Dr Jason Holt
I specialise in the synthesis of model and observations to develop our understanding of shelf-sea physical and coupled physical-biological systems. Particular areas of interest include model capability and accuracy; the impact of large scale variability (e.g. climate change) on shelf-sea physics and ecosystems; and transports and budgets of water, carbon and nutrients across shelf sea basins. I have worked in close collaboration with the UKMO for over 10 years on developing shelf sea models for operational oceanography and climate downscaling (e.g. UKCP09).
