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 provides fundamental insight into the response of species and ecosystems to change that enable us to project and detect their future responses. This work 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 research groups consider different aspects of polar ecosystems and the services they provide: (i) the Ocean Ecosystems team examines the ecology of pelagic and mesopelagic organisms, such as copepods, krill and myctophid fish; (ii) the Higher Predators team focus on population dynamics and behavioural ecology of higher trophic level organisms such as penguins, flighted-birds, seals and whales; (iii) the Conservation and Management team considers the impact of both natural and man-made pressures on the Southern Ocean ecosystems and advises on policy to minimise these impacts. All three teams are inter-dependent and work collectively to meet the wider goals of the Ecosystems team. Our innovative multidisciplinary approach, combined with international leadership and partnerships, ensures that we continue to strengthen this area of globally important research.
Team priorities
Science
- 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.
- 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 International Arctic Science Committee (IASC).

- 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 Commonwealth and Development Office, FCDO, 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.
