Abstract

The U.S. Geological Survey and the Geological Survey of Canada recently completed a continental-scale pilot study for a proposed geochemical survey of North American soils. This survey will provide baseline soil chemistry data against which future changes in soil composition can be measured and that can be used by Federal, State/Provincial, and local agencies when making risk-assessment and land-use decisions.

U.S. Geological Survey science supports a thriving Chesapeake Bay watershed economy

U.S. Geological Survey (USGS) science supports the Chesapeake Bay watershed economy by linking natural resources to key economic sectors. The roles of USGS monitoring, data, and analysis inform land-use and resource-management decisions for Department of Interior leadership and other stakeholders.

Divisions of geologic time—Major chronostratigraphic and geochronologic units

Introduction The reports and maps of our Nation’s geological surveys inform and benefit the public, private industry, government officials, and scientists. The use of clear and consistent nomenclature and classifications can improve communication of data and interpretations. Since 1899, the U.S. Geological Survey (USGS) Geologic Names Committee (GNC) has been responsible for defining standards that promote uniform geologic nomenclature and classifications among geoscientists. The GNC periodically publishes a geologic time scale, the “Divisions of Geologic Time,” that serves as the national standard for USGS publications (for example, refer to Orndorff and others, 2023). Authors may use other published geologic time scales, such as those of the Geological Society of America (GSA) or the International Commission on Stratigraphy (ICS), provided that they are clearly specified and referenced. Access to the USGS, GSA, and ICS geologic time scales is also available from the U.S. Geologic Names Lexicon (Geolex) website https://ngmdb.usgs.gov/Geolex/stratres/timescales. The geologic time scale serves a dual purpose by enabling authors to distinguish earth material units by position (chronostratigraphic) and time (geochronologic), as outlined in order of decreasing rank.
