TL;DR: Global ocean NPP changes detected from space over the past decade are described, dominated by an initial increase in NPP of 1,930 teragrams of carbon a year, followed by a prolonged decrease averaging 190 Tg C yr-1.

TL;DR: In this paper, the authors evaluate the physiological underpinnings of global variations in satellite-based phytoplankton chlorophyll fluorescence and find that the three dominant factors influencing fluorescence distributions are chilophyll concentration, pigment packaging effects on light absorption, and light-dependent energy-quenching processes.

TL;DR: The authors compare satellite ocean color-based models (SatPPMs) and those generated from biogeochemical ocean general circulation models (BOGCMs) to a tropical Pacific primary productivity (PP) database consisting of ∼ 1000 14C measurements spanning more than a decade (1983-1996).

TL;DR: In this article, satellite measurements of chlorophyll are used to infer phytoplankton biomass changes and the relationship to sea surface temperature, and they show that the photoacclimation response is an important component of temporal chlorophyLL variability across the global ocean.

TL;DR: In this article, the authors use space-borne lidar observations to overcome the limitations of historical passive sensors and report a decade of uninterrupted polar phytoplankton biomass cycles.
