  abstract = {{L}ow-frequency variability of spiciness is observed in the {S}ubtropical {S}outh {A}tlantic over the period 2002-2013 with the {A}rgo gridded product {I}n {S}itu {A}nalysis {S}ystem. {W}ithin the pycnocline, spiciness anomalies propagate at a mean speed of 0.04 +/- 0.02 m s(-1), the same speed as the gyre mean circulation, from the {A}gulhas {R}etroflection region off {S}outh {A}frica (similar to 35 degrees {S}-20 degrees {E}) toward the {S}outh {A}merican coast (similar to 18 degrees {S}-35 degrees {W}). {A}fter 2010, propagation is still found, but stationary local spiciness generation is also found over the {S}ubtropical {S}outh {A}tlantic. {T}his spiciness increase is associated with high values of vertical {T}urner angle below the mixed layer base during late winter. {T}his suggests spice injection resulting from penetrative convective mixing due to air-sea buoyancy loss. {T}hese features may have an impact on the low-frequency warm and salty signal produced by the {A}gulhas leakage in {S}ubtropical {S}outh {A}tlantic and the upper branch of the {A}tlantic {M}eridional {O}verturning {C}irculation.},
