Dr Clare Woulds
I am Professor of Marine Biogeochemistry, with expertise in benthic biogeochemistry, organic geochemistry, and stable isotope tracing. My research is broadly concerned with studying the biogeochemical processes occurring in marine sediments, with an emphasis on the cycling and burial of organic carbon, and the role played by benthic fauna in shaping their own geochemical environment. Work in low oxygen environments such as the Baltic Sea and the Arabian Sea has led to a particular interest in de-convolving the often co-varying factors of sediment organic matter content, dissolved oxygen concentration and benthic faunal community biomass and structure in determining the early diagenetic pathways of organic carbon. I investigate short-term benthic c-cycling using stable isotope tracer experiments, which I have conducted in a wide range of settings from intertidal sands to deep-sea sites in the Southern Ocean. I have also worked in sedimented chemosynthetic environments, investigating C sources for benthic ecosystems. Current projects include manipulative experiments to investigate the impacts of climate change stressors and microplastics on benthic community biogeochemical function, investigation of the mechanisms governing C burial in marine sediments, and characerising the environmental baseline and potential impact on sediment biogeochemistry of proposed deep-sea mining.
