Recovered buoy, replacement buoy on the right

Today has been full of events. The CTD this morning, and then the recovery of the PAP mooring.

Cruise JC071 – CTD recovery

CTD recovery

We were all disappointed that the weather did not allow the recovery or the CTD to go ahead yesterday, but today the weather is definitely improving and the first CTD which will go to 4000m was put in the water just after 6am.

Cruise JC071 – preparations and procedures

CTD – conductivity, temperature and depth instrument

Today is a day for final preparations and practice procedures while the PSO finalises the work plans to ensure the various groups of scientists and technicians will get the samples they need at the times they need them.

Our cruise to the PAP site has finally come to an end and after a successful couple of days at the Porcupine Seabight the James Cook steamed back to Falmouth. Although everyone was excited by the prospect of fresh fruit, crunchy vegetables, and yes, family and friends too, the joy of returning to “normality” is always accompanied by some sadness.

A translucent sea cucumber (Peniagone sp.)

Ahoy, everyone! A couple of days ago, we finally left the Porcupine Abyssal Plain after a very successful sampling regime of megacoring, trawling, and the deployment of various other instruments over the past few weeks.

Quite a few of the samples being brought up from the deep are being preserved in ethanol for DNA analysis when we’re back on land.

The days when we take the trawl samples seem to be a somewhat confusing mixture of sleeplessness, excitement and a lot of hard work! For me, these trawls are really the reason I’ve been out here for the last two weeks as I gather samples of abyssal fish for my PhD.

The box corer full of mud

The deep sea is a reservoir of unknown biodiversity, particularly among invertebrates living inside the mud with many species new to science and in many ways rivalling the discovery of new insect species in rainforests.
