Six-year record of oxygen and hydrogen isotope variations in South Pole firn
Direct measurements of snow accumulation at stakes near the South Pole over a 6-year period (1958–1963) provide an unusual opportunity to check the reliability of accumulation and annual-layer determinations by stratigraphic and isotopic methods. The results are gratifying. Agreement between inter...

Direct measurements of snow accumulation at stakes near the South Pole over a 6-year period (1958–1963) provide an unusual opportunity to check the reliability of accumulation and annual-layer determinations by stratigraphic and isotopic methods.

All three procedures indicate an average annual accumulation of 7 cm of water at the South Pole over the 1958–1963 interval.
