Summary

Abstract:
ABSTRACT: 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. SUPPLEMENTAL INFORMATION: Supplemental information regarding spatial reference. Gridded data is vertically referenced to lake level or sea level as set by user in online tool "Design-a-Grid" advanced options. Work on this data is incomplete. Completion data is unknown. CURRENTNESS REFERENCE: publication date SPATIAL REFERENCE INFORMATION - GEODETIC MODEL Horizontal Datum Name: North American Datum of 1983 Ellipsoid Name: Geodetic Reference System 80 Semi-major Axis: 6378137.000000 Denominator of Flattening Ratio: 298.257222 Purpose: PURPOSE: Scientific Research, Commercial Exploration, Fishing, Policy and Decision-making |
