Isotope composition of ground and surface waters of the Lammin-­Suo swamp massif (Leningrad region)

Lammin-­Suo swamp area is a State hydrological reserve, as well as a training ground of the State Hydrological Institute. The isotopic composition of groundwater and surface water has been measured for the first time. Two different types of water have been identified based on results of δ18О and δ2Н values. The microcomponent composition of the water has been analyzed during further research. The resulting values confirm the earlier assumption of the contribution of additional swamp supply source. Moreover, these results indicate the sorbent properties of peat deposits.
Keywords: water isotopes, microcomponent composition of groundwater, water of the Karelian Isthmus, swamp, the origin of swamp waters.
