⭐ Features

• Read RBR (.rsk) and SonTek 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 CTD data 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=3.12
conda activate ctdfjorder

To install ctdfjorder you can use pip:

pip install ctdfjorder

🚀 Usage

CTDFjorder provides a command-line interface (CLI) for processing and analyzing CTD data in addition to serving as a python library. A tutorial has been setup here for running the CLI.
