Climate change and the timing, magnitude, and composition of the phytoplankton spring bloom
Abstract In this article, we show by mesocosm experiments that winter and spring warming will lead to substantial changes in the spring bloom of phytoplankton. The timing of the spring bloom shows only little response to warming as such, while light appears to play a more important role in its initi...
