"Our science advisors had told us to expect thicker, older ice on at least part of the route, so it is something of a mystery where that older ice has gone. It’ll be interesting to see what scientists think about this."
A woman and two men pulling sledges nearly 300 miles across the Arctic sea ice in the dead of winter; temperatures between 0 and -50F, 1,500 sea ice thickness measurements. A short trip by polar standards, unless the sea ice thickness measurements are taken into consideration. Although I have hiked around a bit in the snow – gee whiz. What a great trip. But the sea ice thickness measurements are disconcerting.
They found first-year sea ice on almost their entire route. the scientists had told them they would see multi-year ice on at least part of their route.
