Annotated record of the detailed examination of Mn deposits from DSDP Site 111, Leg 12 (Core 111-3, 111A-12)

Orphan Knoll is a pronounced submarine feature at the foot of the continental rise and bounded on its northeast side by the 4000-meter deep abyssal plain of the Labrador Basin. It lies isolated on the ocean floor some 550 kilometers northeast of Newfoundland and 350 kilometers north of Flemish Cape....

Description
Summary:Orphan Knoll is a pronounced submarine feature at the foot of the continental rise and bounded on its northeast side by the 4000-meter deep abyssal plain of the Labrador Basin. It lies isolated on the ocean floor some 550 kilometers northeast of Newfoundland and 350 kilometers north of Flemish Cape. The DSDP drilling site 111 was originally chosen by the Atlantic Advisory Panel on the basis of Charcot's Flexotir continuous seismic profile provided by CNEXO.
