Lakebed 2030

Lakebed 2030

Today, only 15% of the lakefloor has been mapped at high-density, leaving gaps in our understanding of the Great Lakes.

The Great Lakes have never been mapped in detail. Though many maps of the Great Lakes show the shape and depth of the lake floor, known as bathymetry, they are created using data that is sometimes decades old and low-density.

Modern, high-density data enables an extremely detailed map and is critical for effective management, research, and innovation, particularly under mounting climate change threats and a growing blue economy in the Great Lakes region.

High-density data provides visualization of small objects such as pipelines, cables, shipwrecks, and boulders.

A map that is easy to use and open to everyone

In 2019, a group of researchers, technologists, and others dedicated to creating a complete map launched Lakebed 2030.

Begun as a grassroots regional initiative that harmonizes governmental and non-governmental efforts, Lakebed 2030 is dedicated to bringing together new and existing bathymetric data to create a new map of the Great Lakes that is easy to use and open to everyone.

Building a better map

In support of Lakebed 2030, GLOS is bringing together the region’s high-density bathymetry data to create The Great Map: a continually updated, open web map that will be part of the Seagull platform.
