THE FRESHWATER APPLICATION OF A MULTI-FREQUENCY HF RADAR SYSTEM - PART OF THE EPISODIC EVENT: GREAT LAKES EXPERIMENT (EEGLE)
 
Over the past three decades, HF radar has become an increasingly important measurement tool for oceanography and related applications. The utility of this technique for measuring regional coastal ocean currents, waves and wind was recently tested over freshwater as a first stage experiment in the comprehensive EEGLE research project (The Impact of Episodic Events on Nearshore-Offshore Transport in the Great Lakes). The objective of the HF portion of the research program is to obtain real-time measurements of these key air and water variables necessary for observational, modeling and forecasting activities. To this end, a multi-frequency HF radar (MCR) was deployed at two sites along the shore of southern Lake Michigan (near St. Joseph, Michigan) to provide observations of near surface current and current shear, wind direction and wave height over an area of about 2500 sq. km. These observations covered the same time period in early May, 1998 and geographical region where moored current meters and other in-situ instrumentation were placed. Radial current measurements from the HF system are compared with point measurements at several locations. Encouraging results signify the utility of the HF radar for use in freshwater applications with less aerial coverage than over salt water.
