Inverted Echo Sounder Data Processing Report

: The Inverted Echo Sounder (IES) is an instrument that acoustically monitors the depth of the main thermocline from a moored position one meter above the ocean floor. Additionally, the IESs can be equipped to measure both pressure and temperature. The standard steps for processing IES data are documented here. The effect and purpose of each step are discussed followed by a description of how to apply the computer programs that constitute the step. The FORTRAN and MATLAB codes are also supplied.
