Seawater samples are . 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 in Khare et al., 2022 were sampled collected by hand from the surface and at the bottom by diver in the winter and summer in the Florida Keys. Samples of opportunity were collected by hand from a variety of locations in the Pacific, Indian and Atlantic Oceans. Samples from Hughes et al., 2025 were collected at 4 sites in the Florida Keys spanning across the shelf from Florida Bay to the forereef area via osmotic pumps into teflon tubing that was subsequently subsampled and analyzed in the laboratory. OSMO sampler dates are based on known days of pump deployment and retrieval, sample volume and pump rates. Other samples were collected on known dates indicated. Provided Keywords: strontium, trace element, seawater chemistry, Sr/Ca ABSTRACT SUPPLIED BY ORIGINATOR: Coral skeletal Sr/Ca ratios are a commonly used paleotemperature proxy that relies on stable seawater Sr/Ca ratios (Rsw). Recent observations call this assumption into question at some locations, particularly in the Florida Keys, USA. We report here approximately weekly-resolved Rsw time series data collected from the Florida Keys and shorter 24 hour time-series from other coral reef sites throughout the Caribbean to quantify the magnitude and character of Rsw variability and to assess the potential impact of such variations on coral Sr/Ca-based paleoclimate reconstructions. Continuous seawater samples were collected for four years in the Florida Keys with four bottom-mounted osmotic pumps placed in a transect from inside Florida Bay to approximately 10km offshore. Rsw cycles annually in Florida Bay with high values in the summer and an amplitude of 0.4–0.5 mmol/mol which attenuates and becomes less periodic with increasing distance from shore. We suggest that the Sr/Ca cycle is potentially due to a seasonal biogeochemical process related to the precipitation and dissolution of CaCO3 in Florida Bay with the signal carried onto the shelf through mixing. The annual Rsw cycle can explain the reduced Sr/Ca-SST slopes that have been reported in local corals. Some quantitative examples of the potential effect of our observations on coral Sr/Ca ratios are discussed. The 24-hour time series show smaller excursions in seawater Sr/Ca that appear to reflect local tides and hydrography, but that illustrate the potential for substantial Rsw variations on reefs outside of the Florida Keys.
