Description:
Abstract:
Time-series of seawater carbonate chemistry variables, including salinity, dissolved inorganic nutrients, pH, total alkalinity, and dissolved inorganic carbon from sites along Kahekili Beach Park, west Maui near submarine groundwater seeps and living coral reefs. Samples for seawater were collected by pumping bottom water from the seafloor using a peristaltic pump and collecting discrete water samples every 4-hrs over a 6-day period.
Purpose:
These samples were collected and analyzed to characterize the diurnal variability in water carbonate chemistry and determine exposure to extremely low pH and high nutrient conditions linked to contaminated submarine groundwater discharge.

carbonate chemistry measurements (total alkalinity and dissolved inorganic carbon concentrations)
Source_Contribution:
Total alkalinity concentrations were measured following the spectrophotometric methods of Yao and Byrne (1998)). Dissolved inorganic carbon concentrations were measured using a UIC carbon coulometer model CM5014 and CM5130 acidification module following the methods of Dickson and others (2007). The pH value was determined by spectrophotometric methods using an Ocean Optics USB2000 spectrometer and thymol blue indicator dye following protocol of Zhang and Byrne (1996). For low salinity (< 10) water samples, discrete dissolved inorganic carbon samples were measured on an Apollo SciTech AS-C3 DIC autoanalyzer via sample acidification followed by non-dispersive infrared CO2 detection using a LiCOR 7000.
