Compare Results

All submitted data will be made available on the project website. This will make it possible to compare the condition of many different reefs at any one point in time, as well as the condition of a single reef over time. To evaluate your results, compare the distribution of your reef’s coral colour scores and coral type with all other existing data from your field site. The following graphs will be automatically generated each time you enter data.

Reef colour score distribution

This graph compares the colour score data for a particular reef, and includes all the data recorded so far for that reef, including yours! This reef appears to be very healthy!
Compare it with your survey to see if your reef’s health has changed.

Coral type distribution

This pie chart shows all coral shapes that have been recorded by all CoralWatch monitors at your site so far. Does one shape dominate over another? As we mentioned in the Your Survey section, reaction to various stressors may be influenced by coral type/species, so it is very interesting to see the shape distribution and the health of the entire reef.

Average colour score over time

This line graph shows all monitoring dates with average health scores for a specific reef. Each data point is the average of all the colour scores for that time period (month, year, etc.), from all the data collected so far. This shows how the health of your reef is progressing over time. Significant drops in your colour score can relate to threats to the reef such as bleaching, diseases, invasive species or increased tourism. From this graph, scientists would likely have looked into what naturally took place around June 2008 in this area, as well as what humans were doing, to try and figure out why such a big dip in health occurred. Although it makes for a boring graph, we want to see a high, fairly straight line across time, which means that the reef’s health is not changing much. Of course, lines that are moving upwards are even better!

Map with field sites

Our interactive map will show you all field sites where data has been collected. All data is made publicly available, creating opportunities to compare field sites all over the world and do further research. Currently there are 250 monitoring sites.

With your help, data will be available for many different regions of the world
