"/>We have had two days drifting slowly to the north with a gentle breeze and clear sky. The colder temperatures have led to the growth of a thick layer of frost on the rigging, keeping us busy with de-icing activities on Sunday afternoon. Today we installed two ultrasonic anemometers on Tara, which measure the direction and speed of the wind in three dimensions. These instruments allow us to observe the turbulence in the lower layers of the atmosphere. On Saturday night and Sunday morning we had the pleasure of a visit by a female polar bear with two cubs. Once again it was Zargrey who gave us early warning of their approach. After passing an inquisitive eye they were quick to move on after realizing there was nothing to eat from us.
