Mooring processing functionality

[oyvfoss]

The CTD profile functionality is starting to become useful. Want to create a similar framework for mooring data, starting with moored CTDs (SBE, RBR). For data parsing, the io.sbe may be used for SBE data (I haven't tested, but I assume we would need to extend the read_cnv function or make a parallel one. For RBR instruments, we should use the pyRSK module link - which has the added benefit of allowing us to skip the software UI and import directly from raw data (.rsk files).

Would be good to follow the principles from the CTD module - parsing to well-ordanized xr.Datasets and helping with the formatting end post-processing.

Some useful functionality (I am sure there is more):

• Parse from raw
• Spike removal (median filters, manual editing..).
• Time series and TS plots.
• Assign pressure to T-only instruments based on adjacent sensors.
• Resampling.
• Combining multiple data time series d(t) to an interpolated time series D(z, t).
• Viewers for diagnosing drift.
• Tools for comparing with CTD profiles and/or calibration casts
• Tool for applying linear drift

Re #12: May want to think carefully about what to put in e.g. a data.moored module vs in a data.edit or data.dataset module before starting this work..

There is now functionality in kval.file for importing moored RBR (.rsk) and SBE (.cnv) instruments. This should be an excellent starting point for a data.moored_ctd module. May want to stick to the model of data.ctd of calling specialized functions from a moored_ctd_tools submodule.

• Functions to apply to single records
  • Applying mooring-specific metadata -> Model on CTD functionality
  • Applying drift corrections -> Specific functions may also be of use in ctd -> put in edit?
  • Including to TIME if there is an offset on deployment!
  • Outlier editing -> Use
  • Threshold editing -> Should be able to reuse or share with ctd
  • Chopping ends -> We have this in the kobbe library..
  • Temporal filtering -> Runnig mean/medians..
• Functions on multiple records from the same mooring
  • Interpolation onto common time grids.
  • Depth interpolation going from N (TIME) moorings with a DEPTH(TIME) to a 2D (TIME, DEPTH) field.
  • Assigning depths on T-only sensors.
  • Look for static instabilities.
• Functionality for comparing with CTDs
• Visualization
  • Plotting the whole time series
  • Single sensor
  • Combined sensor
  • Distributions etc.
