Remarks

• CO₂ Flux:Blue/Red areas indicate ocean uptake/release of CO₂ from/into the atmosphere. The unit is 10⁶gC⋅km⁻²⋅year⁻¹.
• pCO₂:Warm/Cold coloring indicates low/high pCO₂ area. The unit is µatm.
• pH:Lower pH values are represented as warmer colors.
• DIC:Warm/Cold coloring indicates high/low Dissolved Inorganic Carbon area. The unit is µmol/kg.
• TA:Warm/Cold coloring indicates high/low Total Alkalinity area. The unit is µmol/kg.
• Gray coloring shows areas outside the region analyzed.
