Features

• Read RSK (.rsk) and Castaway (.csv) files and extract CTD data
• Process CTD data, including removing non-positive samples and cleaning data
• Calculate derived quantities such as absolute salinity, density, and potential density
• Determine mixed layer depth (MLD) using different methods
• Generate plots for visualizing CTD profiles and derived quantities
• Command-line interface (CLI) for easy processing and merging of RSK files

Installation

It's recommended that you create a new environment just for ctdfjorder. This can be done in conda with the following command.

conda create --name ctdfjorder python=3.11
conda activate ctdfjorder
