heal.abstract	In-situ underwater gamma-ray spectrometer KATERINA was used for continuous measurements of radon progenies (214Pb,214Bi), thoron progeny (208Tl) and40K in submarine groundwater discharge (SGD) sites at Kalogria Bay, SW Peloponnesus (Greece). The spectrometer was deployed attached on measuring platform along with two conductivity - temperature data loggers while underwater battery packs supplied the system for acquisition periods up to 25 days. The radionuclide time series together with salinity data were obtained for spring (wet) and summer (dry) seasons. The40K activity concentrations correlated well with salinity of the emanating groundwater. Although the214Bi and208Tl activities showed usually similar trends anticorrelating with salinity, in some cases208Tl did not follow the214Bi record due to changes in the dynamics of the groundwater aquifer. As the half-life of220Rn is very short (55.6 s), its concentration in SGD may depend on the distance from its origin to the monitoring point. The observed temporal variations of214Bi and208Tl confirmed advantages of continuous in-situ monitoring of SGD in coastal areas. © 2011 Elsevier Ltd.	en
