This map is indirectly linked to climate change!


With this map, teachers could address water quality/ health and awareness.


The level of transparency of a lake, sea or ocean depends on how deep the sunlight can penetrate in the water. The water transparency depends on the amount of particles in the water. Particles may be non-living (e.g., sediment from erosion or other dissolved material) or living (e.g., phytoplankton, microscopic algae) and give indications about water health and quality.

  • Measurements could be made in the sea, in a river, in a lake or, in the case of precipitation, at school.
  • Measurements could be made at different times (time series allowing to create graphs for specific locations) and/or different locations.
  • If each school makes measurements in three locations for example, we can have more data represented in the map.
