Physical Properties of the US ITASE Firn and Ice Cores from South Pole to Taylor Dome
This award supports a project for physical properties research on snow pits and firn/ice cores with specific objectives that include stratigraphic analysis including determination of accumulation rates, annual layers, depth hoar, ice and wind crusts and rates of grain growth with depth. Studies of f...
