Seawater samples are collected by hand from the surface and at the bottom by diver in the winter and summer in the Florida Keys. The study spanned 2016-2020 in the Middle Florida Keys with the grid extending from shore to the forereef area about 6km offshore, along about 11km of coastline. Samples of opportunity from a variety of locations in the Pacific, Indian and Atlantic Oceans were also included. Provided Keywords: strontium, trace element, seawater chemistry ABSTRACT SUPPLIED BY ORIGINATOR: A 4-year time-series of surface seawater Sr/Ca ratios was assembled across a section of the Florida Keys Reef Tract, in order to uncover any variability that might explain previously reported anomalies in regional calibrations of the coral aragonite Sr/Ca paleotemperature proxy. Samples were collected semiannually on a grid of 54 sites, from September of 2016 until January of 2020. The 325-km2 grid extended from the ocean shore to the forereef wall and from the east end of Long Key to the west end of Marathon. A novel ICP-AES method was used to measure the Sr/Ca ratio, with ratio calibration and normalization against an in-house seawater reference, yielding a long-term precision of better than 0.2%. Significant variations (2%–3%) of the seawater Sr/Ca ratio were found. While it was relatively constant offshore, near the coast the ratio alternated seasonally between higher and lower values, generally resulting in seaward Sr/Ca gradients that were markedly negative in summer but reversed in winter. Inshore seawater Sr/Ca ratios ranged from a summer high of 8.83 mmol/mol to a winter low of 8.54 mmol/mol, the difference corresponding to a potential bias of ∼5.5°C in terms of the coral Sr/Ca paleotemperature proxy. This seasonal variation should diminish the slope of empirical Sr/Ca–SST calibration lines, as has indeed been observed in prior studies with local coral species. Open ocean samples obtained from the Atlantic, Indian, and Pacific enlarge the published Sr/Ca data set for surface seawater and show a much smaller variability of 8.646 ± 0.018 mmol/mol (0.2%).
