• Overturning maximum is 15.64 ± 1.39 Sv; Meridional heat and freshwater transport are 0.27 ± 0.10 PW and 0.23 ± 0.02 Sv, respectively.

• Excluding the mesoscale eddies from the section increased the meridional heat transport by 0.12 PW.

• The distribution of water masses and currents reflects the favorable position of the section for observing.

• This assessment of Southern Ocean biogeochemistry has assimilated existing knowledge and presented new data that show the integral role of biogeochemical cycling – of iron, carbon and major nutrients in particular – in supporting marine ecosystem functioning and regulating sea-air CO2 fluxes at regional and global scales.

•  The response of regional phytoplankton communities is expected to differ at short- and long-term, an overall trend toward smaller flagellates is expected.

•  Five main research gaps in the current understanding on phytoplankton response to climate change in the NAP are identified.

• Achieving these goals will only be possible with the inter-collaboration of Antarctic research programs and scientific community under a common research framework.

• The SACW is composed by four STMW varieties and is the dominant water in the tropical Atlantic.

• ∼34% of Subtropical Indian Mode Water (STIMW) contributes to the mixing fraction of the South Atlantic Central Water.

• An averaged STIMW volume transport of 5.5 ± 3.2 Sv is estimated between 1993 and 2017 towards the South Atlantic.

• ∼20% of STIMW reaches the North Brazil Current through the southern South Equatorial Current bifurcation.

• Cyclonic and anticyclonic eddies transport similar mixing fractions of mode water varieties.

• The low grazing indices and the high diatom biomass observed in the NAP suggest that the diatom bloom was in a fast sinking process.

• Observations corroborate the concept that highly productive Antarctic coastal marine ecosystems are effective biological carbon pump systems.

• This scenario represents a low energy input from the primary producers to the classic short diatom–krill–whale Antarctic food chain.

• The spatial variability of the carbonate system parameters is clearly greater in spring and summer than in autumn and winter.

• The carbonate system parameters on the surface of the strait follow seasonal FCO2 dynamics, that is, sea ice dynamics.

• The effects of intensified summer CO2 uptake on calcite and aragonite saturation in surface waters may emerge in the coming years.

• CO2 fluxes vary from small outgassing to strong sink conditions.

• Enhanced CO2 uptake on the western domain was associated with salinity variations.

• Increased haptophyte concentrations boosted the CO2 uptake in the gyre.

• Intense CO2 uptake in the eastern domain (30°S) was associated with haptophytes.

• We analysed the CO2 system in an important region of the Southern Ocean.

• The Gerlache Strait acts as a stronger CO2 sink than nearby open ocean areas during the austral summer.

• We identified both strong and near-equilibrium sink scenarios for FCO2 from 1999 to 2017.

• The pattern of variability of FCO2 has changed since 2012 to a higher frequency of years with a strong CO2 sink.

• Carbonate system has been driven by dilution/evaporation and sea–air CO2 exchanges.

• The Patagonian shelf is a key area of anthropogenic carbon uptake.

• SACW is acidifying faster in the Patagonian shelf-break than in the South Atlantic.

• AAIW is under risk for aragonite undersaturation near the Patagonian shelf-break.
