Radioisotopic data from USGS laboratory in St. Petersburg, Florida
Specific activities of cesium-137 (half life = 30.17 years), lead-210 (half life = 22.3 years), radium-226 (half life = 1,600 years), thorium-234 (half life = 24.1 days), and... -
Concentration of chemical constituents in lake sediments from selected...
The data herein were collected in support of a larger study in Gwinnett County, Georgia, on the potential impacts of on-site waste water treatment (septic systems) on Lake... -
Porosity, dry bulk density, and mass accumulation rates
Porosity, dry bulk density, and average mass accumulation rates, and estimated date of the mid-point of each sediment interval were determined for ten sediment cores retrieved... -
Lake Lanier Biogenic silica
Biogenic silica concentration profiles (in weight percent) for 10 bed sediment cores are shown. Precision and bias were determined by analyses of replicates and reference... -
