Examination of the diatom-bound nitrogen isotope proxy: Nitrate consumption in the polar ocean
The ratio of stable nitrogen isotopes (δ15N) is used to infer nitrogen utilization in nutrient replete surface waters through time. Typically, the isotopic composition of bulk sedimentary nitrogen (δ 15Nbulk) is measured. However the isotopic composition of this fraction is known to shift due to alt...
