Dear all,

I'd like to ask you a question. Is there any especialist in trichodesmium erythraeum bloom? I'd like to ask her/him a question regarding algae blooms.

State-of-the-art: this summer, an algae bloom (trichodesmium erythraeum) has occured in the Canary Islands, in the ocean. There is a huge agreement between local scientists and the local governments that one of the causes are seawater warming (due to climate change), calm waters, lack of wind, and the Saharan dust supply into the ocean (with iron and phosphorus). For a long time, the local government has skipped the European legislation on water treatment, dumping blackwaters into the ocean without any treatment for decades. Several groups (residents, some scientists, and some political parties) are pointing at the poor water management as another element to be considered, and the only one that can be managed locally.

Question: is there any scientific support to the latter hypothesis? I mean, can blackwaters be one of the causes of trichodesmium erythraeum bloom? Could you send me the report/paper supporting this information?

Thank you very much
