Diatom bound nitrogen isotopes of sediment core PS69/899-2

DOI

Diatom-bound nitrogen isotopes (d15N-db) from sediment cores PS69/899-2, located in the Indian sector of the Southern Ocean, covering the past 150,000 years, based on the age model described in Fripiat et al. (doi:10.1594/PANGAEA.983936). This proxy reflects past variations in the degree of nitrate consumption in surface waters of the Southern Ocean.
