Dataset title: Isotopic Variation of Soil Macrofossils from Shark River Slough, Everglades National Park (FCE) in December 2004 Dataset ID: ST_OMD_Saunders_004 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 Email: CSaunder@sfwmd.gov Metadata Provider Organization: Florida Coastal Everglades LTER Address: Florida International University 11200 SW 8th Street, OE 148 Miami, FL 33199 USA Phone: 305-348-6054 Email: fcelter@fiu.edu URL: https://fcelter.fiu.edu Dataset Abstract These data represent stable isotopic signatures of selected macrofossils from soil cores from Shark Slough sites, including FCE LTER site SRS3. Soils from 1-cm depth increments were analyzed for macrofossil content (mainly seeds) and seeds were processed for d13C and d15N isotopic signatures. 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.

Seeds were collected from macrofossil analyses (seed ST_SS_Saunders_003) of soil cores. Seeds were inspected under a dissecting microscope and cleaned of rootlets and organic debris. Seeds were rinsed with DI water and oven dried at 80 degrees C. Dry seeds were analyzed for 15N and 13C at the SERC Stable Isotope Laboratory at Florida International University using standard elemental analyzer isotope ratio mass spectrometer (EA-IRMS) procedures. Standards are Peedee Belemnite (PDB) for carbon and air (AIR) for nitrogen. Instrumentation sieves (1000 micron and 500 micron openings), 30x monocular lens microscopes, 65x dissecting microscopes, fine foreceps, balance, Standard elemental analyzer isotope ratio mass spectrometer (EA-IRMS) digital calipers Distribution Online distribution: https://pasta.lternet.edu/package/data/eml/knb-lter-fce/1126/3/4e80542bdeca8e0c456be944733ee4dc Intellectual Rights This information is released under the Creative Commons license - Attribution - CC BY (https://creativecommons.org/licenses/by/4.0/).
