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.

Hydrographic and sediment field data collected in the vicinity of Wainwright, Alaska, in 2009 Hydrographic and sediment field data collected in the vicinity of Wainwright, Alaska, in 2009
This dataset consists of hydrographic, geomorphic, and sediment field measurements obtained during the ice-free summer of 2009 in the vicinity of Wainwright, Alaska. Time-series data were collected with a bottom-mounted instrument package and consist of wave statistics, vertical water flow velocity profiles, water temperatures, conductivity, and salinity concentrations. Data collected at...
Predictions of lake water temperatures for eight reservoirs in Missouri US, 1980-2021 Predictions of lake water temperatures for eight reservoirs in Missouri US, 1980-2021
Lake temperature is an important environmental metric for understanding habitat suitability for many freshwater species and is especially useful when temperatures are predicted throughout the water column (known as temperature profiles). This dataset provides estimates of water temperature at half meter depths for eight reservoirs in Missouri, USA using version 3 of the General Lake...
Compilation of thermal maturity and source rock geochemistry data from the Permian Basin Province, west Texas and southeast New Mexico (ver. 2.0, February 2026) Compilation of thermal maturity and source rock geochemistry data from the Permian Basin Province, west Texas and southeast New Mexico (ver. 2.0, February 2026)
This data release is a compilation of published and unpublished thermal maturity and source rock geochemical data (Rock-Eval, pyrolysis) from subsurface wells in the Permian Basin, west Texas and southeast New Mexico. These data include 67 newly collected samples and analyses from Delaware Basin wells (identified as Cicero_2022), as well as 1028 previously unpublished USGS analyses from...
Microbial nitrification gene data (ammonia monoxygenase, or amoA) from alpine glacial and snow-fed headwater ecosystems Microbial nitrification gene data (ammonia monoxygenase, or amoA) from alpine glacial and snow-fed headwater ecosystems
These data describe how microorganisms facilitate the cycling of reactive nitrogen in alpine ecosystems. Samples of water and sediment were collected from a longitudinal study of Loch Vale watershed in Rocky Mountain National Park in 2011 and 2012. Data presented include concentrations of NO3+ and NH4+ of surface waters and the relative abundance of nitrifying bacteria in both the water...
Soil and surface water nitrogen and caffeine data from 2019, and 2019-2020 trail counts of hikers in Loch Vale Watershed, Rocky Mountain National Park Soil and surface water nitrogen and caffeine data from 2019, and 2019-2020 trail counts of hikers in Loch Vale Watershed, Rocky Mountain National Park
Daily visitor use in Rocky Mountain National Park has increased substantially since 2014, raising questions about the impact of human waste on water quality in popular areas without latrines. Human urine contributes nitrogen, and the ecological and biogeochemical effects of nitrogen from atmospheric deposition have long been the topic of study in Loch Vale watershed, Rocky Mountain...
Region Layers for USGS South Carolina Bohman Method Hydrograph in StreamStats Region Layers for USGS South Carolina Bohman Method Hydrograph in StreamStats
In cooperation with the South Carolina Department of Transportation (SCDOT), the U.S. Geological Survey prepared geospatial layers illustrating the boundaries of the regions used in the South Carolina (SC) Stream Hydrograph Methods presented in Bohman (1990,1992). The region limits were described in written text and depicted in figures in Bohman (1990, 1992), but have not been provided...
