The survey collected over 1800 images of the sea floor on the continental shelf and slope in the Mertz Glacier region, including in the area previously covered by the Mertz Glacier tongue. There were 75 successful camera deployments and a further 7 stations where images were of poor quality but may still provide useful information.
