Hi guys! I’m trying to detect algal bloom using Landsat images in Aral Lake… do you have any ideas on how to do it? Thank you !!!
Check out these papers for a few ideas:

The most difficult aspect is that algal blooms can be seen by Chl-a in Landsat, but not by their Phycocyanin, as Landsat does not directly observe the wavelength at which they have an absorption feature.
Best of luck!
