The Discovery Of Sound In The Sea (DOSITS) offers a Certificate of Professional Development in association with the DOSITS Underwater Acoustics Webinar Series. All webinars incorporate effects of sound on marine mammals. There are no fees associated with this certificate. There is still time to earn a 2025 certificate. Interested individuals must have completed two steps: 1) Participate in all four of the webinars in the 2025 series (either via the live webinar events or watching webinar recordings). 2) Complete a brief, post-webinar questionnaire. Each webinar has its own questionnaire to complete available on the webinar pages. The questionnaire links will be available until Friday, December 5, 2025. Please note: individuals must use the same full name and email address in all four certificate questionnaires to ensure the DOSITS Team can verify your participation. * Marine Invertebrates and Sound<https://wp.me/P7HBT0-7sJ> April 30, 2025 Marta Solé, UPC (LAB) * Wildlife and Offshore Wind<https://wp.me/P7HBT0-7t5> June 4, 2025 Dr. Aaron N.
