Nitrogen isotopic composition of organic matter from a 168 year-old coral skeleton: Implications for coastal nutrient cycling in the Great Barrier Reef Lagoon

D.V. Erler, X.T. Wang, D.M. Sigman, S.R. Scheffers, A. Martínez-García, G.H. Haug

Ongoing human activities are known to affect nitrogen cycling on coral reefs, but the full history of anthropogenic impact is unclear due to a lack of continuous records. We have used the nitrogen isotopic composition of skeleton-bound organic matter (CS-δ15N) in a coastal Porites coral from Magnetic Island in the Great Barrier Reef as a proxy for…

Controls on the nitrogen isotopic composition of shallow water corals across a tropical reef flat transect

D.V. Erler, X.T. Wang, D.M. Sigman, S.R. Scheffers, B.O. Shepherd

We tested the hypothesis that the nitrogen (N) isotopic signature (δ15N) of coral skeletal organic material (CS-δ15N) matches that of the coral tissue and also reflects the δ15N of water column fixed N, such that CS-δ15N can be used as a proxy for spatio-temporal oceanic N isotope distributions. Strong correlations between the δ15N of skeletal…
