Deep-water renewal in Lake Baikal (Siberia), the world's deepest lake and largest lake by volume, is relatively fast. Water age calculated from tritium and helium as well as from chlorofluorocarbons does not exceed 19 yr. Relative saturation of dissolved oxygen typically exceeds 80%. The equation of state of Baikal water was determined including the(More)
The 3H-3He age of a water mass is a measure of the time that has passed since the water mass was last in contact with the afinosphere. Between 1992 and 1995 a detailed study of3H-3He ages was conducted in Lake BaikaI, the deepest and largest lake by volume on Earth, to investigate deep water renewal in its three major basins. Maximum 3H-3He ages are 14-17(More)
We investigated upwelling events in the pelagic area of Lake Baikal that developed during summer stratification (July–November) using a combination of in situ and satellite observations. These upwellings appear in the centres of local cyclonic macrovortices with compensatory downwelling located on their periphery in coastal areas. The average duration of(More)
