Last night the sun set for the last time this season. It is nice that now when we walk to our mid-rats meal at midnight we can see the sun's reflection on the buildings and the Transantarctic Mountains across the McMurdo Sound. The polar summer has begun and the temperatures are rising as well. The snow storm passed and a Hercules plane had landed while I was sleeping: new people came into the station, and we had fresh salad for lunch! Helicopters were also flying and we had more than 20 meters of core to describe. Most of it was composed
of coastal sediments with very few dropstones from icebergs or sea ice, very different from yesterday.
To the right is an example of sediments made by currents (ripples in cross section) overlain by sediments made by waves (the flat layers at the top). After we describe the core, the data is entered in a database system with software called PSICAT. The software also generates a graphic log of the different rocks down the hole. The photo shows Larry Krissek who is entering the data into the PSICAT program.
