The significance of seasonal light and temperature interaction for the latitu...
Due to the global rise in temperature, recent studies predict species shifts towards higher latitudes. The temperate kelp Laminaria hyperborea (Phaeophyceae) is an abundant... -
Net community production of Arctic mixed kelp communities in response to warm...
Arctic marine ecosystems are experiencing rapid environmental changes with respect to warming, ice melt, and terrestrial run-off. The effects of these perturbations can act as... -
FjordLight: addendum to PAR data for Arctic fjords
Fjords in the Arctic are key ecosystems and of great importance to both natural systems and human societies. The in situ monitoring of these systems is however quite difficult... -
