7 p, 1.1 MB Gephyrocapsa huxleyi ( Emiliania huxleyi ) as a model system for coccolithophore biology / Wheeler, Glen (The Marine Biological Association of the United Kingdom) ; Sturm, Daniela (School of Ocean and Earth Science University of Southampton Southampton UK) ; Langer, Gerald (Universitat Autònoma de Barcelona. Institut de Ciència i Tecnologia Ambientals)
Coccolithophores are the most abundant calcifying organisms in modern oceans and are important primary producers in many marine ecosystems. Their ability to generate a cellular covering of calcium carbonate plates (coccoliths) plays a major role in marine biogeochemistry and the global carbon cycle. [...]

(Centre de Formation et de Recherche sur les Environnements Méditerranéens) ; Ziveri, Patrizia (Universitat Autònoma de Barcelona. Departament de Biologia Animal, de Biologia Vegetal i d'Ecologia)
Ocean acidification is a result of the uptake of anthropogenic CO₂ from the atmosphere into the ocean and has been identified as a major environmental and economic threat. The release of several thousands of petagrams of carbon over a few hundred years will have an overwhelming effect on surface ocean carbon reservoirs. [...]
