A total of 36 coring stations were worked during the cruise of which twenty-five were successful. Both piston and free-fall gravity coring techniques were employed and the cores were extruded and rough logged on board ship as soon as they had been taken. Twelve dredge stations were occupied on the cruise, all of them lying in the Peake Deep area, and nine were successful.

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1989 NOAA-NCEI compiled the NOAA-MMS Marine Minerals Geochemical Database from journal articles, technical reports and unpublished sources from other institutions.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.
