1. The Citclops project
• Extending historic water-quality data sets, using :
• old-fashioned techniques
• citizen science
• smartphones
• Water-quality descriptor used:
• Color
• Transparency
• Fluorescence

2. Scientific importance of color and transparency
• Besides water temperature and salinity the color
and transparency of water belong to the oldest
observed descriptors of lakes, seas and oceans.
• The color of water is an essential climate variable
defined by the World Meteorological Organization.

5. Citizens and science
• Citizens can help science by using the
smartphone app.
• Pictures and metadata are sent to the
Citclops database for further analysis.
• Historical data can be complemented
with new data collected by the citizens.
