The sites drilled on Leg 35 were selected to study the tectonic relationships and interactions between the Antarctic plate and the Antarctic Peninsula, the Scotia Arc, the southern Andes, and the Chile Ridge. Site 322 was drilled on the eastern end of the Bellingshausen Abyssal Plain where it is bounded by the Hero Fracture Zone to the northeast and the continental rise of Antarctica to the south. Site 323 was centrally located on the abyssal plain, about 30 miles west of the Eltanin Fracture Zone and about 150 miles north of the Antarctic continental rise. Site 324 was located on the gently sloping lower continental rise of Antarctica about 160 miles north of Thurston Island, the closest exposed land.

From 1983 until 1989 NOAA-NCEI compiled the NOAA-MMS Marine Minerals Geochemical Database from journal articles, technical reports and unpublished sources from other institutions. At the time it was the most extended data compilation on ferromanganese deposits world wide. Initially published in a proprietary format incompatible with present day standards it was jointly decided by AWI and NOAA to transcribe this legacy data into PANGAEA. This transfer is augmented by a careful checking of the original sources when available and the encoding of ancillary information (sample description, method of analysis...) not present in the NOAA-MMS database.
