Bathymetry of Lake Superior

small icon of outline of Lake Superior.



A draft version of the Lake Superior Bathymetry was 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. 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.

GEODAS Desktop Software can be used to view, revise, subset and re-format GRD98, ARC ASCII and Binary grids.
