Moreover, several special questions still remain quite unclear. The present paper therefore intends to closely examine a number of special questions and to provide a summarizing presentation of the whole problem. However, it is obvious that, in several respects, this paper cannot provide a final answer to all these special questions which belong to the most diverse fields of the natural sciences. Nevertheless, it will clearly delineate the problem for future research. (Translated from Swedish by the Translation Bureau (HEB) Multilingual Services Division Department of the Secretary of State of Canada, 1976).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1989 NOAA-NCEI compiled the NOAA-MMS Marine Minerals Geochemical Database from journal articles, technical reports and unpublished sources from other institutions.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.Supplement to: Naumann, Einar (1922): Södra och mellersta Sveriges sjö-och myrmalmer; deras bildningshistoria, utbredning och praktiska betydelse = Über die See- und Sumpferze Süd- und Mittelschwedens; ihre Genesis, Vorkommen und praktische Bedeutung = The formation, distribution, and practical implications of Ferriferous Lake and bog-ore deposits in Southern and Central Sweden.
