A wave of companies are exploring how seaweed can deliver multiple environmental and commercial benefits

Wissenschaftler waren verblüfft, als 2011 im tropischen Atlantik ein Algenband wuchs, das länger war als die gesamte brasilianische Küste – ein Gebiet, in dem es normalerweise keine Nährstoffe gibt, die ein solches Wachstum fördern würden. Eine Gruppe von US-Forschern hat nun einen Hauptverdächtigen ausgemacht: menschliche Abwässer und landwirtschaftliche Abflüsse, die über Flüsse ins Meer gelangen. […]

This poem is inspired by recent research, which has found that excess nitrogen has made sargassum the world’s largest harmful algal bloom. Sargassum is a genus of large brown seaweed (a type of algae) that floats in island-like masses and never attaches to the seafloor. Typically, sargassum blooms exist in low-nutrient waters off the ...

Where does the seaweed come from? "Gulfweed" or "sea holly," as its sometimes called, originates in the Sargasso Sea. Currents push it south, then east, either into the Caribbean Sea, the Gulf Stream or the Gulf of Mexico. The Gulf Stream carries it north, unless stronger east winds drive it onshore. The rest circles the Atlantic until it sinks and dies in the Sargasso Sea. Is there anything good about seaweed? In moderation, it has many environmental benefits, such as holding beach sand...
