| | Description | | Polo Seamount is located at 2¿ 42.9' S, 175¿ 5.4' W and is part of the Tokelau Seamounts on the Pacific Plate. It is 4229 m high with the top at -1100 m and the ocean bottom at -5329 m. The seamount has a volume of 3225 km3 and is slightly elongated with an azimuth of approximately 133¿. The edges of the seamount are slightly irregular and there is one predominate rift which radiates out to the southwest from the summit. A saddle to the northwest connects Polo to Siapo Seamount. Dredge AVON2-D41 was taken off the south flank of the southwest trending rift. |
