    • Arctic sea-ice loss fuels extreme European snowfall 

      Bailey, Hannah L.; Hubbard, Alun Lloyd; Klein, Eric S.; Mustonen, Kaisa-Riikka; Akers, Pete D.; Marttila, Hannu; Welker, Jeffrey M. (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-04-01)
      The loss of Arctic sea-ice has been implicated with severe cold and snowy mid-latitude winters. However, the mechanisms and a direct link remain elusive due to limited observational evidence. Here we present atmospheric water vapour isotope measurements from Arctic Finland during ‘the Beast from the East’—a severe anticyclonic outbreak that brought heavy snowfall and freezing across Europe in February ...

    • Extraordinary runoff from the Greenland ice sheet in 2012 amplified by hypsometry and depleted firn retention 

      Mikkelsen, A.B.; Hubbard, Alun Lloyd; MacFerrin, Mike; Box, Jason Eric; Doyle, Sam H.; Fitzpatrick, Andrew; Hasholt, Bent; Bailey, Hannah L.; Lindbäck, Katrin; Pettersson, Rickard (Journal article; Tidsskriftartikkel; Peer reviewed, 2016-05-30)
      It has been argued that the infiltration and retention of meltwater within firn across the percolation zone of the Greenland ice sheet has the potential to buffer up to  ∼  3.6 mm of global sea-level rise (Harper et al., 2012). Despite evidence confirming active refreezing processes above the equilibrium line, their impact on runoff and proglacial discharge has yet to be assessed. Here, we compare ...

    • Holocene atmospheric circulation in the central North Pacific: A new terrestrial diatom and d18O dataset from the Aleutian Islands 

      Bailey, Hannah L.; Kaufman, Darrell S.; Sloane, Hilary J.; Hubbard, Alun Lloyd; Henderson, Andrew C.G.; Leng, Melanie J.; Meyer, Hanno; Welker, Jeffrey M. (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-07-02)
      The North Pacific is a zone of cyclogenesis that modulates synoptic-scale atmospheric circulation, yet there is a paucity of instrumental and paleoclimate data to fully constrain its long-term state and variability. We present the first Holocene oxygen isotope record (δ<sup>18</sup>O<sub>diatom</sub>) from the Aleutian Islands, using siliceous diatoms preserved in Heart Lake on Adak Island (51.85° ...
