harmonizing the collection, sharing, and use of lake floor data for the great lakes and their connecting channels
The Great Lakes Bottom Mapping Working Group (BMWG) was formed in 2016 to facilitate the collection, harmonization, sharing, and use of continuous high-resolution maps and data about Great Lakes bathymetry, habitat, maritime cultural resources, and biology.
The working group is a collaborative effort to promote communication and collaboration among data providers and data users, facilitate access to data, promote use of technical standards for mapping and habitat classification, and prioritize regional mapping needs.
The working group consists of agencies, organizations and citizens with an interest in some aspect of lake bottom environment. Any individual or organization can participate simply by signing up.

Just Published: “Costs and Approaches for Mapping the Great Lakes”
In 2020, we asked three experienced survey companies “What will it take to map the Great Lakes at high-density?”
Using different strategies and technologies, XOCEAN, Orange Force Marine Ltd., and Fugro reported on technologies that could be used to fill gaps, laid out timelines, and estimated the overall cost.
We discovered that, with today’s emerging scanning technologies, with the proper funding, a high-density map of our lakebed is well within grasp.
Using their findings, we just published our Costs and Approaches for Mapping the Great Lakes report.
