Sr/Ca in Calcitic Tests of Benthic Foraminifera - A Potential Water-Depth Proxy?
Sælen, Gunnar; Kristensen, Dorthe Klitgaard; Westerlund, Stig; Jansen, Eystein (Peer reviewed; Journal article, 2009)Well-preserved low-Mg calcite tests of modern benthic foraminifera from a depth transect off SW Norway show decreasing Sr/Ca with increasing water depth (r = –0.84). The Mg/Ca ratios also decrease with increasing water ... -
Tephra horizons identified in the western North Atlantic and Nordic Seas during the Last Glacial Period: Extending the marine tephra framework
Rutledal, Sunniva; Berben, Sarah Miche Patricia; Dokken, Trond Martin; Bilt, Willem van der; Cederstrøm, Jan Magne; Jansen, Eystein (Journal article; Peer reviewed, 2020)Geochemically distinct volcanic ash (tephra) deposits are increasingly acknowledged as a key geochronological tool to synchronize independent paleoclimate archives. Recent advances in the detection of invisible (crypto) ...
