dc.description.abstractWe describe here an application of excess 222Rn to estimate submarine groundwater discharge in a series of small embayments of Ubatuba, São Paulo State, Brazil. Excess 222Rn inventories obtained in 11 vertical profiles varied from (3.3±1.1)·103 to (19±5)·103 dpm·m-2. The estimated total fluxes required to support the inventories varied from (0.6±0.2)·103 to (3.4±0.9)·103 dpm·m-2·d-1. Considering these results, the submarine groundwater discharge advective rates necessary to balance the sub-pycnocline fluxes calculated in Ubatuba embayments ranged from 0.06 to 1.9 cm·d-1. During the period of this investigation (from March/03 to May/2004), the highest 222Rn in excess inventories were observed late in the summer season (March). Taking into account all vertical profiles established, the relative variability was 67%. Although, if we consider only the fluxes determined in both Flamengo and Fortaleza embayments, the relative variation was 21%.
