W.H.O.I./Brown conductivity, temperature, and depth microprofiler

Abstract

A Conductivity, Temperature and Depth (CTD) profiler has been designed to make precise fine scale measurements of these physical parameters in the ocean. This CTD system consists of a shipboard Data Terminal deck unit and an underwater unit which provides continuous sampling of the three variables as it is lowered into the water. Additional sensors can be added to measure other variables; the most common is dissolved oxygen. This report is a detailed description of the CTD System and includes the necessary documentation to operate and maintain the equipment.
