For planning purpose (in response to Delphine's message), I just created weekly/monthly climatology of sea ice concentration, sea ice extent (as 15% SIC), chl-a, and wind and some plots of them and iceberg records. The target area 62-67S / 85-110E. Data extracted from Jan-Apr so until week 17 (end of Apr). In addition, I also made two climatology using data from before/after 2016.

The following is, for example, a comparison between AMSR-based SIC in March between 1979-2015 and 2016-2024: sea_ice_concentration_bfr2016_month_3
