Echopype is a package built to enable interoperability and scalability in ocean sonar data processing. These data are widely used for obtaining information about the distribution and abundance of marine animals, such as fish and krill. Our ability to collect large volumes of sonar data from a variety of ocean platforms has grown significantly in the last decade. However, most of the new data remain under-utilized. echopype aims to address the root cause of this problem - the lack of interoperable data format and scalable analysis workflows that adapt well with increasing data volume - by providing open-source tools as entry points for scientists to make discovery using these new data.
Wu-Jung Lee (@leewujung) founded the echopype project in 2018 and continue to be the primary contributor together with Praneeth Ratna(@praneethratna). Emilio Mayorga (@emiliom), Landung “Don” Setiawan (@lsetiawan), Brandon Reyes (@b-reyes), Kavin Nguyen (@ngkavin) and Imran Majeed (@imranmaj) have contributed significantly to the code. Valentina Staneva (@valentina-s) is also part of the development team.

We thank Dave Billenness of ASL Environmental Sciences for providing the AZFP Matlab Toolbox as reference for developing support for the AZFP echosounder, and Rick Towler (@rhtowler) of the NOAA Alaska Fisheries Science Center for providing low-level file parsing routines for Simrad EK60 and EK80 echosounders.
We also thank funding support from the National Science Foundation and NOAA Ocean Exploration, and software engineering support from the University of Washington Scientific Software Engineering Center (SSEC), as part of the Schmidt Futures Virtual Institute for Scientific Software (VISS) in 2023.
