Site 75 is located 300 miles southeast of the Marquesas Islands; 400 miles south of Site 74. It is the southernmost of the sites along the N-S line drilled during Leg 8 to investigate the east-west trending accumulation of sediments centered about 2°N near 140°W. This site is a replacement for the site at 31°S originally chosen by the JOIDES Pacific Advisory Panel (PAP Site 27). The original site was not drilled since a preliminary R/V Argo SCAN survey indicated insufficient sediment thickness.
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1989 NOAA-NCEI compiled the NOAA-MMS Marine Minerals Geochemical Database from journal articles, technical reports and unpublished sources from other institutions.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.
