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.

This data represents samples of algae from Upper Klamath Lake Oregon, during the summer of 2016. Data were sampled from the lake using standard protocols and then shipped to the remote sensing laboratory at the National Institute of Standards and Technology (NIST) for analysis on the hyperspectral microscope at NIST.
This dataset is a collection of hyperspectral imagery profiles of 13 common algae associated with Harmful Algae Blooms (HAB). Data were retrieved from a hyperspectral microscope at, and with the cooperation of, the National Institute of Standards and Technology. Samples were collected from USGS water quality sampling efforts, and were also purchased from commercial vendors of biological materials. Data are shown in basic hyperspectral imagery form, transformed into the first derivative and corrected with a flat field algorithm to account for variations in locale lighting conditions.

This data set presents chemical data for water column samples from USGS and Klamath Tribe sites in Upper Klamath Lake, Oregon. Surface water, bottom water and integrated water samples were analyzed for major cations including metals and anions including chloride, sulfate, alkalinity, phosphate silicate and nitrate. Values for pH ranging from 7.3 to 10.0 are also reported.
