GISP2 Volcanic Markers, 110,000 YearsEntry ID: NOAA_NCDC_PALEO_GISP2_SULFATE
Abstract: This data set contains the volcanic sulfate record in the GISP2 core on the
Meese/Sowers timescale. Each sample is approximately bi-annual for the last
~12,000 years with a consistent increase in the time covered by each sample to
around 50 years/sample at 110,000 years ago. The volcanic sulfate record is
derived by applying an empirical orthogonal function (EOF) analysis on the
entire ... glaciochemical time series (Mayewski et al., 1997a). EOF 5 was found to
explain 12% of the variance in the sulfate record, but it did not significantly
explain the variance in any other chemical species. The excellent correlation
in the EOF time series and the volcanic sulfate record for the last 9000 years,
based on sulfate residuals over a robust spline (Zielinski et al.,1994a)
indicates that EOF5 is an indicator of volcanic sulfate deposition over the
last 110,000 years.
