myUSGS offers an access-controlled online suite of science collaborative tools, ideal for use by USGS scientists and their research teams as well as by other communities of practice involving USGS and its partners.

The Hazards Data Distribution System (HDDSExplorer) is an event-based interface that provides a single point-of-entry for access to remotely sensed imagery and other geospatial datasets as they become available during a response.

The GeoPlatform provides shared and trusted geospatial data, services, and applications for use by the public and by government agencies and partners to meet their mission needs.

An online resource supporting terms in a 'broader than' and 'narrower than' structure in ecological and biological sciences. It encompasses terminology that depicts human and non-human life, and their interactions. Concepts are included from the life sciences; environmental sciences; aquatic sciences and fisheries; ecotourism, fire ecology and management; and sociology.

The National Vegetation Classification (NVC) is your guide to inventorying plant communities. The standard allows users to produce uniform statistics about vegetation resources across the nation. CSAS&L actively participates in the development of this important standard through our involvement with the FGDC Vegetation Subcommittee and the ESA Vegetation Panel.

We conduct post-fire debris-flow hazard assessments for select fires in the Western U.S. We use geospatial data related to basin morphometry, burn severity, soil properties, and rainfall characteristics to estimate the probability and volume of debris flows that may occur in response to a design storm.

The U.S. Geological Survey applied the SPARROW model to assess the loads delivered in 2002 for estuaries and coastal waters along the Atlantic Ocean and eastern Gulf of Mexico.

The Alkalinity Calculator will analyze the titration curve and calculate the alkalinity or acid neutralizing capacity (ANC) of the sample using one or more of several different methods. Alkalinity is for filtered samples, while ANC is for unfiltered samples. The results will be displayed in tabular and graphical form.

A map app to get recharge values from streamgage locations in Pennsylvania. Development of this app is described at the Related Science page.
