GPS equipment disposable ice motion beacons constructed and developed by Oceanetics were deployed on different types of sea ice by either small boat or helicopter. Deployment consists of drilling a 6-8 inch deep hole using a 10-inch diameter ice auger, and then placing the beacon in the hole. The top of the beacon should be visible to the entire sky. Hourly GPS data are transmitted using Iridium data burst modems from NAL. The email data (attachments) were received at the University of Manitoba. Ice motion beacons were left on the ice and are assumed to have sunk when data transmission ceased.
