    • Microbial activity, methane production, and carbon storage in Early Holocene North Sea peats 

      Lippmann, Tanya J. R.; 't Zandt, Michiel H. in; Van der Putten, Nathalie N. L.; Busschers, Freek S.; Hijma, Marc P.; van der Velden, Pieter; de Groot, Tim; van Aalderen, Zicarlo; Meisel, Ove H.; Slomp, Caroline P.; Niemann, Helge; Jetten, Mike S. M.; Dolman, Han A. J.; Welte, Cornelia U. (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-10-11)
      <p>Northern latitude peatlands act as important carbon sources and sinks, but little is known about the greenhouse gas (GHG) budgets of peatlands that were submerged beneath the North Sea during the last glacial–interglacial transition. <p>We found that whilst peat formation was diachronous, commencing between 13 680 and 8360 calibrated years before the present, stratigraphic layering and local ...

    • Plastic photodegradation under simulated marine conditions 

      Delre, Annalisa; Goudriaan, Maaike; Morales, Victor Hernando; Vaksmaa, Annika; Rachel Tintswalo, Ndhlovu; Marianne, Baas; Keijzer, Edwin; de Groot, Tim; Zeghal, Emna; Egger, Matthias; Röckmann, Thomas; Niemann, Helge (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-01-12)
      Ocean plastic pollution is a problem of increasing magnitude; yet, the amount of plastic at the sea surface is much lower than expected. Solar ultraviolet (UV) radiation can induce photodegradation, but its importance in determining the longevity of floating plastic remains unconstrained. Here, we measured photodegradation rates of different plastic types slightly larger than microplastics (virgin ...
