• 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), ...
    • Characteristics and Transformation of Pacific Winter Water on the Chukchi Sea Shelf in Late Spring 

      Pacini, Astrid; Moore, George William Kent; Pickart, Robert S.; Nobre, Carolina; Bahr, Frank; Våge, Kjetil; Arrigo, Kevin R. (Peer reviewed; Journal article, 2019)
      Data from a late spring survey of the northeast Chukchi Sea are used to investigate various aspects of newly ventilated winter water (NVWW). More than 96% of the water sampled on the shelf was NVWW, the saltiest (densest) ...
    • Large decadal changes in air-sea CO2 fluxes in the Caribbean Sea 

      Wanninkhof, Rik; Triñanes, Joaquin A; Park, Guen-Ha; Gledhill, Dwight K.; Olsen, Are Christian Sviggum (Peer reviewed; Journal article, 2019)
      Sixteen years of surface water CO2 data from autonomous systems on cruise ships sailing in the Caribbean Sea and Western North Atlantic show marked changes on interannual timescales. The measured changes in fugacity (≈partial ...
    • Lateral Heat Transport in the Lofoten Basin: Near-Surface Pathways and Subsurface Exchange 

      Dugstad, Johannes Sandanger; Fer, Ilker; Lacasce, Joseph Henry; Sanchez de la Lama, Marta; Trodahl, Marta (Peer reviewed; Journal article, 2019)
      The Lofoten Basin in the Nordic Seas plays a central role in the Atlantic overturning circulation by acting as a reservoir for the warm and saline Atlantic Water flow toward the Arctic Ocean. The mass and heat exchange ...
    • Observations of Turbulence at a Near-Surface Temperature Front in the Arctic Ocean 

      Koenig, Zoé Charlotte; Fer, Ilker; Kolås, Eivind; Fossum, Trygve Olav; Norgren, Petter; Ludvigsen, Martin (Journal article; Peer reviewed, 2020)
      High-resolution ocean temperature, salinity, current, and turbulence data were collected at an Arctic thermohaline front in the Nansen Basin. The front was close to the sea ice edge and separated the cold and fresh surface ...
    • Pathways and Water Mass Transformation Along and Across the Mohn‐Knipovich Ridge in the Nordic Seas 

      Ypma, Stefanie; Georgiou, S.; Dugstad, Johannes Sandanger; Pietrzak, J.D.; Katsman, C.A. (Journal article; Peer reviewed, 2020)
      Atlantic Water takes various pathways through the Nordic Seas, and its transformation to denser waters forms a crucial connection to the lower limb of the Atlantic Meridional Overturning Circulation. Circulation maps often ...
    • A Satellite Era Warming Hole in the Equatorial Atlantic Ocean 

      Nnamchi, Hyacinth C; Latif, Mojib; Keenlyside, Noel; Park, Wonsun (Journal article; Peer reviewed, 2020)
      Observations during the satellite era 1979–2018 only depict small sea surface temperature (SST) trends over the Equatorial Atlantic cold tongue region in boreal summer. This lack of surface warming of the cold tongue, ...
    • Structure and Transport of Atlantic Water North of Svalbard From Observations in Summer and Fall 2018 

      Kolås, Eivind; Koenig, Zoé Charlotte; Fer, Ilker; Nilsen, Frank; Marnela, Marika (Journal article; Peer reviewed, 2020)
      The transport of warm Atlantic Waters north of Svalbard is one of the major heat and salt sources to the Arctic Ocean. The circulation pathways and the associated heat transport influence the variability in the Arctic sea ...
    • Vertical structure and seasonal variability of the inflow to the Lofoten Basin inferred from high resolution Lagrangian simulations 

      Dugstad, Johannes Sandanger; Kozalka, Inga Monika; Isachsen, Pål Erik; Dagestad, Knut-Frode; Fer, Ilker (Peer reviewed; Journal article, 2019-11-13)
      The Lofoten Basin in the eastern Nordic Seas plays a central role in modifying the warm Atlantic Water inflow toward the Arctic Ocean. Here, the Atlantic Water experiences increased residence times, cooling, and substantial ...
    • Warm Atlantic water explains observed sea ice melt rates north of Svalbard 

      Duarte, Pedro; Sundfjord, Arild; Meyer, Amelie; Hudson, Stephen; Spreen, Gunnar; Smedsrud, Lars Henrik (Journal article; Peer reviewed, 2020)
      Warm Atlantic water (AW) that flows northward along the Svalbard west coast is thought to transport enough heat to melt regional Arctic sea ice effectively. Despite this common assumption, quantitative requirements necessary ...
