Information from 6-meter snow pits dug close to the South Pole in
austral summer 1988-1989 by the Glacier Research Group of the
University of New Hampshire (location - 38 km on grid 90 from South
Pole station - eastern margin of clean air sector) are available.

Major ion chemistry (Na, K, Mg, Ca, Cl, NO3, SO4), oxygen isotopes
(I8O), H2O2, and beta from a 6-meter snow pit covering the period 1955
to 1989 are included. Major ion chemistry for a series of surface snow
samples were also collected on the traverse to the pit.
