This repository contains scripts for getting/processing data from Orcasound and Ocean Observatories Initiative (OOI) hydrophones and corresponding GitHub Actions workflows.
For introduction to GitHub Actions see here.
Orcasound GitHub Actions workflow (located at .github/workflows/orcasound_processing.yml) has manual trigger dispatch_workflow. It downloads the full timestamp "directory" from Orcasound AWS bucket (see more here) and processes each file individually. For now you will have to manually change timestamp in the workflow file. If you want to change processing from creating spectrograms to something else look for the loop for input_wav in sorted(glob.glob("wav/*.wav")): at the end of the source file (orcasound_processing.py).
Ocean Observatories Initiative GitHub Actions workflow (located at .github/workflows/ooi_processing.yml) runs at 12:00 UTC every day (schedule event trigger). By default it will attempt to download data in 5 minute length chunks for the previous day and create spectrograms for this data, saving spectrograms in the spectrograms directory. These spectrograms are then uploaded as artifacts of the run. In addition to scheduled runs, this workflow can be triggered manually through GitHub web interface, GitHub CLI or REST API (see here).
Manual workflow runs support setting inputs: node, start time, end time and segment length. Default node is PC01A. Segment length can be fractional. To change output directory modify environment variable OUTPUT_DIR in the workflow file.
To change processing of the data you will need to modify Python source code (ooi_processing.py). Processing loop is in thesave_ooi_spectrograms function, add your processingsteps after the line hydrophone_data.wav_write(wav_name) if you want to work with .wav file.
