Biogeochemical cycles

The ocean plays a dominant role in the Earth’s carbon and nutrient cycles. These cycles are intrinsically linked together and sustain life in the ocean and form a key part of our climate system.

  Closing the budget in marine atmospheric Oxidative Capacity through the quantification of Oceanic VOC emissions (COCO-VOC)

  Roughly half of the oxidation of methane (a key greenhouse gas) and non-methane volatile organic compounds (VOCs) occurs over the oceans via reactions with the hydroxyl radical (OH). Some of these reactions lead to secondary organic aerosols (SOA), which are important for cloud formation, and ozone,...

  Biological Pump and Carbon Exchange Processes (BICEP)

  Project start: January 2020 – currently ongoing The ocean carbon cycle is a vital part of the global carbon cycle. It has been estimated that around a quarter of anthropogenically-produced emissions of CO2, caused from the burning of fossil fuels and land use change, have been absorbed by the...

  Changing Arctic Carbon cycle in the cOastal Ocean Near-shore (CACOON)

  The Arctic Ocean is a rapidly changing environment, with rising temperatures leading to an ongoing decline in sea ice and shifting conditions for marine life. Despite the presence of important and complex ecosystems in Arctic waters, there are knowledge gaps in how the Arctic Ocean and its inhabitan...

  Land ocean carbon transfer (LOCATE)

  Our climate, and hence our lifestyle and economy, is profoundly influenced by the concentration of carbon dioxide in our atmosphere, which regulates the amount of heat which arrives on earth from the sun that returns to outer space.
