Comments

We are progressing very well at a steady speed of around 12 knots. The swell remains low. In the early hours of the morning the ship passed through the Antarctic Convergence Zone where the sea transitions to a much lower temperature. We are far enough south now where icebergs are possible and the ships spotlights were turned on for the first time last night.

Early this morning a small team of expeditioners deployed the first of 9 Argo Float Buoys into the Southern Ocean . These float buoys are high tech. scientific instruments designed to be remotely monitored to retrieve specific data. They are all to be deployed during our voyage south at pre-defined latitudes the first one being at 53 degrees south and the last one at 64 degrees south. The data gleaned from these float buoys will be used to detect and interpret changes in southern ocean circulation as a result of climate change.

Consultation continues between the ship and Davis station in the endeavour to fine tune the plans for our visit. Planning is also well underway for the visit to Mawson.

Cheers,

Tony and Simon
