ABSTRACT :

The major currents along the Eastern Africa consist of the Somali Current, South Equatorial Counter Current and the reverse one, the Somali Current and the East Africa Equatorial Current. These surface currents exhibit a marked degree of seasonality with significant impacts on the regions productivity and climate. It has been reported that there have been few measurements of these oceanic systems in the region. During the lifespan of the IOC-UNESCO sponsored project of ODINAFRICA large quantities of data has been identified and processed from open source data archives both from satellite remote sensing as well as in-situ observations and ocean buoys a number of which is now available online through the African Coastal and Marine Atlas (ACMA) web portal. In this study some of these data have been used to analyze climatology of the Indian Ocean, anomalies and identification of stationery eddies in the Somali Current. Timing the seasonality of these major currents are also brought into focus with respect to some of the ocean properties, which may be used in synergy with other studies on productivity and climate change.
