Summary

During the SEAPSO (Leg V) transit cruise of R/V Jean Charcot in the Austral archipelago, we conducted a SEABEAM survey on three unsurveyed seamounts previously precisely located with a new method of SEASAT data analysis. The location site of Fabert Bank was also surveyed and we confirm that, as predicted, no bathymetric feature exists there. The three seamounts were found in the predicted locations and this cruise confirms the 15 km accuracy on the predicted seamounts location. Poorer results have been obtained relating to the predicted heights since it appears that the observed heights of the submarine volcanoes are larger than the predicted ones while the volumes are smaller. This survey confirms also the predictions made concerning the morphological regularity of the seamounts.
