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.

Average coral nitrogen isotope records generated using Monte Carlo and Kalman Filters

Methods & Sampling

Nitrogen isotopes were generated using the persulfate oxidation and denitrified method in the Sigman Lab at Princeton University. The precision of this method is 0.2 permil (d15N vs. air)]. Samples were obtained from the collections of Jess F. Adkins (California Institute of Technology) and Laura F. Robinson (University of Bristol).

For more methodology details see Wang et al. 2017.

Data Processing Description

These data are raw nitrogen isotope data generated in the Sigman Lab at Princeton University.
