Microbial sample metadata for water samples used in SourceTracker analysis, 2009-2012

<p>This dataset contains microbial sample metadata for water samples used in SourceTracker analysis, from Pickles Reef, Florida Keys National Marine Sanctuary from August of 2011 and 2012. Published in Nature Communications (2016) doi:<a href=\"http://dx.doi.org/10.1038/ncomms11833\" target=\"_blank\">10.1038/ncomms11833</a>, Supplementary Data 2d.</p> <p><u>Natural history of the study site:&nbsp;</u><br /> This experiment was conducted in the area of Pickles Reef (24.99430, -80.40650), located east of Key Largo, Florida in the United States. The Florida Keys reef tract consists of a large bank reef system located approximately 8 km offshore of the Florida Keys, USA, and paralleling the island chain. Our study reef is a 5-6 m deep spur and groove reef system within this reef tract. The reefs of the Florida Keys have robust herbivorous fish populations and are relatively oligotrophic. Coral cover on most reefs in the Florida Keys, including our site, is 5-10%, while macroalgal cover averages ~15%, but ranges from 0-70% depending on location and season. Parrotfishes (<em>Scaridae</em>) and surgeonfishes (<em>Acanthuridae</em>) are the dominant herbivores on these reefs as fishing for them was banned in 1981. The other important herbivore on Caribbean reefs, the urchin <em>Diadema antillarum</em>, remains at low densities across the Florida Keys following the mass mortality event in 1982-3.</p> <p><strong>Related Reference:</strong><br /> Zaneveld, J.R., D.E.
