Particularly the Dreissenid Mussels (Zebra and Quagga). In reading the ‘Spectral Signature Cheatsheet in Remote Sensing’, it has given me hope that there is a solution to the problem of detection.

Here in Colorado the state prides itself on being the “head waters” state. Purity of our waters is vital for the entire nation. However, human interaction and natural forces; wildlife and water flow; means that the spread will continue. We are already expending huge sums of resources to prevent human-induced spread.

We are dependent on a very costly and manpower intensive process that samples each waterway and inspects individual vessels. With limited resources we must be able to target. We need to stay ahead of the spread and that can only be done if we can “see” and/or accurately predict new outbreaks. Remote sensing would be a very valuable tool to do just that.

Is there a R&D process that can look into this issue?

I have been laughing all along learning. I have exams in two days and omg, I’ve learnt a lot. Very comprehensive write-up.
