Base map and data from OpenStreetMap and OpenStreetMap Foundation

A series of focused field programs took place within Hudson Bay during 2017 to provide a time series of winter and summer observations from the Bay. The first of these field programs was a winter survey of the Churchill River estuary and mobile ice pack offshore from Cape Churchill in Southwestern Hudson Bay. In summer 2018, 10 ice beacons were also deployed to track the movement of the ice pack and gain insight into the double gyre current movement in this area of the bay.

Method Summary

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.

Method Summary The ice beacons simply transmit their GPS location every hour to an online data portal, allowing us to track the drift of individual ice floes and the relative drift of ice beacons deployed in pairs or in arrays. Live data can be accessed through the Solara online data portal where the transmission frequency can also be adjusted. || For the Amundsen Leg 1 Ice Beacon Iridium Communications Network protocol, once the units are activated they transmit their GPS location at user defined intervals (typically 1 hour) to an online web portal.
