From the bathy thermographic data, collected during the first 19
cruises of the Andhra University during the period October 1952 to
April 1953 along the east coast of India, thermal fields at surface, 40, 100,
200 and 400 feet levels have been constructed for the three seasons, viz.,
Post-Monsoon, Winter and Summer seasons. The present study is confined
to the coastal region between latitudes 13" N. to 18" N. and longitudes
80" E. to 84" E. In addition to this area, during winter season,
the study has been extended to an area over the Swatch of No Ground
