    • 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 ...

    • Eddies and the Distribution of Eddy Kinetic Energy in the Arctic Ocean 

      von Appen, Wilken-Jon; Baumann, Till Martin; Janout, Markus; Koldunov, Nicolay; Lenn, Yueng-Djern; Pickart, R.S.; Scott, Robert B.; Wang, Qiang (Journal article; Peer reviewed, 2022)
      Mesoscale eddies are important to many aspects of the dynamics of the Arctic Ocean. Among others, they maintain the halocline and interact with the Atlantic Water circumpolar boundary current through lateral eddy fluxes ...

    • 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, ...

    • Overview of the MOSAiC expedition: Physical oceanography 

      Rabe, Benjamin; Baumann, Till Martin; Divine, Dmitry; Fer, Ilker; Gradinger, Rolf Rudolf; Granskog, Mats; Koenig, Zoe Charlotte; Muilwijk, Morven; Sundfjord, Arild (Journal article; Peer reviewed, 2022)
      Arctic Ocean properties and processes are highly relevant to the regional and global coupled climate system, yet still scarcely observed, especially in winter. Team OCEAN conducted a full year of physical oceanography ...

    • A Steady Regime of Volume and Heat Transports in the Eastern Arctic Ocean in the Early 21st Century 

      Pnyushkov, A.V.; Polyakov, Igor V.; Alekseev, G.V.; Ashik, I.M.; Baumann, Till Martin; Carmack, E.; Ivanov, Vladimir; Rember, Robert (Journal article; Peer reviewed, 2021)
      Mooring observations in the eastern Eurasian Basin of the Arctic Ocean showed that mean 2013–2018 along-slope volume and heat (calculated relative to the freezing temperature) transports in the upper 800 m were 4.8 ± 0.1 ...

    • Trapped tidal currents generate freely propagating internal waves at the Arctic continental slope 

      Baumann, Till Martin; Fer, Ilker (Journal article; Peer reviewed, 2023)
      Energetic tidal currents in the Arctic play an important role in local mixing processes, but they are primarily confined to the shelves and continental slopes due to topographic trapping north of their critical latitude. ...

    • Upper-ocean turbulence structure and ocean-ice drag coefficient estimates using an ascending microstructure profiler during the MOSAiC drift 

      Fer, Ilker; Baumann, Till Martin; Koenig, Zoe Charlotte; Muilwijk, Morven; Tippenhauer, Sandra (Journal article; Peer reviewed, 2022)
      Sea ice mediates the transfer of momentum, heat, and gas between the atmosphere and ocean. However, the under-ice boundary layer is not sufficiently constrained by observations. During the Multidisciplinary drifting ...
