow Weir on the Carmel River, CA (instrument was located at 36.445250 degrees North, 121.710494 degree

Barometric Pressure Dataset at Santa Cruz River at Tubac, Arizona, Geographic NAD83 (Water Years 2015–2017)

This dataset contains barometric pressure collected at the Santa Cruz River at Tubac, Arizona (SC14, 09481740). The data were recorded using a Solinst 3001 Barologger for the period of February 12, 2015 to December 31, 2016. The data were logged continuously at a 15-minute interval and manually downloaded. Non-vented pressure transducers do not correct for atmospheric pressure, ther

Hydrologic and Landscape Database for the Cahaba River National Wildlife Refuge and Contributing Watersheds, Alabama

This hydrologic and landscape database was developed by the U.S. Geological Survey, in cooperation with the U.S. Fish and Wildlife Service for the Cahaba River National Wildlife Refuge and contributing watersheds in Alabama. The database was developed as an assessment and evaluation tool to use in examining refuge-specific hydrologic patterns and trends as related to water availability and...

Argon geochronology data from the Hall Creek caldera, Toiyabe Range, Nevada

The magmatic, tectonic, and topographic evolution of what is now the northern Great Basin remains controversial, notably the temporal and spatial relation between magmatism and extensional faulting. This controversy is exemplified in the northern Toiyabe Range of central Nevada, where previous geologic mapping suggested the presence of a caldera that sourced the late Eocene (34.0 mega-a

Sea-floor environments in the Hudson Canyon region (polyline shapefile, geographic, WGS 84)

The Hudson Canyon begins on the outer continental shelf off the east coast of the United States at about 100-meters (m) water depth and extends offshore southeastward across the continental slope and rise. A multibeam survey was carried out in 2002 to map the bathymetry and backscatter intensity of the sea floor of the Hudson Canyon and adjacent slope and rise. The survey covered an area appr...
