Data and Tools

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.

LEAN-Corrected DEM for Suisun Marsh

Lidar-derived digital elevation models often contain a vertical bias due to vegetation. In areas with tidal influence the amount of bias can be ecologically significant, for example, by decreasing the expected inundation frequency. We generated a corrected digital elevation mode (DEM) for Suisun marsh using a modification of the Lidar Elevation Adjustment with NDVI (LEAN) technique (Buffington...

Post-expedition report for USGS T-3 ice island heat flow measurements in the High Arctic Ocean, 1963-1973

 In February 1963, the U.S. Geological Survey (USGS) began a study of heat flow in the Arctic Ocean Basin and acquired data at 356 sites in Canada Basin and Nautilus Basin and on Alpha-Mendeleev Ridge by the end of the project in 1973. The USGS heat flow and associated piston coring operations were conducted from a scientific station on the freely drifting T-3 Ice island.

Tellurium Deposits in the United States

This data release provides the description of U.S. sites that include mineral regions, mines and mineral occurrences (deposits) that have a contained resource and (or) production of tellurium metal greater than 1 metric ton. For this data release, only one deposit in the U.S. with historic production records was found: Butte, Montana. We did not locate any deposits in the U.S. that list Te...

Glacier-Wide Mass Balance and Compiled Data Inputs: USGS Benchmark Glaciers

Since the late 1950s, the USGS has maintained a long-term glacier mass-balance program at three North American glaciers. Measurements began on South Cascade Glacier, WA in 1958, expanding to Gulkana and Wolverine glaciers, AK in 1966, and later Sperry Glacier, MT in 2005. Additional measurements have been made on Lemon Creek Glacier, AK to compliment data collected by the Juneau Icefield...
