GRIP Acidity, 4000 Years

[ Get Data ]

Abstract: This data set contains the GRIP acidity record, as calculated from electrical
conductivity measurements.

Data consists of:
1) Depth in m below the snow surface at a local maximum in the ECM record.

2) Age at the local acid peak in years BP 1950

3) Number of years of high acidity at the local acid peak.

4,5) The mean acid concentration and background concentration in the years of
high acidity ... View entire text
