Campagne Seamewe 2: Reconnaissance de trace de cable sous-marin dans l'Ocean Indien

Cruise Seamewe 2 has been devoted to the survey of the projected track of a telecommunication cable on a distance of 2300 miles between Djibouti and Colombo. Supplementary data relevant to Djibouti approaches (side scan survey) and the areas were obtained during Leg 1 of Seamewe. The survey involves the seabeam for bathymetry and a mud penetrator 3.5 KHz with a correlator for determination of the acoustic character of the sea floor. Magnetism and gravimetry have been also recorded on most of the surveyed tracks. The near-bottom water temperature had also to be checked in a number of stations
