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.

Prof 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 led the observations made in the deep western boundary current near Greenland (analysed by Jo Hopkins, NOC) and is now leading the deployment of UKOSNAP moorings in the Iceland Basin. Darren Rayner (NOC) is the lead technical developer for UKOSNAP moorings.

Prof Sheldon Bacon (NOC) was the original Principal Investigator for UK-OSNAP.

Dr Chris Wilson (NOC) led work to use profile and air-sea fluxes data to make 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. 

Prof 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 postdocs Loic Houpert (NOC), Sam Jones, Neill Fraser and Clare Johnson (SAMS).

Prof David Marshall (University of Oxford) was Principal Investigator examining Subpolar Gyre forcing anomalies and teleconnections. With Dr Helen Johnson, the analysis made use of adjoint modelling and theoretical analysis to identify the teleconnections between forcing anomalies and the strength and structure of the Subpolar Gyre. They were working with UK-OSNAP Postdoc Yavor Kostov who is now at University of Exeter

Prof. Ric Williams (University of Liverpool) was Principal Investigator leading analysis of how ocean heat storage in the Subpolar Gyre varies over time using a combination of data assimilation and forward model integrations to look at how changes in surface fluxes affect heat storage and heat transport. He was working with Dr Vassil Roussenov.
