  • Unprecedented Beaufort Sea ice loss in late summer 2021 and its relationship to an extended period of unusually stormy weather

    Open AccessThomas J Ballinger, Peter M Finocchio et al.ARTICLEEnvironmental Research Letters2025

    Previous case studies have linked cyclone-induced atmospheric forcing and/or upper-ocean processes to notable Arctic sea ice loss events in the summers of 2012 and 2016. This study examines a more recent and noteworthy case in late summer 2021 in which substantial sea ice loss followed a period of surface meteorological extremes in the Beaufort Sea region of the Arctic. We focus on the period from mid-August to mid-September 2021 that coincided w…

  • The North Pole Region as an Indicator of the Changing Arctic Ocean

    Open AccessJames Morison, Jeremy Wilkinson et al.ARTICLEARCTIC2018

    Sustained observations of environmental conditions in the North Pole region are critical to understanding the changing Arctic Ocean. The Transpolar Drift conduit of sea ice and freshened upper-ocean waters across the Arctic Ocean passes over the North Pole region on its way to the North Atlantic through Fram and Nares Straits. The exported ice and freshened water stratifies the sub-Arctic seas and limits the vertical convection that ventilates th…

  • Stability of the arctic halocline

    Open AccessIgor V Polyakov, Andrey V Pnyushkov et al.ARTICLEEnvironmental Research Letters2018

    In this study, we propose a new Arctic climate change indicator based on the strength of the Arctic halocline, a porous barrier between the cold and fresh upper ocean and ice and the warm intermediate Atlantic Water of the Arctic Ocean. This indicator provides a measure of the vulnerability of sea ice to upward heat fluxes from the ocean interior, as well as the efficiency of mixing affecting carbon and nutrient exchanges. It utilizes the well-ac…

  • An observation-based assessment of the influences of air temperature and snow depth on soil temperature in Russia

    Open AccessHotaek Park, Artem B Sherstiukov et al.ARTICLEEnvironmental Research Letters2014

    This study assessed trends in the variability of soil temperature (T _SOIL ) using spatially averaged observation records from Russian meteorological land stations. The contributions of surface air temperature (SAT) and snow depth (SND) to T _SOIL variation were quantitatively evaluated. Composite time series of these data revealed positive trends during the period of 1921–2011, with accelerated increases since the 1970s. The T _SOIL warming rate…
