Sous la banquise, l'eau très froide

At least, just before leaving, our colleague Nicolas could enjoy a perfect weather. The ADCP (Acoustic Doppler Current Profiler) was set up under the ice during a complete tide cycle. While it was recording all currents continuously and with high resolution, from the surface to the bottom, we were sending down the CTD (Conductivity Temperature Depth) every thirty minutes. During this 12 hours station on pack ice, few kilometres offshore, a big polar bear passed not far from us, hidden by ice blocks and snowdrifts.
