    • Detection of ice core particles via deep neural networks 

      Maffezzoli, Niccolò; Cook, Eliza; van der Bilt, Willem Godert Maria; Støren, Eivind; Festi, Daniela; Muthreich, Florian; Seddon, Alistair William Robin; Burgay, François; Baccolo, Giovanni; Mygind, Amalie; Petersen, Troels; Spolaor, Andrea; Vascon, Alessio; Pelillo, Marcello; Ferretti, Patrizia; dos Reis, Rafael S.; Simões, Jefferson; Ronen, Yuval; Delmonte, Barbara; Viccaro, Marco; Steffensen, Jørgen Peder; Dahl-Jensen, Dorthe; Nisancioglu, Kerim Hestnes; Brabante, Carlo (Journal article; Peer reviewed, 2023)
      Insoluble particles in ice cores record signatures of past climate parameters like vegetation dynamics, volcanic activity, and aridity. For some of them, the analytical detection relies on intensive bench microscopy ...

    • Fossil pollen and spores as a tool for reconstructing ancient solar-ultraviolet irradiance received by plants: an assessment of prospects and challenges using proxy-system modelling 

      Seddon, Alistair; Festi, Daniela; Robson, T. Matthew; Zimmermann, Boris (Peer reviewed; Journal article, 2019)
      Ultraviolet-B radiation (UV-B, 280–315 nm) constitutes less than 1% of the total solar radiation that reaches the Earth's surface but has a disproportional impact on biological and ecological processes from the individual ...

    • Pollen-chemistry variations along elevation gradients and their implications for a proxy for UV-B radiation in the plant-fossil record 

      Seddon, Alistair William Robin; Festi, Daniela; Nieuwkerk, Mayke; Gya, Ragnhild; Hamre, Børge; Krüger, Linn Cecilie; Hjortland Östman, Silje Andrea; Robson, T. Matthew (Journal article; Peer reviewed, 2021)
      Research indicates that phenolic compounds (e.g. para-coumaric acid) found within pollen grains may be useful as a proxy to reconstruct the UV-B radiation received at the Earth's surface in the geological past. However, ...
