Explains what biochar is and how it is formed, its potential use in both fertilizer and carbon sequestration, and some of the research questions remaining to be addressed before we can utilize it fully in practical ways.
Boston Harbor/Massachusetts Bay Studies research project conducted as part of Boston Harbor cleanup to predict the fate of contaminants and sediments introduced to Massachusetts' coastal waters from sources that include Boston sewage outfall.
Estimates of uranium resources affected by land withdrawal, effects of previous breccia-pipe mining, water-chemistry data for streams and springs, and potential biological pathways of exposure to uranium and associated contaminants.
An explanation of toxic carbon dioxide emissions at Mammoth Mountain in Long Valley caldera, and a description of magmatic helium discharge at the Mammoth Mountain fumarole with photos, maps, and links to other studies.
Report of research on the Carolina slate belt and gold deposits in Virginia, North Carolina, South Carolina, and Georgia with geologic mapping, mineralogic, geochemical, and fluid evolution studies, radiogenic dating, and stable isotope studies.
Site for programs of the Central Region Mineral Resources Team with links to products, personnel, projects and programs of land stewardship, regional geochemistry, analytical chemistry, geology and resources assessment and remote sensing.
Chloride concentrations in this river have historically been high due to natural saltwater springs and seeps from geologic formations. We monitor the water to help assess the progress of human efforts designed to mitigate this problematic salinity.
Crustal imaging and characterization home with links to projects on earth science technologies including geophysical, geochemical, and isotope studies, online publications and data, and newsletter Minerals News.
