Last night, the D-Deck theatre hosted a very interesting presentation by two of our number on autonomous underwater vehicles and their application, past and present in both the Arctic and Antarctic. As Peter K observes 'this included the proposed deployment of 'Nupiri Muka', an autonomous underwater vehicle operated by the University of Tasmania as part of the Antarctic Gateway Partnership project. Similar subs have been used in the high Arctic, but this will be a first for Australia and for this model when we deploy from Davis.'
With the ocean swell overnight picking up, many on board experienced a disturbed sleep and will be glad for calmer seas this evening, albeit without the same likelihood of auroras overhead as there have been the previous few nights.
Today, the watercraft team as well as those expeditioners bound for Davis received instruction on working in sea ice and the use of GPSs by our field training officers (FTOs), whilst the ship's crew and voyage management prepped for the deployment of two buoys tomorrow morning that, once in the drink, will drift with the currents whilst sending back to the Bureau of Meteorology data on atmospheric pressure and sea temperature. Activated on the heli-deck early this afternoon, both are sending a strong signal back to the Bureau which is a good sign.
Operational planning for the Casey resupply continues in consultation with our colleagues at station who are no doubt busy in their own preparations for resupply, additional as they are to regular station function and their summer operations programme.
Back on board.. for those not engaged in planning, onboard science projects or trainings, today passed much like the last.. beans being peeled, books being read, beanies being stitched, naps being had and tea being sipped.
Regards,
Voyage Management.
