****apologies for cross postings**** The ocean is full of both natural and anthropogenic (human-made) sources of sound. Much attention has been focused on anthropogenic sound sources in the ocean and potential effects on marine mammals, fishes, and invertebrates. Regulators, decision makers, public affairs officers, industry representatives, other members of the international regulatory community, and others interested in underwater acoustics are invited to participate in the *Discovery of Sound in the Sea (DOSITS)* <https://urldefense.proofpoint.com/v2/url?u=http-3A__www.dosits.org&d=DwMFAw&c=dWz0sRZOjEnYSN4E4J0dug&r=JOrNtytRch_z3DSjtQDao1ePXGI6VzACNW5v0UqKIUM&m=Wa45HGxSFk3F8YptLVL3gg-wz35HduBFgq2w9__DyTg&s=E13Faah3TJm-4CmAX_6n-BUnklZyuP8aL7E1lAuGslU&e=> *free, four-part webinar series on anthropogenic underwater sound sources*. The webinars will include an overview of anthropogenic sound sources, including commercial shipping, pile driving, seismic sources, and sonar. Each webinar will last approximately 60 minutes and provide an update on current research efforts along with a review of noise mitigation measures. An extended period of facilitated discussion will also be included at the end of each webinar. Prior to each webinar, an outline of the presentation(s), with links to relevant background content on DOSITS, will be made available. *Participants are encouraged to review these outlines, as well as **archived webinars on the potential effects of underwater sound on marine animals* <https://urldefense.proofpoint.com/v2/url?u=https-3A__dosits.org_decision-2Dmakers_webinar-2Dseries_webinars-2D2018_&d=DwMFAw&c=dWz0sRZOjEnYSN4E4J0dug&r=JOrNtytRch_z3DSjtQDao1ePXGI6VzACNW5v0UqKIUM&m=Wa45HGxSFk3F8YptLVL3gg-wz35HduBFgq2w9__DyTg&s=-bh5xHHqeSQb_znfGZta6lAc2iKE6-vxziPqzukVPkk&e=>*, before each sound source webinar.* All webinars will be recorded and archived on the DOSITS website (*Decision Makers Webinars* <https://urldefense.proofpoint.com/v2/url?u=https-3A__dosits.org_decision-2Dmakers_webinar-2Dseries_&d=DwMFAw&c=dWz0sRZOjEnYSN4E4J0dug&r=JOrNtytRch_z3DSjtQDao1ePXGI6VzACNW5v0UqKIUM&m=Wa45HGxSFk3F8YptLVL3gg-wz35HduBFgq2w9__DyTg&s=atPYgjVIHwPgB1oJAQpOO0eOe09w7b_VsKwHCBv6hD4&e=>). A summary of questions asked, and their answers, will be posted online after each webinar. The first two webinars of this four-part series will take place in May 2019 and will focus on underwater sound associated with seismic sources, pile driving, and wind turbines. Subsequent webinars will take place in fall 2019 and will focus on commercial shipping, sonar, and echosounders. *Wednesday, May 1, 2019, 12:00 pm ET* - Dr. Robert Gisiner: Seismic Sound Sources *Wednesday, May 22, 2019, 12:00 pm ET* - Dr. James Miller and Dr. Kathleen Vigness-Raposa: Pile-driving - Dr. Jakob Tougaard: Wind Turbines *Interested individuals must register in advance for each webinar*. *To register please visit: https://dosits.org/decision-makers/webinar-series/webinars-2019/ <https://urldefense.proofpoint.com/v2/url?u=https-3A__dosits.org_decision-2Dmakers_webinar-2Dseries_webinars-2D2019_&d=DwMFAw&c=dWz0sRZOjEnYSN4E4J0dug&r=JOrNtytRch_z3DSjtQDao1ePXGI6VzACNW5v0UqKIUM&m=Wa45HGxSFk3F8YptLVL3gg-wz35HduBFgq2w9__DyTg&s=o2DPHITXDIZlcGtzH-lKKrJjd8Bke-WobDusyYciec4&e=>* To learn more about this webinar series or to view previous webinars or other, upcoming webinar dates and speakers, please visit the DOSITS webpage, *Decision Makers Webinars* <https://urldefense.proofpoint.com/v2/url?u=https-3A__dosits.org_decision-2Dmakers_webinar-2Dseries_&d=DwMFAw&c=dWz0sRZOjEnYSN4E4J0dug&r=JOrNtytRch_z3DSjtQDao1ePXGI6VzACNW5v0UqKIUM&m=Wa45HGxSFk3F8YptLVL3gg-wz35HduBFgq2w9__DyTg&s=atPYgjVIHwPgB1oJAQpOO0eOe09w7b_VsKwHCBv6hD4&e=>.
