## What is EyeOnWater?

The EyeOnWater Australia app allows you as a user to contribute to science and supply information about the water colour of fresh- as well as saline waters (lakes, rivers, coastal streams, seas, and oceans) near your location or elsewhere. Your measurements are validated and stored on a central server, after which they are visible on the EyeOnWater website: www.eyeonwater.org.

What is it you measure? You can send measurements for water colour, PH, conductivity, Secchi disk depth and others.

Water colour is an indication for life (e.g., algae) in the water. Scientists have measured this in marine waters via the Forel-Ule scale for more than 200 years. Your measurements will contribute to this long-term observation and continue the time series. 

Furthermore, by using the special EyeOnWater Australia backpack, you can do measurements for other variables such as PH, conductivity and Secchi disk depth.
