dc.description.abstractThis paper examines the recorded sea level and current data in the Indo-Sri Lanka channel from 2010 to 2011. The shallow channel, which includes Palk Bay, Pamban Pass, and the Gulf of Mannar shelf plays a crucial ecological role, hosting diverse coral formations and sensitive flora and fauna. The currents in the channel are notably influenced by changes in local bathymetry, with peak magnitudes of approximately 80 100 cm/s observed at Pamban Pass. The analysis reveals a close connection between the sea level and currents in the channel and the large-scale dynamics of the North Indian Ocean. The implication is that the remote winds from the eastern or western boundary of the Bay of Bengal or even the equator could impact the local circulation in the channel. Furthermore, the presence of an annual cycle indicates a small but significant seasonal exchange of water masses between Palk Bay and the Gulf of Mannar, which are linked to fresher waters of the Bay of Bengal and saltier waters of the Arabian Sea, respectively. The tides in this region are mixed (mainly semidiurnal), with notable differences between sea level and currents. For instance, at Pamban Pass, the M2 component dominates in sea level, while the S2 component prevails in currents. In addition, the Gulf of Mannar functions as a subdued area where the effects of sea level, tidal and residual currents, and waves are less pronounced compared to the adjacent seas. In contrast, Palk Bay stands out as a dynamic and energetic region with strong seasonal and intraseasonal variability.
