Field evaluation of an electromagnetic current meter based vertical profiler / by P.F. Hamblin ... [et al.]. : En13-5/86-204E-PDF

"The need to investigate the role played by suspended sediments in the transport and fate of contaminants in lakes has led to the measurement of current in shallow water and in nearshore areas where surface wave influences are crucial to the dynamics of resuspension. The standard mechanical current meters are inappropriate for these high energy zones. A new generation of solid state current meters has been brought on the market to fulfill these needs. This paper concerns a field evaluation of a vertical profiling system constructed from three such devices operating on the electro-magnetic induction principle. The results are not encouraging in our careful field evaluation. We do not recommend further deployment of these meters for this purpose and encourage the development and testing of other devices. This study is relative to contaminated sediments and the Upper Great Lakes and connecting channels studies"--Management perspective.
