Diatom silica production under future ocean conditions, genes to biomes

Start year: 2021

Summary: This project aims to reveal how climate change will influence the cycling and transfer of carbon and silicon in the ocean by quantifying changes in diatom community composition and silica production with concurrent warming and acidification. This project expects to deliver new knowledge on diatom silicate production and marine carbon and silicon cycling in a future ocean using the interdisciplinary approaches of physiology, molecular biology and quantitative modelling. Expected outcomes include improved estimates on marine productivity and a redefined understanding of threats to marine life from ocean acidification. This should provide significant benefits such as improved valuations on the sustainability of ocean ecosystems.
