(A) Map of the southern region of Kāneʻohe Bay on the island of Oʻahu (Inset) indicating locations of the Inner and Outer Lagoon reefs. Daily physicochemical dynamics of the seawater above the reef benthos at the Inner Lagoon (orange) versus Outer Lagoon (blue) reefs show the mean diel cycles of (B) seawater temperature, (C) salinity, (D) pH, and (E) DO. Diel cycles are shown as means ± 95% CI. Experimental setup at (F) the Outer Lagoon reef (image credit: The Ocean Agency) and (G) the Inner Lagoon reef.
