New primary production and nitrification in the western subtropical North Atlantic: A modeling study
International audience The original definition of new primary production rests on the assumption that nitrogenous substrate taken up to fuel algal growth is coming into contact with phytoplankton for the first time that year. Therefore, should the generation of nitrate from ammonium by nitrification...
