Science Datasets

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.

Data for Models Estimating Baseflow for Streams Containing Endangered Atlantic Salmon in Maine, USA

The U.S. Geological Survey (USGS) developed a regression model for estimating August mean baseflow per square mile of drainage area to help resource managers assess relative amounts of baseflow in streams with Maine Atlantic Salmon habitat. The model was derived from August mean baseflows computed at 31 USGS streamgages in and near the Gulf of Maine Atlantic Salmon Habitat Recovery Units.

Vibracore CT scans from the San Lorenzo River

This data release contains information on computed tomography images of a vibracore sediment core. This was collected in 2019 near the San Lorenzo River in Henry Cowell Redwoods State Park, California to understand the history of recent vertical incision and floodplain abandonment. The core was split into 3 segments after collection. Each segment was scanned using a Geotek Rotating X-ray CT...
