At Noon today the James Clark Ross was 63 nautical miles from Rothera.  Sadly this was not good news as the pack ice that is blocking our route to the base was just as unforgiving today as it has been on our two previous attempts to break through it.

At one point this afternoon the ship was stopped against a pressured section of pack and just ahead of that,  beyond our reach,  was a flow of ice at right angles to us,  looking almost like a lava flow.

The image above shows the ship in relation to Rothera and Adelaide Island (which we sighted at about 43 miles this morning.

On Thursday I had a telephone call with Kilkeel Primary School in Northern Ireland and took questions from almost all of the sixty pupils.  Sadly I had to cut the call short due to work but I have been sent the remaining questions as weekend homework by the teacher.  For those not sure of where we are, it is being pointed out on the inflatable globe.  The children were excellent with their choice of questions.

This evening,  some twenty-four hours after entering the pack ice the James Clark Ross is heading back out of the ice and into open water.  The weather is changing with the wind picking up and this may,  over the course of the weekend,  have an effect on the ice.  Once back in open water the swath bathymetry survey will continue.
