My work is focused on Southern Ocean remote sensing, the use of current ocean colour products and the development of tailored regional products to address large-scale circumpolar research questions. I have developed new and improved chlorophyll algorithms for the Southern Ocean and I am currently working on improving remote sensing techniques for quantifying calcite (from Coccolithophores) and phytoplankton functional types in the Southern Ocean.
At the centre of all my work is the microscopic life that lives in the sea – the phytoplankton. Phytoplankton are the small microscopic plants responsible for almost half the photosynthesis and primary production on our planet. Through photosynthesis these tiny organisms produce oxygen and soak up carbon in every body of water on earth. Consider that the oxygen in every second breath we take comes from phytoplankton and their vital importance to our everyday lives and the health of the planet becomes apparent.
