Concentrations of acrylate and dimethylsulphonioproprionate from the surface of coral reefs sampled in Moorea, French Polynesia in April 2018

Shallow-water coral reefs hold large quantities of acrylate and its precursor dimethylsulfoniopropionate (DMSP). The main sources of acrylate in coral reefs are from the coral algal symbionts in the family Symbiodiniaceae and from the photolysis of dissolved organic matter. Heterotrophic consumption is the main loss for these compounds, albeit these processes are poorly characterized. This dataset contains acrylate, DMSP, and dimethylsulfoxide (DMSO) concentrations in dissolved and unfiltered seawater samples that were collected from near-surface seawater in a Mo’orea coral reef, French Polynesia, and the offshore open Pacific Ocean. The coral reef and Pacific Ocean stations were located offshore from the UC Berkeley Gump Research Station. Samples were collected from April 6 to April 24, 2018. Details of the sampling and experimental procedures for this dataset are reported in Xue et al. (2022).
