November 28, Ocean acidification stimulates mass development of toxic algae

If carbon dioxide levels continue to increase in the atmosphere and consequently also in the ocean, this could favour the mass increase of toxic algae, with far-reaching consequences for the pelagic food web.

This has been demonstrated by a long-term experiment off the Canary Islands, conducted by an international group of scientists led by the GEOMAR Helmholtz Center for Ocean Research Kiel

Undoubtedly, global warming is the most prominent impact of rising greenhouse gas concentrations in the atmosphere.

But she is not the only one. The higher the carbon dioxide (CO2) content in the atmosphere, the more CO2 the seawater absorbs.

There, the gas triggers chemical reactions that lower the pH. This process, called ocean acidification, affects many creatures in the sea. The consequences for marine ecosystems can be v
