UK-OSNAP is a collaboration across many centres in the UK. The researchers 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.

UK-OSNAP is a programme supported by a series of NERC grants since 2013:

UK-OSNAP Large Grant (2013-2018)

UK-OSNAP Extension (2018-2019)

UK-OSNAP Decade (2019-2023)

SNAP-DRAGON (2020-2023)

UK-OSNAP Extension (2023-2024)


People active in UK OSNAP now:

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).

Dr Loïc Houpert (NOC) is the lead researcher for the Iceland Basins now operated by NOC

Darren Rayner (NOC) is the lead technical developer for UKOSNAP moorings.

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 researchers Sam Jones, Neill Fraser and Clare Johnson (SAMS).

Prof David Marshall (University of Oxford) co-Investigator for UK-OSNAP and SNAP-DRAGON, examining Subpolar Gyre forcing anomalies and teleconnections.

Dr Helen Johnson (University of Oxford) co-Investigator for UK-OSNAP and PI for SNAP-DRAGON. 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

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.


Previously part of UK OSNAP:

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

Dr Chris Wilson (NOC) led work under the first grant to use profile and air-sea fluxes data to make estimates of Subpolar Gyre circulation and mixing.

Neil Mackay was a NOC postdoc working with Chris Wilson

Yavor Kostov was a postdoc at University of Oxford working with David Marshall and Helen Johnson
