AB The current glacial retreat in the northern Antarctic Peninsula region is activating the hydrologicalsystem. The study of the dynamics of such system is important considering the impact of water and matterflows on ecosystems. In the case of lakes it is important to know their connection to the surface andunderground flow. Analytical models, as the proposed by Redozubov (1966), predict for large lakes thepresence of taliks with a direct connection to the aquifers below the permafrost, estimating positivetemperatures (1.49ºC) in the talik coldest part. However, hydrochemical analysis (SO42-/Cl- relationships)of one of the deepest lakes in the studied region - Esmeralda Lake in Cape Lamb, Vega Island - and of thegroundwater around it seems indicate that doesn’t exist such connection. This has been confirmedconsidering the temperatures of the water and sediments of the lake, recommending that the predictionsof such analytical model must be checked in the field
