Experimental demonstration of current mapping using distributed networked underwater sensors

Abstract

This paper proposes a method for ocean current mapping using distributed networked sensors and presents preliminary experimental results by this approach. Conventional acoustic tomography uses the acoustic sensors distributed on the periphery of an area of interest. Environmental reconstruction requires solving a challenging high dimensional inverse problem, typically requiring substantial computational effort. Given distributed sensors, currents can be constructed locally based on data from neighboring sensors. An acoustic communication and networking experiment was conducted near the Sizihwan Bay in Kaohsiung, Taiwan, in May 2011. The collected communication signals are used to demonstrate the proposed method for inverting the currents as a function of space and time. The procedure is simple and can be implemented in real-time using in-buoy processing. General TermsExperimentation

Kalman tracking of ocean current field based on distributed sensor network

“…Recently, a Distributed Networked Underwater Sensors (DNUS) system was proposed to provide oceanographic monitoring over large areas [4]. The low-powered distributed sensors can be easily deployed, and ocean current is constructed locally based on data from neighboring sensors.…”
