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.

Point Raw Glaciological Data: Ablation Stake, Snow Pit, and Probed Snow Depth Data on USGS Benchmark Glaciers Point Raw Glaciological Data: Ablation Stake, Snow Pit, and Probed Snow Depth Data on USGS Benchmark Glaciers
This dataset contains point raw glaciological field data. Snow pit and snow core data give detailed information on snow density through the measured snow column. Snow depth measurements are collected via snow probe and in some snow pits or snow cores that extend the full depth of the snowpack to the glacier's surface. Ablation stakes allow point measurement of both snow depth and snow...
Tracking durations for marine turtles satellite tagged in Gulf of Mexico and Caribbean sites, 2008-2019 Tracking durations for marine turtles satellite tagged in Gulf of Mexico and Caribbean sites, 2008-2019
This dataset contains tracking durations for several species of sea turtles tagged with satellite tags between 2008 and 2019. It contains information on species, turtle size, capture methods, tag type, how many days each tag transmitted, whether or not the tag was still attached upon recapture, fouling 'status' of the tag, and foraging region. This dataset thus allows estimation of...
Surface-water characteristics and phytoplankton taxonomy in selected north Texas reservoirs using biological, hyperspectral, and water-quality methods, 2019-2020 Surface-water characteristics and phytoplankton taxonomy in selected north Texas reservoirs using biological, hyperspectral, and water-quality methods, 2019-2020
A study to develop an earth observation monitoring system to detect harmful algal bloom (HABs) presence within selected north Texas reservoirs using satellite imagery was conducted by the U.S. Geological Survey (USGS). This data release provides the data collected for this study including site locations, water-quality, phytoplankton, and hyperspectral water surface reflectance data. Data...
Exceedance Probability and Predictor Data for Uranium and Radon concentrations in New Hampshire Groundwater Exceedance Probability and Predictor Data for Uranium and Radon concentrations in New Hampshire Groundwater
Statewide maps of the probability of exceeding a given concentration of either uranium (U) or radon (Rn) in New Hampshire groundwater (represented as statewide rasters) are the product of statistical analyses and are available here. The dependent variables in these statistical models were either 1) the natural log of Rn concentrations or 2) a dichotomous variable indicating the...
Results of algal toxin testing from wildlife mortality submissions to the National Wildlife Health Center Results of algal toxin testing from wildlife mortality submissions to the National Wildlife Health Center
This data set is composed of all animals received as a diagnostic submission to the USGS National Wildlife Health Center for which algal toxin testing was performed from November 1998 to January 2018. Birds with a histologic diagnosis of avian vacuolar myelinopathy, a disease caused by the algal toxin aetokthonotoxin, are also included. Algal toxins tested for include brevetoxin
Functional Assessment of Great Lakes Coastal Wetlands 2016-2018 Functional Assessment of Great Lakes Coastal Wetlands 2016-2018
This dataset is the result of a collaboration between the US Geological Survey Great Lakes Science Center and the Great Lakes Coastal Wetland Monitoring Program (CWMP). It contains information on habitat structure, water quality, vegetation, fish, and fish prey in Great Lakes coastal wetlands in the spring and fall from 2016 to 2018. The methods and resulting data mirror the CWMP's...
