    • Dissolved, Labile, and Total Particulate Trace Metal Dynamics on the Northeast Greenland Shelf 

      Chen, Xue‐Gang; Krisch, StephanORCIDiD; Al‐Hashem, AliORCIDiD; Hopwood, Mark James; Rutgers van der Loeff, Michiel M.ORCIDiD; Huhn, OliverORCIDiD; Lodeiro, PabloORCIDiD; Steffens, Tim; Achterberg, Eric P.ORCIDiD (Global Biogeochemical Cycles, 2022-11-28)
      We present high‐resolution profiles of dissolved, labile, and total particulate trace metals (TMs) on the Northeast Greenland shelf from GEOTRACES cruise GN05 in August 2016. Combined with radium isotopes, stable oxygen ...

    • Near-Complete Local Reduction of Arctic Stratospheric Ozone by Severe Chemical Loss in Spring 2020 

      Wohltmann, I.ORCIDiD; von der Gathen, P.ORCIDiD; Lehmann, R.; Maturilli, M.ORCIDiD; Deckelmann, H.ORCIDiD; Manney, G. L.ORCIDiD; Davies, J.; Tarasick, D.ORCIDiD; Jepsen, N.; Kivi, R.ORCIDiD; Lyall, N.; Rex, M. (Geophysical Research Letters, 2020)
      In the Antarctic ozone hole, ozone mixing ratios have been decreasing to extremely low values of 0.01–0.1 ppm in nearly all spring seasons since the late 1980s, corresponding to 95–99% local chemical loss. In contrast, ...

    • Quantifying Ice‐Sheet Derived Lead (Pb) Fluxes to the Ocean; A Case Study at Nioghalvfjerdsbræ 

      Krisch, StephanORCIDiD; Huhn, OliverORCIDiD; Al‐Hashem, AliORCIDiD; Hopwood, Mark J.ORCIDiD; Lodeiro, PabloORCIDiD; Achterberg, Eric P.ORCIDiD (Geophysical Research Letters, 2022-11-07)
      Concentrations of the toxic element lead (Pb) are elevated in seawater due to historical emissions. While anthropogenic atmospheric emissions are the dominant source of dissolved Pb (dPb) to the Atlantic Ocean, evidence ...
