"Telemetry" refers to the wireless transmission of information, often via radio waves, from one location to another. Our public radio-style audio series helps transmit some of Yellowstone's scientific investigations to listeners, wherever they are. Telemetry is supported by Yellowstone Forever and by a generous grant through the Eyes on Yellowstone program, made possible by Canon U.S.A., Inc. Thanks also to the Acoustic Atlas at the Montana State University Library.
