This is the time of year when small islands of waterhyacinth break loose from their parent mats, seeking new marinas to clog up. The Madsen team is embedding radio dog collars into freefloating mats to track their movements with the currents, tides, and wind.
This study is conducted in cooperation with DRAAWP, the Delta Region Areawide Aquatic Weed Project.
A radio dog collar is sealed into a plastic bottle.
The bottle is secured into a freefloating mat of waterhyacinth.
