    • Along‐stream, seasonal, and interannual variability of the North Icelandic Irminger Current and East Icelandic Current around Iceland 

      Casanova-Masjoan, M; Perez-Hernandez, MD; Pickart, Robert S.; Valdimarsson, Héðinn; Ólafsdóttir, SR; Macrander, Andreas; Grisolía-Santos, D; Torres, Daniel J.; Jónsson, Steingrímur; Våge, Kjetil; Lin, Peigen; Hernández-Guerra, A (Journal article; Peer reviewed, 2020)
      Data from repeat hydrographic surveys over the 25-year period 1993 to 2017, together with satellite altimetry data, are used to quantify the temporal and spatial variability of the North Icelandic Irminger Current (NIIC), ...

    • Attuning to a changing ocean 

      Stenseth, Nils Christian; Payne, Mark R.; Bonsdorff, Erik; Dankel, Dorothy Jane; Durant, Joel Marcel; Anderson, Leif G.; Armstrong, Claire W.; Blenckner, Thorsten; Brakstad, Ailin; Dupont, Sam; Eikeset, Anne Maria; Goksøyr, Anders; Jónsson, Steingrímur; Kuparinen, Anna; Våge, Kjetil; Österblom, Henrik; Paasche, Øyvind (Journal article; Peer reviewed, 2020)
      The ocean is a lifeline for human existence, but current practices risk severely undermining ocean sustainability. Present and future social−ecological challenges necessitate the maintenance and development of knowledge ...

    • The Emergence of the North Icelandic Jet and Its Evolution from Northeast Iceland to Denmark Strait 

      Semper, Stefanie; Våge, Kjetil; Pickart, Robert S.; Valdimarsson, Hedinn; Torres, Daniel J.; Jónsson, Steingrímur (Peer reviewed; Journal article, 2019)
      The North Icelandic Jet (NIJ) is an important source of dense water to the overflow plume passing through Denmark Strait. The properties, structure, and transport of the NIJ are investigated for the first time along its ...

    • Evolution and Transformation of the North Icelandic Irminger Current Along the North Iceland Shelf 

      Semper, Stefanie; Våge, Kjetil; Pickart, Robert S.; Jónsson, Steingrímur; Valdimarsson, Hedinn (Journal article; Peer reviewed, 2022)
      The North Icelandic Irminger Current (NIIC) flowing northward through Denmark Strait is the main source of salt and heat to the north Iceland shelf. We quantify its along-stream evolution using the first high-resolution ...

    • Measured volume, heat, and salt fluxes from the Atlantic to the Arctic Mediterranean 

      Østerhus, Svein; Turrell, William R.; Jónsson, Steingrímur; Hansen, Bogi (Journal article, 2005-04-07)
      The flow of warm and saline Atlantic water towards the Arctic crosses the Greenland-Scotland Ridge in three current branches. Since the mid 1990's, extensive monitoring with quasi-permanent moorings and regular CTD cruises ...

    • Upstream sources of the Denmark Strait Overflow: Observations from a high-resolution mooring array 

      Harden, Benjamin E.; Pickart, Robert S.; Valdimarsson, Héðinn; Våge, Kjetil; de Steur, Laura; Richards, Clark; Bahr, Frank; Torres, Dan; Børve, Eli; Jónsson, Steingrímur; Macrander, Andreas; Østerhus, Svein; Håvik, Lisbeth; Hattermann, Tore (Peer reviewed; Journal article, 2016)
      We present the first results from a densely instrumented mooring array upstream of the Denmark Strait sill, extending from the Iceland shelfbreak to the Greenland shelf. The array was deployed from September 2011 to July ...

    • Water mass transformation in the Iceland Sea 

      Våge, Kjetil; Moore, George William Kent; Jónsson, Steingrímur; Valdimarsson, Héðinn (Peer reviewed; Journal article, 2015)
      The water mass transformation that takes place in the Iceland Sea during winter is investigated using historical hydrographic data and atmospheric reanalysis fields. Surface densities exceeding σθ ¼ 27:8 kg=m3, and hence ...

    • Water mass transformation in the Iceland Sea: Contrasting two winters separated by four decades 

      Våge, Kjetil; Semper, Stefanie; Valdimarsson, Héðinn; Jónsson, Steingrímur; Pickart, Robert S.; Moore, G.W.K. (Journal article; Peer reviewed, 2022)
      Dense water masses formed in the Nordic Seas flow across the Greenland–Scotland Ridge and contribute substantially to the lower limb of the Atlantic Meridional Overturning Circulation. Originally considered an important ...
