| Summary: | Snow pit and snow sample data are included from the Summit area of Greenland from 1987. One 2-meter snow pit was dug and sampled in 1987 with a 3-cm sampling interval. Four 4-meter snow pits were dug and sampled in 1987 with a 3-cm sampling interval. One 6-meter snow pit was dug and sampled in 1987 with a 3-cm sampling interval. Chemistry (H+), stable isotopes (Ca, Cl, Na, K, Mg, NH4, NO3, SO4, MSA), oxygen isotope information (18O), beta surface snow samples were collected from the snow pits. Some general weather observations were collected during the 6-meter snow pit acquisition.
