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.

Potentiometric Surface Contours of the Lloyd and North Shore Aquifers, April-May 2016

This polyline shapefile consists of digital contours that represent the potentiometric-surface altitude of water in the Lloyd and contiguous North Shore aquifer beneath Nassau and Suffolk Counties, Long Island, New York. The U.S. Geological Survey constructed a potentiometric-surface altitude map using ground-water levels measured in the Lloyd and North Shore aquifers during the spring of 2016...

Blood Parasite Infection Data from Spectacled Eiders (Somateria fischeri), Alaska, 2008-2012

This dataset includes two spreadsheets associated with a study of three genera of blood parasites (Leucocytozoon, Haemoproteus, Plasmodium) in 185 Spectacled Eiders (Somateria fischeri) sampled in Alaska, 2008-2012. The first spreadsheet provides age, sex, location, and blood parasite (hematozoa) infection data for three different genera of blood parasites. Hematozoa DNA, from eider blood...

Greater White-Fronted Goose Genetic Data, Circumpolar, 1988-2009

This data set describes nuclear microsatellite genotypes derived from eight autosomal loci (BCA6, BCA9, BCA11, BCA5, CRG, OXY13, TSP1.20.09 and TSP1.20.46) and a 366 base pair portion of the mitochondrial control region. A total of 665 Greater White-fronted Geese were examined by genotyping and 518 by sequencing with samples coming from its circumpolar range representing multiple flyways (...

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 and Taku glaciers, AK to compliment data collected by the Juneau...

Water Table Data in the Upper Glacial and Magothy Aquifers, April-May 2016

Water level altitudes were measured at 275 observation wells and 1 supply well screened in the upper glacial and Magothy aquifers during April and May of 2016. This shapefile consists of the locations of those sites and includes water level altitude data stored in the attribute table. The shapefile was created and intended for use with geographic information system (GIS) software. The...

Stream and Lake Average Water-Level Altitudes, April-May 2016

Continuous records of water level altitude at 15 U.S. Geological Survey (USGS) streamgaging stations (13 streams, 1 lake and 1 pond) were retrieved from the National Water Information System (NWIS) and averaged for the months of April and May, 2016. This shapefile consists of the locations of those sites and includes water level altitude data stored in the attribute table. The shapefile was...

Water Table Contours in the Upper Glacial and Magothy Aquifers, April-May 2016

This polyline shapefile consists of digital contours that represent the water table altitude in the upper glacial and Magothy aquifer beneath Long Island, New York. The U.S. Geological Survey constructed a water table altitude map using ground-water levels measured in the upper glacial and Magothy aquifers during the spring of 2016. Contours were constructed at a scale of 1:125,000 from water-...

Approximate Regional Groundwater Divide on Long Island, New York, April-May 2016

This groundwater divide feature was approximated from and interpolated water table raster for Long Island, April-May 2016. Generally, the highest altitudes of the water table were used to draw the groundwater divide, which implies the groundwater flow direction. The feature is presented in Sheet 1 of Scientific Investigations Map 3398.

Depth to the Water Raster on Long Island, New York, 2016

The depth to water table was measured at 276 groundwater monitoring wells (observation and supply) screened in the upper glacial and Magothy aquifers during April and May of 2016. This raster data set was interpolated from the water level data collected at those sites and represents a continuous surface of the estimated depth to water for hydrologic conditions for Nassau and Suffolk Counties,...
