This site is designed to provide information on federal interagency and cooperative developments related to coastal sand and gravel resources and management issues along the Atlantic continental margin.
Manual of chemical sediment analysis using Coulometer and CHN Analyzers to measure carbon content, spectrometric analysis for biogenic silica, and radiochemistry to measure isotopes. Includes techniques,sample preparation, and safety procedures.
This report presents geochemical data generated during mineral and environmental assessments for the Bureau of Land Management in northern Nevada, northeastern California, southeastern Oregon, and southwestern Idaho, along with metadata and maps.
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.
Information on aquifers in upstate New York which consist of unconsolidated deposits of sand and gravel that occupy major river and stream valleys or lake plains. Links to aquifer maps at scales 1:24,000 or 1:250,000 and cooperative publications.
