Great Lakes Acoustic Telemetry Observation System (GLATOS)

GLATOSWeb compiles acoustic telemetry project information and helps users learn more about ongoing acoustic telemetry projects in the Great Lakes. Scientists have been implanting Great Lakes fish with transmitters and, like the GPS on a car, have been tracking fish movement through a network of receivers placed on the bottom of the lakes. The purpose of GLATOS is to help scientists and the public learn more about Great Lakes acoustic telemetry projects and their contribution to research.

The tool allows you to explore projects, search the database and report a tag.


The GLATOSWeb tool was developed in partnership with the Great Lakes Fishery Commission (GLFC) and the US Geological Survey (USGS). The GLFC acquired acoustic telemetry equipment in 2010, and fish tagged for tracking include lake trout, sea lamprey, walleye, and lake sturgeon.
