Description 400-407
Mixed Layer Depths (MLD) on the basis of
temperature and density were calculated for the Bay of
Bengal area. Long term archive data from World Ocean Database
(WOD09) were used for calculating MLD in the study area. During the pre monsoon
period the lowest thermal MLD was observed in the mid basin area with a value
of 25 m. But within the monsoon period MLD was gradually increase in all area
up to a layer of 50 m. In the post monsoon period MLD increase in the upper
Northern region and during winter period highest MLD of 95 m was observed. In
this time it creates a high depressed zone in this area. Density oriented Mixed
Layer was found thinner for the whole year. It was observed as 5 m in the upper
Northern part, but southern area MLD change with season to season and MLD show
highest 65m in the winter monsoon and lowest 20 m pre monsoon period. Surface
current flows of the ocean and sea surface temperature (SST) seem to control to
change the MLD with seasonality, which was also discussed for an annual cycle.
