We examined the importance of nonlocal turbulence to the mass transfer of dissolved species from both cylinders and models of reef coral. Solid gypsum cylinders and gypsum‐coated model coral were dissolved in an outdoor flume at mean flow speeds of 4.5 and 10 cm s −1 . Three model corals were used: two branched forms of the genera Acropora and Pocillopora , and one lobate form of the genus Platygyra . Turbulence intensities (T...

Maximum rates of phosphate, nitrate, and ammonium uptake by a reef flat community were estimated from rates of frictional dissipation that were calculated from the attenuation of waves propagating over the Kaneohe Bay Barrier Reef flat. Time‐averaged flow speeds across the entire study area ranged from 0.08 to 0.22 m s −1 . Observed decreases in wave energy fluxes and near‐bottom orbital velocities gave a mean estimate for the...

The pigmentation of a cyanobacterial mat located in Rangiroa atoll (French Polynesia) was characterized using low‐altitude (500 m) Compact Airborne Spectrometer Imager hyperspectral measurements. Peaks in second and fourth derivatives of the reflective absorptance can be explained by chlorophyll and carotenoid pigments, which were independently identified by high‐pressure liquid chromatography. Phycobilin pigments were also de...
