Antarctica - Wilkes Land snow / firn temperatures
Measurements of temperature within the snow / firn cover in Wilkes Land East Antarctica were made along the routes of oversnow traverses operating out of Casey (66.6 S 110 E). In general, measurements were made at a nominal depth of ten metres as a first estimate of mean annual surface temperature o...
