Both a quasi-biennial variability and an overall linearly increasing trend are identified in the Sub-Antarctic Mode Water (SAMW) subduction rate across the Southern Hemisphere ocean, using the Argo data during 2005-2019. The quasi-biennial variability is mainly due to variability of the mixed layer...
