Diurnal Temperature Fluctuations

Diurnal Temperature Fluctuations

Note Water Depth CV 1: Upstream depth was approximately 30 cm more than downstream when instruments were installed, hence the consistent 30 cm more depth in upstream and downstrem1Mean along-shore velocity

Depth Averaged Velocities

De-tided Depth Averaged Velocities

Volumetric Flow Rate

Residence Time

6Heat Flux

Black dashed lines represent the maximum and minimum heat and cooling rates Advection important for cooling the reef7Velocity Profiles (upstream)

Velocity Profiles: Along (-0.2 to 0.2 m/s), Cross(-0.2 to 0.2 m/s), Vertical(-0.075 to 0.075 m/s)

Velocity Profiles: Along (-0.2 to 0.2 m/s), Cross(-0.2 to 0.2 m/s), Vertical(-0.075 to 0.075 m/s) -

9Velocity Profiles (downstream)

ADP data rotated so along shore is the flow along the principal axis. Velocity Profiles: Along (-0.2 to 0.2 m/s), Cross(-0.1 to 0.1 m/s), Vertical(-0.05 to 0.05 m/s)10
