    • 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 ...

    • Formation and pathways of dense water in the Nordic Seas 

      Brakstad, Ailin (Doctoral thesis, 2023-10-20)
      Sammendrag De nordiske hav er viktig for dannelsen av kalde, tette og dype vannmasser som strømmer sørover på tvers av Grønland-Skottland-ryggen og forsyner den dype grenen av omveltningssirkulasjonen i Atlanterhavet. På ...

    • How Is the Ocean Anthropogenic Carbon Reservoir Filled? 

      Davila, Xabier; Gebbie, Geoffrey; Brakstad, Ailin; Lauvset, Siv Kari; McDonagh, Elaine Louise; Schwinger, Jörg; Olsen, Are (Journal article; Peer reviewed, 2022)
      About a quarter of the total anthropogenic CO2 emissions during the industrial era has been absorbed by the ocean. The rate limiting step for this uptake is the transport of the anthropogenic carbon (Cant) from the ocean ...

    • 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 Impact of Cold-Air Outbreaks and Oceanic Lateral Fluxes on Dense-Water Formation in the Greenland Sea from a 10-Year Moored Record (1999–2009) 

      Svingen, Kristin; Brakstad, Ailin; Våge, Kjetil; Von Appen, Wilken-Jon; Papritz, Lukas (Journal article; Peer reviewed, 2023)
      The Greenland Sea produces a significant portion of the dense water from the Nordic seas that supplies the lower limb of the Atlantic meridional overturning circulation. Here, we use a continuous 10-yr hydrographic record ...

    • Nordic Seas Heat Loss, Atlantic Inflow, and Arctic Sea Ice cover over the last century 

      Smedsrud, Lars Henrik; Muilwijk, Morven; Eldevik, Tor; Årthun, Marius; Brakstad, Ailin; Madonna, Erica; Lauvset, Siv Kari; Spensberger, Clemens; Born, Andreas; Drange, Helge; Jeansson, Emil; Li, Camille; Olsen, Are; Skagseth, Øystein; Slater, Donald; Straneo, Fiammetta; Våge, Kjetil (Journal article; Peer reviewed, 2021)
      Poleward ocean heat transport is a key process in the earth system. We detail and review the northward Atlantic Water (AW) flow, Arctic Ocean heat transport, and heat loss to the atmosphere since 1900 in relation to sea ...

    • On the Origins of Open Ocean Oxygen Minimum Zones 

      Davila, Xabier; Olsen, Are; Lauvset, Siv Kari; McDonagh, Elaine Louise; Brakstad, Ailin; Gebbie, Geoffrey (Journal article; Peer reviewed, 2023)
      Recent work suggests that Oxygen Minimum Zones (OMZs) are sustained by the supply of oxygen-poor waters rather than the export of organic matter from the local surface layer and its subsequent remineralization inside OMZs. ...

    • Sources and upstream pathways of the densest overflow water in the Nordic Seas 

      Huang, Jie; Pickart, Robert S.; Huang, Rui Xin; Lin, Peigen; Brakstad, Ailin; Xu, Fanghua (Journal article; Peer reviewed, 2020)
      Overflow water from the Nordic Seas comprises the deepest limb of the Atlantic Meridional Overturning Circulation, yet questions remain as to where it is ventilated and how it reaches the Greenland-Scotland Ridge. Here we ...

    • Transient Increase in Arctic Deep-Water Formation and Ocean Circulation under Sea Ice Retreat 

      Bretones, Anais Magali; Nisancioglu, Kerim Hestnes; Jensen, Mari Fjalstad; Brakstad, Ailin; Yang, Shuting (Journal article; Peer reviewed, 2021)
      While a rapid sea ice retreat in the Arctic has become ubiquitous, the potential weakening of the Atlantic meridional overturning circulation (AMOC) in response to global warming is still under debate. As deep mixing occurs ...
