Whilst the low-salinity karstic groundwater significantly affects the salinity budget of the lagoon, it
CJC 1293 contributes only a small fraction of 7–18% of total radon input to La Palme lagoon. This is partially a result of the comparatively low endmember radon concentration of 1600 ± 200 Bq m− 3, which together with its salinity of 7.3 (Table 1) indicates a mixing of fresh groundwater with seawater in the aquifer, consistent with previous studies of the local karst geochemistry (e.g. Aquilina et al., 2002 and Fleury et al., 2007).

Cretaceous Period drains a wetland and a captured spring (‘lavoir’), supplied by karstic groundwater in the northern section of the lagoon. The temperature distribution indicates only a small spatial influence of discharge on surface temperature in the order of 100 m range, at a water depth of less than 0.3 m. Figure options
