An interlaboratory study of Mg/Ca and Sr/Ca ratios in three commercially available carbonate reference materials (BAM RS3, CMSI 1767, and ECRM 752-1) was performed with the participation of 25 laboratories that determine foraminiferal Mg/Ca ratios worldwide. [...]

5 p, 851.5 KB Instrumental validation of Globigerinoides ruber Mg/Ca as a proxy for NE Pacific summer SST / Mortyn, Peter Graham (Universitat Autònoma de Barcelona. Institut de Ciència i Tecnologia Ambientals) ; Herguera, Juan Carlos (Centro de Investigación Científica y Educación Superior de Ensenada. Departamento de Oceanografía) ; Martínez Botí, M. A. (Universitat Autònoma de Barcelona. Institut de Ciència i Tecnologia Ambientals)
Accurate reconstruction of sea surface temperature (SST) is a high research priority, given that it is such a crucial variable in the Earth's climate system. The Mg/Ca composition of Globigerinoides ruber (white) has been calibrated and applied for a number of tropical and extratropical paleo-SST reconstructions, though validation studies of the proxy against instrumental observations are relatively scarce. [...]

16 p, 707.5 KB Nd/Ca ratios in plankton-towed and core top foraminifera : confirmation of the water column adcquisition of Nd / Martínez Botí, M. A. (Universitat Autònoma de Barcelona. Institut de Ciència i Tecnologia Ambientals) ; Vance, D. (University of Bristol. Department of Earth Sciences) ; Mortyn, Peter Graham (Universitat Autònoma de Barcelona. Institut de Ciència i Tecnologia Ambientals)
Planktic foraminifera have been used as recorders of the neodymium (Nd) isotopic composition of seawater, although there is still controversy over the precise provenance of the Nd signal. We present an extensive, multispecific plankton tow Nd/Ca data set from several geographic locations (SE Atlantic, NE Atlantic, Norwegian Sea, and western Mediterranean), together with core top samples from the Mediterranean region. [...]

14 p, 1006.0 KB Field‐based validation of a diagenetic effect on G. ruber Mg/Ca paleothermometry: Core top results from the Aegean Sea (eastern Mediterranean) / Kontakiotis, George (Panepistēmio Athēnōn.

Institut de Ciència i Tecnologia Ambientals) ; Antonarakou, Assimina (Panepistēmio Athēnōn. Department of Historical Geology and Paleontology) ; Martínez Botí, M. A. (Universitat Autònoma de Barcelona. Institut de Ciència i Tecnologia Ambientals) ; Triantaphyllou, Maria V. (Panepistēmio Athēnōn. Department of Historical Geology and Paleontology)
Recent work across the Mediterranean Sea has illustrated the salinity and overgrowth effects on planktonic foraminiferal Mg/Ca, which potentially confound the use of this as a temperature proxy for paleoceanographic reconstructions. [...]

13 p, 885.5 KB Planktonic foraminifera and their proxies for the reconstruction of surface ocean climate parameters / Mortyn, Peter 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. [...]
