Lars Jakobsson, geodesic expert, is in charge of maritime boundaries at the Swedish Maritime Administration. He told Swedish Radio that the borders could move 500 meters in both directions.
“We are expecting to see the lines move about 500 meters both outwards and inwards,” he said.
The border of Swedish territory is exactly 12 sea miles (about 22 kilometres) from the coastline. Measurements from the archipelagos are taken from the most outer visible rocks sticking up out of the water.
