| The EM Bird is monitored by a video camera. Here you can see it in the top center. |
A successful flight for the sea-ice studies was conducted today over the Beaufort Sea. The EM Bird is an electromagnetic sonde that uses the conductivity of sea water to detect the bottom of the sea ice. The top of the ice is observed with a lidar altimeter, and the difference is the sea-ice thickness. For these surveys, the aircraft flies 65 meters above the ice, at 55 m/s, and the Bird is towed on a 200-ft rope so it is near the ice.
Ich hoffe, ihr habt auch fleissig Robben gezählt und weitergemeldet!
