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1989 NOAA-NCEI compiled the NOAA-MMS Marine Minerals Geochemical Database from journal articles, technical reports and unpublished sources from other institutions.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

| CHA-248 | CHA-248-2-R | 0.000 | 248 | Surface | Mn nodule | 1 | 7.5 cm | Core; pumice | Red clay | Brown-red and yellowish brown when dry, unctuous when wet; coherent; sublustrous streak. | A nodule, 7.5 cm in diameter, with nucleus of much altered pumice surrounded by alternating light and dark bands. Similar to nodules shown by Murray and Renard (36: plate II, fig. 1; plate IX, fig. 4). Only the outer rind was analysed. | M 313 |
| CHA-252 | CHA-252-1-R | 0.000 | 252 | Surface | Mn nodule | 1 | 7.5 cm | Core; pumice | Red clay | Reddish or light brown and grey-brown when dry; plastic and fine grained; breaking up with difficulty in water. | Almost spherical 7.5 cm diameter nodule with of three zones: (i) a yellowish palagonite core; (ii) a dark layer of manganese oxides 0.8 cm thick, (iii) an outer zone with concentric structure with thin bands of clay (?) Only the outer rind was analysed. | M 316 |
| CHA-276 | CHA-276-2-R | 0.000 | 276 | Surface | Mn nodule | 5 | 2.0-3.0 cm | Five small spherical nodules, having diameters ranging from 2-3 cm, closely resembling those shown by Murray and Renard (36: plate IV, figs. 7, 8). All had yellowish altered volcanic core. Only internal was analysed except for HgO2, ThO2 and CeO2 | M 344 |
