Under the guidance of Guillaume Foissac


In 2018, the global average sea level rise reached 3 mm/year.

To this figure are added and subtracted a set of local parameters that influence this number by a factor of three.


While access to tidal data is a right, it is now impossible to access a readable and clear transcription of the disparities that exist around the world. This may suggest that the rise in water levels is uniform, whereas the territories actually evolve at very different degrees

of urgency.


Seaties is a platform which provides access to past and present tidal data, as well as comparisons and estimations for tomorrow.

It is designed for high school students, who will have the power to influence public policies in 20 years. Thanks to the juxtaposition, the isometric view allows a clear visualization of a level difference even if it is very small.


The idea is to compare data that is not usually compared, but also to group together international data that is now scattered. Finally, it was important to show the link between our daily actions and what could minimize the rise in water levels.

The global average sea level rise is now estimated on the basis of Representative Concentration Pathway (RCP) scenarios determined by the IPCC. There are 4 projections, and within each of these scenarios there are a low, medium, and high number, resulting in 12 possible numbers, ranging from a simple to a triple. This is only the calculation made to obtain the global average increase in the ocean, a figure from which a large number of parameters related to regional and local disparities are added or subtracted.
