Anthropogenic Carbon Transport Variability in the Atlantic Ocean Over Three Decades

The change in anthropogenic CO2 (Canth) the Atlantic Ocean is linked to Meridional Overturning Circulation (AMOC), that redistributes Canth meridionally and depth. We have employed direct biogeochemical measurements hydrographic data from last thirty years, adjusted using inverse models for each decade with both physical constraints. then computed meridional transports vertical between two sections at interphases by advection diffusion. focused on repeated three latitudes – 30°S, 24 55°N, dividing into boxes. divided net transport upper, deep abyssal layers, an upper northward of a southward component layers. time appears be mainly due modifications lower layer AMOC, combination waters, maintain more consistent time. Vertical plays important role North Atlantic, exporting In South newly formed Antarctic Bottom Water exports strong gradient concentration interphase layers results
