The RRS James Clark Ross is on science cruise JR16006 to the Arctic and during this work period will be spending some time outside of the communications satellite that I use to update this web page. More information on this can be found HERE
The James Clark Ross is now at science station B2, having carried out the first station at B1 yesterday evening. Now that the ship is in full science mode the plan for the next few days will be to start a new station at 11:00 and then work through the day and into the evening, completing the work with a final cast at 23:00 before moving off to the next position. The approximate positions for the science stations can be seen on the Dartcom satellite image or on the map HERE.
The Arctic as seen this evening. It has been a glorious day with the noon temperature being about 11 °C but if out of the sun it is rather chilly. In the sun it could be described as almost tropical!
This has to be the smallest drone that I have ever seen! Marie and Emma are calibrating the compass on the drone in preparation for it being flown during the cruise. Once again you can see just how lovely it is here today.
Maintenance work being carried out on the CTD (Conductivity, Temperature and Depth) today due to a bottle developing a slight leak. This instrument is used to collect water samples from various depths, although today it is shallow samples as the water depth here is only about 250m.
Launching a SAPS (Stand Alone Pump System). These instruments are attached to a wire and lowered to the required depth. They contain a pump that is used to pass the water from the depth across a filter and then when it is brought back on board the contents of the filter can be analysed. Normally more that one SAPS is deployed so samples from several depths can be obtained.
The SAPS about to enter the very calm sea. There were several times during today when the surface was just lightly rippled.
The SAPS is deployed up forward. Mid-ships this is the Megacorer being deployed. It is called a megacorer as it takes four samples from the seabed, a normal corer will only take a single sample.
A very excited Mark looking at the results of a sample from the megacorer. Looks like mud to me! Christian is also looking on and supporting the sample.
The pace of science is a varied one. One minute it is all go and then it is all wait! With the megacorer just deployed there is nothing else to do for these scientists other than have a cup of tea and try to warm up. On the starboard side, out of the sun, it was chilly. On the port side two other scientists were basking in the sunshine and not feeling the cold at all.
Satellite elevation remains at about 5º and communications with the ship should remain good for the week to come, with the odd interruption from time to time.
One of our science team is writing a blog and it can be viewed HERE.
