Current activities

OFRD has the responsibility for developing models and satellite analyses for short-range ocean monitoring and forecasting, and is also involved in producing reanalyses for monitoring marine environment.

The group develop systems to provide the Met Office's monitoring and prediction capability for surface waves, storm surges, ocean dynamics and biogeochemistry forecast as well as the OSTIA sea ice and sea surface temperature satellite based analysis. This includes the responsibility for developing the waves modelling and marine data assimilation capability that is also used more widely in the Met Office.

Research on developing coupled atmosphere-wave-ocean-ice-biogeochemistry systems is being lead from the OFRD group, with the aim of developing a regional and global coupled systems for Numerical Weather Prediction, Ocean Forecasting and Environmental Prediction.

Career background

John had science leadership roles in the Ocean Forecasting Research and Development area from 2007 until 2012, when he became lead of the Ocean Modelling Group, providing ocean model development based on NEMO for applications across the Met Office. He became Head of Ocean Forecasting in 2014.

Prior to taking on management responsibilities John worked as Coastal Ocean Modelling Scientist (July 2003 to May 2007), with responsibilities for preparing developments to the suite of marine models run for the North West European shelf. John implemented, tested and transitioned to operations the ecosystem component  of the MRCS North-West Shelf model and had primary responsibility for the research and development, monitoring and maintenance of the ocean shelf ecosystem and sediment short-term forecasting systems.

Prior to his career at the Met Office John worked for the Natural Environmental Research Council at Plymouth Marine Laboratory as a mathematical modeller in a biogeochemistry modelling team with the primary responsibility for implementing marine dynamical models and coupling them to ERSEM.

John was awarded his PhD by published works from Bangor University School of Ocean Sciences in 2016. He previously studied for an MSc in Applied Physical Oceanography (1997/8) at Bangor, where he was awarded the Darbyshire prize. He obtained his undergraduate degree in Marine Environmental Chemistry at the University of Southampton (1991-1994).
