Abstract : A summary of the first year's results in a program of current measuring techniques employing the electromagnetic method is presented. The data was taken on hydrographic survey cruises ranging to 165 miles offshore from Oregon. The measurements in this first phase consist solely of those taken by the method of towed electrodes behind a ship underway (GEK). Subsequent phases will include data from vertically moored arrays and from shallow water moored flow meter emplacements. The emphasis in this data report lies in the first phase development of the electromagnetic method (towed electrodes) into a highly reliable tool for oceanographic research. In line with this accent both theoretical considerations and field testing are mentioned in this report. At this time the theoretical examination is in its embryonic stage, and the considerations included here are ones particularly applicable to the field work undertaken. This work is presented in a format of individual cruise reports. Some conclusions and avenues of future interest follow. (Author)
