***apologies for cross-postings*** The application for the Ocean Observatories Initiative <https://oceanobservatories.org/> Facility Board's (OOIFB <https://ooifb.org/>) *2025 Summer School on Acoustics* <https://ooifb.org/2025-ooifb-acoustics-summer-school/> *will close* in a little over two weeks, on *March 18, 2025*. This *5-day, in-person*, intensive program will take place from *July 14-18, 2025, at the University of Washington in Seattle, Washington, *and will feature a mix of targeted lectures and hands-on exercises working with real-world examples and NSF OOI data (focusing on the access, analysis, and interpretation of acoustics data as well as complementary oceanographic data available through the NSF OOI*)*. Please note: there are no registration fees associated with this program, and *travel support is available for participants from U.S. institutions*. Participants can expect to finish the 5-day program with: - A high level understanding of how sound propagates under water and the main factors influencing propagation. - An awareness of passive and active acoustic instruments deployed through NSF OOI and the data sets available. These instruments include echosounders, current profilers, bioacoustic sonars, broadband hydrophones, and low frequency hydrophones, the data from which can be applied in many ways, such as detecting and characterizing sounds produced by marine mammals, fish, and humans; zooplankton migration; and characterizing ambient sound in the ocean. - The ability to navigate NSF OOI data portals to access and download acoustic and oceanographic data products. - Basic processing methods for acoustic data (including coding, and working with data in JupyterHub environments). - A comprehensive understanding about what scientific questions can be addressed using NSF OOI data. - Connections to a network of professionals who are using or planning to use NSF OOI data in their research and education activities. *For more details on program requirements, eligibility, a draft agenda, and online application, please visit the* *OOIFB Summer School on Acoustics webpage: https://ooifb.org/2025-ooifb-acoustics-summer-school/ <https://ooifb.org/2025-ooifb-acoustics-summer-school/>. * Please continue to share this opportunity widely across your networks!
