DESCRIPTION:Antarctic ice shelves modulate ice-sheet mass balance through 
 buttressing\, yet the hidden cavities underneath remain largely unexplored
 . In January and February 2025\, a Schmidt Ocean Institute cruise to the B
 ellingshausen Sea collected a ~4\,000 km² of high-resolution multibeam im
 agery\, a set of densely-spaced oceanographic measurements\, 161 hours of 
 remotely operated vehicle footage\, and 864 water\, fauna\, and geological
  samples from Ronne Entrance\, in areas immediately adjacent to George VI\
 , Stange\, and Bach ice shelves. In George VI ice shelf area\, observation
 s were made just few days after large calving event\, in effect enabling o
 bservations of intact sub-ice shelf environment across ~350 sq. km of newl
 y exposed area. This talk will provide an overview of this expedition\, fo
 cusing on geological\, oceanographic\, and ecological processes shaping su
 b-ice shelf environments.
