| Great Lakes Bathymetry |
 |
Bathymetry of Lakes Michigan, Erie, Saint Clair, Ontario and Huron 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. Lake Superior bathymetry partially completed. The
present contours and grids have been partially derived and completely compiled here
at NOAA's National Geophysical Data Center (NGDC) using a variety of sources of data
including the NOS Hydrographic data base and the Canadian Hydrographic Service (CHS)
smooth sheets. This project is a cooperative effort between investigators at the NGDC,
the NOAA Great Lakes Environmental Research Laboratory and the Canadian Hydrographic
Service. Bathymetric data used for this project 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 (after 1970), and the
CHS. |
