A theoretical model of physical and biogeochemical dynamics in the Subarctic Atlantic Ocean, where biological productivity is predicted to decline under future warming scenarios, suggests that the dominant driver of the decline is reduced northward nutrient transport due to slowing of the Atlantic Meridional Overturning Circulation; such theoretical insight might yield improved marine biogeochemistry projections for the next century, according to the authors.
