| Zusammenfassung |
| Modern process studies of the hydrologic balance of Lake El'gygytgyn,
central Chukotka, and the sediment income from the catchment were carried
out during a field campaign in spring and summer 2003. Despite high
uncertainties due to the limited data, the results provide important first
estimates for better understanding the modern and past sedimentation
processes in this basin. Formed ca. 3.6 million years ago as a result of a
meteorite impact, the basin contains one of the longest paleoclimate records
in the terrestrial Arctic. Fluvial activity is concentrated over the short
snowmelt period (about 20 days in second part of June). Underground outflow
plays a very important role in the water balance and predominates over
surface outflow. The residence time of the lake water is estimated to be
about 100 yr. |
