The Ocean Acoustics CIRES team embedded at the NOAA National Centers for Environmental Information manages two marine acoustic archives for the long-term stewardship of globally collected water column sonar and passive acoustic data for widespread access. These vast datasets are collected from across NOAA and academia, each serving a unique scientific purpose. Data providers submit their data with the help of the team's custom packaging software tools. Streamlined ingest of received data packages is facilitated by the archive's robust pipeline that leverages automation, outage resilience, and logging. Users from across the globe can discover, query, and access archived data using the archives' web-based map viewers. Further, 750+ TB of publicly accessible archived datasets are available in cloud buckets provided through the NOAA Open Data Dissemination Program. This enables free and immediate download of desired data and allows users to bring processing routines to large volumes of data - from simple statistical analyses to artificial intelligence. Through open access to large centralized repositories, researchers are empowered to address new questions that will advance the field of marine ecosystem acoustics and to apply these data in ways that are yet to be thought of.
