echostack is an open-source ecosystem of interoperable Python packages for processing, analyzing, visualizing, and managing scientific echosounder data.
The ecosystem provides modular and scalable software components for working with water-column sonar data, from raw instrument files to calibrated, analysis-ready data products and downstream ecological interpretation.
Built on the Scientific Python ecosystem, Echostack leverages libraries such as xarray, Dask, Zarr, NetCDF, fsspec, and pandas, while integrating with community projects including regionmask, HoloViz, Prefect, and Pydantic.
The Echostack ecosystem builds upon the development of echopype:

The Echostack ecosystem is designed to be:
- Modular: repositories can be used independently or combined into larger workflows.
- Interoperable: built upon the Scientific Python ecosystem and common open data formats.
- Scalable: from personal laptops to HPC clusters and cloud platforms.
- Open: community-driven, reproducible, and open-source.
We welcome contributions from researchers, developers, and users of ocean acoustic data.
