GISP2 Ions: Deep (D) Core, 100,000 YearsEntry ID: NOAA_NCDC_PALEO_GISP2_DEEPD
Abstract: This data set contains the GISP2 major ion concentrations in parts per billion
(ppb) by mass. Blanks (999999) in chemical species represent samples below
detection limits. Firn samples were cleaned in the freezer by hand scraping
and placed in a pre-cleaned container. The pieces were kept frozen until
analyzed. Samples from 96 meters to 200 meters were cleaned by rinsing with
milli-Q water. Samples below 200 meters were cleaned by hand scraping after
Ions sampled include:
