At last – time for archipelago nature. Travelling in boat at night among the islets. The boat passes slowly over the shallow areas. Black guillemots swarm like big insects, velvet scoters like heavy black projectiles, arctic terns and black-backed gulls hover over the boat. All islets are different individuals. The sun goes down over Grossgrundet. The night is surprisingly warm and never gets dark. Still, we can see flickering of the lighthouses – white light of Holmögadd, and green of Stora Fjäderägg. For how long will they still send their beams over the straits of Kvarken, in this era of satellite-directed navigation?
