## EyeOnWater Description
The EyeOnWater concept consists of an App and a website. The app allows you as user to make a contribution to science and supply information about the water colour of fresh- as well as saline waters (lakes, rivers, coastal waters, seas and oceans) near your location or elsewhere. The measurement is sent to the central server, validated and stored, after which it is visible via the EyeOnWater website: www.eyeonwater.org 

What is it you measure? Water colour is an indication for life (e.g. algae) in the water. Scientists have been measuring 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 timeseries.

The EyeOnWater concept has been developed by NIOZ (scientific background), Veerder (Design), and MARIS (Technical development), with assistance from other partners in the EU funded project Citclops: www.citclops.eu
