Seasonal variation in total organic carbon in the northeast Atlantic in 2000-2001
International audience Total organic carbon (TOC) was measured in the midlatitudes of the northeast Atlantic in 2000-2001 during the Programme Océan Multidisciplinaire Méso Echelle (POMME). In spring, mixed layer depth (MLD) was positively correlated with the north latitude, while the surface TOC an...
