Última Inertial currents in the Indian Ocean derived from satellite tracked surface drifters ArchiMer Saji, P. Kuttan; Shenoi, Satheesh C.; Almeida, Anselm; Rao, Gangadhara. Satellite-tracked surface drifters were used to analyze the characteristics of inertial currents in the tropical Indian Ocean. The drifters were drogued at 15 m depth and had wind-produced slips less than 0.1 % of the wind speed. The rotary spectra of surface velocity components indicated the significance of inertial currents. They are circular (rotary coefficient > 0.5), highly intermittent and contribute up to 46 % to the total kinetic energy of the surface flow field. Events of inertial activity, either triggered by the passage of atmospheric disturbances or by the local fluctuations in the atmospheric pressure (winds), did not last for more than 4 to 5 inertial cycles. The observed inertial frequency exhibited a shift towards the red end of the...

The last global synthesis of the evolution of the Indian ocean which satisfactorily describes the kinematics of the five major plates, up to the initial stages, dates back to Norton and Sclater [1979]. Although the most recent phases of evolution have been largely detailed, in particular in the proximity of the triple junction, the initial stages of evolution have been generally described by models quite speculative and generally only constrained by pairs of plates. The recentmost gravity data based on the altimetric satellites SEASAT, GEOSAT and ERS1 [Sandwell and Smith, 1992] give an homogenoeus image of sea-floor topography. These data, declassified to the south of 30°S, reveal previously unknowkn features of the sea-floor fabric and allow to further...
