Un nouveau capteur sous la banquise

  • La banquise ondule sous la pression des glaciers
  • Mise a l'eau enregistreur salinite temperature

A salinity and temperature recorder was deployed yesterday, in the middle of South Cape Fiord, five meters under the ice. The instrument was launched in a seal hole, it was easier than drilling a hole by ourselves! Measures occur automatically every two and half minutes, the recorder will be recovered just before ice breaking up, in July. In addition, every three days, the instrument is lower at 10m, 15m, 20m, 30m and 50m to measure water salinity and temperature at these useful depths.

Now, at midnight, the sun is going behind the nearby mountain, but is still high above the horizon! We will have to wait until the end of the summer to see a sunset again. With spring conditions (-22°C in the morning, -10°C during the day), the whole family can now go for longer trips, for scientific measurements, or for picnics, most of the time with the dogs.

Our friends cameramen, on board for two more weeks, didn't hesitate to become temporary baby-sitters to allow France and me to go together for two long rides in the surrounding area. A first one in the mountains: what a pleasure to discover our environment from the closest summits (700m)! Another one up to the end of the fjord, at 30km from the boat, with the icemeter: glaciers are tirelessly pushing the pack ice, which is loosing its shape and rolling in a spectacular way, without disturbing the seals, more and more under the sun.
