A Towed CTD Chain for Two-Dimensional High Resolution Hydrography

Abstract

The need for accurate two-dimensional datasets of temperature and salinity in the upper ocean led to the development of a new type of towed chain. Low-cost sensors are moulded in fins and may be randomly placed on the tow cable, to which they are inductively coupled for power supply and communications with the deck unit. Construction and operation of the chain are described, and examples of measurements in the Norwegian and Greenland Seas are given.
