Google Earth now includes third coast

When Google Earth 5.0 was released back in February, it included the capability to view the world ocean landscape from beneath the water surface. This capability now extends to the “Third Coast” of the United States, the Great Lakes. Through a cooperative effort with the NOAA Great Lakes Environmental Research Laboratory (GLERL) and the NOAA National Geophysical Data Center, Google Earth now incorporates detailed bathymetry for the five Great Lakes. Users will be able to explore features such as the canyons and shoals in eastern Lake Superior, the Lake Michigan mid-lake reef complex, and the old river channel, now underwater, that once connected Lakes Michigan and Huron at the Straits of Mackinac.

To highlight some of the interesting coastal and subsurface features of the Great Lakes, the NOAA Great Lakes Environmental Research Laboratory has assembled a narrated Google Earth tour, which you can download at Google's LatLong blog.
