This photo raises a question: How far can we go to understand our planet? Scientists walk on drifting sea ice, with the only light coming from the Polarstern vessel and their headlamps. This photo is a part of my recent book “Into the Arctic Ice,” which shows the scientific work and life around the North Pole. Please follow @estherhorvath for more polar science stories.」12月7日 16時40分
