Stable Isotopic Investigatino of Basal Ice, Taylor Glacier Antarctica
Abstract Only Basal ice, debris-rich ice at the base of a glacier or ice sheet, contains particles of ground up material from the rocks and sediments the glacier flows over. The stable isotopic ratio of debris-rich ice can vary in response to the type of debris entrainment processes including direct...
