Abstract:
Reports on ATLANTIS Cruises 280 and 281 to the New England Seamount Chain are combined here. . A continuous bathymetric survey was run on both cruises, with profiles across several seamounts. A series of dredge and camera stations were made. They are dicussed in this report. Also included are photographs representative of each camera lowering and photographs of dredged material.

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1989 NOAA-NCEI compiled the NOAA-MMS Marine Minerals Geochemical Database from journal articles, technical reports and unpublished sources from other institutions.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