Ocean current monitoring via cross-correlation technique and node synchronisation

Abstract

In the North Atlantic Ocean accurate prediction of the trajectory of icebergs would enable optimization of shipping routes and offshore production processes. In this paper, we investigate the practical aspects of the proposed current measurement technique which is based on transit time method and cross correlation signal processing in a flow tank. The experiments are carried out as a prototype of a larger network of acoustic transducers to investigate the feasibility and/or limitations of this system for measuring the average-shallow depth current in the ocean.
