This is exactly what scientists do when they use remote sensing. We're using different colored filters where they use different wavelengths of light. As a class observe the different photos of the sun ...

Scientists used remote sensing to detect plastic in rivers. This tech offers faster, cheaper cleanup and protects oceans.

A first-of-its-kind study from researchers at the University of Minnesota Twin Cities shows how remote sensing can help monitor and remove plastic debris from freshwater environments like the ...
