Vanadium and boron were detected at high and moderate concentrations in this area. High concentrations for these constituents were detected almost exclusively in samples collected in the Temecula Valley study area.
Geophysical surveying, combined with analysis of sediment cores and radiometric dating were used to describe the likely history of formation of this area.
Explanation of how geologists date rocks (to determine the ages of the Earth, fossils, mineral deposits, and other geologic events) and processes using radiometric dating techniques based on radioactive isotopes of carbon and potassium/argon.
Describes project to identify sources of fecal coliform bacteria by ribotyping to develop the use of Maximum Daily Load (TMDL) values for contaminated stream segments in Virginia.
Brief overview of luminescence dating is presented, including a description of the method, its uses, and proper sample collection techniques. Links to other U.S. laboratories for luminescence dating are also provided.
Plan for an upcoming study, at the microbiological scale, of the benthic communities (including corals) that reside in and around mid-Atlantic canyons, which are located at the edge of the continental shelf.
Homepage for the Missouri District Water-Quality Data & Analysis Section with links to data networks, projects, data availability, mobile laboratories, sampling boat, quality assurance practices, and real-time water-quality data.
Description of project monitoring the status of Greater Glacier National Park Area's grizzly bear and black bear populations using genetic techniques on DNA from bear hair or scats without handling bears, with photos and discussion of methods.
