Dr Helen Findlay is a biological oceanographer who uses a combination of experimental, observational and modelling tools to investigate the impacts of climate change and ocean acidification on marine organisms and ecosystem functioning. She has an interest in understanding the biological, physical and chemical interactions within the marine environment, specifically relating to carbon biogeochemical cycling, with a particular focus in Arctic regions.

Helen was the first recipient of the PML Lord Kingsland Fellowship, allowing her to continue her research on ocean acidification in both temperate seas and in the Arctic. She is currently involved in the UK Shelf Seas Biogeochemistry Programme; participating on the cruises to investigate nutrient and carbon biogeochemical cycling in sediments. Helen was involved in the UK Ocean Acidification project, offering advice for setting-up and running long-term CO2 experiments, and is lead PI on an Arctic project Ocean Acidification in Arctic Fjords. Helen facilitates PML's carbon chemistry research, with an aim to understand short-term variability relating to ocean acidification and climate change.

Helen is also involved in the outreach of marine science to schools and educators, working alongside Digital Explorer and the Royal Geographical Society (with IBG) to promote ocean learning in the classroom.
