Ocean acidification and warming seawater temperatures could diminish phytoplankton’s role as carbon sink

14 Oct 2011: Ocean Changes Could Diminish Phytoplankton’s Role as Carbon Sink Warming seawater temperatures and ocean acidification could diminish the capacity of a critical species of phytoplankton to pull carbon dioxide from the atmosphere and store it in the deep ocean , the world’s biggest carbon sink, according to a new study. Under typical conditions, the phytoplankton Emiliania huxleyi develops plates of calcified armor called coccoliths while floating in the ocean’s upper layers before eventually sinking, a process responsible for about 80 percent of inorganic carbons trapped at the bottom of the sea. In a study published in the journal Global Change Biology , researchers at San Francisco State University found that exposure to higher levels of carbon dioxide, which makes seawater more acidic, and higher ammonium levels altered the phytoplankton’s biology and growt...
