FIGURE 2. Schematic diagram illustrating the seasonal variation of the major oceanographic currents and circulatory features in the northern Indian Ocean and Gulf of Aden region (modified from Klaus & Turner 2004, compiled and adapted from several sources). Black arrows indicate surface currents (0-100 m), dashed arrows indicate subsurface currents (100-400 m depth) when they are in opposition to surface currents. Black shaded areas indicate the area of seasonal cold-water upwelling. Abbreviations: South Equatorial Counter Current (SECC), Somali Current (SC), Southern Gyre (SG), Great Whirl (GW), Socotra Eddy (SE), North Socotra Warm Eddy (NSWE), and North Socotra Cold Eddy (NSCE).
