Dear friends and colleagues of AN2022, The 6th International Conference on the Effects of Noise on Aquatic Life (marine mammals, fish and invertebrates) will be held IN PERSON from July 10 to July 15 2022 in Berlin, Germany. Of course, we are monitoring the situation for COVID and in the Ukraine, and appropriate adjustments will be made as directed by the authorities. Backup plans are in place if restrictions make it impossible to meet, including adjustment of registration fees. We have had great interest in submission of papers to AN2022. That bodes well for the meeting. However, several colleagues have requested an extension for submission of abstracts. Therefore, we are extending our final deadline until April 15, 2022. We cannot accept any contributions after that date. Best regards, AN2022 Organising Committee: Frank Thomsen, Chairman (frth@dhigroup.com) Arthur Popper Anthony Hawkins Joseph Sisneros Paul Lepper Amy Scholik-Schlomer
