• Arctic tidal current atlas 

      Baumann, Till Martin; Polyakov, Igor V.; Padman, Laurie; Danielson, Seth L.; Fer, Ilker; Janout, Markus; Williams, William; Pnyushkov, Andrey V. (Journal article; Peer reviewed, 2020)
      Tidal and wind-driven near-inertial currents play a vital role in the changing Arctic climate and the marine ecosystems. We compiled 429 available moored current observations taken over the last two decades throughout the ...
    • Intensification of Near‐Surface Currents and Shear in the Eastern Arctic Ocean 

      Polyakov, Igor V.; Rippeth, Tom; Fer, Ilker; Baumann, Till Martin; Carmack, Eddy C.; Ivanov, Vladimir V.; Janout, Markus; Padman, Laurie; Pnyushkov, A.V.; Rember, Robert (Journal article; Peer reviewed, 2020)
      A 15‐year (2004–2018) record of mooring observations from the upper 50 m of the ocean in the eastern Eurasian Basin reveals increased current speeds and vertical shear, associated with an increasing coupling between wind, ...
    • One more step toward a warmer Arctic 

      Polyakov, Igor V.; Beszczynska-Möller, Agnieszka; Carmack, Eddy C.; Dmitreko, Igor A.; Fahrbach, E.; Frolov, Ivan E.; Gerdes, Rüdiger; Hansen, Edmond; Holfort, Jürgen; Ivanov, Vladimir V.; Johnson, Mark A.; Karcher, Michael; Kauker, Frank; Morison, James; Orvik, Kjell Arild; Schauer, Ursula; Simmons, Harper L.; Skagseth, Øystein; Sokolov, Vladimir T.; Steele, Michael; Timokhov, Leonid A.; Walsh, David; Walsh, John E. (Peer reviewed; Journal article, 2005-09-09)
      This study was motivated by a strong warming signal seen in mooring-based and oceanographic survey data collected in 2004 in the Eurasian Basin of the Arctic Ocean. The source of this and earlier Arctic Ocean changes lies ...
    • Towards quantifying the increasing role of oceanic heat in sea ice loss in the new Arctic 

      Carmack, Eddy; Polyakov, Igor V.; Padman, Laurie; Fer, Ilker; Hunke, Elizabeth Clare; Hutchings, Jennifer J.; Jackson, Jennifer M.; Kelley, Daǹ E.; Kwok, Ronald; Layton, Chantelle; Melling, Humfrey; Perovich, Donald K.; Persson, Ola G.; Ruddick, Barry; Timmermans, Mary Louise E.; Toole, John M.; Ross, Tetjana; Vavrus, Steve J.; Winsor, Peter R. (Peer reviewed; Journal article, 2015)
      The loss of Arctic sea ice has emerged as a leading signal of global warming. This, together with acknowledged impacts on other components of the Earth system, has led to the term “the new Arctic.” Global coupled climate ...
    • Vertical structure of recent arctic warming from observed data and reanalysis products 

      Alexeev, V. A.; Esau, Igor N.; Polyakov, Igor V.; Byam, S. J.; Sorokina, Svetlana (Peer reviewed; Journal article, 2012-03)
      Spatiotemporal patterns of recent (1979–2008) air temperature trends are evaluated using three reanalysis datasets and radiosonde data. Our analysis demonstrates large discrepancies between the reanalysis datasets, possibly ...
    • Weakening of Cold Halocline Layer Exposes Sea Ice to Oceanic Heat in the Eastern Arctic Ocean 

      Polyakov, Igor V.; Rippeth, Tom; Fer, Ilker; Alkire, Matthew B.; Carmack, Eddy; Ingvaldsen, Randi Brunvær; Ivanov, Vladimir V.; Janout, Markus; Lind, Sigrid; Padman, Laurie; Pnyushkov, Andrey V.; Rember, Robert (Journal article; Peer reviewed, 2020)
      A 15-yr duration record of mooring observations from the eastern (>70°E) Eurasian Basin (EB) of the Arctic Ocean is used to show and quantify the recently increased oceanic heat flux from intermediate-depth (~150–900 m) ...
