  abstract = {{T}he subterranean flow of water through sand barriers between coastal lagoons and the sea, driven by a positive hydraulic gradient, is a net new pathway for solute transfer to the sea. {O}n the sea side of sand barriers, sea-water circulation in the swash-zone generates a flux of recycled and new solutes. {T}he significance and temporal variability of these vectors to the {F}rench {M}editerranean {S}ea is unknown, despite lagoons constituting ~ 50% of the coastline. {A} one-dimensional 224 {R}aex /223 {R}a reactive-transport model was used to quantify water flow between a coastal lagoon ({L}a {P}alme) and the sea over a 6-month period. {H}orizontal flow between the lagoon and sea decreased from ~ 85 cm d-1 during {M}ay 2017 (0.3 m 3 d-1 m-1 of shoreline) to ~ 20 cm d-1 in {J}uly and was negligible in the summer months thereafter due to a decreasing hydraulic gradient. {S}eawater circulation in the swash-zone varied from 10 to 52 cm d-1 (0.4-2.1 m3 d-1 m-1), driven by short-term changes in the prevailing wind and wave regimes. {B}oth flow paths supply minor dissolved silica fluxes on the order of ~ 3-10 mmol {S}i d-1 m-1. {L}agoon-sea water exchange supplies a net dissolved inorganic carbon ({DIC}) flux (320-1100 mmol {C} d-1 m-1) two orders of magnitude greater than seawater circulation and may impact coastal ocean acidification. {T}he subterranean flow of water through sand barriers represents a significant source of new {DIC}, and potentially other solutes, to the {M}editerranean {S}ea during high lagoon water-level periods and should be considered in seasonal element budgets.},
