Vertical mixing and global change

Vertical mixing produced by wind conditions the responses of phytoplankton.

Patagonian coastal area. Phytoplankton communities will be affected not only by global change, but also by vertical mixing.

We studied the effects of vertical mixing, produced for example by wind, on phytoplankton communities of the Chubut River estuary (marine and riverine) We found that marine communities are more vulnerable than river ones under conditions of vertical mixing, when exposed to a future scenario of higher amounts of nutrients and acidification. This will have important consequences for the trophodynamics of the coastal ecosystems of the Patagonian region.
