The RRS James Clark Ross has remained at Marian Cove, King George Island overnight and science has continued throughout the period. Every time there is a scientific deployment it is given a number and I have just checked the Bridge Science log and can see that we are about to carry out event 40. The ship will often move to slightly different locations, all so far within Marian Cove, between events.
As part of the ICEBERGS cruise the JCR has on board the Shallow Underwater Camera System (SUCS) and last night a number interesting pictures were taken. This one has sponges, sea urchins, brittle star, sea squire and crinoid. Picture Dave Barnes/BAS
A seastar. The SUCS is designed to be able to measure what is in the frame and this seastar is estimated to be about half a square metre. Picture Dave Barnes/BAS
Part of the science is using the plankton net. It was chilly this morning when I took this picture but as the day has progressed the sun has finally broken through the cloud and it has been a lovely afternoon and evening.
I am in daily contact with Signy base and last night they enjoyed their first bar-be-cue, although their weather did change from bright and sunny to snowing but that did not put them off.
This is a Wave Glider being prepared for deployment and from what I have been told is an amazing piece of remote sensing equipment. The section out on deck will float on the surface and suspended below it, some 7m, are a set of wings that use the action of the waves above to propel it. These have covered vast distances, across the Pacific Ocean, and can be out at sea for up to a year. This one has a number of meteorology sensors fitted and can travel at up to 2 knots. It keeps in touch with the science team via Iridium satellite and they can direct where it goes. Whilst it has a battery on board it has two large solar panels to allow it to roam for long periods. Once it is fully constructed I will get a few more pictures.
With the sun now shining there is a beautiful backdrop to the science work being carried out.
What appears to be a frozen waterfall on some of the exposed rock on King George Island.
Alethea, one of the scientists on board, filtering sea water taken by the CTD and looking for plastics in the water. This is an important part of research these days as there is a growing concern about the way plastics are used and disposed off and that they can travel throughout the oceans of the world.
It is not all work but there is time to relax and here Nicole and Pips are busy with some crochet in the bar this afternoon.
Looking at the glacier in Marian Cove this afternoon.
