    Description: As a result of the participation of R. V. "Meteor" in the International Indian Ocean Expedition during the winter 1964/65 altogether 37 sounding profiles were obtained in the Arabian Sea (plate 2-18). They are showing the topographic peculiarities of the main features of the sea bottom in this northwestern part of the Indian Ocean: Shelves, continental slopes and rises, deep-sea plains and hills, the Mid-Oceanic Ridge, fracture zones and seamounts. A control chart (plate 1) shows the geographical sounding lines. The coordination of the soundings with the bathymetric sketch and the map of physiographic provinces (B. C. HEEZEN and M. THARP) is represented in fig. 1 and 2. All soundings were obtained by the modern ELAC-Narrow Beam sounder which also accurately records very steep slopes of the sea bottom (fig. 3 and 4 ). Two series of sounding prnfiles (fig. 5 and 6) are showing the main topographic differences of shelf and slope between the eastern African and the western Indian continental margin. The descriptive analysis of all the sounding sections carried out by "Meteor" show the following main results: a) discovery of a very steep towering up seamount in the northern Somali basin at φ = 8° 16' N, λ 53° 12' E, which is rising up from a depth of 5000 m to about -2000 m (plate 3), b) registration of numerous steep canyons in the upper part of the eastern African continental slope near the coast of Kenya (plate 6 ), c) complete representation of a characteristic section across the Carlsberg-Ridge inclusively rift mountains and the Rift-Valley (plate 9), d) new characteristic results of sounding profiles across the Alula-Fartak trench showing very steep siopes on its flancs (plate 18).
