A five-year global research programme

The Convex Seascape Survey is an ambitious research programme providing critical data and insight on what the world needs in order to fully incorporate the ocean into policy efforts to slow climate change. It builds on two successful, high-profile science programmes that have found incontrovertible evidence that climate change is already causing major disruption: The Catlin Arctic Survey highlighted the alarming thinning of Arctic sea ice, and The Catlin Seaview Survey showed serious, widespread degradation and decline of the world’s coral reefs in the face of global warming.

Our cross-sector partnership has been fundamental to realising the interdisciplinary depth, global reach and resources needed to carry out this important work. Our international team brings expertise from many different fields (marine ecology, oceanography, geology, history, satellite telemetry, environmental science, cartography, chemical and molecular analysis, and Earth system modelling) enabling the project to cross boundaries between disciplines and gain unique insights. We see this as a vital approach, given the interconnected nature of the seascape.

The questions we seek to answer

Seascape Carbon

Where is it, how and when did it get there and where did it come from?

Human Influences

Historical development and spread of human influences on the seabed

Marine Life

The role of life and biodiversity on seascape carbon stores and benefits of protection

United Kingdom

Scotland

In Millport, laboratory mesocosm experiments are used to quantify bioturbation for different benthic species and study the associated effects on carbon capture and burial. In the South Arran Marine Protected Area a sampling campaign compares marine life recovery and carbon storage with areas outside which are subject to bottom fishing.

Irish Sea

In the Western Irish Sea mud belt, aboard research vessel Celtic Explorer, sediment coring and sub-bottom profiling was conducted. Samples undergo grain size and carbon content analysis and will be used to test and validate predications from the hydrodynamic model which predicts past and present extent of continental shelf muds.

North Sea

For the Fladen Ground case study on carbon accumulation in the North Sea, age-depth modelling of seabed sediments is carried out and sediment cores are analysed for grain size and total organic carbon.

Jersey - Channel Islands

A sampling campaign in a cable protection zone and outside in areas subject to trawling and dredging. Methods include Baited-remote underwater video, Remotely operated vehicles, sediment grabs and cores collected via scuba. Additionally, more than 60 vibrocores and multicores were retrieved, for carbon content and environmental DNA analysis to measure the relation proportion of carbon inputs to the seabed.

Malaysia

Through our collaboration with OceanX we join a cruise throughout the Pahang coastal waters to study the effects of land use change on the sources and quantities of carbon stored on the Sunda Shelf. Sediment cores sub-sampled for grain size, total organic carbon, carbon isotope analysis, carbon/nitrogen ratios and environmental DNA.

Antarctica

Expedition to collect sediment cores from the Antarctic in order to look for signals of whale abundance using environmental DNA and explore the relationship with historic population trends and ocean productivity and carbon sequestration.

New Zealand

A sampling campaign in the Hauraki Gulf cable protection area and outside in areas subject to trawling and dredging. Methods included Baited-remote underwater video, Remotely operated vehicles, sediment grabs and coring.

Where we are working

Research is underway in a wide range of places, so we can extrapolate observations and measurements from particular sites to regional and global scales.

Across major ocean biomes, from the tropics to the poles, our regions of interest include: Patagonia, Indonesia, South Africa, New Zealand, Turkey, Australia, Canada, Jersey, Scotland, and the Antarctic.
