Rothera to Cape Disappointment

On February 3rd, we departed Rothera on a BAS Twin Otter and flew 250 miles northeast to our field site at Cape Disappointment – a near-perfect vantage point to watch how this region might evolve during this warmer-than-average late summer period. The camp is set near the summit of a small dome of rock and ice (about 2 miles across and 1000 feet elevation) set at the end of a narrow low peninsula jutting out into the Larsen B embayment. To the north is a vast flat frozen ocean where the Larsen B ice shelf used to be – now filled with 4-year-old thick ocean ice and tiny iceberg fragments from the collapsing glaciers that formerly fed a 700-foot-thick ice shelf. To the south we can see the smaller remnant ice shelf filling Scar Inlet – among the northernmost remaining ice shelves on the continent, and poised now to collapse or break apart sometime in the next few austral summers. Perhaps this one.

As I write this, we’ve been here for 6 days now, with weather alternating between intense burning sunshine and blinding windstorms. Both conditions are key parts of setting the stage for a breakout of  the frozen ocean or collapse of the ice shelf. During our good weather windows, we set up camp and installed 7 instrument sites — a radar, several stereo camera pairs, seismometers, and  a listening device called an ‘infrasound array’.

  1. So glad to hear from you all. We can’t wait to hear and see what happens to the ice shelf. Erin- we leave for Tanzania on Wednesday, Feb 17. We’ll have wifi where we are staying. Keep up the reports.
