  abstract = {{T}he {C}rozet {A}rchipelago, in the {I}ndian sector of the {S}outhern {O}cean, constitutes one of the few physical barriers to the {A}ntarctic {C}ircumpolar {C}urrent. {I}nteraction of the currents with the sediments deposited on the margins of these islands contributes to the supply of chemical elementsincluding iron and other micro-nutrientsto offshore high-nutrient, low-chlorophyll ({HNLC}) waters. {T}his natural fertilization sustains a phytoplankton bloom that was studied in the framework of the {KEOPS}-2 project. {I}n this work, we investigated the time scales of the surface water transport between the {C}rozet {I}sland shelves and the offshore waters, a transport that contributes iron to the phytoplankton bloom. {W}e report shelf-water contact ages determined using geochemical tracers (radium isotopes) and physical data based on in situ drifter data and outputs of a model based on altimetric {L}agrangian surface currents. {T}he apparent ages of surface waters determined using the three independent methods are in relatively good agreement with each other. {O}ur results provide constraints on the time scales of the transport between the shelf and offshore waters near the {C}rozet {I}slands and highlight the key role played by horizontal transport in natural iron fertilization and in defining the extension of the chlorophyll plume in this {HNLC} region of the {S}outhern {O}cean.},
