  • Changed value of field methodDescrioption to **BaySys Winter 2017 Solara Communications Ice Beacon protocol ** To measure sea ice drift 14 ice beacons built by Solara Communications and David Babb. The beacons are enclosed within a 20” long tube comprised of 6” internal diameter Drain Water Ventilation PVC (DWV-PVC) with a sealed cap at the bottom end and a waterproof screw on cap at the upper end. An internal frame comprised of acrylic rods and PVC sheets houses the batteries and iridium/GPS unit. The beacon is deployed into a 10-12” deep 8” auger hole that anchors the beacon in the ice and keeps the batteries partially insulated from extreme air temperatures. **Amundsen Leg 1 Ice Beacon Solara Communications Ice Beacon protocol** To measure sea ice drift 10 ice beacons built by Solara Communications and David Babb were deployed on large ice floes in central and southern Hudson Bay. Ice Beacons are contained within sealed PVC tubes (13 cm diameter x 50 cm length) that house a small processor, GPS and Iridium antennae, and a battery pack. The ice beacons transmit their location until the ice floe breaks up and they sink. in BaySys Ice Beacon Data- Churchill River (2017) and Hudson Bay (2018)
