Abstract:
Site 70 is located about 20 miles north of the northern boundary of the Clipperton Fracture Zone near 140° W. It is the northernmost of the N-S line of sites drilled during Leg 8 to investigate the east-west trending accumulation of sediment centered at about 2°N near 140°W. It lies about 500 miles south of Site 42 of Leg 5, the southernmost of a line of sites continuing to the north. The R/V Argo SCAN survey indicated that the area was one of low, broad abyssal hills, 2 to 10 miles in width on E-W profiles, with relatively thick sediment cover.

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1989 NOAA-NCEI compiled the NOAA-MMS Marine Minerals Geochemical Database from journal articles, technical reports and unpublished sources from other institutions.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