    • Environmental evolution of the Basque Coast Geopark estuaries (southern Bay of Biscay) during the last 10,000 years 

      Cearreta, Alejandro; Irabien, María Jesús; Arozamena, José E. Gómez; El Bani Altuna, Naima; Goffard, Aintzane; García-Artola, Ane (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-04-21)
      In order to reconstruct the environmental evolution of the Deba and Urola estuaries located in the Basque Coast Geopark at millennial, centennial and decadal timescales, four long boreholes, three short cores and twelve surface samples were studied. Multiproxy analysis (foraminifera, trace metals and radioisotopes) shows the temporal transformation of these estuaries in response to regional driving ...

    • Evolución ambiental de los estuarios del Geoparque de la costa Vasca durante el Holoceno y el Antropoceno 

      Cearreta, A.; Irabien, M.J.; Gómez Arozamena, J.; El Bani Altuna, Naima; Goffard, A.; Fernández Martín-Consuegra, A.; Hilario, A. (Chapter; Bokkapittel, 2019-07)
      In order to reconstruct the environmental evolution of the estuaries in the Basque Coast Geopark at different temporal scales (millennial, centennial, decadal), different long and short cores and surface samples were retrieved and studied. Their multiproxy analysis (metals, foraminifera, pollen and radioisotopes) shows their temporal transformation in response to regional sea-level variations ...

    • Millennial‐scale changes in bottom water temperature and water mass exchange through the Fram Strait 79ºN, 63–13 ka 

      El Bani Altuna, Naima; Ezat, Mohamed; Greaves, M.; Rasmussen, Tine Lander (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-12-31)
      The Svalbard margin, in the eastern Fram Strait with its high sediment accumulation, form a key area for the reconstruction of water mass and heat exchange between the North Atlantic and Arctic Ocean in relation to abrupt climate changes as seen in glacial Greenland Interstadial and Greenland Stadial (GI‐GS) events. Here, we present a bottom water temperature (BWT) record from the northern Nordic ...
