Title

Uranium and Thorium activity data in sediment cores in the North Atlantic Ocean (NERC Grant NE/M004619/1)

Abstract

Activity (dpm/g) of Uranium and thorium isotopes from 3 sediment cores in the North Atlantic: ODP980, ODP983, EW9302-2JPC. Ocean Drilling Program (ODP) Site 980 was drilled in July 1995 in the North Atlantic Ocean, on the Feni Drift, off the eastern edge of the Rockall Plateau at 55.49°N, 14.70°W. Hole 980A Position: 55°29.087'N, 14°42.134'W. Hole 980B Position: 55°29.094'N, 14°42.137'W. ODP Site 983 was drilled was drilled in July 1995 and is located on the Bjorn Drift in approximately 1650 m water depth on the eastern flank of the Reykjanes Ridge. Hole 983A Position: 60°24.200'N, 23°38.437'W. Site EW9302-2JPC, an ODP Site Survey in 1993, of Rockall Plateau and East Flank of Reykjanes Ridge from the Flemish Cap in the south- eastern Labrador Sea (Figure 1). EW9302-2JPC Position: 4847.700 N, 4505.090 W, taken at water depth 1251m.

Quality and validity

Lineage

Sedimentary uranium (U) and thorium (Th) isotopes were measured using approximately 10 mg of dried and homogenised sediment. The sediment was spiked with a 236U- 229Th mixed spike and then totally digested with a mixed HClO4, HF, HNO3 solution in a 0.5:1:2 ratio. U and Th were separated from the matrix using the anion exchange UTEVA resin in a single column step (Nita, 2012). U and Th isotope ratios were measured using sample-standard bracketing on a Neptune Plus multi-collector inductively coupled plasma mass spectrometry (MC-ICP-MS) at the St Andrews Isotope Group (STAiG) laboratory, University of St Andrews following the procedure of (Hoffmann et al., 2007). Splice of ODP980 is as published in Crocker et al., 2016
