Abstract:
Since 1954 the Blake Plateau has interested the geophysical group at Woods HOle. Early cruises gathered data on this region incidental to other work. It became apparent that the area was worthy of more intense study. Questions about the bathymetry and underlying structure had been raised. This is a report of the most recent cruise undertaken to study the northern portion of the Plateau. It is intended to summarize the data collected and to be useful as art aid to investigators in preparation of manuscripts for publication.

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1989 NOAA-NCEI compiled the NOAA-MMS Marine Minerals Geochemical Database from journal articles, technical reports and unpublished sources from other institutions.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