- Аннотация: This study provides first estimates of the water transport timescale for five lakes located in the Larsemann Hills oasis (69◦23′ S, 76◦20′ E) in East Antarctica. We esti- mated lake retention time (LRT) as a ratio of lake volume to the inflow and outflow terms of a lake water balance equa- tion. The LRT was evaluated for lakes of epiglacial and land- locked types, and it was assumed that these lakes are mo- nomictic, with water exchange occurring during the warm season only. We used hydrological observations collected in four seasonal field campaigns to evaluate the LRT. For the epiglacial lakes Progress and Nella/Scandrett, the LRT was estimated at 12–13 and 4–5 years, respectively. For the land- locked lakes Stepped, Sarah Tarn and Reid, our results show a great difference in the LRT calculated from the outflow and inflow terms of the water balance equation. The LRTs for these lakes vary depending on the methods and errors in- herent to them. We relied on the estimations from the out- flow terms, since they are based on hydrological measure- ments with better quality. Lake Stepped exchanged water within 1.5 years. Sarah Tarn and Lake Reid are endorheic ponds, with water loss mainly through evaporation. Their LRTs were estimated as 21–22 and 8–9 years, respectively. To improve the LRT estimates, special hydrological observa- tions are needed to monitor the lakes and streams during the warm season with a uniform observational programme.
