Dear MARMAM list members, I hope this message finds you well. Some of you have already answered our survey part one on the regulation of underwater noise and effect on marine biota (particularly on marine mammals) in the last two weeks. The feedback has been good so far and we have reached 43 experts from 14 countries around the globe. We are still missing feedback from Asia and Africa. To get more detailed data and especially find meaningful conclusions regarding future challenges to regulate underwater sound, we would now like to invite you again to take part 1 of the survey, but also to provide feedback for part 2 of the survey. We are planning to put the results into a publication and invite participating experts to join us on the author list. Who we are: We are Michael Dähne researching underwater sound and marine mammals for the last 15 years and my bachelor student Alexander Henning at the University Rostock, Germany. He is currently writing his bachelor thesis in Biosciences. Our goal: We would be truly grateful if you would consider participating in one or both parts of the survey – depending on what is most convenient for you. The surveys will take approximately 15 to 25 minutes each to complete, depending on your level of experience and familiarity with the national legal context. Deadlines: For Alexanders bachelor thesis, we are running on a tight timeline and would like to ask you to answer the surveys by July 5. An answer received afterwards can only be considered for the publication, but not for the BA-Thesis. LINKS: Here are the links for your convenience: * Part 1: <https://docs.google.com/forms/d/e/1FAIpQLSeD6IS8unzPo56rsGUo1HBCZfzqSLXWHjT XvtJmhdmxEO19sw/viewform?usp=header> https://docs.google.com/forms/d/e/1FAIpQLSeD6IS8unzPo56rsGUo1HBCZfzqSLXWHjTX vtJmhdmxEO19sw/viewform?usp=header * Part 2: https://docs.google.com/forms/d/e/1FAIpQLScpEGowYh2PwDkMqxLP0X46L-gAuHYe6BDo UndblIvqnCPdGA/viewform?usp=header The first part mainly refers to national guidelines on noise-intensive offshore activities, whereas the second part deals more with noise thresholds and your professional opinion on current efficacy of the regulation to achieve good conservation outcome. If you have any questions or encounter difficulties accessing the survey, please don’t hesitate to contact Alexander. He will be more than happy to assist. With sincere thanks and kind regards, Michael Dähne and Alexander Henning University of Rostock, Department of Biosciences alexander.henning@uni-rostock.de <mailto:alexander.henning@uni-rostock.de>
