    • Arctic continental slopes sharp gradients of physical processes affect pelagic and benthic ecosystems. 

      Bluhm, Bodil; Janout, Markus; Danielson, Seth L.; Ellingsen, Ingrid H.; Gavrilo, Maria; Grebmeier, Jaqueline; Hopcroft, Russell R.; Iken, Katrin; Ingvaldsen, Randi Brunvær; Jørgensen, Lis Lindal; Kosobokova, Ksenia N.; Kwok, Ron; Polyakov, Igor V.; Renaud, Paul E.; Carmack, Eddy C. (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-11-20)
      Continental slopes – steep regions between the shelf break and abyssal ocean – play key roles in the climatology and ecology of the Arctic Ocean. Here, through review and synthesis, we find that the narrow slope regions contribute to ecosystem functioning disproportionately to the size of the habitat area (∼6% of total Arctic Ocean area). Driven by inflows of sub-Arctic waters and steered by topography, ...

    • Borealization of the Arctic Ocean in response to anomalous advection from sub-Arctic seas. 

      Polyakov, Igor V.; Alkire, Mattew; Bluhm, Bodil; Brown, Kristina; Carmack, Eddy C.; Chierici, Melissa; Danielson, Seth L.; Ellingsen, Ingrid H.; Ershova, Elizaveta; Gardfeldt, Katrin; Ingvaldsen, Randi Brunvær; Pnyushkov, Andrey V.; Slagstad, Dag; Wassmann, Paul (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-07-03)
      An important yet still not well documented aspect of recent changes in the Arctic Ocean is associated with the advection of anomalous sub-Arctic Atlantic- and Pacific-origin waters and biota into the polar basins, a process which we refer to as borealization. Using a 37-year archive of observations (1981–2017) we demonstrate dramatically contrasting regional responses to atlantification (that part ...

    • Freshwater and its role in the Arctic Marine System: Sources, disposition, storage, export, and physical and biogeochemical consequences in the Arctic and global oceans 

      Carmack, Eddy C.; Yamamoto-Kawai, Michiyo; Haine, Thomas W.N.; Bacon, Sheldon; Bluhm, Bodil; Lique, Camille; Melling, Humfrey; Polyakov, Igor V.; Straneo, Fiamma; Timmermans, Mary Louise E.; Williams, William J. (Journal article; Tidsskriftartikkel; Peer reviewed, 2015-10-11)
      The Arctic Ocean is a fundamental node in the global hydrological cycle and the ocean’s thermohaline circulation. We here assess the system’s key functions and processes: (1) the delivery of fresh and low-salinity waters to the Arctic Ocean by river inflow, net precipitation, distillation during the freeze/thaw cycle, and Pacific Ocean inflows; (2) the disposition (e.g., sources, pathways, and ...

    • New distribution records of kelp in the Kitikmeot Region, Northwest Passage, Canada, fill a pan-Arctic gap 

      Bluhm, Bodil; Brown, Kristina; Rotermund, Lina; Williams, William; Danielsen, Seth; Carmack, Eddy C. (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-03-01)
      Kelps play important roles in ecosystems as they provide structural habitat and protection, and supply food. Given these beneficial roles and observed increases in seaweed biomass and distribution ranges across the Arctic, mapping kelp occurrence around Arctic coasts is both timely and necessary for future conservation. Here, we fill spatial gaps in the knowledge of kelp distribution in the southern ...
