Dataset title: Radiometric Characteristics of Soil Sediments from Shark River Slough, Everglades National Park (FCE) from 2005 and 2006 Dataset ID: ST_OMD_Saunders_002 Research type: Short-Term Dataset Creator Name: Dr. Colin Saunders Position: Research Scientist Organization: South Florida Water Management District, Everglades District Address: 3301 Gun Club Road, MSC 4440 West Palm Beach, FL 33406 USA Phone: 561-682-6309 Fax: 561-682-5892 Email: CSaunder@sfwmd.gov Metadata Provider Organization: Florida Coastal Everglades LTER Program Address: Florida International University University Park OE 148 Miami, FL 33199 USA Phone: 305-348-6054 Email: fcelter@fiu.edu URL: http://fcelter.fiu.edu Dataset Abstract These data represent the results of radiometric dating of soil cores from Shark Slough sites, including FCE LTER sites SRS3 and SRS4 and FCE related site NE-SRS1 from November 18, 2005 to February 26, 2006. Soils from 1-cm depth increments were analyzed for bulk density and stratigraphy. These analyses contribute to a paleoecological study to quantify past changes in vegetation and soil accumulation in relation to past climate variation, fire occurrences and water management.
