Abstract:

During Discovery Cruise 11, April-May 1966, eleven hauls were made on the crest and on the southern facing slope of Palmer Ridge in the Peake Deep area in order to fill out the information gained last year. Limestones were collected ranging in age from lowest Eocene through to Upper Tertiary, and several hauls successfully sampled the basement beneath these, producing weathered basalts, metamorphosed basalts and dolerites. In Peake Deep on the north slope of Palmer Ridge hard Eocene sediments were core sampled near the base of the slope but no cores could be got near the top.

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1989 NOAA-NCEI compiled the NOAA-MMS Marine Minerals Geochemical Database from journal articles, technical reports and unpublished sources from other institutions.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