Hernández-Almeida, Iván; Sierro, Francisco Javier; Filippelli, Gabriel M; Voelker, Antje H L; Diz, Paula: Organic carbon content from IODP Site 306-U1314 [dataset]. PANGAEA, https://doi.pangaea.de/10.1594/PANGAEA.980506 (dataset in review)
Abstract:
Organic carbon content from IODP Site 306-U1314 between 60-84.12 mcd, , which corresponds to ca. 779-1069 ka. 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 total carbon (TC) content of the sediment was measured in 584 samples using a UIC Coulometrics CM150 carbon analyzer at Indiana University. For total organic carbon (TOC) analyses, first we removed the total inorganic carbon (TIC) following standard procedures (Van Iperen and Helder, 1985, doi:10.1016/0025-3227(85)90167-7). About 0.2 g of powdered sample was acidified with 2N HCl in 50-mL. Samples were dried overnight, rinsed with deionized water, centrifuged, and decanted two times. Once dried, TOC was then measured using a Flash 2000 Combustion CHNS/O analyzer.
