    • Circulation along the northern slope of the Greenland-Scotland Ridge 

      Semper, Stefanie (Doctoral thesis, 2020-12-11)
      The Greenland-Scotland Ridge separates the subpolar North Atlantic from the Nordic Seas and constrains the flow of the upper and lower branches of the northern extremity of the Atlantic Meridional Overturning Circulation ...

    • Coupled atmosphere–ocean observations of a cold-air outbreak and its impact on the Iceland Sea 

      Renfrew, Ian A.; Huang, Jie; Semper, Stefanie; Barrell, Christopher; Terpstra, Annick; Pickart, Robert S.; Våge, Kjetil; Elvidge, Andrew D.; Spengler, Thomas; Strehl, Anna-Marie; Weiss, Alexandra (Journal article; Peer reviewed, 2023)
      Marine cold-air outbreaks (CAOs) are vigorous equatorward excursions of cold air over the ocean, responsible for the majority of wintertime oceanic heat loss from the subpolar seas of the North Atlantic. However, the impact ...

    • 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 ...

    • How warm Gulf Stream water sustains a cold underwater waterfall 

      Semper, Stefanie; Glessmer, Mirjam Sophia; Våge, Kjetil; Pickart, Robert S. (Journal article, 2022)
      The most famous ocean current, the Gulf Stream, is part of a large system of currents that brings warm water from Florida to Europe. It is a main reason for northwestern Europe’s mild climate. What happens to the warm water ...

    • The Iceland Greenland seas project 

      Renfrew, Ian Alasdair; Pickart, RS; Våge, Kjetil; Moore, GWK; Bracegirdle, TJ; Elvidge, AD; Jeansson, Emil; Lachlan-Cope, T; McRaven, LT; Papritz, L; Reuder, Joachim; Sodemann, Harald; Terpstra, Annick; Waterman, S; Valdimarsson, H; Weiss, A; Almansi, M; Bahr, F; Brakstad, Ailin; Barrell, C; Brooke, JK; Brooks, BJ; Brooks, IM; Brooks, ME; Bruvik, Erik Magnus; Duscha, Christiane; Fer, Ilker; Golid, Heidi M.; Hallerstig, Matilda; Hessevik, Idar; Huang, J; Houghton, L; Jonsson, S; Jonassen, Marius Opsanger; Jackson, Kristin; Kvalsund, Karsten; Kolstad, Erik Wilhelm; Konstali, Kjersti; Kristiansen, Jørn; Ladkin, R; Lin, P; MacRander, A; Mitchell, A; Olafsson, H; Pacini, A; Payne, C; Palmason, B; Perez-Hernandez, MD; Peterson, Algot Kristoffer; Petersen, GN; Pisareva, MN; Pope, JO; Seidl, Andrew; Semper, Stefanie; Sergeev, D; Skjelsvik, Silje; Søiland, Henrik; Smith, D; Spall, MA; Spengler, Thomas; Touzeau, Alexandra; Tupper, G; Weng, Yongbiao; Williams, KD; Yang, X; Zhou, Shenjie (Peer reviewed; Journal article, 2019)
      The Iceland Greenland Seas Project (IGP) is a coordinated atmosphere–ocean research program investigating climate processes in the source region of the densest waters of the Atlantic meridional overturning circulation. ...

    • The Iceland-Faroe Slope Jet: a conduit for dense water toward the Faroe Bank Channel overflow 

      Semper, Stefanie; Pickart, Robert S.; Våge, Kjetil; Larsen, Karin Margretha H.; Hátún, Hjálmar; Hansen, Bogi (Journal article; Peer reviewed, 2020)
      Dense water from the Nordic Seas passes through the Faroe Bank Channel and supplies the lower limb of the Atlantic Meridional Overturning Circulation, a critical component of the climate system. Yet, the upstream pathways ...

    • Mechanisms of offshore solid and liquid freshwater flux from the East Greenland Current 

      Spall, Michael A.; Semper, Stefanie; Våge, Kjetil (Journal article; Peer reviewed, 2024)
      The mechanisms that control the export of freshwater from the East Greenland Current, in both liquid and solid form, are explored using an idealized numerical model and scaling theory. A regional, coupled ocean–sea ice ...

    • Seasonal resonance of diurnal coastal trapped waves in the southern Weddell Sea, Antarctica 

      Semper, Stefanie; Darelius, Elin Maria K. (Peer reviewed; Journal article, 2017-01-30)
      The summer enhancement of diurnal tidal currents at the shelf break in the southern Weddell Sea is studied using velocity measurements from 29 moorings during the period 1968 to 2014. Kinetic energy associated with diurnal ...

    • 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 ...
