Dr John Aldridge

Environmental Modeller

My recent work has focused mainly on applications of biogeochemical modelling, including carbon cycling and storage in shelf seas, the effect of trawling on nutrient fluxes, and the interaction between nutrients, seaweeds, phytoplankton and shellfish aquaculture. I am also involved with the modelling of litter in UK coastal seas.

John is  a mathematical modeller with 30 year experience in modelling the marine environment. This has covered  both physical and biological processes and has  included the development and use of models of sediment and contaminant transport and biogeochemical processes. He has been involved in modelling the biogeochemistry of shelf seas using the ERSEM model as part of the  Defra/NERC Shelf Seas Biogeochemistry program, focusing on benthic processes and the effects of beam trawling. John has developed coupled models of phytoplankton and macroalgal growth for both natural and  farmed seaweed species to investigate the effect of changes in nutrient supply and the environmental  impact of farmed seaweeds. He has presented work at national and international conferences and been author on over 30 paper and articles with over 10 as first author. He is an editor for the journal Advances and Applications in Fluid Mechanics and a review editor for Frontiers in Marine Science (Global Change and the Future Ocean). John has acted as external supervisor for three Ph. D students. He has managed a number of Defra and Environment Agency projects, and lead the UK contribution to the EU funded EASYCO project.
