Research Interests

My primary research interest is in understanding changes in ocean colour which are driven by microscopic particles and dissolved materials present in the water column. Ocean colour remote sensing allows observation of the oceans’ ecology on the global scale which is essential for understanding the factors affecting complex marine ecosystems. I have developed a keen interest in using satellites to distinguish what materials are the major drivers effecting the light in coastal and oceanic ecosystems, from suspended sediments to phytoplankton to dissolved organic matter. A major part of my work is therefore in developing algorithms to provide more accurate measurements of parameters from satellite measurements, be it optical properties, the separation of suspended sediment and phytoplankton signals in shelf seas or the concentration of particulate inorganic carbon in the global ocean.
