| contents | Uranium-thorium dating offers the possibility of absolute age determination of cold-water corals (CWCs). We present here the complementary dataset to "Radiocarbon dating of Atlantic cold-water corals over the last 32.000 years". It contains 230Th/U ages obtained on CWCs from various locations in the central and east Atlantic Ocean, as well as the Alboran Sea. It also includes an update of previously published data, necessitated by a recently discovered "ghost signal" (Kerber et al., 2023). U and Th were extracted according to the method of Wefing et al. (2017). The high precision isotopic measurements were performed on a multi-collector inductively coupled plasma mass spectrometer (MC-ICP-MS, Thermo Fisher Neptune Plus) at the Institute of Environmental Physics, Heidelberg University, Germany. For age calculations the half-lives of 234U and 230Th published in (Cheng et al., 2013) were used. The mass spectrometry setup and data treatment follows the methods recently updated in great detail by Kerber et al. (2023). |
