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.

Meteorological, seawater temperature, and current velocity data, from Ofu, American Samoa, 2020 Meteorological, seawater temperature, and current velocity data, from Ofu, American Samoa, 2020
Time series data of meteorological and oceanographic data (temperature & single-point currents) from the southern reef of Ofu, American Samoa, in support of a study on submarine groundwater discharge (SGD) dynamics on this reef within the National Park of American Samoa’s (NPSA) Ofu Unit. In January 2020, USGS scientists, in collaboration with NPSA, initiated an extensive field study on...
Data supporting investigations of lodgepole pine tree mortality in the Upper Geyser Basin, Yellowstone National Park Data supporting investigations of lodgepole pine tree mortality in the Upper Geyser Basin, Yellowstone National Park
More than half of Earth’s natural geysers are concentrated in Yellowstone National Park, mostly in the Upper Geyser Basin. Data were collected to support a study investigating the causal mechanisms linking geyser eruptions to lodgepole pine tree mortality and growth declines near Grand and Riverside Geysers in the Upper Geyser Basin. At these locations, growth-impacted and dead lodgepole...
Luminescence Data for Holocene and Late Pleistocene surface faulting, Monument Hill fault, Red Rock Valley, southwest Montana Luminescence Data for Holocene and Late Pleistocene surface faulting, Monument Hill fault, Red Rock Valley, southwest Montana
This data release contains luminescence data associated with 10 samples collected to accompany detailed geomorphic mapping and interpretations of two paleoseismic trenches along the Monument Hill fault, a northwest-striking fault bounding the eastern Red Rock Valley in southwestern Montana. These optically stimulated luminescence ages, between >80 and 8 ka, provide new information to...
Using wildfire tracer molecules to investigate the role of eolian dust and aerosols on pedogenesis and watershed chemistry in the Colorado Front Range Using wildfire tracer molecules to investigate the role of eolian dust and aerosols on pedogenesis and watershed chemistry in the Colorado Front Range
This data release compiles concentrations of biomass-burning biomarkers, including the monosaccharide anhydride levoglucosan and its stereoisomers mannosan and galactosan, measured in water samples collected during the summer of 2018 in the Green Lakes Valley (GLV) watershed of the Colorado Front Range (Table_1_Site_Locations.csv and Table_2_Constituents_Analyzed.csv). Sampling sites are...
Presumptive sources and relative heat index of 6PPD-quinone at the NHDPlus HR scale in the Delaware River Basin Presumptive sources and relative heat index of 6PPD-quinone at the NHDPlus HR scale in the Delaware River Basin
Geospatial datasets of sources and landscape characteristics expected to contribute 6PPD-quinone, a compound intended to increase the life span of tires, to surface waters were acquired and integrated into a relative heat index framework across the Delaware River Basin. 6PPD-quinone is known to be the cause of coho salmon (Oncorhynchus kisutch) kills following storm events, and recent...
Presumptive sources and relative heat index of 6PPD-quinone at the NHDPlus HR scale in the Chesapeake Bay Watershed Presumptive sources and relative heat index of 6PPD-quinone at the NHDPlus HR scale in the Chesapeake Bay Watershed

Catch of larval Grass Carp in light traps and intensity of light from light sticks Catch of larval Grass Carp in light traps and intensity of light from light sticks
Reproducing Grass Carp populations are not desired in many natural environments in the United States. Determining if reproduction is occurring, and linking reproduction to adult fish, requires capturing larval Grass Carp. A 4x4 Latin-square design was used to assess efficacy of four different light colors at capturing larval Grass Carp in quatrefoil light traps. The experiments were...
2015-2017 digital elevation models of karst areas in Puerto Rico at 3-meter resolution 2015-2017 digital elevation models of karst areas in Puerto Rico at 3-meter resolution
This raster dataset contains 3-meter digital elevation models (DEMs) of 7.5 minute quadrangles in karst areas of Puerto Rico and was created using GlobalMapper v.23 software. These DEMs were derived from 1-meter DEM tiles acquired through the USGS 3D Elevation Program (3DEP). The data are projected in North America Datum (NAD) 1983 (2011) UTM Zone 19N.
