How have recent temperature changes affected the efficiency of ocean biological carbon export?
Abstract The ocean's large, microbially mediated reservoirs of carbon are intimately connected with atmospheric CO 2 and climate, yet quantifying the feedbacks between them remains an unresolved challenge. Through an idealized mechanistic model, we consider the impact of documented climate chan...
