Abstract:
Examination of the surface of freshly collected ferromanganese nodules by scanning electron microscopy revealed the presence of microcolonies of rod- and coccus-shaped bacteria which appeared to be anchored to the nodule surface by slime. The attachment of microcolonies by slime to the surface of freshly collected nodules argues against their being contaminants introduced during nodule collection or processing. These results corroborate cultural and biochemical detection of bacteria on ferromanganese nodules.

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1989 NOAA-NCEI compiled the NOAA-MMS Marine Minerals Geochemical Database from journal articles, technical reports and unpublished sources from other institutions.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