Incubation experiments were conducted in St. John, US Virgin Islands to investigate the response of reef seawater microbial communities to the mixed exudates released from the coral species Porites astreoides and Gorgonia ventalina.

<p>Other relevant files and publications:</p>

<p>The targeted and untargeted metabolomics data and metadata associated with this study are located on the MetaboLights database under accession numbers MTBLS2855 and MTBLS3286. This project is still under review at MetaboLights and has not yet been made public.</p>

<p>The 16S rRNA gene sequencing data and metadata associated with this study are located on the NCBI Sequence Read Archive (SRA) under BioProject PRJNA739882 and the data have not yet been released. I did not link BioSample accession numbers with the data submitted to BCO-DMO because samples for flow cytometry and macronutrients were not always collected at the same time as samples collected for microbial community analyses, meaning that only some of the samples collected for microbial community analyses have affiliated microbial abundances and nutrient concentrations.</p>
