Dataset: Calcification data from outdoor flume experiments with coral Acropora hyacinthus at the UCB Gump Research Station Moorea, French Polynesia in September and October of 2012

Seven nubbins from upstream and downstream habitats were placed randomly in each of the 6 treatments, and calcification was measured over the 6 wk period using buoyant weighing (Davies 1989). Buoyant weight (±1 mg) was recorded at the beginning of the incubation and weekly thereafter to test for acclimation to the treatments. The difference in buoyant weight between each week of incubation was converted to dry weight using the density of aragonite (2.93 g cm−3) and used to calculate weekly rates of calcification. Calcification was normalized to surface area of the coral tissue (mg cm−2 d−1) determined using wax dipping (Stimson & Kinzie 1991). 

Parameters of the carbonate system were calculated from salinity, temperature, AT, and pHT using the R package seacarb (Lavigne and Gattuso, 2011).
