PRINCIPAL INVESTIGATORS

United States of America

Duke University

  • 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.

National Oceanography Center

  • Sheldon Bacon – Sheldon is a Principal Investigator for UK-OSNAP and has overall responsibility for the project and linking with international partners.
  • Penny Holliday – Penny is leading the observations being made in the deep western boundary current near Greenland, and is Project Manager for UK-OSNAP.
  • Chris Wilson – Chris is leading the work to use Argo float data to make seasonal estimates of Subpolar Gyre circulation and mixing.

Scottish Association for Marine Sciences

  • 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.
  • Helen Johnson – Helen is examining Subpolar Gyre forcing anomalies and teleconnections. This 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.

Canada

Bedford Institute of Oceanography (DFO)

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 – (Northwest Atlantic Fisheries Centre, DFO) – 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.

China

Ocean University of China

  •  Dexing Wu – Dexing Wu is a Principal Investigator for China-OSNAP and responsible for the gliders that will measure volume, heat and salt flux in the eastern subpolar gyre.
  •  Xiaopei Lin – Xiaopei Lin is a Principal Investigator for China-OSNAP with overall responsibility for the Chinese contribution and for linkages with international partners.

Germany

IFM-GEOMAR

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).

Netherlands

Royal Netherlands Institute for Sea Research (NIOZ)

  • Laura de Steur – Laura is primarily responsible for the mooring array in the northward flowing Irminger Current on the Reykjanes Ridge in the Irminger Sea and interpretation of the data obtained by it. 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 will first be deployed in summer 2014 and will be serviced in 2015 and 2016 and 2018. In addition hydrographic measurements will be obtained during the yearly fieldwork providing near-synoptic high-resolution vertical profiles of temperature and salinity. Laura represents The Netherlands in the OSNAP steering committee.
