Abstract

Masstransfer rates between water and benthos are derived based on the dissipation of energy by the benthic communities of coral reefs Roughness of the benthic communities causes currents and waves to dissipate energy on reef flats at rates which far exceed ocean values of energy dissipation The derivation here shows that firstorder rate constants for nutrient uptake are 1 proportional to energy dissipation to the 025 root 2 proportional to the bottom shear stress to the 04 root and 3 proportional to current speed to the 075 root decreasing to the 04 root under extreme wave activity The shear stress thus nutrient uptake is positively correlated to the largescale roughness and to excess wave height above the breaking height of incoming waves These causal relationships between nutrientuptake rates and dissipation of energy support the general observations of reef zonation and reef metabolic rates and are the paramount reason that coral reefs can maintain high productivity in lownutrient tropical waters
