Mechanical and operational details of a Neil Brown Instrument Systems internally recording conductivity, temperature, depth (CTD) profiler

Abstract

The purpose of this report is to discuss the use of a Neil Brown Instrument Systems internal recording CTD. The components of the instrument are described along with the advantages and disadvantages of the internal recording system. Calibration of the pressure and temperature sensors in the laboratory and the method used for in situ calibration of the conductivity sensor is described. A step by step description of the use of the CTD/IR at sea is also included.
