| Bathymetry of Lake Superior |
 |
Bathymetry of Lake Superior has been compiled as a component of a NOAA project to
rescue Great Lakes lake floor geological and geophysical data and make it more accessible
to the public. This project is a cooperative effort between investigators at the NOAA
National Geophysical Data Center's Marine Geology and Geophysics Division (NGDC/MGG),
the NOAA Great Lakes Environmental Research Laboratory (GLERL) and the Canadian Hydrographic
Service(CHS). Bathymetric data have been collected from the Great Lakes in support
of nautical charting for at least 150 years by the US Army Corp. of Engineers (before
1970), the NOAA National Ocean Service (NOS)(after 1970), and the Canadian Hydrographic
Service. No time frame has been set for completing bathymetric contours of Lake Superior,
though a 3 arc-second (~90 meter cell size) grid is available. |
