Description: From August 9 - September 19, 2025, the icebreaker Oden carried out an expedition with the Canadian icebreaker CCGS Louis S. St-Laurent to map the seabed in the Arctic Ocean, which took place within the framework of the UNCLOS program (United Nations Convention on the Law of the Sea). In symbiosis with this, an extensive Early Career Scientist program also took place on board, consisting of the course The Arctic Ocean Climate System.

The parameterlist is described in the documentation files "Parameterlist FerryBox AO25 2025.csv" and "Parameterlist FerryBox AO25 2025.pdf" - "Ferrybox data AO25 2025.zip" - ferrybox data with measurements of physical, chemical, and biological parameters in seawater while the vessel is in operation. The parameterlist is described in the documentation files "Parameterlist Ferrybox AO25 2025.csv" and "Parameterlist Ferrybox AO25 2025.pdf" In addittion, "Shiptrack A025 2025.geojson" provides a track of the ship's position every 10 minutes. Datafile descriptions ---------------------- "Shipdata AO25 2025.zip" contains comma-seperated-variable files with filenames in format "Oden-Allids-2025-08-22.csv" and CRLF endings. "Ferrybox data AO25 2025.zip" contains tab-seperated-variable files with filenames in format "All_sensors_732302_2025-09-02.txt" and LF endings. All csv and txt files ISO 8859-1 encoded. Ferrybox data files have a heading and are structured as follows. Line numbers are given for reference, they are not part of the heading. 1 - $METADATA 2 - $Version 1.1 3 - $Project; FerryBox 4 - $Device; 732302 5 - $DateTime;
