Ice floe about the size of 300 football fields and up to six metres thick. The ice floe needs to be, on the one hand, substantial enough to carry all the equipment and, on the other hand, thin enough to be drilled through for the unterwater vehicle (see 16) and the ice cores (see 19).
Deep-sea probe: Collects water samples at depths up to 1,000 metres to study microorganisms, among other things.
Helicopter deck: From here a weather balloon is launched four times a day to heights up to 25 kilometres, sending back meteorological data.
Ship's bridge and meteorologist's duty room.
PSI research container with air intake
Radar and lidar: Cloud radar and particle laser radar for remote measurement of atmospheric data such as the height of the clouds.
Wet lab: Here seawater samples are analysed and ice cores are melted and tested.
Common room «Odenplan»
Canteen: The room for meals as well as the meteorologist's daily briefing at 8:15 a.m.
Gangway: Pulled up at night so no polar bears will wander onto the ship. Every morning at 6:00 a.m., the official polar bear guard makes her rounds to check the ice floe.
Underwater vehicle: A domed tent protects a hole drilled in the ice floe, through which a remotely controlled underwater vehicle is lowered into the water at regular intervals. It gathers data on how much light shines through the ice floe and where colonies of microorganisms form.
Anchored measurement balloon: Released several times a day on a line 1.5 kilometres long to collect data on aerosols, among other things.
Between the ice floes instruments measure how much sea salt rises into the air.
Ice cores are extracted from the ice floe to be studied on board the Oden.
