  • Aragonite saturation states and pH in western Norwegian fjords: Seasonal cycles and controlling factors, 2005-2009 

    Omar, Abdirahman; Skjelvan, Ingunn; Erga, Svein Rune; Olsen, Are (Copernicus Publications, 2016-07-26)
    The uptake of anthropogenic carbon dioxide (CO2) by the ocean leads to a process known as ocean acidification (OA), which lowers the aragonite saturation state (ΩAr) and pH, and this is poorly documented in coastal ...
