Planktonic foraminiferal biomineralization intensity, reflected by the weight of their shell calcite mass, affects global carbonate deposition and is known to follow climatic cycles by being increased during glacial stages and decreased during interglacial stages. [...]

12 p, 5.0 MB An evaluation of controls on planktonic foraminiferal Sr/Ca : comparison of water column and core-top data from a North Atlantic transect / Mortyn, P. Graham (Universitat Autònoma de Barcelona. Institut de Ciència i Tecnologia Ambientals) ; Elderfield, Henry (University of Cambridge. Department of Earth Sciences) ; Anand, Pallavi (Vrije Universiteit Amsterdam) ; Greaves, Mervyn (University of Cambridge. Department of Earth Sciences)
Sr/Ca in planktonic foraminifera recovered from the water column over 0-800 m along a meridional transect in the North Atlantic Ocean from 30° to 60°N were compared with data from core-top samples on the same transect and with in situ temperatures determined from water column CTD profiles. [...]

10 p, 1.9 MB Encrustation and trace element composition of Neogloboquadrina dutertrei assessed from single chamber analyses : implications for paleotemperature estimates / Jonkers, Lukas (Universitat Autònoma de Barcelona. Institut de Ciència i Tecnologia Ambientals) ; Nooijer, L. J. de (Rijksuniversiteit te Utrecht. Department of Geochemistry) ; Reichart, G. J. (Rijksuniversiteit te Utrecht. Department of Geochemistry) ; Zahn, Rainer (Universitat Autònoma de Barcelona. Institut de Ciència i Tecnologia Ambientals) ; Brummer, Geert-Jan (Koninklijk Nederlands Instituut voor Onderzoek der Zee. Department of Marine Geology)
Crust formation is a common phenomenon in planktonic foraminifera. Because of their different formation mechanism and hence composition, crusts affect the overall test composition and therefore complicate the use of crust-bearing foraminifera in paleoceanography. [...]

11 p, 804.1 KB Seasonal patterns of shell flux, δ18O and δ13C of small and large N. pachyderma (s) and G. bulloides in the subpolar North Atlantic / Jonkers, Lukas (Universitat Autònoma de Barcelona. Institut de Ciència i Tecnologia Ambientals) ; Heuven, Steven van (Cardiff University. School of Earth and Ocean Sciences) ; Zahn, Rainer (Universitat Autònoma de Barcelona. Institut de Ciència i Tecnologia Ambientals) ; Peeters, Frank J. C. (Vrije Universiteit Amsterdam)
Past water column stratification can be assessed through comparison of the δ18O of different planktonic foraminiferal species. The underlying assumption is that different species form their shells simultaneously, but at different depths in the water column. [...]

13 p, 885.5 KB Planktonic foraminifera and their proxies for the reconstruction of surface ocean climate parameters / Mortyn, P. Graham (Universitat Autònoma de Barcelona. Institut de Ciència i Tecnologia Ambientals) ; Martínez Botí, M. A. (Universitat Autònoma de Barcelona. Institut de Ciència i Tecnologia Ambientals)
Planktonic foraminifera are useful organisms to assess the surface ocean's role in climate change, due to their upper water column habitat, calcium carbonate mineral structure, and preservation in the deep-sea sedimentary record. [...]
Els foraminífers planctònics són organismes que permeten avaluar el paper que té la superfície dels oceans en el procés de canvi climàtic, a causa del seu hàbitat superficial, l'estructura calcària de la seva closca i la seva preservació al registre sedimentari oceànic. [...]

21 p, 4.0 MB Biostratigraphy of larger foraminifera in the Eocene (upper Ypresianlower Bartonian) sequences of the Southern Slope of the Western Caucasus (Russia, NE Black Sea). Correlation with regional and standard planktonic foraminiferal zones / Zakrevskaya, Federica (Vernadsky State Geological Museum RAS) ; Stupin, S. (Geological Institute RAS) ; Bugrova, E. M. (Karpinsky All-Russian Geological Research Institute (VSEGEI))
The biostratigraphic analysis of two Eocene (Upper Ypresian-Lower Bartonian) sections located on the Southern Slope of the Western Caucasus (Inal and Loo sections in the Tuapse and Sochi districts, respectively) was carried out using planktonic and larger foraminifera. [...]

18 p, 965.7 KB Centennial- to millennial-scale ice-ocean interactions in the subpolar northeast Atlantic 18-41 kyr ago / Hall, Ian R. (Cardiff University. School of Earth and Ocean Sciences) ; Colmenero-Hidalgo, E. (Universidad de León. Facultad de Ciencias Biológicas y Ambientales) ; Zahn, Rainer (Universitat Autònoma de Barcelona. Institut de Ciència i Tecnologia Ambientals) ; Peck, V. L. (British Antarctic Survey) ; Hemming, S. R. (Lamont-Doherty Earth Observatory)
In order to monitor the evolution of the British-Irish Ice Sheet (BIIS) and its influence in surface ocean structure during marine isotopic stages (MIS) 2 and 3, we have analyzed the sediments recovered in core MD04-2829CQ (Rosemary Bank, north Rockall Trough, northeast Atlantic) dated between ∼41 and ∼18 ka B. [...]
