This week I got out on one of the science boats Nimrod. The marine team at the Bonner Laboratory at the southern end of the base make regular boating/diving trips in the local area to take water samples and to lower a Conductivity, Temperature and Depth(CTD) instrument. On a morning off I tagged along on a trip into South Cove.The CTD Instrument is lowered to as much as 500 metres then hand winched back onto the boat.
On our trip the instrument depth was 300 metres so we took turns at winching 100 metres of line each/
We also took a number of water samples from 15 metre depth into ultra -clean containers for analysis back at the lab.
