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) <http://www.dosits.org/> Team has been facilitating a free, five-part webinar series for the international regulatory community on topics related to underwater sound. The fifth and final webinar in this series will provide a brief summary of the previous webinars, and offer an opportunity for participants to follow up on the topics presented and ask additional questions. A panel of previous webinar speakers will be online and available to answer questions. We are requesting that individuals submit questions in advance, although some time will be allotted to answer questions asked during the webinar. The webinar will be held Thursday, June 2, 2016, at 12:00pm (US East Coast time). To submit questions in advance, individuals must first register for the webinar (please note, if you do not plan on submitting questions in advance, but would like to participate in the webinar, you still need to register ahead of the webinar date).
