The first CTD cast, measuring conductivity-temperature-depth from sea surface to sea bed and simultaneously collecting water from 24 depths was completed yesterday evening. After this we deployed an Argo float - an autonomous CTD controlled by an on-board computer that sinks and rises through the water-column measuring as it goes. The float will drift around for about 4 years sending back data by satellite and is part of a global network providing information on the world's oceans. We then moved about 25 nm south to deploy an acoustic mooring on the sea-bed at about 2000m which will record the calls of whales, with the data used to estimate the presence, relative abundance and movement of the different species in the region. We are now in transit towards the SAZC mooring and have the CPR deployed to our stern. Regards, Martin and Sarah.
