Data sets

Gross primary production, respiration, and net calcification in coral reef sediments of Heron Island Lagoon, Australia, determined by in situ benthic chamber incubations C. A. Lantz, K. G. Schulz, L. Stoltenberg, and B. D. Eyre https://doi.org/10.1594/PANGAEA.883559

Short summary

This study examined the combined effect of seawater warming and organic matter enrichment on coral reef sediment metabolism. Sediments under control conditions were net autotrophic and net calcifying. Warming shifted the sediment to net heterotrophy and net dissolution, while organic matter enrichment increased net production and net calcification. When combined, the effects of each treatment were counterbalanced and sediment metabolism did not significantly differ from control treatments.
