  abstract = {{T}he mean vertical structure of mesoscale eddies in the {P}eru-{C}hile {C}urrent {S}ystem is investigated by combining the historical records of {A}rgo float profiles and satellite altimetry data. {A} composite average of 420 (526) profiles acquired by {A}rgo floats that surfaced into cyclonic (anticyclonic) mesoscale eddies allowed constructing the mean three-dimensional eddy structure of the eastern {S}outh {P}acific {O}cean. {K}ey differences in their thermohaline vertical structure were revealed. {T}he core of cyclonic eddies ({CE}s) is centered at similar to 150 m depth within the 25.2-26.0 kg m(-3) potential density layer corresponding to the thermocline. {I}n contrast, the core of the anticyclonic eddies ({AE}s) is located below the thermocline at similar to 400 m depth impacting the 26.0-26.8 kg m(-3) density layer. {T}his difference was attributed to the mechanisms involved in the eddy formation. {W}hile intrathermocline {CE}s would be formed by instabilities of the surface equatorward coastal currents, the subthermocline {AE}s are likely to be shed by the subsurface poleward {P}eru-{C}hile {U}ndercurrent. {I}n the eddy core, maximum temperature and salinity anomalies are of +/-1 degrees {C} and +/-0.1, with positive (negative) values for {AE}s ({CE}s). {T}his study also provides new insight into the potential impact of mesoscale eddies for the cross-shore transport of heat and salt in the eastern {S}outh {P}acific. {C}onsidering only the fraction of the water column associated with the fluid trapped within the eddies, each {CE} and {AE} has a typical volume anomaly flux of similar to 0.1 {S}v and yields to a heat and salt transport anomaly of +/-1-3 x 10(11) {W} and similar to 3-8 x 10(3) kg s(-1), respectively.},
