The expedition ran into more dense ice floes which forced a change to the expedition planning. However, a benefit is that the scientists and students on board had the opportunity to go out on the ice and take some ice cores. They found some of the floes were multiyear ice, which means that sea ice did not melt last summer. The multiyear ice had a thickness of 2.4 meters (7.9 feet).

Wow! Fascinating! How can you tell if the ice is multi year – is it the thickness or some other properties??
