This work describes the Dutch participation to the first International Polar Year, 1882-1883. The main objective of the expedition was to take meteorological and other scientific observations and assess the navigability of the Kara sea during the winter. It was undertaken on the steamship Varna along with the Danish Polar Expedition abord the Dymphna.

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1989 NOAA-NCEI compiled the NOAA-MMS Marine Minerals Geochemical Database from journal articles, technical reports and unpublished sources from other institutions.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