Description

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.

These data were published in:
