“Glacial River Blues”
Glacier-fed rivers are often rich in colorful sediments. Here, photographer Jan Erik Waider shows us Iceland’s glacial rivers flowing primarily in shades of blue. While the wave action and diffraction in these videos is great, the real star is the turbulent mixing where turbid and clearer waters meet. Watch those boundaries, and you’ll see shear from flows moving at different speeds which feeds the ragged, Kelvin-Helmholtz-unstable edge between colors. (Video and image credit: J. Waider; via Laughing Squid)

Today I learned that when water turns cloudy (eg because it's filled with bacteria) that's called #turbidity. And there are standard tools to quantity turbidity.
The simplest approach is to lower a black and white disc until you can't see it anymore. Or equivalently, fill a glass cylinder until you can't see the bottom anymore. These devices cost like $30 and I can't understand why they're so expensive.
A more precise technique is to shine light into the water and measure how much of it gets scattered sideways. These devices cost like $300 and I can kind of understand why.
Anyway, I think I'm going to print out a black and white picture to put below my experiment jars. Then I can measure and adjust the biomass density somewhat more precisely.

Talks on analysis of #Sentinel1 and #Sentinel2 data by Dipak Paudial and Awnesh Singh respectively took me back to university time & the #Geoinformatics studies in #Jena. Really great data sources as reminded today for applications like #DisasterRisk assessment or #water #turbidity modelling.
