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.

Towards an integrated theory of body size distributions, life history and functional traits, and environmental flows in freshwater ecosystems Towards an integrated theory of body size distributions, life history and functional traits, and environmental flows in freshwater ecosystems

Efforts to quantify and explain individual size distributions (ISD) are prominent in ecological research and potentially for applications to management which increasingly consider ecosystem-scale objectives. We use a nation-wide database of individual size measurements for United States stream fishes paired with species’ traits and test for direct and indirect effects of traits, flow...

Model and Data Resources Supporting Water-Quality Modeling of Hydrologic Systems Model and Data Resources Supporting Water-Quality Modeling of Hydrologic Systems

This dataset provides detailed information on availability of model resources (including models and datasets) that support the modeling of six key water-quality constituents (or constituent categories) across the hydrologic system. In addition, resources associated with nine “cross-cutting” topics for modeling water quality are included, with “cross-cutting” defined herein as having...

Fish assemblages and habitat conditions of the Saint Lawrence River and its Tributaries Fish assemblages and habitat conditions of the Saint Lawrence River and its Tributaries

Biodiversity measures provide insight into ecological processes like productivity and ecosystem stability, and rare, vulnerable species are a major component of freshwater biodiversity. This data release provides the data used to address multiple ecological questions about fish and habitat conditions throughout a large section of the St. Lawrence River Valley. More than 140,000 fishes of...

Ungulate Migrations of the Western United States, Volume 5 Ungulate Migrations of the Western United States, Volume 5

This is the data archive for the publication Ungulate Migrations of the Western United States, Volume 5 and includes the collection of GIS map files that are mapped and described in the report. These map files are meant to provide a common spatial representation of the mapped migrations and seasonal ranges. This data release provides the means for ungulate migrations to be mapped and...

Distance matrices and river-network crosswalks for the Geospatial Fabric v1.1 to support data-driven models of water quality in U.S. rivers Distance matrices and river-network crosswalks for the Geospatial Fabric v1.1 to support data-driven models of water quality in U.S. rivers

This data release contains hydrologic network information to support national modeling of water quality in streams and rivers, including distance matrices that represent the spatial relationships among modeled river reaches. These data can be used as inputs to data-driven models that leverage information about spatial proximity to make predictions of water quantity or quality. The...
