We use the icebreaker Oden for research expeditions in the Arctic during the summer. An expedition generally lasts between three to six weeks, and Swedish and international researchers accompany the expeditions. On board Oden, there is basic equipment that is always included in all expeditions that the Swedish Polar Research Secretariat, together with partners, are responsible for. It applies to meteorological parameters such as temperature, wind speed and cloud height; oceanographic parameters such as water temperature, salinity and conductivity; as well as ship data such as longitude, latitude and icebreaker speed. In total, there are approximately 150 sensors on board.
