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.

Toxicological responses to sublethal anticoagulant rodenticide exposure in free-flying red-tailed hawks Toxicological responses to sublethal anticoagulant rodenticide exposure in free-flying red-tailed hawks
An important component of assessing the hazards of anticoagulant rodenticides to non-target wildlife are observations in exposed free-ranging individuals. The objective of this study was to determine if environmentally realistic, sublethal first-generation anticoagulant rodenticide exposures via prey, can result in direct or indirect adverse effects to free-flying raptors. We offered...
Biogeochemical and source characteristics of preferential groundwater discharge in the Farmington River watershed (Connecticut and Massachusetts, 2017 - 2021) Biogeochemical and source characteristics of preferential groundwater discharge in the Farmington River watershed (Connecticut and Massachusetts, 2017 - 2021)
We used spatial data from previously mapped preferential groundwater discharges throughout the Farmington River watershed in Connecticut and Massachusetts (https://doi.org/10.5066/P915E8JY) to guide water sample collection at known locations of groundwater discharging to surface water. In 2017 and 2019 - 2021, samples were collected during general river baseflow conditions (July –...
Seepage-run discharge measurements on Hawai'i Island and west Maui, 2021 to 2022 Seepage-run discharge measurements on Hawai'i Island and west Maui, 2021 to 2022
This data release is part of a cooperative study to assess streamflow availability under low-flow conditions for streams on the island of Hawai'i and West Maui from 2021 to 2022. This data release contains seven child items that consist of the following files: (1) a metadata xml file describing the data release files and data attributes, (2) an annotated NWIS-Mapper screen-captured image...
Riverbank vertical temperature profiler data and calculated groundwater discharge flux estimates from the Farmington River corridor, CT, USA Riverbank vertical temperature profiler data and calculated groundwater discharge flux estimates from the Farmington River corridor, CT, USA
As the climate warms and dry periods become more extreme, shallow groundwater discharge is generally becoming a less reliable source of streamflow while deep groundwater discharge remains a more resilient source. The implications of shifts in the relative balance of shallow and deep groundwater discharge sources are profound in gaining streams. These different sources exert critical...
Locations of small-scale diamond and gold dredges detected using Synthetic Aperture Radar on the Kadéï (Sangha) River, Central African Republic Locations of small-scale diamond and gold dredges detected using Synthetic Aperture Radar on the Kadéï (Sangha) River, Central African Republic
This data release catalogs the locations of small-scale diamond and gold mining dredges on the Kadéï (Sangha) River, Central African Republic from the years 2015 to 2019. The Kadéï river flows through the Nola prefecture in the CAR and is known to host placer diamond deposits. The dataset was developed through visual interpretation of 387 Synthetic Aperture Radar (SAR) scenes. The point...
Minnesota Point post-nourishment surveys of the beach topography and near-shore bathymetry of Lake Superior, Duluth, MN, September - October, 2021 (ver. 2.0, September 2024) Minnesota Point post-nourishment surveys of the beach topography and near-shore bathymetry of Lake Superior, Duluth, MN, September - October, 2021 (ver. 2.0, September 2024)
This data represents elevation of the beach topography and near-shore bathymetry of Lake Superior at two beach nourishment locations along Minnesota Point, Duluth, Minnesota. The first location is near the Superior point of entry, and was surveyed in September 2021. The second location is near the Duluth Entry and was surveyed in October 2021. LiDAR data were collected using a Velodyne...
