A standard suite of nutrient parameters (nitrate, nitrite, ammonium, urea, total nitrogen, orthophosphate, total phosphorus and silica) monthly from 2016 to 2018. Water quality problems, including sedimentation and over enrichment of nutrients, are a major threat to coral reefs worldwide, especially in near shore reefs. In the South Florida Reef Tract, extends from Biscayne Bay National Park in the south to St. Lucie Inlet in the north, local stakeholder perception is that water quality is negatively impacting the reef. However, there is currently little evidence to support that contention, partially due to a relative lack of water quality data in the reef habitats. At the request of the Florida Department of Environmental Protection (FDEP) and the Southeast Florida Coral Reef Initiative (SEFCRI), this study quantified the water quality conditions of the reef tract across its 109 mile extent, including the contribution of inlets and offshore wastewater outfalls. It should be noted that this dataset contains data for both St. Lucie and Government Cut. A parallel effort by Florida Department of Environmental Protection quantified the same analytes at the other seven Inlet Contributing Areas in the region (Baker’s Haulover, Port Everglades, Hillsboro, Boca Raton, Boynton Inlet, Lake Worth and Jupiter). Both datasets are discussed in Whitall et al., 2019.

(1967). • Ammonium analysis was based on the method of Harwood and Kuhn (1970) using dichloro-isocyanurate as the oxidizer. • Urea was measured using diacetyl-monoximine and themicarbozide with colorimetric analysis. • The total concentration of nitrogen was determined after an initial decomposition step. This method involves persulfate oxidation while heating the sample in an autoclave (115°C, 20 minutes) (Hansen and Koroleff, 1999). After oxidation of the samples, nitrogen determination was conducted on the Astoria Pacific analyzer for nitrate. • The total concentration of phosphorus were determined after an initial decomposition step. This method involves persulfate oxidation while heating the sample in an autoclave (115°C, 20 minutes) (Hansen and Koroleff 1999). After oxidation of the samples, phosphorus determination was conducted on the Astoria Pacific analyzer for orthophosphate. • Silicate determination was accomplished using the methods of Armstrong et al. (1967) using stannous chloride.; Data Quality Method: All laboratory data contained blanks, spikes and percent recoveries. Data were QA/QC’d using National Status and Trends protocols. asNeeded Metadata are developed, maintained and distributed by NCEI. Updates are performed as needed to maintain currentness.
