Overview

This is a release that includes important performance enhancements that allow user-provided calibration parameters for broadband and narrowband calibration, new functionalities to compute and attach split-beam angles to calibrated Sv dataset, perform frequency-differencing and masking, as well as a number of bug fixes and other improvements.

New features

  • Allow passing in cal_params as a dictionary for narrowband and broadband calibration (#955)
  • Add default chunk encoding for zarr output (#939)
  • Add add_splitbeam_angle function to the consolidate subpackage (#916, #971)
  • Add a new mask subpackage
    • Add apply_mask function to the mask subpackage (#912)
    • Add frequency-differencing function to the mask subpackage (#901)
  • Allow selection of a subset of channels when combining multiple echodata objects (#892)
    • This is done via the added channel_selection input argument to combine_echodata
  • Add default consolidated flag for echodata.to_zarr (#855)
  • Generalize and improve efficiency of compute_MVBS (#878)
    • Allow echo_range that vary with ping_time
    • Allow Sv data that are dask arrays
  • Add .nbytes to obtain that data size of an echodata object (#874)
  • Add new data variables from the raw data files to facilitate EK80 calibration (#944)
    • transceiver type, transmit impedance, receive impedance, receiver sampling frequency

Enhancements and other changes

  • Unify the order of dimensions of echo_range across all sonar models (#968)
  • Create and use the default echopype home directory (#896, #954)
    • This default directory is at ~/.echopype
  • Refactor the calibrate subpackage (#904)
    • routines for env_params and cal_params intake and range computation are now in different modules rather than methods in each classes
    • Tidy up cal_params related routines (#953)
    • Revise env_params related routines (#952)
  • Improving pulse compressed broadband Sv computation and echo range computation (#944)
    • The resulting values are tested against pyEcholab and Echoview outputs
    • Note there is unresolved discrepancy between pyEcholab/Echopype outputs with Echoview outputs for the first section of Sv values
  • Change input argument names for open_raw (#962)
    • Change offload_to_zarr to use_swap
    • Change max_zarr_mb to max_mb

Bug fixes

  • Handling of provenance attributes in apply-mask and add-depth, especially for testing (#930)
  • Fix bugs in combining multiple echodata objects (the combine_echodata function)
    • Fix meta_source_filenames bug and enable (meta)source_filenames appending of path and list (#913)
  • Fix bugs in env_params intake for calibration (#952)

Infrastructure

  • Update docker build for arm64 mac silicon chips (#964)
  • Fix windows github actions workflow (#947)
  • Remove mamba dependency (#946)
  • Fix pre-commit ci and update RTD config for jupyter-book (#934)
