Samples for seawater chemistry were collected in Niskin and borosilicate bottles and analyzed for total alkalinity (TA), dissolved inorganic carbon (DIC), and nutrients following standard procedures as indicated in the supplemental information.
Seawater samples from Palauan reefs were collected during daylight hours in September 2011 and March 2012. Samples from Rose Atoll, Palmyra Atoll, Kingman Atoll, and Jarvis Island were collected during NOAA Pacific Reef Assessment and Monitoring Program (RAMP) cruises during daylight hours of March/April of 2006, 2008 2010, 2012, and a September 2012 cruise to Jarvis Island. Panama Ω and nitrate are taken from Manzello et al. (2008) and D’Croz and O’Dea (2007), respectively. Parentheses indicate climatological values from World Ocean Atlas and the Global Data Analysis Project (GLODAP).
Aragonite saturation state was determined from TA and DIC of seawater preserved with HgCl2 following methods and calculations described in Shamberger et al. (2014). The mean absolute differences in Ω and nitrate between 12 duplicate samples were 0.035 and 0.13 mM, respectively. Nitrates reported from the Panama sites in this dataset are from D’Croz, L., and O’Dea, A. (2007).
