    • The Heliconoides Modified Dissolution Index-HMDI: Do methane seepage environments affect the preservation state of Heliconoides inflatus? 

      Beccari, Valentina; Almogi-Labin, Ahuva; Basso, Daniela; Panieri, Giuliana; Makovsky, Yizhaq; Neururer, Christoph; Hajdas, Irka; Spezzaferri, Silvia (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-05-24)
      Pteropods are holoplanktonic molluscs presently endangered because their fragile aragonitic shell is very sensitive to ocean acidification. The preservation of pteropods, and in particular of the mesopelagic Heliconoides (Limacina) inflatus, has been used to assess aragonite saturation state in Quaternary sediments (Limacina Dissolution Index, LDX) as an inferred proxy for climatic changes. Three ...

    • Late Holocene pteropod distribution across the base of the south-eastern Mediterranean margin: the importance of the > 63 µm fraction 

      Beccari, Valentina; Almogi-Labin, Ahuva; Basso, Daniela; Panieri, Giuliana; Makovsky, Yizhaq; Hajdas, Irka; Spezzaferri, Silvia (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-03-17)
      Euthecosomata pteropods were analysed in core sediments collected in the framework of the 2016 EUROFLEETS2 SEMSEEP cruise, offshore of Israel, in the eastern Mediterranean Sea. The investigated cores were retrieved in a deep-sea coral area at 690 m depth, an actively methane-seeping pockmark area at 1038 m depth, and a deep-sea channel area at 1310 m water depth. We identified and documented the ...
