The world’s strongest tidal current
Saltstraumen is the world’s strongest tidal current and connects the Skjerstadfjord with the open sea. The whirlpools occur as the tide pushes large bodies of water in and out of the narrow channel. The difference in elevation between the outside and the inside of the channel can reach over three feet. It only takes 150 days before the entire fjord is filled with new water in the continuous exchange with the open sea. The massive forces ensure that the entire fjord is always on the move. This way, our salmon can thrive and exercise in clean waters full of oxygen.
