These data are from the article “Seasonal carbonate chemistry dynamics on southeast Florida coral reefs: localized acidification hotspots from navigational inlets” published in Frontiers in Marine Science. The data in this package were collected from inlets and reefs along the coast of Southeast Florida. Water was collected bi-monthly from four reefs (Oakland Ridge, Barracuda, Pillars, and Emerald) and three closely-associated inlets (Port Everglades, Bakers Haulover, and Port of Miami). Water samples were collected at these locations either at the surface (~1m depth) or immediately above the benthos measured using a rosette sampler (ECO 55, Seabird). Temperature was recorded at each depth using a CTD (SBE 19V2, Seabird). Turbidity (NTU) was measured at time of water collection. Once collected, water samples were transferred to borosilicate glass bottles, samples were fixed using 200 µL of HgCl2 and sealed using Apiezon grease and a glass stopper. Salinity was measured using a densitometer (DMA 5000M, Anton Paar), while total alkalinity (TA) and dissolved inorganic carbon (DIC) were determined using Apollo SciTech instruments (AS-ALK2 and AS-C3, respectively). All values were measured in duplicate and corrected using certified reference materials following recommendations in Dickson et al. (2007). Aragonite saturation state (ΩArag.), Calcite saturation state (ΩCa), pH (Total scale), and the partial pressure of CO2 (pCO2) were calculated with CO2SYS (Lewis and Wallace, 1998) using the dissociation constants of Mehrbach et al. (1973) as refit by Dickson and Millero (1987) and Dickson (1990). Water samples were reserved for nutrient analyzed at time of collection to determine Total Kjeldahl Nitrogen, Total Phosphorus, and fluorescence of Chlorophyll-a. This research was supported through NOAA’s Coral Reef Conservation Program.

This dataset includes chemical, discrete sample, physical and profile data collected from MELVILLE in the Coral Sea and South Pacific Ocean from 1994-03-27 to 1994-06-25. These data include ALKALINITY, CHLOROFLUOROCARBON-11 (CFC-11), CHLOROFLUOROCARBON-12 (CFC-12), DELTA CARBON-14, DELTA HELIUM-3, DISSOLVED INORGANIC CARBON, DISSOLVED OXYGEN, HELIUM, HYDROSTATIC PRESSURE, NEON, NITRATE, NITRITE, PHOSPHATE, Potential temperature (theta), SALINITY, SILICATE, Tritium (Hydrogen isotope), WATER TEMPERATURE and pH. The instruments used to collect these data include CTD and bottle. These data were collected by Christopher D. Winn of Hawaii Pacific University (HPU), Frank J. Millero of Rosenstiel School of Marine and Atmospheric Science (RSMAS), and Catherine Goyet of University of Perpignan Via Domita (UPVD) as part of the WOCE_P21 dataset. The World Ocean Circulation Experiment (WOCE) was a major component of the World Climate Research Program with the overall goal of better understanding the ocean's role in climate and climatic changes resulting from both natural and anthropogenic causes. The CO2 survey took advantage of the sampling opportunities provided by the WOCE Hydrographic Program (WHP) cruises during this period between 1990 and 1998. The final collection covers approximately 23,000 stations from 94 WOCE cruises.

This dataset consists of carbonate chemistry discrete profile data collected on two of the Northeast US Coast Shelf LTER cruises, EN617 and EN627 summer 2018 and winter 2019. The dataset includes in situ temperature, salinity, and dissolved oxygen as measured from a CTD, and also includes discrete samples for dissolved inorganic carbon and total alkalinity.

This dataset contains bottle data for dissolved inorganic carbon (DIC) and total alkalinity (TA) for the period January 2016 through December 2022. The bottle samples were collected approximately every two weeks, weather permitting, from approximately 20 cm below the sea surface at the four buoys comprising our network. Commonly challenging weather and sea state conditions at the Kaneohe buoy have rendered the collection of bottle-validation samples more difficult, hence fewer data are available for this station. Collection of samples at the CRIMP-2, Ala Wai, and Kilo Nalu buoys, however, has been more readily achievable and proportionally more data are available for these buoys.
