The James Clark Ross is now on the outer limits of the normal communications satellite. I may, from time to time, be able to update this page with the Daily Position Report, below. There will be no menu or photographs until the ship is back inside the satellite footprint. I also hope that the ship's track will continue to work.
Thursday morning was spent trawling for mud, a lot of which was brought back on to the JCR for the scientists to work through. Upon completion of the last trawl the ship has turned north and is now on passage to science station B17, which is at 81°22'N and 030°00'E.
The passage is not going to be an easy one, with the ship making perhaps five or six knots through the pack ice. The Arctic ice is very different from that found in the Antarctic. It looks thinner, although this is not the case, there is just less of a build up of snow on the top of the floes. I have seen what looks to be thin rotten ice that has then shown to be in the region of 2m thick. At the time of writing this update we have about 188nm to go to get to the next site, but the distance will be greater as we are not often able to navigate in a straight line.
Looking down at some of the rotten ice floes.
Working in ice has a very distinct feel to it. The JCR can travel for a period in what appears to be flat calm seas (assuming one is not looking out of a window) and then suddenly there are shudders and bangs as the bow ploughs through the floes.
Weather today has been mainly dull and overcast, with fog as we moved away from the science station. Late in the afternoon the sun has made a sterling effort and forced the fog and cloud away, and we have a nice blue sky and sunshine. On the horizon is the next bank of fog, so we will be back to poor visibility before too long.
The view from up the radar mast today,
There have been some good seal sightings throughout the day, sadly no more polar bear sightings to report.
Previous updates from this trip The archive only goes to 13th July. Once back in range of comms I will update any days that have interesting data.
