🚨New Review!

Characteristics and changes of glacial lakes and outburst floods🧊🌊

This Review highlights that both glacial lakes & glacial lake outburst floods (GLOFs) will increase with ongoing deglaciation

@WaterSHEDLab @sentinel_hub @planet Our recent paper suggests that this lake is potentially dangerous.

📌New Publication-GLOFs from Ranzeria Co in 2013 and Jiweng Co in 2020 in the Tibetan Plateau destroyed local infrastructure and vegetation, and eroded river banks. The study reveals the causes, mechanisms, and flow dynamics of both events. @GuokingZhang

Accounting for subaqueous melting from lake-terminating glaciers increases estimated glacier mass loss across the Himalaya by 7% over the past 20 years, according to a study in @NatureGeosci. 🔒 https://t.co/sqcPMVo9AG

Check out @Nature's research highlight about our recent study showing how the inclusion of subaqueous (i.e., underwater) mass loss from expanding glacial lakes increases estimates of Himalayan glacier mass loss compared to existing estimates https://t.co/tOyNAoZPTa

[ESA Earth Observation @ESA_EO]

Scientists combined satellite & bathymetry data to estimate the volume of water the lakes held.
The most significant underestimation, of 10%, occurred in the central Himalaya, where glacial lake growth has been the most rapid.

How did they found out about this discrepancy?
As Tobias Bolch from @tugraz puts it, satellites "cannot ‘see’ underwater". This had led to a gap in our understanding of the full extent of ice being lost from lake-terminating glaciers.”

[ESA Earth Observation @ESA_EO]

Turns out that we have been underestimating - by 6.5% - ice loss from Himalayan glaciers that terminate in lakes.
And that's because of the 'invisible' subaqueous ice loss!
What is it and why should we care?
