Abstract The Bay of Bengal (BoB) plays a fundamental role in controlling the weather systems that make up South Asian summer monsoon system. In particular, southern BoB has cooler sea surface temperatures (SST) influence ocean–atmosphere interaction and impact monsoon. Compared to southeastern BoB, southwestern is cooler, more saline, receives much less rain, influenced by current (SMC). To examine these features on monsoon, Boundary Layer Experiment (BoBBLE) was jointly undertaken India...
Abstract During the Bay of Bengal (BoB) Boundary Layer Experiment (BoBBLE) in southern BoB, time series microstructure measurements were obtained at 8°N, 89°E from 4 to 14 July 2016. These observations captured events barrier layer (BL) erosion and reformation. Initially, a three-layer structure was observed: fresh surface mixed (ML) thickness 10–20 m; BL below 30–40-m with similar temperature but higher salinity; high salinity core layer, associated Summer Monsoon Current. Each these three...
Abstract The inflow of high-saline water from the Arabian Sea (AS) into Bay Bengal (BoB) and its subsequent mixing with relatively fresh BoB is vital for north Indian Ocean salt budget. During June–September, Summer Monsoon Current carries high-salinity AS to BoB. A time series microstructure hydrographic data collected 4 14 July 2016 in southern (8°N, 89°E) showed presence a subsurface (60–150 m) core. core was composed warm saline overlying cold water. lower part double-diffusive fingering...

The oxygen minimum zone (OMZ) in the Bay of Bengal (BoB) is unique owing to its curious capability maintain steady dissolved (DO) levels. In this study, we identify a process by which levels BoB are sustained above tipping point, using DO and microstructure profiles southern Argo over entire basin. High salinity core (HSC) rich advected Summer Monsoon Current (SMC) into BoB. Vertical mixing driven turbulent salt-fingering processes recharge concentration thermocline OMZ. HSC identified data,...
