v0.7.0

Overview

This release includes new features to interface with Echoview ECS files for computing Sv, reorganization of computing functions into new subpackages, addition of data processing level attributes to data products, and other improvements and bug fixes.

New features and major changes

• Allow using ECS for calibrating Simrad echosounders (#996, #1004)
  • This functionality is in a beta testing stage
  • Details of implementation may change and bugs are possible
  • Expand ECS parser to accept frequency-dependent values in EK80 ECS files
• Overhaul env_params to ensure correct intake for calibration (#985)
  • Now allows using env_params entries that are xr.DataArrays
• Move functions previously in preprocess subpackage to new subpackages (#993). Calling these functions from preprocess is deprecated and will be removed in v0.7.1.
  • clean: remove_noise, estimate_noise
  • commongrid: compute_MVBS, compute_MVBS_index_binning
• Add commongrid.compute_NASC (#1005)
  • The current implementation uses brute force looping for mean Sv computation, this will be refactored and optimized together with other functions requiring the same pattern in an upcoming release
• Add global attributes for data processing levels (#1001).
  • This functionality is in a beta testing stage
  • See data processing level specifications for functions and conditions under which such attributes are added
• Expand mask.apply_mask to handle multi-channel Sv datasets (#1010)
• Standardize sonar metadata for EK80 data (#992)
  • sonar_serial_number is now an empty global attribute, no longer a variable, as in the EK60 case
  • transducer_name, transducer_serial_number, transceiver_serial_number based on parser parameter transducer_name, transducer_serial_number, and serial_number, respectively

Bug fixes

• Fix scaling bug for beamwidth_alongship and beamwidth_athwartship from CW-based parameters to values corresponding to center frequency of broadband transmit signals (#998)

Tests and infrastructure

• Add more comprehensive tests for add_location (#1000)
• Add test for splitbeam angle ek80_CW_power case (#994)
• Add unit and integration tests for env_params intake for calibration (#985)
• Exclude test_data folder in codespell pre-commit hook (#1016)
