As part of the International Arctic Buoy Program (IABP), placement of buoys on the Arctic ice cap is among the activities. A variety of buoys are placed by the IABP via various means, in an effort to monitor environmental conditions (wind, temperature, pressure, salinity, etc., depending on the buoy and location) and to track the movement of ice. ICE-PPR coordinates the airlift resources of the US, Canada, and Denmark, to place buoys on the ice or in leads, which is far from land in most cases. There are no land- based or maritime- based operations being contemplated at this time to deliver buoys to their destinations. Buoys will only be delivered by air. A C-130 aircraft operating out of Resolute, as arranged by the RCAF or other air force through established military protocols, will be the primary air operation. Buoys will be dropped in the far north, north of Ellesmere Island. Should it be required, any remaining buoys which were not dropped by the C-130, may be dropped by CC-138 Twin Otter. At this point in time, buoys replacement activity is being only contemplated for only three ice tracker buoys intended to be placed on ice locations following this year’s operation (Op NA-NU 20), in March of 2020.
