The plots show the cover of hard corals (blue), soft corals (red) and macroalgae (green) for several years of monitoring at two different water depths (2 and 5 m). These three groups are the most important components of coral reef communities. A high coral cover (more than 50%) is considered to be an indicator for a healthy coral reef community. While reefs can have low coral cover after disurbance events (e.g. cyclones, floods or coral bleaching), they should recover over time.

The plots show the water turbidity (a measure how clear the water is) and the concentration of chlorophyll (a measure of phytoplankton biomass and a proxy for nutrient availability) for several years of monitoring using continuously recording instruments.
The data can be compared to the trigger values of the Great Barrier Reef Water quality guideline (horizontal broken line). For both turbidity and chlorophyll, lower values generally indicate better water quality.

Water Quality measure | Average of all data (2005-2011) | GBRMPA Water Quality Guideline value
Particulate nitrogen (µg L-1) | 0.95 | 20
Particulate phosphorus (µg L-1) | 0.07 | 2.8
Suspended solids (mg L-1) | 0.51 | 2.0
Secchi depth (m) | 11.9 | 10
The table shows summary data of particulate nutrients and two measures of water clarity (suspended solids and Secchi depth), from direct water sampling 3 times per year, in comparison to the GBR Water Quality Guideline values.
For nutrient and suspended solids lower values generally indicate better water quality, while for Secchi depth the opposite is true: higher values indicate clearer water.
