The sensitivity of minimum oxygen concentrations in a fjord to changes in biotic and abiotic external forcing
We investigated the possible biotic and abiotic causes of the observed long‐term decrease of oxygen minimum concentrations in the deep water of Gullmar Fjord. Physical factors explained about 40% of the decreased minimum oxygen concentrations since the 1950s. The North Atlantic Oscillation and more...
