170904-N-PO203-199 GREENLAND (Sep. 4, 2017) Peter Legnos, left, president, LBI, inc., and Ignatius Rigor, from the University of Washington, replace the parachute cone on an air-deployable expendable ice buoy (AXIB) at Thule Air Force Base in Greenland in preparation for deployment to the high Arctic near the North Pole. The deployment team, led by the Office of Naval Research (ONR), included personnel from the National Ice Center (NIC), Office of the Oceanographer of the Navy, Environment and Climate Change Canada, Danish Royal Navy and University of Washington. The buoys provide real-time weather and oceanographic data to enhance forecasting, and environmental models thereby reducing operational risk for assets in the Arctic. (U.S. Navy photo by John F.
