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 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 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.

Type II data are considered to be exceptional and should be rare in occurrence. The justification for exceptions must be well documented and approved by the lead PI and Site Data Manager. Some examples of Type II data restrictions may include: locations of rare or endangered species, data that are covered under prior licensing or copyright (e.g., SPOT satellite data), or covered by the Human Subjects Act, Student Dissertation data and those data related to the FCE LTER Program but not funded by the National Science Foundation (NSF) under LTER grants #DEB-9910514, and # DBI-0620409.
