Researchers from the U.S. Geological Survey and U.S. Army Engineer Research and Development Center will be available on June 3 for in-person interviews and updates on an invasive carp deterrent study that is underway at Mississippi River Lock and Dam 19.  

WHAT:   Scientists, engineers and contractors installed a temporary, experimental underwater Acoustic Deterrent System, or uADS, to study how invasive carp respond to acoustic, or sound, signals. Next week’s media availability is an opportunity to learn about the progress of this state-of-the-art research since the deterrent system was installed in February. The interview session will be followed by a larger, formal event including local and congressional representatives and stakeholders. The full event agenda is available online.


WHERE: Mississippi River Lock and Dam 19 

             525 N. Water St., Keokuk, Iowa (map)          


WHEN: 11:30 a.m. – 12:15 p.m. CDT on Thursday, June 3 


WHO: U.S. Geological Survey scientist Marybeth Brey 

          U.S. Army Engineer Research and Development Center researcher Christa Woodley  


DETAILS: Images and detailed information about the collaborative uADS project are available in an online media kit
