GISP2 Ions: Deep (D) Core, 111,000 Years

[ Get Data ]

Abstract: This is the ion data set produced by the Glacier Research Group for the GISP2 D
core, from 2 - 3040 m depth. Meters 2 to 96 is B core data. The remainder of
the data is from the D core. Concentration values for each sample are listed
along with the top and bottom depth for each sample. Depths are in meters,
concentrations in micrograms/kilogram (ppb). D core samples were
mechanically cleaned between 96-710m and 1370-1510m. All other samples were
melted using a teflon coated aluminum apparatus which melted the center
portion from a 3.5 x 3.5 cm section of ice.
