NEW TECHNIQUES IN BATHYTHERMOGRAPH SYSTEMS.

A bathythermograph is an instrument that registers the temperature at various depths of the sea. Classical methods and techniques used for measuring the prevailing temperatures in the oceans, possess many limitations. They are grossly inadequate to meet the present demands of collection of data accurately and expeditiously. Efforts were therefore directed toward solving the basic problems of conventional methods and consequently new techniques with high reliability and operational simplicity required by the user have been evolved using the concepts of modern electronics. This paper discusses the various avenues of approach that led to the present state-of-the-art in bathythermograph systems and highlights the economic aspects relating to their high speed operation for maximum saving of expensive ship time, lightweight and small size for reasons of logistics, principally that of stowage encountered in ships and low operational costs.
