Tuesday night was another slightly lumpy one for those living and working on board the James Clark Ross, but things did appear to be better in daylight and shortly after 08:00 the ship stopped and carried out a test CTD cast. CTD stands for Conductivity, Temperature and Depth and enables the scientists to get water samples from known depths in the water column. The test CTD was only to 100m and was to ensure that the equipment was operating correctly and to act as a teaching aid to those involved that had not done a CTD on board the JCR previously. The instrument was only lowered to 100m, so very shallow for us, and was then successfully recovered back on board.
A view of part of the Underway Instrumentation and Control Room (UIC) with a number of monitors that are used to keep those working in the area informed as to what is happening with some of the instrumentation and equipment. You will see a live NavMet screen, which refreshes every second and is ideal for seeing what the conditions are like outside (although one could of course look out of one of the many windows).
The James Clark Ross is going to make a quick journey across the Drakes Passage to King George Island where the science work will start. On our way back to Stanley the intention is to carry out a series of CTD's. Hopefully the sea will be a little calmer. All being well we should arrive in the early hours of Friday morning.
I was passing through the Main Lab today and spotted four gliders out on the benches, being prepared for deployment. Check the Twittter feed for another picture taken today. These instruments are a cost effective way to obtain long term data at a reasonable price as once deployed they are autonomous and will only need collecting at the end of their mission.
Another instrument that we have on board is the VMP, which will be deployed on a wire behind the ship, collecting data as the ship moves at a slow speed. More on this when it is being used. It is being stored in the Rough Workshop.
A rare glimpse into life on board for the scientists. This is cabin 16, one of the four berth cabins on board (there are four of these and fourteen two berth cabins). From each cabin it is possible to access email and work directories and also to phone home. All cabins have their own bathroom facilities.
This evening the sea remains a little bit lumpy but is not too uncomfortable. Hopefully it will be possible to sleep well, although I am sure that my cabin will be making a few noises that I will have to try and ignore. I have discovered a new sound in my cabin, which only occurs when the ship is rolling heavily (more than 15 degrees) and appears to come from inside the door of my fridge!
