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1989 NOAA-NCEI compiled the NOAA-MMS Marine Minerals Geochemical Database from journal articles, technical reports and unpublished sources from other institutions.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

VITYAZ5200	-23.9167	91.6667	-4560	Piston corer	VITYAZ5200-1	Surface	Mn nodule	Several	2 cm to 7.5 cm		Foramineferal ooze	The corer brought nodules ranging in size from 2 to 7.5 cm in brown lime sludge. Due to the fact that the nodules on this set are markedly diverse in appearance, two nodules were studied.
VITYAZ5200	-23.9167	91.6667	-4560	Piston corer	VITYAZ5200-1-1	Surface	Mn nodule	1	3.5 cm		Foramineferal ooze	A two-layer nodule with irregular shape. The outer layer is dark brown with a tinge of brown, with gray streaks, not very solid, easy to crumble, its thickness is 15-17 mm. The core is small has a diameter of 15-18 mm.

Black outer layer, solid, easily separated from core (10 mm thick). A yellowish brown Fe oxide inter-layer. A black kernel, very dense, hard to brake (size 20 mm). At center a pale yellow nucleus (size 1-2 mm).

Easily peeled off and crumbles. Yellowish-brown inner layer,softer, crumbles (10 mm thick). At the border with the inner layer an orange iron oxide film is easily peeled off.
