  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...
