Stalagmites dated by U-Th Series, and isotope data collected on a Finnigan MAT 252 using a Kiel II device. Analyses of Cold Water Cave stalagmite 1S are tabulated in Dorale et al. (1992). The total length of SV-1 = 635 mm; SV-2 = 560 mm; MC-28 = 317 mm; CC-A = 311 mm. #-------------------- # Publication # Authors: Denniston, R.F., L.A. González, R.G. Baker, Y. Asmerom, M.K.

Alexander # Journal_Name: The Holocene # Published_Title: Speleothem evidence for Holocene fluctuations of the prairie-forest ecotone, north-central USA # Published_Date_or_Year: 1999 # Volume: 9 # Pages: 671-676 # Issue: 6 # Report_Number: # DOI: 10.1191/095968399674716399 # Full_Citation: # Abstract: Carbon and oxygen isotopic trends from seven Midwestern speleothems record significant offsets in the timing of middle-Holocene vegetation change. Interactions of dry Pacific and moist Gulf of Mexico air masses maintained a sharp moisture gradient across Iowa, Minnesota, and Wisconsin such that the arrival of prairie was offset by 2000 years between caves and pollen sites located only 50 km apart. Oxygen isotopes shift concomitantly with carbon in most cases, although these changes are believed to represent increased evaporative enrichment of 18O prior to infiltration during the prairie period. #-------------------- # Funding_Agency # Funding_Agency_Name: US National Science Foundation # Grant: ATM-9731138 #-------------------- # Funding_Agency # Funding_Agency_Name: Geological Society of America # Grant: #-------------------- # Funding_Agency # Funding_Agency_Name: National Oceanic and Atmospheric Administration (NOAA) # Grant: NA366PO238 #-------------------- # Funding_Agency # Funding_Agency_Name: Cave Research Foundation # Grant: #-------------------- # Funding_Agency # Funding_Agency_Name: Richmond Area Speleological Society # Grant: #-------------------- # Funding_Agency # Funding_Agency_Name: Cave Conservancy of the Virginias # Grant: #-------------------- # Funding_Agency # Funding_Agency_Name: National Speleological Society # Grant: #-------------------- # Funding_Agency # Funding_Agency_Name: University of Iowa # Grant: #-------------------- # Site_Information # Site_Name: Spring Valley Caverns # Location: Minnesota # Northernmost_Latitude: 43.75 # Southernmost_Latitude: 43.75 # Easternmost_Longitude: -92.41 # Westernmost_Longitude: -92.41 # Elevation_m: 397 #-------------------- # Data_Collection # Collection_Name: SVC-1 # First_Year: 8517 # Last_Year: 0 # Time_Unit: cal yr BP # Core_Length_m: # Parameter_Keywords: carbon isotopes, oxygen isotopes # Notes: #-------------------- # Chronology_Information # Chronology: Uranium-Thorium # Chronology_Download_Resource: https://www.ncei.noaa.gov/pub/data/paleo/templates/noaa-wds-paleo-uth-terms.csv # Chronology_Download_Description: Uranium-Thorium terms and definitions. # Chronology_Notes: Dated using TIMS.
