The sea ice thickness (less than 10cm) is now enough to walk on it. It was first a polar bear, yesterday, who has been testing it for us. Very close in front of us, he started walking quite confident, and then he was crawling when the sea ice became more fragile, until the surface broke up. Then he had to swim, and we even saw him going under water to keep going where he wanted. Great show that we followed from the inside of Vagabond. Ourself, we still use survival suits to walk on young sea ice! Eric
