The Met Office and assorted floating devices – Friday 31st October 2008

As part of the fun we have out here, lots of people ask for samples to be taken. Some want water, some want the water filtered to look at plankton etc. but some let us play with expensive bits of hardware like the nice Met Office boys at Exeter.

As we are at the Southern turn of the transect at 28degrees South/25 degrees West today which is before we turn south west and then head straight for the Falklands, we have been requested to deploy (posh word for chuck! No honestly, we lower then in by a crane, Jon) some buoys and floats into the water.

Argo floats

Argo floats

The picture shows in the foreground the very expensive Argo floats, these have a CTD (conductivity, temperature, depth) sensor on them and have the technology to sink to 200m, rise back up to the surface and then send the data back to the Met Office people. Clever bit of kit that will drift around and send results back from wherever the currents take it. These Argo buoys are part of the global Argo float array. Many countries deploy these as part of their oceanographic research programmes.

So that’s the long yellow thing in the photo. Behind it is a drifting buoy, which has a drogue attached to take it with the ocean currents. Both the Argo and global drifters are key to observing ocean systems that are contributing to the Global Climate Observing System and the Global Ocean Observing system (GOOS).

So we have deployed 2 of each so far then one more tomorrrow and Sunday. This gives a good cluster around the 28South position.

Spook-tastic – Friday 31st October 2008

Halloween fun

Halloween fun

It’s Friday 31st October and it’s… Halloween.

Scary monsters on the JCR or is it just men having a bad hair day… you decide! Personally I blame the doctor.

Gordon Ramsey eat your heart out – Friday 31st October 2008

 

Pasteurization of seawater to contribute to a global series of nutrient reference materials

Pasteurization of seawater to contribute to a global series of certified nutrient reference materials

Ingredients:

400 litres of seawater, plus a drop or two of perspiration to taste. Cook for 12 hours minimum at 85-90C, then store in a dark place indefinately.

Colours in the sky – Friday 31st October 2008

Sky phenomenon

Sky phenomenon

This morning it was quite overcast and with rain in the air, but with a couple blue patches poking through the gloom. On looking up we noticed this rainbow effect but very high up in the clouds, most strange. There was no rainbow before or after so a strange phenomenon…

Physics on AMT – Thursday 30th October 2008

Since the beginning of the AMT, the programme was centred around optics, satellites and ocean biogeochemistry. It was this that established the AMT as one of the world’s leading oeanographic programmes (and hence data sets), which we are now able to call ‘long-term’ as we enter this new phase with Oceans 2025 funding for the next 5 years. The big gap in our knowledge was always recognised as being the very limited ocean physics studies that were carried out during all the earlier cruises. However this has now been remedied to a large extent with the inclusion of the National Oceanography Centre (NOC) on-board team of Jo and Stuart, with invaluable help and guidance from John Allen up to the Azores. Although to be factually correct Jo has just started working at Proudman Oceanographic Laboratory (POL).

The output is some excellent data which is near real-time and enables us to study the outputs from the Moving Vessel Profiler (MVP) and Acoustic Doppler Current Profiler (ADCP) to see what is going on in the water column and how that links to the chemistry and biology being studied in the main labs.

How to worry a Principle Scientific Officer – Tuesday 28th October 2008

Conductivity, temperature and depth profiler (CTD)

Conductivity, temperature and depth profiler (CTD)

So here we sit here at 1000 local time, an hour behind you in the UK. Its a gently rolling sea with blue sea, blue skies (have you looked at the webcam?) and a very pleasant morning. We have carried out the regular 2 CTD’s to 300m pre-dawn and today is one of the 2 deep CTD’s that we will sample in the Southern Atlantic gyre region down to the ocean floor, a few thousand metres below the sea surface.

Webcam – Monday 27th October 2008

For those wanting to look out the front window of the Bridge on the James Clark Ross as we steam southwards then the webcam can be found at:

And yes I can confirm its sunny today, at last!

Parottnapping on the high seas – Monday 27th October 2008

In a final desperate measure before meeting their judgement the dastardly Pollywogs Parotknapped the Nutrient Parrot. This chap is an old hand of 24 years at sea and far too many cruises to even start to discuss. The parott is/was cared for by the Chief of Police who is now quite distraught at this turn of events.

Poor Polly

Poor Polly

However, despite this intervention he followed government guidlines and refused to negotiate with the terrorists who had taken the bird. Ransom posters were displayed and even after the event the parott has yet to be released. However it is now in the hands of the ships underground secret police led by Polly Mann who are confident they will find the bird and the criminals.

Any infomation please contact your local station, or ring Crimestoppers on 065346671882.

Neptune Cometh to the JCR – Sunday 26th October 2008

After crossing the line very early of friday morning, the arrival of The King was delayed until 1530 to allow for scientific activities and also for Neptune to digest his lunch properly before all the excitement began.

Traditionally the ‘unclean’ ones. who have not crossed over into Neptunes realm. are know as ‘Pollywogs’ and those who have are the ‘Trusty Shelbacks’. The sins of the Pollys are collected and a set of charges are put together, which they have the option to plead guilty or alternatively guilty. Either way they are stuffed!

Equator crossed – Friday 24th October 2008

At 0102 hours this morning the RRS James Clark Ross and the AMT-18 team crossed the equator at 25 degrees West and headed into the Southern Hemisphere. A light swell and a starlit night welcomed us over.

Currently its 0530 and we are carrying out the first sampling CTD station of the day at 29 minutes south of the line.

Neptune no doubt still sleeping and dreaming of his visit later today.
