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.

Drought-related responses of stream flow, climate, and vegetation productivity from the Donner und Blitzen watershed, Great Basin Desert, USA (1988-2020) Drought-related responses of stream flow, climate, and vegetation productivity from the Donner und Blitzen watershed, Great Basin Desert, USA (1988-2020)
Indicators of climatic, hydrologic, and ecological drought responses in water-related terrestrial and aquatic conditions within a single catchment in the northwestern Great Basin Desert and its associated stream network were developed from stream flow, climate and remote sensing sources for the time period of 1988 to 2020.
Hydrogeologic Framework and Chloride Data for Kings, Queens, and Nassau Counties, Long Island, New York Hydrogeologic Framework and Chloride Data for Kings, Queens, and Nassau Counties, Long Island, New York
This data release contains two child item datasets including a compilation of available chloride concentration data in groundwater and related isochlors as well as geospatial data defining the hydrogeologic framework for Kings, Queens, and Nassau Counties in Long Island, New York. These data are accessible as an online webmap: https://ny.water.usgs.gov/maps/lisustainabilityphase1viewer/
Simulations of the Long Island Aquifer System Response to Potential Changes in Future Hydrologic Conditions, Long Island, New York (ver. 1.1, June 2025) Simulations of the Long Island Aquifer System Response to Potential Changes in Future Hydrologic Conditions, Long Island, New York (ver. 1.1, June 2025)
This data release contains simulation results from fifteen transient, regional-scale numerical models of the Long Island aquifer system that predict aquifer conditions resulting from possible future changes in pumping and recharge stresses and sea level altitude. These models are based on the MODFLOW 6 numerical model that is documented in Walter and others (2024), which simulates...
Emperor Goose (Anser canagicus) Nest Visit, Fate, and Dispersal Distances from the Yukon-Kuskokwim Delta, Alaska, 2000-2017 Emperor Goose (Anser canagicus) Nest Visit, Fate, and Dispersal Distances from the Yukon-Kuskokwim Delta, Alaska, 2000-2017
These data are in two tables: 1) table relating to emperor goose nest visit, nest fate, and nest dispersal distances on the Yukon-Kuskokwim Delta in Alaska, 2000-2017; 2) table with means and standard deviations for posterior distributions of predicted nest-age and year specific daily nest survival probabilities for emperor geese derived from estimates reported by Thompson et al. (2023)...
Annual burn severity mosaics for the southeastern United States (2000-2022) Annual burn severity mosaics for the southeastern United States (2000-2022)
The southeastern United States experiences frequent wild and prescribed fire activity. Mapped burn severity products in the southeastern U.S. face challenges accurately characterizing fire effects due to rapid post-fire recovery limiting observation windows, limited availability of cloud-free imagery, spectral confusion within wetland areas, and operational constraints. As mapped burn...
Water Quality and Toxic Algal Presence in Burrow Pits in Eastern Lake Pontchartrain: 2021-2023 Water Quality and Toxic Algal Presence in Burrow Pits in Eastern Lake Pontchartrain: 2021-2023
This dataset consists of sensor profile and water sample results from monitoring campaign to investigate the effects of two dredged pits in eastern Lake Pontchartrain on dissolved oxygen conditions within the water column in and surrounding the pits over a three-year period. The borrow pits were excavated to provide soil material to nourish three nearby protected marsh sites: Bayou...
