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.

MODFLOW-NWT model used to simulate water-table and freshwater/saltwater interface response to climate-change-driven sea-level rise and changes in recharge at Fire Island National Seashore, New York MODFLOW-NWT model used to simulate water-table and freshwater/saltwater interface response to climate-change-driven sea-level rise and changes in recharge at Fire Island National Seashore, New York
The U.S. Geological Survey, in cooperation with the National Park Service (NPS), developed a three-dimensional groundwater-flow model to simulate climate change related changes in depth to the water table and depth to freshwater/saltwater interfaces for the Fire Island National Seashore, New York. An existing SEAWAT three-dimensional variable-density groundwater flow and transport model...
Horizontal-to-Vertical Spectral Ratio and Depth-to-Bedrock Data for Saline-Groundwater Investigation in the Genesee Valley, New York, October-November 2016 and 2017 Horizontal-to-Vertical Spectral Ratio and Depth-to-Bedrock Data for Saline-Groundwater Investigation in the Genesee Valley, New York, October-November 2016 and 2017
In October and November of 2016 and 2017, the U.S. Geological Survey collected horizontal-to-vertical spectral ratio (HVSR) data at 104 sites in the Genesee Valley, Livingston County, New York as part of a saline-groundwater investigation in cooperation with the New York State Department of Environmental Resources. The HVSR technique, commonly referred to as the passive-seismic method...
Protein and Fat Consumption of Zoo Polar Bears in 14-day Ad Libitum Trials, 2019-2020 Protein and Fat Consumption of Zoo Polar Bears in 14-day Ad Libitum Trials, 2019-2020
This is a single table containing measures of the amount of fat and meat consumed by 4 adult female and 5 adult male polar bears in U.S. zoos when provided both food sources ad libitum for 12-14 days. Trial length was intended to be 14 days, but trial dietary items ran out for two bears prior to the end of the trial (i.e., at 12 and 13 days instead of 14 days). The data set includes the...
Long-term CO2 emissions measurements, Horseshoe Lake tree kill area, Mammoth Mountain, CA Long-term CO2 emissions measurements, Horseshoe Lake tree kill area, Mammoth Mountain, CA
We installed an eddy covariance station on July 22, 2014 at the Horseshoe Lake tree kill area on Mammoth Mountain, CA to monitor variations in magmatic CO2 emissions. Since then, this station has measured CO2, H2O and sensible and latent heat fluxes, air temperature and pressure, and wind speed and direction on a half-hourly basis. We also measured soil CO2 fluxes across the area (0.32...
Unoccupied Aircraft Systems (UAS) video of the 2018 summit eruption of K?lauea Volcano, Hawaii Unoccupied Aircraft Systems (UAS) video of the 2018 summit eruption of K?lauea Volcano, Hawaii
This dataset contains Unoccupied Aircraft Systems (UAS) footage from the 2018 summit collapse of Kilauea Volcano, Island of Hawai'i. The intrusion of magma into Kilauea's lower East Rift Zone triggered draining of the summit lava lake and magma withdrawal from the shallow reservoir. This resulted in 62 subsequent collapse events at the summit between May and early-August 2018. Each...
Survey Data Collection for the Bureau of Reclamation at Glen Canyon Dam near Page, Arizona, November 2020 Survey Data Collection for the Bureau of Reclamation at Glen Canyon Dam near Page, Arizona, November 2020
This dataset describes survey data collected for the Bureau of Reclamation (Reclamation), the agency in charge of regulating Colorado River water control operations impounding the Lake Powell reservoir. Additional intent of the collected data was to assure consistencies among gaging elevations at Glen Canyon Dam near Page, Arizona as well as verification and alignment of a recently...
