Using environment tracers for investigation of submarin groundwater discharge

The investigation of material transport via submarine groundwater discharge (SGD) is more challenging. In order to determine the groundwater discharge areas into the sea during studies had been implemented and selected the new methodology of using ecological tracers. During marine and land investigations studies had been successfully used the complex of ecological tracers – stable isotopes 18O and 2H, radionuclide Rn and Ra and other parameters. On the territory of Kobulety had been defined the groundwater flow direction and the areas of their submarine discharge. Within the identified areas was defined the intensity of eutrofication – the value of nitrate and phosphate content in groundwaters and in the sea. Also, had been studied their distribution on the surface and intensity of outwash into the sea.
