  abstract = {{T}he {A}rgo dataset is used to study the winter upper-ocean conditions in the northeastern subtropical ({NEA}) {A}tlantic during 2006-12. {D}uring late winter 2010, the mixed layer depth is abnormally shallow and a negative anomaly of density-compensated salinity, the so-called spiciness, is generated in the permanent pycnocline. {T}his is primarily explained by unusual weak air-sea buoyancy flux during the late winter 2010, in contrast with the five other studied winters. {P}articularly deep mixed layers and strong spiciness anomalies are observed during late winter 2012. {T}he 2010 winter conditions appear to be related to historically low {N}orth {A}tlantic {O}scillation ({NAO}) and high tropical {N}orth {A}tlantic index ({TNA}). {I}nterannual variability of the eastern subtropical mixed layer is further investigated using a simple 1{D} bulk model of mean temperature and salinity linear profiles, based on turbulent kinetic energy conservation in the upper-ocean layer, and forced only with seasonal air-sea buoyancy forcing corresponding to fall-winter 2006-12. {I}t suggests that year-to-year variability of the winter convective mixing driven by atmospheric buoyancy flux is able to generate interannual variability of both late winter mixed layer depth and spiciness in a strongly compensated layer at the base of the mixed layer and in the permanent pycnocline.},
