UK-OSNAP is a collaboration across many centres in the UK. The investigators listed below are the leaders of the programme and we work with many other scientists, engineers and technicians to make the ocean observations and run models. We work closely with a range of people and organisations who will benefit from the results and new understanding that come from the programme.
Dr Penny Holliday (NOC) is the present PI for UK-OSNAP, with overall responsibility for the project and linking with our international partners (international OSNAP). She also leads the observations being made in the deep western boundary current near Greenland.
Dr Sheldon Bacon (NOC) was the original Principal Investigator for UK-OSNAP.
Dr Chris Wilson (NOC) is leading the work to use Argo float data to make seasonal estimates of Subpolar Gyre circulation and mixing. From 2014-2018 Chris worked with UK-OSNAP postdoc, Neil Mackay who is now working at University of Exeter.
Dr Stuart Cunningham and Prof. Mark Inall (SAMS) are leading the observations of the eastern part of the monitoring array, with innovative use of moorings and gliders to measure volume, heat and salt flux in the eastern gyre. They are working with UK-OSNAP postdoc Loic Houpert.
Prof David Marshall (University of Oxford) is Principal Investigator examining Subpolar Gyre forcing anomalies and teleconnections. With Dr Helen Johnson, the analysis will make use of adjoint modelling and theoretical analysis to identify the teleconnections between forcing anomalies and the strength and structure of the Subpolar Gyre. They are working with UK-OSNAP Postdoc Yavor Kostov.
Prof. Ric Williams (University of Liverpool) is Principal Investigator leading analysis of how ocean heat storage in the Subpolar Gyre varies over time. The analysis will use a combination of data assimilation and forward model integrations look at how changes in surface fluxes affect heat storage and heat transport. He is working with Dr Vassil Roussenov.
Elizabeth Comer started her PhD at NOC in October 2014. She is working on subpolar gyre dynamics and the variability of the region using Extended Ellett Line and OSNAP data with supervisors Holliday, Bacon, Cunningham and Haig.
