SAHFOS - Dramatic changes in the biology of the North Atlantic and North Sea | In Deep Water |

"... more unexpected was the discovery that the plankton shift is also strongly driven by an increase in the windiness in the North Atlantic region over the last 50 years. This increase in windiness is something that is often overlooked. In the ocean, windiness promotes vertical mixing of the water, which in turn has profound impacts on surface nutrients levels and the vertical distribution of plankton. In general, windier conditions seem to favour diatoms over dinoflagellates.

The new patterns show major shifts in the distribution of economically important species known to cause harmful effects through toxin poisoning. The wider implication of this discovery are not fully known, but the switch from dinoflagellates to diatoms is likely to have propagated up the food chain to impact much larger animals such as fish and whales."
