Great Lakes Observing System Constructing Technology Demonstrator

The Great Lakes Observing System is developing technology that will support the Lakebed 2030 and the Great Lakes Bottom Mapping Working Group for the collection, processing, archival, discovery, and access of high resolution bathymetric data and related information.  As a precursor, GLOS is developing a prototype to demonstrate the potential of having comprehensive bathymetry, metadata, surfaces, and an inventory of available data. 

The prototype is code named “Catfish” and will be used to educate and inform a broad swath of technologists, policy makers, legislators, researchers, and the general public on the importance of comprehensive mapping of the Great Lakes basin. 

But they can’t do it alone. To complete this project more bathymetric data is needed.

Three questions:

  1. Do you have any available high-resolution bathymetry or bathymetry derived products (i.e., sidescan sonar, backscatter, substrate information, etc.) that you would consider sharing with GLOS in support of this demonstrator?  
  2. If you do not, are you aware of regional groups who may and would consider sharing that data with GLOS?
  3. Are you interested in learning more about this exciting project and potentially getting involved? If so, please visit

Please contact Linden, Data Coordinator, at with any questions or information you may have.
