CTD data processing, classic method

Originally written by Yannick Kern. Procedure developed together with Paul Dodd.

This repository contains documentation and code for the classic CTD processing procedure at NPI.

The procedure, described here, involves:

• Creating dataset-specific configuration files in the SBE Data Processing software.
• Running SBE processing on a CTD dataset using Windows batch scripts.
• Quality control of the data in Matlab.
• Conversion to CF-formatted NetCDF using the NetCDF-creator tool.

NOTE:

An alternative procedure, using Python and not reliant on proprietary software, is under development. This alternative procedure is highly experimental, and the classic procedure is currently the recommended way of processing CTD data.

Instructions

All the relevant datasets can be found on data.npolar.no using:

List of script file extensions

• Matlab .m files: convert instrument data .cvn into Matlab .mat arrays/binaries
• .json config files for NetCDF-Creator software to convert Matlab .mat into NetCDF4 .nc files
• batch .bat files that start Seabird sbebatch processing terminal/software
