There are currently unresolved issues related to matching echopype pulse compressed Sv with those generated by Matlab code and EchoView. The Matlab and Echoview pulse compression outputs are also different....

computation

It is a pretty common need to regrid Sv data, since different channels (frequencies) may be configured differently to collect data with different `sample_interval` even if the total range collected...

processing functions

The v0.6.0 change of netCDF data structure did _not_ include the Nortek Signature ADCP (AD2CP) data, because the data is of substantially different format compared to the EK and AZFP...

data format

The operation in `compute_MVBS` is basically to compute a 2D binned average of Sv along `echo_range` and `ping_time`. Note that the average should be done in the linear domain (sV)...

enhancement

NASC (nautical area backscattering coefficients) is a high-level data product intimately related to biomass estimation. It can be viewed as a cleaned up form of the acoustic data (after removing...

computation

Given an existing bottom annotation generated from either manual editing or automatic detection, we need a function to remove everything below the bottom before computing NASC. For this function it...

computation

This is not currently used by the hake survey but is used by NEFSC in multiple years. This is not difficult to implement and in theory straightforward to parallelize. Would...

processing functions

A function to remove impulsive noise like those produced by un-synced ADCP or electric noise is useful is batch processing data.

processing functions

Right now we have both single and double backtick quotes for variables in our documentation and docstring. It renders the same way in GitHub markdown, but in sphinx it was...

good first issue
docs

`DEFAULT_CHUNK_SIZE` is curiously declared in two different places: `echopype/convert/set_groups_base.py` and `echopype/convert/api.py`. It is only used in 1 place for single file handling (`SetGroupsEK60.set_platform`) and does not seem to be used...
