Description
Tau Tau Seamount is located at 6¿ 11.3' S, 173¿ 39.0' W and is part of the Tokelau Seamounts on the Pacific Plate. It is 3592 m high with the top at -1600 m and the ocean bottom at -5192 m. The seamount has a volume of 1665 km3 and is slightly elongated with an azimuth of approximately 154¿. The edges are slightly irregular with rifts radiating out from the center. The summit was not mapped in by SeaBeam. Tau Tau is part of a cluster of volcanoes oriented at 333¿. A saddle connects Tau Tau to Tanoa Seamount to the north and to a unnamed seamount to the south. Dredge AVON2-D47 crosses the end of the southeast trending rift.
