Feb 06, 2020 · A study published in Nature Geoscience (Bronselaer et al., 2020) analyzed new observations from autonomous floats with ocean-biogeochemical sensors (Bio-Argo) along with historical shipboard ocean measurements to document changes in Southern Ocean physical and ocean-biogeochemical variables (i.e., temperature, salinity, pH, concentrations of nitrate, dissolved inorganic carbon and oxygen) during the last two decades. Due to the poleward shift and strengthening of the Southern Hemisphere (SH) Westerlies (as a result of increasing GHGs and its impact on the SH polar vortex) during the recent decades, the warm and salty Circumpolar Deep Water (CDW) has intruded deeper into the ...
