In the summer Summit camp has a higher population (27-50 people). The fluctuation of population is from the scientists coming and going. Most of the projects I helped sustain through the winter will be coming up to do upgrades and changes to their equipment.
Temperatures are warm enough to melt snow on darker surfaces and we end up with interesting icicles.
This is an firn ice core that was drilled during my first week back on station. These scientist are looking at snow density and compaction in the firn layer. The firn layer is where the snow has not been compressed into hard ice yet. Solid ice forms about 40 meters down.
Another science group to pass through already is the German seismograph guys. We dug a huge hole for them (2 meters x 2 meters x 3 meters) so they could relocate their equipment closer to the surface (the old trench was getting too deep).
Here is the new trench.
Some of the seismic equipment. This can detect icebergs calving off the Greenland ice sheet as well as earthquakes all around the world.
The mouth of the seismic trench.
Weather has been pretty good after last weeks wind storm.
The greenhouse has been unburied from its winter drifting (and now you can actually see it).
It's been very warm (-10 to 10 F) and the food has been fantastic (there is a cook in the summer and she is awesome)! More updates to come now that the busy first week is over!
