Description Oceanic eddies are characterised by gradients in the sea surface height (SSH) and temperature both at the surface and the subsurface. However, since the Bay of Bengal waters are more stratified, the gradients in SST may not develop though the subsurface temperature sections and the SSH show prominent eddy signatures. In this investigation, TOPEX altimeter derived SSH and the XBT temperature sections along the Madras Andaman coast have been analysed to study the Bay of Bengal eddies. A well defined anticyclonic eddy is located around 13 degrees N and 83 degrees E from the TOPEX observations averaged over 10-19 August 1993. The thermal sections pass through the southern periphery of the eddy with a prominent trough over the eddy region. The crest noticed around 87 degrees E along the XBT track is due to the presence of a cyclonic eddy adjoining the earlier anticyclonic eddy. Due to the synoptic coverage of the altimeter observations, eddy structures are clear from the satellite observations while only troughs or crests are seen in the XBT sections. Besides these, several cyclonic and anticyclonic eddies have also been located from both the insitu and altimeter observations
