| Objectives | Cruise JR59 was originally planned as a follow-up to the highly successful cruise JR48
in the 1999-2000 season. It had been intended to conduct swath bathymetric survey and TOPAS profiling in the area of the former Larsen Ice Shelf. About a month before departure it became clear that the pack ice in the northwestern Weddell Sea was not going to recede sufficiently to allow ship access to that area. Accordingly it was decided to work on the west side of the Antarctic Peninsula, from southernmost Marguerite Bay out to the continental shelf edge at 71/W. This cruise forms part of the BAS SAGES programme (Signals in Antarctica of Global changES) and the AFI bid "Ice-rafted debris on the Antarctic continental margin and the dynamics of the Antarctic ice sheet" led by Julian Dowdeswell and Carol Pudsey. |
