Snow Pit Data from Greenland Summit, 1989 to 1993



Chemistry and isotope information from snow pits dug at the Summit area of Greenland, 1989-1993 includes major ions (Na, K, Mg, Ca, Cl, NO3, SO4), oxygen isotopes (18O) and H2O2. Four snow pits were dug and sampled in 1989, three snow pits in 1990, two in 1991, one in 1992 and one in 1993. All snow pits had a 3 cm sampling interval except the snow pits in 1990, which had either a 3 cm or 5 cm sampling interval. Chemistry and isotope information were obtained from each of the snow pits. The pits and surface snow samples were collected by the Glacier Research Group (GRG), using established protocols to prevent contamination. The samples collected in 1991 were analyzed at the Greenland Ice Sheet Project Two (GISP2) drilling camp. All data except the oxygen isotope data, which is from the University of Washington, were generated by GRG at the University of New Hampshire.
