A Description and Discussion of FREDDEX Oceanographic Measurements
Abstract
During the time interval March June 1979 an experiment called FREDDEX (Front and Eddy Experiment) was conducted in the Atlantic Ocean, north of Bermuda, as a cooperative effort between several organizations and involved measurements made from satellite, aircraft, and three ships. The purpose of FREDDEX was to conduct extensive measurements on the oceanographic characteristics of an ocean eddy and the influence this feature has on long range underwater acoustic transmission. This report discusses various salient aspects of the oceanographic measurements. Results are given for horizontal and vertical temperature structure of the eddy as well as evidence for the rotation of the basic temperature anomaly associated with the eddy. A novel technique is described of utilizing the ensemble of measurements in order to extend the data to the ocean bottom, thereby achieving a complete description of the sound speed profile in the vertical.
