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.

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).
