Beschreibung:
  • Fixation of carbon dioxide (CO2) into organic tissues in the ocean and its subsequent sinking act as a "biological pump" removing CO2 from the atmosphere and surface waters to the deep sea. Most of this sinking occurs in large, biologically formed aggregates made up of organic matter, organism frustrules and mineral matter. Strong winds bring nutrient-rich sub- surface water to the euphotic zone and increase biological productivity, i.e., CO2 fixation. More importantly, dust particles introduced simulta- neously to the sea surface become incorporated into large aggregates thereby increasing densities of settling particles and, as a consequence, ef- fecting the rapid removal of newly fixed organic matter to the deep ocean. These recent findings have important implications for the carbon cycling in the sea.
