Site with a series of articles showing how chemists and geologists use analytical chemistry to determine the age of the Earth, determine Earth's history, predict volcanic eruptions, observe long-term atmospheric change and study pollution.
Description of the Antarctic Resources Center and links to its workshops and archives of Antarctic maps, charts, satellite images, and photographs produced by the member nations of the Scientific Committee on Antarctic Research (SCAR).
Overview of research to measure, predict, and understand the flow of water through soil and rock between the land surface and the water table with links to field sites, laboratory methods, theoretical developments, publications, and personnel.
Grain-size analysis of marine sediments of the U.S. eastern coast with sampling and lab methods, surficial sediment database in three formats (Excel, Dbase IV, ASCII), and use of geographic mapping tools for visualizing sediment data layers.
Guide to major U.S. environmental statutes and corresponding regulations on air quality, fish and wildlife conservation, cultural and historic resources, solid and hazardous substances, public lands, farmlands, and water resources.
Describes and provides links to USGS research in the location of the estuary and coast of Long Island, New York, to map the sea floor and to study sediment transport, contaminants, and sand resources and coastal vulnerability.
This booklet presents a generalized summary of the nature, workings, publications, and hazards of the common types of volcanoes around the world, along with a brief introduction to the techniques of volcano monitoring and research.
Describes past, current, planned, and experimental USGS programs and processes to permit citizen volunteers to collect geographic and cartographic data and information for incorporation into the USGS topographic map revision process.
The Marcellus shale is a black shale unit in the eastern US. It has economic use as a source of natural gas. Environmental concerns arising from the process of exploiting this resource include water supply and wastewater disposal.
