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1989 NOAA-NCEI compiled the NOAA-MMS Marine Minerals Geochemical Database from journal articles, technical reports and unpublished sources from other institutions.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

1 Event	2 ID	4 Position	5 Deposit type	6 Quantity	7 Size	8 Substrate	9 Sediment	10 Comment	11 Description
V22-6RD	V22-6RD-1	Surface	Mn coating	Several		Coral			Dredge consisted of branching coral coated on upper surface by polished Mn crust. Lower side of coral was slightly altered.
KA9-12	KA9-12-1	Surface	Mn crust	Several	0.5-0.1.5 cm	Consolidated sediment	Ooze	Highly altered foraminifera ooze	Dredge haul consisted of highly altered foraminifera ooze with a 5 to 15-mm thick Mn crust. The Mn was layered and hummocky on the surface. A few fragments of obsidian and olivine basalt were also present.
KA9-13	KA9-13-1	Surface	Mn coating	Several		Consolidated sediment	Ooze	Highly altered foraminifera ooze	Dredge consisted of highly altered foraminifera ooze and fragments of extrusive rocks. Most of the material was Mn-encrusted.
KA9-21	KA9-21-1	Surface	Mn crust	Several	1.0-2.0 cm	Consolidated sediment	Ooze	Slightly altered foraminifera ooze	Dredge haul consisted of slightly altered foraminifera ooze with a 10 to 20-mm thick Mn crust occurring in numerous layers sometimes separated by a film of clay.
RC14-4RD	RC14-4RD-2	Surface	Mn crust	Several	0.8 cm	Consolidated sediment	Clay		Mn crust on semicompacted clay
KA9-11	KA9-11-1	Surface	Mn crust	Several	3.0 cm thick	Consolidated sediment			Mn crust up to 3.0 cm on highly altered substrates. Samples available at the Smithsonian Museum of Natural History.
