ABOUT THE TALK:

Time series of repeat sections occupied by long-endurance Sea gliders from 2013 through 2019, augmented with contemporaneous profiles collected by Argo profiling floats, quantify monsoon-modulated variability in exchanges between the Bay of Bengal and Arabian Sea. Sections extend south from the coast of Sri Lanka along 80° 30' E and east along 8° N. During the northeast (winter) monsoon, freshwater enters the Arabian Sea from the Bay of Bengal in the upper 200 m, contributing to the formation of a fresh, buoyant barrier layer west of the Maldives that amplifies air-sea feedbacks, with strong impacts on monsoon onset. Variability in transports and water mass properties suggest competition between the direct export path, flowing southward and then westward following the Sri Lanka coast, and the more circuitous offshore path that leaves the coast, eventually joining the westward flowing North Monsoon Current to enter the Arabian Sea through a more southerly path. During the Southwest (summer) monsoon, sections reveal strong eastward subsurface transport of Arabian Sea water between the southern tip of Sri Lanka and 2°N. In contrast to recent numerical and surface drifter studies that emphasize a southern pathway, where Arabian Sea water moves eastward within the Equatorial Under Current, this suggest that the direct path around the southern tip of Sri Lanka may play an important role for transporting high-salinity Arabian Sea water into the Bay of Bengal. Winter and summer monsoon transports and water mass properties show significant interannual variability, likely due to variations in local and remote forcing of circulation around Sri Lanka, and to coastal process along southwest India and the Maldives that modulate exported Arabian Sea waters.
