Rough seas and science finally starts

The core aim of DY030 is to collect samples and data to understand how the chemistry and biology of the Celtic Sea link together to drive healthy and productive conditions, as well as how those conditions might change with climate change. After sailing we experienced some weather more associated with March than May – a number of scientists took to their cabins or just sat on deck staring at the horizon wishing the waves away! Those with their sea legs carried on and continued preparations in their various laboratories on the ship waiting for the science to start.

We eventually started work on the 6th May at one of our main Benthic Process sites – Benthic G. First up is always some CTD work even on a benthic sediment sampling research cruise. CTD (Conductivity, Temperature and Depth) is the stock instrument of any oceanographic cruise and enables us to understand the water column structure using a number of on-board sensors and collecting water samples from per-determined depths for subsequent analysis. After a slow start it is always nice to get the first sampling underway.
