Ocean-Nav

This repository contains the development of two acoustic variables

• Potential Sub Surface Channel which conveys the existence of a subsurface channel from a given sound speed profile.
• Slope of Sound Profile, that will indicate the amount of sound wave that is trapped inside a sound channel.

Notes

Potential Sub-Surface Channel

• Create the 1D sub-surface channel detection routine

• Integrate frequency cutoff variable and ΔC calculation

  • Write a function to calculate ΔC from a given sound speed profile and fixed frequency cutoff
  • Write two versions of the ΔC calculation routine, with given frequency cutoff and a fixed frequency cutoff
  • Get feedback from DND

• Prepare the routine to integrate with ONAV

  • Transform the routine to an n-dimensional form to be able to used as derived variable in ONAV
    • Prepare the delC calculation routine to return ndarray instead of a single value
    • Prepare the sub-surface channel detection routine to return an ndrray of boolean which will indicate the existence of sub-surface channel
  • Insert the PSSC Routine to navigator's functions.py file
  • Test in staging and decide the colormap
  • Push this derived variable to production

Slope of Sound Profile

• Move the POC slope of something code to a seperate Jupyter Notebook
• Share the notebook and queries we have for them with DND
• Waiting for DND's feedback on the questions.
