[MIS14-16] Ocean and material circulation in the southern part of the Australian Antarctic Basin in 2018/2019 summer - preliminary results from Kaiyomaru KY18-04 cruise
Keywords:Shelf circulation, Bottom water formation, carbon circulation
With these questions in mind, R/V Kaiyomaru, Japan Fishery Agency, conducted a research cruise in the basin, in proximity of its seasonal ice edge, from December 2018 to March 2019. This part of the basin has been observed by an Australian team in 1996. At the time of writing, more than 40 stations have been occupied for CTD and LADCP observations and bottle sampling, more than 80 XCTD probes have been deployed. Preliminary analysis shows the changes in the bottom water masses. The Figure below shows the CTD/LADCP/sampling stations (black dots) and XCTD deployments (crosses) for Leg1 (5 Dec 2018 to 16 Jan 2019) with AMSR2 derived ice concentration, which is a combination of west of 90E (observed on 17 Dec 2018), between 90E and 107E (24 Dec 2018) and east of 107E (31 Dec 2018). In the talk, the latest results and its outlook will be discussed.
