Dr.Yenamandra K. Somayajulu who received his post graduation degree in Meteorology and Oceanography, has been awarded a Ph. D. degree in Physical Oceanography. Currently he is working as a scientist in the National Institute of Oceanography (NIO).

Deep sea Oceanography, Satellite altimetry, Acoustic tomography and Ocean circulation being the main interest of Dr. Somayajulu; he has participated in many experimental works. The Arabian sea has been examined for its suitability for applying Acoustic tomography. As a first step, the space-time change of sound speed field in the Arabian sea resulting from hydrographic variations were analysed and used in model simulations to optimise the acoustic source-receiver configurations before the actual field experiment. Numerical experiments to retrieve Oceanographic information through the application of Mathematical inverse methods were also performed. the results of these model simulations were validated through an Acoustic transmission experiment conducted during 1993.

ERS-1 and TOPEX/POSEIDON altimeter data for the South Indian ocean was used to study the seasonal and interannual variability of the regin based on the changes in the eddy kinetic energy fields in 1993 and 1994 and between the two monsoonal regimes. An interesting study of Rossby wave propagation was, undertaken comparing the wave speed obtained from altimetry with a revised theory.

Dr. Somayajulu is an awardee of Indo-British Technical Co-operation Fellowship offered at the University of East Anglia, Norwich , UK during February-Deceber,1996. This training was on the application of Satellite altimeter data to Physical Oceanographic problems. He has also received 2 months training (during1990) at the Woods Hole Oceanographic Institution, USA on the model simulations and analysis of acoustic tomography studies.
