NOAA National Geophysical Data Center | Great Lakes Digitization Project

Project Summary

The objective of this project was to produce high-resolution mapping (bathymetry) of lake bottom region. This project is significant because new bathymetry is needed for environmental decision-making in the heavily populated and industrialized Great Lakes region; for modeling of water circulation and various climate change scenarios; and as a base map for scientifically and environmentally related fieldwork. New bathymetry also builds upon the wealth of geological knowledge from the lands surrounding Lake Michigan and becomes, at once, an important contribution to the geologic study of the region.
