Abstract
Recently, there have been increasing doubts of the existence of a seamount “Novara Knoll”, between Kerguelen and Amsterdam Islands, because any hydrodynamical signature in favor of such a topographic releif has never been revealed from our previous analysis of satellite-tracking buoy data as well as historical hydrographic data. Checking of satellite-driven geopotential anomaly and historical bathymetric charts for the area did not show anything more. A precise bathymetric survey over the feature made in April 1991 on board the Marion Dufresne confirmed definitively the non-existence of “Novara Knoll”.
