Studies on thermal structure in the seas around India

Abstract

The thesis entitled Studies on Thermal Structure in the Seas Around India. An attempt is newlinemade in this study to document the observed variability of thermal structure, both on seasonal newlineand short-term scales, in the eastern Arabian Sea and southwestern Bay of Bengal, from the newlinespatial and time series data sets from a reasonably strong data base. The present study has certain limitations. The mean temperatures are based on an uneven distribution of data in space newlineand time. Some of the areas, although having a full annual coverage, do not have adequate data newlinefor some months. Some portions in the area under study are having data gaps. The consistency newlineand the coherence in the internal wave characteristics could not be examined due to nonavailability of adequate data sets. The influence of generating mechanisms; other than winds and tides on the observed internal wave fields could not be ascertained due to lack of data. However, a comprehensive and intensive data collection can overcome these limitations. The deployment of moored buoys with arrays of sensors at different depths at some important locations for about 5 to 10 years can provide intensive and extensive data sets. This strong data base can afford to address the short-term and seasonal variability of thermal field and understand in detail the individual and collective influences of various physical and dynamical mechanisms responsible for such variability.
