In April 2009, Google added the capability to view the Great Lakes from beneath the water surface. The Great Lakes Environmental Research Laboratory (GLERL) has developed a basic narrated Great Lakes tour that highlights points of interest in each of the five Great Lakes and identifies a few unique underwater features. The original Great Lakes bathymetric data were compiled by a NOAA (NESDIS-NGDC and OAR-GLERL) and Canadian Hydrographic Service team from archival U.S. and Canadian soundings spanning more than 75 years. Dr. David Schwab (GLERL) generated a dataset of lake depths at points on a grid where the grid spacing is 3 arc seconds (3/60 of a degree, roughly 80 m) and provided it to Google. The Great Lakes are shallow compared to the oceans, the Great Lakes bathymetry will not appear as dramatic to the experienced Google Ocean users. Our intent with this first tour is to inspire others to use this tool to create tours of their own. First you will need to download Google Earth. Once in Google Earth, click the + symbol next to the menu item that reads "Great Lakes KML Tour" and then from the submenu click on the item that reads "Narrated Tour". In some browsers the tour will start automatically. If not, set your browser preferences to use Google Earth rather than download the file. Launch Google Earth Great Lakes Tour |
