Distribution of stable isotopes in surface snow along the route of the 1990 International Trans-Antarctica Expedition
Abstract This paper presents the distribution of average δ D and δ 18 O values for the top 1 m of surface snow for a large area of Antarctica. The samples were collected on the 1990 International Trans-Antarctica Expedition which crossed the continent from the northern tip of the Antarctic Peninsula...
