  <Summary>Information from two 2-meter snow pits, five 4-meter snow pits, and two 6-meter snow pits, all dug in 1988 from selected sites in Greenland, includes chemistry (H+), stable isotopes (Ca, Cl, Na, K, Mg, NH4, NO3, SO4, MSA), oxygen isotope information (18O) and radionuclide information.  Surface snow samples were also extracted from the 6-meter snow pits. All snow pits had a 3-cm sampling interval.

The pits and surface snow samples were collected by the Glacier Research Group (GRG), using established protocols to prevent contamination. All data except the oxygen isotope data, which is from the University of Washington, were generated by GRG at the University of New Hampshire.</Summary>
