Regulators, decision makers, public affairs officers, industry representatives, and other members of the international regulatory community have a high need for training materials on underwater acoustics as well as instructional resources that can be quickly accessed and viewed. To meet this need, the Discovery of Sound in the Sea (DOSITS) Team will facilitate a free, five-part webinar series for the international regulatory community on topics related to underwater sound. The webinar topics will include basic science concepts related to underwater sound, marine animal sound production/reception, and the potential effects of sound on marine animals. Content will all be derived from peer-reviewed research. Each webinar will last approximately 60 minutes and be comprised of two, 15-20 minute presentations, followed by a period of facilitated discussion. All webinars will be archived on the DOSITS website (the Webinar Series for Regulators of Underwater Sound, http://www.dosits.org/resources/all/decisionmakers/ircwebinar/ <http://www.dosits.org/resources/all/decisionmakers/ircwebinar/>) along with webinar presentations and a listing of related DOSITS website content links. The first webinar of this free, five-part series will be held on Friday, November 13, 2015, at 12:00pm ET. Dr. Kathleen Vigness-Raposa (Marine Acoustics, Inc.) and Dr. James H. Miller (University of Rhode Island) will discuss sound movement/propagation and sound measurement/signal levels as well as ocean noise measurement, variability, and noise budgets. Interested individuals must register in advance for this webinar.
