Susan Lozier – Susan has responsibility for the coordination of international and national projects associated with OSNAP. As such, she has responsibility for integrating the measurements of OSNAP East and West to produce a continuous record of the North Atlantic subploar AMOC, the overall goal of this international effort. She is also partnering with Amy Bower for the OSNAP Floats program, an effort designed to trace the pathways of overflow waters in the basin and to assess the connectivity of currents crossing the OSNAP line. Finally, Susan is responsible for program communication to international and U.S. OSNAP collaborators, the project website and the web-accessible OSNAP database maintained at Duke University.
Feili Li – Feili a Co-PI for US OSNAP, and is leading the working groups on various issues related to data management, analysis, as well as array optimization. He has been involved in project coordination and management.

- Stuart Cunningham – Stuart is co-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.
- Mark Inall – Mark is co-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.
University of Oxford
- David Marshall – David is a 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.

University of Liverpool
- Ric Williams – Ric is a 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 will be working with Dr Vassil Roussenov.

Memorial University of Newfoundland
- Brad de Young – Brad is the Canadian representative on the OSNAP steering committee. He works in partnership with Blair Greenan and Guoqi Han to coordinate the Canadian contribution to OSNAP on the Labrador Slope. He is also an investigator with the Vitals program in the Labrador Sea, deploying moorings in the Labrador Sea in 2015/16 and gliders there on the Labrador Shelf from 2014-2016.
Northwest Atlantic Fisheries Centre (DFO)
- Guoqi Han – Guoqi is responsible for deployment of moorings inshore of the OSNAP shelf-break array at 53N on the Labrador Slope. He works in partnership with Blair Greenan and Brad deYoung to coordinate the Canadian contribution to OSNAP.
University of Alberta
- Paul Myers – Paul is the lead for the Canadian VITALS Programs which will complement work done through OSNAP in the Labrador Sea. This project will involve a profiling SeaCycler mooring for biogeochemistry in the central Labrador Sea, as well as glider and floats work around the mooring, as well as along the offshore edge of the Labrador Current. He is also responsible for integrating these observations with high resolution pan-Arctic numerical modelling. This modelling is also linked with Geotraces and ASOF related studies examining Arctic-Atlantic linkages. He is also a PI in NAVIS.

The GEOMAR group, Johannes Karstensen, Jürgen Fischer and Martin Visbeck are international contributors to OSNAP primarily via a mooring array (53°N array) that is located at the southern exit of the Labrador Sea, where the OSNAP west section intersects with the Labrador Shelf.
The array is configured to measure transport and properties of the Deep Western Boundary Current in different water mass classes. Installed in 1997, it is maintained from Kiel since then (now by the GEOMAR Helmholtz Centre for Ocean Research Kiel, in Kiel, Germany).
The GEOMAR group will further contribute to the larger scale hydrography and add their expertise on direct current observations (LADCP measurements).
The group is also involved in the European Union “North Atlantic Climate” (NACLIM) project (www.naclim.eu) in the Workpackage on transports in the Subpolar North Atlantic (WP2.2).
Royal Netherlands Institute for Sea Research (NIOZ)
- Femke de Jong (NIOZ) – Femke currently coordinates the OSNAP moorings in the Irminger Current and represents the Netherlands in the OSNAP steering committee.
- Laura de Steur (NPI/NIOZ) – Laura led the Dutch component in OSNAP between 2014-2017.
The mooring array in the northward flowing Irminger Current on the western Reykjanes Ridge in the Irminger Sea has been installed and maintained by NIOZ. The array consists of four tall moorings measuring the velocity, temperature and salinity of the Irminger Current. This data will provide volume and heat transport in this branch of the AMOC and the variability therein. The array was first deployed in summer 2014 and has been serviced in 2015, 2016, and 2018. In addition, hydrographic measurements have been obtained during the (bi)annual fieldwork providing near-synoptic high-resolution vertical profiles of temperature and salinity. The NIOZ moorings will be serviced again and redeployed for the 2020-2022 period.
