ProMare Time Series in the Barents Sea: Control of Ice-Edge Blooms by Environment Variables.
Phytoplankton associated with the ice edge in the Barents Sea during the spring and summer is one of the most productive areas in the world oceans. These blooms move northward as the ice recedes, creating a belt of production at the marginal ice zone. Given the complexity of the physical environment...
