A field experiment was conducted on a fringing reef on the South Shore of the island of Oahu, Hawaii, to investigate the dispersion and transport of a nearbed coastal plume. An autonomous dye source released Rhodamine WT fluorescent dye at the sea floor at a constant rate. The horizontal structure of the plume was tracked with a REMUS Autonomous Underwater Vehicle (AUV) [Hydroid, Inc.] with an onboard Turner Designs Cyclops fluorometer (Figure 1a and b; figure 2). The vertical structure of the plume and the ambient stratification was measured using an Ocean Sensors CTD with a Turner Designs Cyclops fluorometer (Figure 3). Experiments incorporated a variety of different surface wave conditions, allowing us to investigate how waves affect cross-reef plume transport (via Stokes' drift) and enhance vertical and horizontal mixing generated by the interaction of the oscillatory flow with the reef roughness.
