Abstract:

The preliminary planning and approach to site 13 were taken from the JOIDES Atlantic Advisory Panel Report and from a previous detailed survey of the site by R/V Vema of the Lamont Geological Observatory. Several CSP profiles crossing the selected site in various directions show an uplifted portion of the sea floor roughly circular in shape of about 10 kilometers in diameter. In contrast to the smooth bottom of the surrounding abyssal plain, the topography of the small rise selected for the site has a small-scale roughness of amplitude of 40 to 80 meters. The work reported here is a biostratigraphic summary of available samples. Only the most important and biostratigraphically significant components of the faunas have been noted. No attempt has been made to give an exhaustive faunal analysis of the samples seen.

The sediment properties and epoch are extracted from: Maxwell, A.E., et al., (1970) 3. Site 13, In: Maxwell, A.E., et al. (eds.), Initial Reports of the Deep Sea Drilling Project, Washington (U.S. Government Print Office), p. 27-70, doi:10.2973/dsdp.proc.3.103.1970; and from: Maxwell, E., Von Herzen, R. P., Andrews, J. E., Boyce, R. E., Millow, E. D., Hsu, K. J., Percival, S. and Saito, T., (1970) 5. Site 15, In: Maxwell, A.E., et al.

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1989 NOAA-NCEI compiled the NOAA-MMS Marine Minerals Geochemical Database from journal articles, technical reports and unpublished sources from other institutions.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