Oden data repository

The Swedish icebreaker Oden has served as a research vessel for expeditions to polar regions, in both Arctic and Antarctic waters, since 1991. Facilities on board include scienti­fic laboratories, space to install research containers and deep ocean winches. This enables scientists to carry out research in different disciplines.

Meteorology

Data from the atmosphere to aid in understanding weather and climate processes such as cloud formation, surface energy balance and ice melt, and Arctic amplification. This includes for example, aerosol, micrometeorology and radiosounding data.

Oden is equipped with an extensive meteorological observatory that operates on most expeditions, including in situ and remote sensing instrumentation such as an air-sea turbulent flux package, weather station, microwave radiometer and cloud radar. Additional instrumentation such as those for sampling aerosol is deployed for particular expeditions.

Marine geology

Marine geology includes studies of the geology and history of the oceans using marine sediment archives. The related subject of Marine geophysics focuses on the mapping of ocean floor surface landforms and sub-surface geology.

Swedish icebreaker Oden has the capacity of conducting marine geological field work in the ice covered polar regions. Long sediment cores can be retrieved from the aft deck. Oden is also equipped with a multibeam echosounder, sub-bottom profiler and mid-water split beam sonar.

Oceanography

Observations of the chemical, physical and biogeochemical properties of the ocean, including salinity, temperature, subsurface ocean velocities and nutrients, are fundamental for understanding the role of the oceans in the global climate system.

On most expeditions vertical depth profiles of conductivity, temperature and various other physical and chemical parameters are measured using CTD sensors and Niskin bottles. Current velocity profiles are sometimes measured from lowered acoustic Doppler current profiler. Data for a range of physical, chemical and biological parameters from underway surface water measurements are also available.

Biogeochemistry

Data relevant for understanding biogeochemical processes, including the couplings between biogeochemical cycles and climate change, the sources, degradation and processes of organic matter exported from river discharge and coastal erosion. Water column and sediment data may include concentrations of carbon and other elements, as well as their isotopic and molecular composition.

On most expeditions a wide array of water column sampling systems of gases, dissolved, colloidal and particulate components, as well as an array of sediment sampling systems are used to collect surface sediments and sediment cores.
