In view of the fact that thick sections of Neocomian and Jurassic limestone were found in the region off the Bahama Islands (Holes 99A, 100 and 101) a hole was selected for drilling between New York and Bermuda at a position where knowledge might be gained about the structure and composition of the lower continental rise hills. In addition, such a hole would ascertain the age of the crust.

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1989 NOAA-NCEI compiled the NOAA-MMS Marine Minerals Geochemical Database from journal articles, technical reports and unpublished sources from other institutions.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