Dr Andy Rees is a senior research scientist, leader of the UK Atlantic Meridional Transect (AMT) project and the coordinator for PML impact activities related to the promotion of “Cleaner Seas for Nature and Society”. He is a biogeochemist who has participated in and led research projects and oceanographic expeditions on a global scale including to Arctic and Antarctic regions.

Andy's research interests focus on biogeochemical cycling in the marine environment and on the impact of environmental change on the biological and chemical processes which control the ocean and atmospheric exchange of greenhouse gases. Recent research projects include the impact of environmental change on the marine nitrogen cycle, the activity and distribution of nitrogen fixing organisms and the sea-air flux of nitrous oxide and methane between river catchments and the open ocean.

Andy and colleagues are currently investigating the impact of ocean acidification, warming and sea-ice retreat in Polar waters and the transport of carbon and nutrients between the UK land-mass and our coastal seas. He leads and manages scientific programmes which range in scale from 2 to 3 people to multi-institutional involvement over periods of two to ten years and has published over 80 peer reviewed research papers.
