  • Reflections on radar

    Hello from Camp E! Just thought I’d share with you some initial results from the geophysical acquisitions we’ve been doing. While bad weather got in the way of our camp move for a few days, it was no big hindrance to the progress of geophysics, which has mostly been about radar for now. We’ve currently got around 450 km of line data in the bank, allowing us to shed some light on the internal structure of the Larsen C ice shelf.

  • Moving again

    Work at Camp C went very well, the borehole was drilled and televiewed and we collected many more kilometers of radar data. We also dug a two meter deep snow pit for sampling the density, temperature and water content of the firn every five centimeters from top to bottom. By excavating an adjacent pit we were also able to take photographs with the fifteen centimeter separating wall backlit by the sun making the various ice layers within the snow clearly visible.

  • Boring holes

    A major part of MIDAS’ field programme involves investigating the internal structure and physical properties of the Larsen C Ice Shelf, and in particular how these properties are influenced by the presence of intermittent surface melt ponds. In order to measure the shelf’s 3D temperature, via thermistor strings, and density, via optical televiewer logging, we first need to gain access to its interior.

  • Across the ice to Camp C

    So, after three tent-bound days (I finished reading Anna Karenina!), plus one further day of digging out sledges and skidoos, we finally set off for Camp C yesterday. After a 6:30 am rise we were finally ready to set off just before noon. Initially, the low cloud and drifting snow meant that it was like travelling inside a ping pong ball, but when the sun came out, the surface sparkled like diamonds, and we could enjoy the ride. Heading west, away from the mountains of the peninsula and towards the ocean, we travelled for over eight hours.

  • Preparing to move

    We are coming to the end of the work at the first camp and next need to move a hundred kilometers downflow towards the edge of the ice shelf. The move will be a major logistics exercise: tents to take down, equipment to pack and a very long day’s travel, seven people on four skidoos with lots of sledges behind. For this we need very good weather and the forecast tomorrow is for 45 knot winds!
