**apologies for cross postings** 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; www.dosits.org <http://www.dosits.org/>) Team is facilitating a free, five-part webinar series for the international regulatory community on topics related to underwater sound. The first webinar in this five-part series was a great success! Registration is now open for the second webinar in this series. During this 60 minute webinar, Dr.’s Clara Amorim and Darlene Ketten will discuss marine animal sound production and reception. Content will be derived from peer-reviewed research. A period for question and answer will occur after the presentations have been completed. This webinar will be held on Thursday, December 3, 2015, at 12:00pm ET. Interested individuals must register in advance for this webinar.
