Present study consists characteristics of
intruded Bay of Bengal Water mass (BBW) in the South Eastern Arabian Sea (SEAS)
during November 2001 – May 2002 by utilizing Simple Ocean Data Assimilation (SODA)
model outputs (Temperature, Salinity and Currents). During November 2001 the
southward flowing East India Coastal Current (EICC) along with Winter Monsoon
Current (WMC) brings BBW to Arabian Sea traversing around Sri Lanka coast
and feeds the poleward flowing West India Coastal Current (WICC). Even though
EICC reversed its direction by January, the WMC along with the WICC transported
the BBW further north into Arabian Sea.
Maximum northward limit of the BBW was 16°N during January-February which is
the peak phase of WICC. When the WICC reversed its direction by March the BBW
started depleting and by May no trace of BBW was seen in SEAS. Thickness of the
water mass were computed for the entire study region and also vertical
integrated volume transport were computed along transects (77.5°E, 8.25°N,
10.25°N, 12.75°N and 15.25°N) perpendicular to the coast. Thickness of the
water mass was found to

vary from 10 to 60 m during the entire
study period. It was shallow during November and March-April while it was deep during
peak phase of WICC (January-February). Maximum volume transport of 0.8 Sv
towards west along 77.5°E was observed during February. During the period of
study total volume transport was seen to be less towards the Northern transects.
