The North Atlantic & Arctic

Between Scotland and the Pole lies the kelp forest’s cold frontier: Iceland astride the meeting of warm Atlantic and Arctic water, the Faroes wrapped in some of the strongest tides on Earth, tiny Helgoland holding Germany’s only kelp beds alongside a marine science record more than a century long, and beyond them Greenland and Svalbard — where kelp grows in polar light beneath retreating sea ice, expanding into fjords that glaciers have only just given back. This is where kelp is winning ground, for now, and it deserves watching.
