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.

Emergence of Climate Change Signals for Ecologically-Relevant Climate Variables Emergence of Climate Change Signals for Ecologically-Relevant Climate Variables

Species are expected to shift their distributions to higher latitudes, greater elevations, and deeper depths in response to climate change, reflecting an underlying hypothesis that species will move to cooler locations. However, species response to climate change is poorly understood and species range shifts may be related to climate change exposure. This project was designed to find...

Estimated Densities of Residential Septic Tanks across the Conterminous United States for HUC12, NHDV2 Catchment, and Block Group Scales Estimated Densities of Residential Septic Tanks across the Conterminous United States for HUC12, NHDV2 Catchment, and Block Group Scales

This dataset provides estimates of residential septic tank densities at 12-digit Hydrologic Unit Code (HUC12), National Hydrography Dataset (NHD Plus version 2.1, 1:100k scale) catchment, and 2020 Census Block Group (version 2021) scale for the conterminous United States. Using United States Legacy Census data from the 1990s and the land use classification from the National Land Cover...

Loch Vale Watershed hydroclimate and isotopes of tree-ring cellulose and source-water isotope model Loch Vale Watershed hydroclimate and isotopes of tree-ring cellulose and source-water isotope model

Stable isotopes of water preserved in geologic archives, primarily as oxygen (d18O), have proven critical for documenting Earth’s climatic and hydrologic systems past and present. However, timescale differences of water isotope inputs to proxy systems and the signal embedded in long paleorecords often confound translation to observed hydroclimatic metrics. Here, a unique 20-year dataset...

Lake Michigan Gillnet Lake Trout Assessment 1998-2003 Lake Michigan Gillnet Lake Trout Assessment 1998-2003

Annual spring (May) and fall (late October through early November) gillnet assessment surveys were conducted by researchers at the USGS Great Lakes Science Center (GLSC) in northern Lake Michigan, including the Northern Refuge, between 1998-2023. Total length, weight, sex, maturity, and sea lamprey wounds were recorded for each lake trout and burbot caught in the gill nets. Lake trout...

Lake Erie Fish Community Data, 2013-2023 Lake Erie Fish Community Data, 2013-2023

Assessing the distribution and abundance of both predator and prey (forage) fish species is a cornerstone of ecosystem-based fishery management and supports decision making that considers food-web interactions. In support of binational Great Lakes fishery management, the objectives of this survey were to: provide estimates of densities of key forage and predator species in the western...
