New £10 million Changing Arctic Ocean research programme kicks off

Scientists on sea ice

More than 20 researchers from 16 UK research institutes, including the British Antarctic Survey, will join forces on board the RRS James Clark Ross to investigate the knock-on effects of rapid warming and sea-ice loss in the Arctic region.

Some of the clearest signs of change are the thinning and retreat of sea ice and the migration of species into the Arctic that normally live at lower latitudes. These changes are likely to have an unprecedented impact on how the Arctic ecosystem operates.

For example, as the fastest warming oceanic region in the world, the Arctic could be free of sea ice in summer within a few decades. This change is likely to affect the UK climate and economy, with anticipated impacts on industries like tourism and fisheries.

The UK scientists will contribute to international efforts to build a comprehensive picture of the constantly changing Arctic environment. They will look at a wide range of complex interactions between different organisms in the ocean and at the seafloor. Robotic underwater vehicles will also be deployed to collect data near the edge of the sea ice. Hundreds of litres of seawater will be filtered to capture phytoplankton, and special plankton nets will capture zooplankton, small animals that are an essential food source in the Arctic.

Dr Jo Hopkins, from the National Oceanography Centre and principal scientific officer on the ship, said:

This is an exciting and ambitious first research expedition that will collect a vast amount of information about Arctic water and sediments and the life they support. Improving our understanding of how the Arctic ecosystem functions today will help us better predict and manage how it may change in the future.

The ultimate goal of the NERC-funded Changing Arctic Oceans research programme is to generate a better understanding of the Arctic so models can more accurately predict future change to the environment and the ecosystem. Within the programme itself there are 76 scientists, with the lead investigators being from the Scottish Association for Marine Science and the universities of Leeds and Liverpool.

Four projects cover different aspects of the programme's goals:

  • the way change in the Arctic is affecting the food chain, from small organisms at the bottom to large predators at the top (the ARISE project)
  • how warming influences the single main food source at the bottom of the food chain (DIAPOD)
  • the effect of retreating and thinning sea ice on nutrients and sea life in the surface ocean (Arctic PRIZE)
  • the ecosystem at the seafloor (ChAOS).

Details of the research expedition and the research programme can be found on the Changing Arctic Ocean programme page.
