This release contains data from field and laboratory tests conducted by the USGS Groundwater Dating Laboratory between 2014 and 2017 during the development of a new dissolved and gas phase carbon dioxide sensor. The release also contains results of calibration, intercomparison, temperature, humidity, and stability experiments, as well as monitoring studies of CO2 in soil surface gas in the Amargosa Desert during the Toxic Substances Hydrology Amargosa Desert Research Site (ADRS) project, and measurements of dissolved CO2 (pCO2) in Upper Klamath Lake, in laboratory plant mesocosm studies at USGS headquarters in Reston, Virginia, as well as in creeks and streams in Northern Virginia.
Quantify the effect of aquatic and floodplain vegetation on sediment and nutrient budgets along several dimensions of hydrologic connectivity (longitudinally, laterally, and temporally) in the Difficult Run floodplain watershed; Determine if long term trends in anthropogenic nutrients are linked to improvements in submerged aquatic vegetation (SAV) diversity and abundance in other less urban estuaries, as they were in the highly urban, Potomac River; and Habitat evaluation and restoration of coastal wetlands and estuaries in the face of climate change and other stressors such as exotic species and eutrophication.
ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete. If you don't see everything you know is associated with you, a colleague, or your office, please be patient while we work to connect the dots. Feel free to contact sciencebase@usgs.gov.
