| Summary: | <p>This dataset contains d15N isotope data from fossil scleractinian coral (Desmophyllum dianthus) samples. Coral age from radiocarbon dating and Uranium-Thorium dating, sample depth, latitude, and longitude are also included. Deep-sea corals used in this study were collected from (1) sea-mounts south of Tasmania during cruise TN-228 in 2008–2009 on the R/V Thompson; and (2) the Drake Passage from May to June 2011 during cruise NBP1103 on the R/V Nathaniel B. Palmer.</p> <p><strong>These data were published in:</strong></p> <p>Wang, X. T., Sigman, D. M., Prokopenko, M. G., Adkins, J. F., Robinson, L. F., Hines, S. K., ... & Haug, G. H. (2017).
