Find Great Lakes Temperature Information with CoastWatch Great Lakes
surface water temperature information is just a few clicks of a 
mouse away.  It's at the Sea Grant CoastWatch site on the World Wide 

The CoastWatch site shows temperatures in easy-to-understand graphic
images of all the Great Lakes--Superior, Michigan, Huron, Erie and
Ontario.  It captures daily National Oceanic and Atmospheric
Administration satellite transmissions and presents the most current
information in the form of contour lines (called isotherms) on five
lakewide, 16 regional, and 42 port maps.
This information is important to anglers and commercial fishing
operations for predicting where fish are likely to congregate, and to
educators and students for limnology and map studies.

"Minnesota Sea Grant contributed to this regional project because of the 
importance of surface water temperatures to finding fish on Lake
Superior," said Jeff Gunderson, Associate Director for Minnesota Sea
Grant. "It can also be used as a real-time teaching tool for science

Surface temperatures change quickly with changing weather and winds, so 
CoastWatch will save time and fuel for anglers searching for temperature
breaks. The Minnesota shoreline is divided into three sections, or port
maps, that provide enough detail for anglers to locate important
temperature breaks. 

"We'd like to hear what you think of CoastWatch," Gunderson said. "So if
you use the information, give us a call or send an email message. 
Please bear in mind, however, that we can't keep the clouds away that
block satellite data collection."

Note to Editors:  This CoastWatch data would make a perfect weekly
column for anglers  By publishing water temperature information on a
Friday, you can aid weekend Lake Superior anglers in finding fish.
