NASA | Lakes On A Glacier

The video discusses the presence of meltwater on glaciers, ranging from shallow lagoons to deep lakes. Glaciologists observe variations in ice and snow, noting the network structure of lakes. The color of the lakes, particularly the blue hue, indicates their depth. The interaction of sunlight with lake water involves absorption, scattering, and reflection, which can be observed by satellites like Landsat. These lakes absorb more solar energy, leading to increased melting and potential impacts on glacier dynamics, such as speeding up ice flow due to water reaching the glacier base.
