Welcome to echopype!

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) leads this project and together with Kavin Nguyen (@ngkavin), Landung “Don” Setiawan (@lsetiawan), and Imran Majeed (@imranmaj) are primary developers of this package. Emilio Mayorga (@emiliom) and Valentina Staneva (@valentina-s) are also part of the development team.

Other contributors include: Frederic Cyr (@cyrf0006), Paul Robinson (@prarobinson), Sven Gastauer (@SvenGastauer), Marian Peña (@marianpena), Mark Langhirt (@bnwkeys), Erin LaBrecque (@erinann), Emma Ozanich (@emma-ozanich), Aaron Marburg (@amarburg)

We thank Dave Billenness of ASL Environmental Sciences for providing the AZFP Matlab Toolbox as reference for our development of AZFP support in echopype. We also thank Rick Towler (@rhtowler) of the Alaska Fisheries Science Center for providing low-level file parsing routines for Simrad EK60 and EK80 echosounders.
