New ice measuring method developed

ANN ARBOR, Mich. (AP) - Federal scientists said they've developed a method of using satellites to take highly accurate measurements of ice cover on the Great Lakes.

Good information about ice is important to shippers, anglers and others who use the lakes during winter.

At times, previously used techniques for analyzing satellite data have produced errors in distinguishing between ice and open water.

The new method fixes that problem and provides more accurate readings of ice characteristics such as whether it's dense or full of bubbles, and whether it has melted and refrozen.

It was developed by Son Nghiem of NASA's Jet Propulsion Laboratory in California and George Leshkevich of NOAA's Great Lakes Environmental Research Laboratory in Ann Arbor
