| contents | Benthic foraminifera counts of Astrononion novozealandicum, Cibicidoides wuellerstorfi and Gyroidina umbonata, from IODP Site 306-U1314 samples. Sediment samples for benthic foraminifera analysis were collected approximately every 8 cm between 60- and 83.76-mcd, which correspond to the time interval between 780 and 1064 kyr. The age model was previously published in Hernández-Almeida et al. (2012, doi:10.1029/2011PA002209) and it is made by aligning the benthic foraminifera δ18O record (mainly Cibicidoides wuellerstorfi and Melonis pompilioides) to the LR04 benthic stack (Lisiecki and Raymo, 2005; doi:10.1029/2004PA001071). Samples used in this study were recovered during International Ocean Drilling Program Expedition 306. Site U1314 was cored in the Gardar Drift on the eastern flank of the Reykjanes Ridge, in the subpolar North Atlantic. The average sample resolution is 1 ka. Samples were dried, weighted, wet sieved over a 63 µm mesh sieved and the residue weighted again after drying. Benthic foraminifera were picked, identified, and counted from dry residues in the >125 µm fraction at University of Vigo. Each sample was split to obtain a minimum of about 200 individuals. Foraminiferal identifications were based on specialized literature. The final taxonomic assignments follow the concepts of WoRMS (last accessed on 2024-05-28). |
