Ecosystems team

Our ambition

The scientific goal of our team is to understand the combined impacts of global climate-driven change and commercial fishing on polar marine ecosystems. Our research will provide fundamental insight into the response of species and ecosystems to change and enable us to detect and project their responses to future change.   Our research is critical to the development of conservation and ecosystem-based management strategies and will contribute to the development of Government policy.

Our research is focused on understanding the effects of change on whole ecosystems from microbes to whales and from local to circumpolar ecosystems. Our two research groups (Pelagic Ecosystems and Higher Predators and Conservation) focus on the Scotia Sea/West Antarctic Peninsula region, which is affected by both rapid climate-driven changes and major fishing activities. Comparative studies of Arctic and Southern Oceans will also advance our understanding of the Polar Regions, their influence on global cycles and ecosystems, their response to change, and methods for their effective conservation. Our innovative multidisciplinary approach and international leadership and partnerships will ensure that we continue to strengthen this area of globally important research.

Team priorities


  • Understanding the life-cycles of polar marine species. To develop a quantitative understanding of the life-cycles, distribution and abundance of key species.
  • The structure and functioning of polar ocean ecosystems. To understand the biological-physical-chemical interactions that determine the structure and functioning of ecosystems from local to circumpolar scales from a food web perspective.
  • Impacts of variability and change. To understand the multiple drivers of change and the response of individual species and whole ecosystems.
  • Modelling ecosystems and future change. To develop models of key species and ecosystems for projecting the impacts of future change on polar ocean ecosystems.
  • Fisheries and conservation in areas of rapid change. To use our understanding of the interactive effects of harvesting and climate-driven change to develop sustainable management and conservation approaches.

Technology, innovation and training

  • Conduct large-scale multidisciplinary field experiments from ships and land-bases and develop and deploy advanced technology and autonomous systems for biological-oceanographic and ecological studies.
  • Develop innovative multidisciplinary approaches, encompassing genetics, biology and ecology of marine organisms (from plankton to the highest predators), biogeochemistry, oceanography, fisheries and climate science.
  • Targeted numerical modelling studies and analyses of long-term data series.

Influencing and leading international programmes

  • Work with national and international partners in Antarctic and Arctic research, including the Scientific Committee on Antarctic Research (SCAR), the Arctic Council and the Ecosystems Studies of Sub-Arctic Sea (ESSAS) programme.
  • Work in partnership with international partners and institutions to gain deeper understanding of human impacts (e.g. fisheries) on polar ecosystems, particularly through the Commission for Conservation for Antarctic Marine Living Resources (CCAMLR) in the Southern Ocean.
  • Lead the international Integrating Climate and Ecosystem Dynamics in the Southern Ocean programme (ICED) linking ecosystem and climate studies, developing links to the Intergovernmental Panel on Climate Change (IPCC) and the Intergovernmental Platform on Biodiversity and Ecosystem Services (IPBES).
  • Through our role in ICED, input polar perspectives into global science programmes, including the International Geosphere-Biosphere Programme’s (IGBP) Integrated Marine Biogeochemistry and Ecosystem Research (IMBER) programme, the Scientific Committee on Ocean Research (SCOR) and Future Earth.

 Stakeholder engagement

  • Produce essential scientific advice to underpin the development of UK government (Foreign and Commonwealth Office, FCO, and the Department for Environment, Food and Rural Affairs, DEFRA) and international conservation and management policies for the sustainable management of fisheries and human impacts in polar ocean ecosystems
  • Provide critical scientific evidence and advice to shape international policy development within the Commission for Conservation for Antarctic Marine Living Resources (CCAMLR)
  • Inform the Intergovernmental Panel on Climate Change (IPCC) and the Intergovernmental Panel on Biodiversity and Ecosystems Services (IPBES)

Public engagement in research

  • Disseminate our findings via publication in the highest-impact journals, through presentations in leading national and international forums
  • Participate in educational, media, business and stakeholder engagement activities.
