Mount Discovery as seen across the sound from McMurdo Station.
In one of Chris Shuman's (black hat) snow pits, helping to sample layers for isotopic analysis.
Internal layers in firn (old snow) as seen from a back-lighted snowpit wall. Physical and chemical properties of such near surface layers can often be linked to known climate events. This aids in the understanding of similar properties observed in much deeper ice core records, for which the climate events are generally unknown.
U.S. Coastgaurd Icebreaker "Polar Sea" taking scientists and support personnel on a cruise through the icebreaker channel out to the open sea. Every year the icebreaker clears a channel through the sea ice into McMurdo sound so that a large cargo ship can dock at the end of the season, prior to the onset of winter.
