Using these samples the team were able to calculate carbon and nutrient levels and supplies, the transportation of greenhouse gases between the shelf sea and the atmosphere and the amount of carbon transported to the adjacent deep ocean.

Jonathan Sharples, Professor of Ocean Sciences, who headed up the research consortium, said: "This research programme has given us an unprecedented picture of the seasonality of life in the shelf seas, and the underpinning physics and chemistry.
