We hadn't seen any polar bear since 20th November. Yesterday around noon the dogs suddenly barked a lot, a polar bear was already very close to the boat, it was hard to see him in the darkness, although there was a nice moonlight... We scared him away, but he came back few moments later, he was even looking bigger, we moved and shout as much as we could and he finally gave up. Today, during oceanographic observations on pack ice, while snowing heavily, we were probably more careful than usual!
