Abstract
The NOAA National Centers for Environmental Information maintains two marine acoustic archives for the long-term stewardship of globally collected water-column sonar and passive acoustic data. These vast datasets are collected across NOAA and academia for a wide range of scientific objectives. The archives document the datasets using standards-driven metadata and preserve them on long-term storage systems. Users can discover, query, and access archived data using the archives’ web-based map viewers. Further, cloud-based access to 200 + TB through the NOAA Big Data Program 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. Cloud-based tools are being developed in collaboration with our partners in the ocean acoustic community to visualize and analyze data in the archives. This allows researchers of varying backgrounds to easily understand the quality and content of these complex data. Providing free access to data archives and facilitating the utility of these data increases the potential for researchers to address new questions that will advance the field of marine ecosystem acoustics.
