Abstract:
U. S. Fish Commission Steamer " Albatross " was placed at the disposal of Agassiz, Alexander for an expedition to the Eastern part of the Pacific South of the Panama canl. The collections made during this expedition give ample material for extensive monographs on the holothurians, the siliceous sponges, the cephalopods, the jelly-fishes, the pelagic crustaceans, worms, and fishes of the Eastern Pacific, as well as on the bottom deposits and on the radiolarians and dinoflagellates, diatoms, and other protozoans collected by the tow-nets. Part of the bottom deposits were later sent to Murray John in Scotland for detailed analysis. These observations are reported in: Murray, J. and Lee, G. V., 1909. Reports on the scientific results of the expedition of the" Albatross" to the tropical Pacific, 1899-1900: XII. Memoirs of the Museum of Comparative Zoology, Harvard College, 38(1).

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1989 NOAA-NCEI compiled the NOAA-MMS Marine Minerals Geochemical Database from journal articles, technical reports and unpublished sources from other institutions.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