Comments

This morning the last of the CTD casts for genomic analysis of marine microorganisms near the seabed was taken in depths of a little over 3000m. The Continuous Plankton Recorder is now being towed behind the ship on the second of three deployments for the return journey. During each deployment it collects zooplankton from the near surface waters on a silk spool that is gradually wound past the opening in the CPR using a simple clockwork mechanism driven by a small propeller. When analysed, differences in the zooplankton community over the 400 mile deployment can be identified. Everyone busy on board processing data, collating reports and preparing paperwork for arrival in Hobart. Regards, Martin and Sarah.
