LéXPLORE Letters No. 35
This newsletter was generated on the 19-12-2023.
The figures below are showing data for the period 28-11-2023 to 12-12-2023.
Until today, Thetis sampled 4049 depth profiles on Lake Geneva. In this Newsletter we show 26 profiles, so just 0.64% of the recorded data. The complete data set is available at Datalakes.
Data highlights of this issue
Early December observations start where November left off: Rainy, wind and rather cold.
That results in rather cold surface water layers of the lake, with some heat from previous seasons stored below 30 meters depth, where we find positive temperature anomalies up to +1.4 Kelvin. The high frequency of precipitation and snow melt events keeps the salinity levels of the lake extremely low.
With low temperatures and constant shuffling of the water column, we expect biological activity to be low, resulting in low oxygen levels. Unfortunately, faulty oxygen concentration values leave us a bit in the dark about absolute concentration amounts, but relative oxygen abundance is low, as is the norm for this time of the year.
