Abstract:
Annual volcanic sulfate mass deposition rates from the West Antarctic Ice Sheet (WAIS) Divide ice core project for the time period 12.68-13.20 ka BP on the annual-layer counted WD2014 chronology and transfered to the Greenland GICC05 chronology using common volcanic markers. The reconstruction is based on sulfur measurements employing high-resolution continuous flow analysis coupled to inductively coupled plasma mass spectrometry performed at the Desert Research Institute (Reno, NV, USA). Volcanic eruptions are detected when annual sulfur concentrations exceeded the background concentrations + 2 times the median of the absolute deviation. Background concentrations are estimated using a 101-year running median. Volcanic sulfate deposition rates are calculated by subtracting the background concentrations from total sulfate concentrations using thinning corrected estimates of mean accumulation rates at the ice-core site.
