All hands on deck
The morning started in Simpson Strait with perfect conditions to support multiple missions throughout the day: 9℃, northwest winds of 15 knots, waves under 1 m, and no ice in sight. Hydrographic launches Gannet and Kinglett were sent away immediately after the morning brief to get started on their surveys, and Nunavut archeologists Drs. Douglas Stenton and Robert Park were taken by CCG helicopter to conduct ground surveys in Washington Bay and Terror Bay.
In the interim, the ship operations focused efforts on servicing aids to navigation. Although each buoy anchor weighs three-quarters of a ton, one buoy had been dragged across the seafloor for over two nautical miles from its original position and into uncharted waters by ice floes. To retrieve it, the CHS tasked their vessels to survey the zone so that the Laurier could venture safely into the area.
Following lunch, deck crews inspected, serviced and repaired beacons positioned throughout the area. Even the ship's electrician was involved, replacing and repairing electrical parts to ensure the effective transmission of signals from a Racon radar beacon to ships sailing through the area. Crews will head back out again after supper to complete some additional range work.
The Parks Canada team spent the day preparing the Investigator, and with the new LiDAR data's ability to provide precise measurements between the boat's centre of rotation, the antennae, the motion sensor and the sonar, the team completed the required calibrations of their multibeam system.
