Map of the North Atlantic Ocean published on the eve of the CHALLENGER
Expedition in "The ocean, atmosphere, and life...." by the French geographer
Elisee Reclus. This map shows some very large non-existent shoals to the east
of Newfoundland as well a deep extending to the NE which seems imaginative.
The profile is based on the work of Dayman and Berryman in 1856/1857.
