The dredges and cores described in this report were taken on KK84-04-28 and KK84-08-24 expeditions in June-August 1984 by the Hawaii University (HIG) from, the R/V Kana Keoki. A total of 51 dredges and 2 cores were recovered and are available at The University of Hawaii (HIG) for sampling and study. The dredge sites are all in the vicinity of the Hawaiian Archipelago seamounts. The KK84 cores are here briefly described to identify visually distinct units holding Fe-Mn deposits based on lithology, color, texture, or other characteristic unique to an interval of sediment.

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1989 NOAA-NCEI compiled the NOAA-MMS Marine Minerals Geochemical Database from journal articles, technical reports and unpublished sources from other institutions.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.This dataset represents the digitized Appendix A - pp. 1-61 of Manheim, FT & Lane-Bostwick, CM (1989). As it is indicated in Chapter 3, Archive Collections, the description of the samples has been done by T. H. Ling and F. T. Manheim. The description is also corroborated by the other USGS Report from Friesen, WB (1987).
