Finnigan MAT 252 massspectrometer coupled to a Kiel II carbonate sampling device
; archiveType changed - was originally Lake sediment (LS)
sample was homogenized prior to division into aliquots for isotope and diatom analyses; Sediment for isotopic analysis was reacted with 2% sodium hypochlorite to remove organic matter and rinsed five times. The sediment was then sieved at 63 mm to remove ostracodes, shell material, and charaphyte sheaths. The flowthrough from the sieve was collected, freezedried, homogenized, and analyzed for carbon and oxygen isotopes
The d18O record from the varved sediment from Crevice Lake is a proxy for hydroclimate, particularly discharge of the Yellowstone River, in Yellowstone National Park. Low d18O values are consistent with high flow of the Yellowstone River and, thus, wet winters with deep snow pack. They also correspond in general with tree-ring inferred estimates of increased precipitation in the YNP region. Prior to 2000 cal BP, decreasing d18O values suggest an increasingly wet climate or a gradual shift to winterdominated precipitation
Comparison of the oxygen-isotopic record with independent measures of climate suggests that the annual moisture balance is the primary isotopic control, with the seasonal timing of precipitation providing a possible secondary influence. High d18O values are associated with dry climate (e.g., evaporative enrichment of 18O) and/or wet summers relative to winters (higher d18O values of atmospheric precipitation).
