Excellent work and well-written article. This research has important implications for prediction of where water hyacinth populations will accumulate, and these locations can be targeted for control.

John has done a great job running with the project over the past couple of years. He presented these results at the Western Society of Weed Science in 2018.

This is among the most important research results from the DRAAWP project. Can you post more remote sensing results as well? Where are the contributions from NASA scientists, who are listed as co-director(s) on the DRAAWP. I can't even find a short report from NASA Ames Research Center work under the Products from previous technical meetings?

We are waiting on an update for the NASA portion of the project. We also feel that the remote sensing component is interesting and important, and we look forward to posting more information.

Very nice field measurements! I'm interested how the GPS 'buoys' were constructed. Can I have a contact to the authors?

Hi Marton,  
The device was a 2 liter Nalgene bottle, which was buoyant when sealed. We placed a collar made by Sportdog ( in the Nalgene bottle. When we wanted to retrieve the bottle, we used to receiver made by Sportdog, also available at, to locate the floating bottle. In addition, we placed a GPS recorder, made by Trackstick ( in the bottle. After the bottle was retrieved, we downloaded the data from the Trackstick to a computer. This data could be displayed graphically, as in the Google Maps images in the blog post, or as a table.
