The installation process of this exhibition takes the form of two projections and several interconnected screens on the floor with their wiring.


The large TV screen on the floor and the two projections are generated from a computer program developed specifically to "explore" the undersea infrastructure of the Internet, its terrestrial connectivity and its visualization process in the exhibition space.


Entitled "sounding (the world)", the current version of this computer program is generated from the Atlantic Ocean and the many transatlantic cables that cross it such as:

Aeconnect-1 (2016 / 5521km)

Amitie (2022 / 7292km)

Atlantis-2 (2000 / 12000km)

Apollo (2003 / 13000km)

Atlantic-crossing-1-ac-1 (1998 / 14301km)

Dunant (2021 / 6400km)

Exa-express (2015 / 4600km)

Exa-north-and-south (2001 / 12200km)

Flag-atlantic-1-fa-1 (2001 / 14500km)

Globenet (2000 / 23000km)

Grace Hopper (2022 / 7191km)

Greenland connect (2009 / 4580km)

Greenland connect north (2017 / 680km)

Havfrueaec-2 (2020 / 7650km)

Iris (2022 / 1607km)

Marea (2018 / 6605km)

Monet (2017 / 10556km)

Tata-tgn-atlantic (2001 / 13000km)

Yellow (2000 / 7001km)

This program allows to interconnect the projection of a luminous flow representing the submarine topography of the paths of the telecommunication cables from the data accessible on the Web (Telegeography, Infrapedia) and other geographical information systems (GIS) with a second morphing projection of the satellite images corresponding to the position of the terrestrial arrival points of the cables with the littoral.

The large flat screen TV on the floor is the medium of connectivity and computer and information networking of this installation process.

It transmits and references in real time the metric information related to the elaboration of the two projections (topographic data flow, document files, city and country of connectivity, cable distance, speed, year, deepest position of the sea floor for each route).


This dashboard, also connects to several other small screens on the ground. 

These highlight the analysis, the observation and the relation between the cable residues and the sediments of the Atlantic Ocean seabed made with microscopes in the geo-scientific laboratories (GEOTOP) in undersea micro-paleontology.


The free-standing display on the left represents observations made with a petrographic microscope

Technological residues :

optical fiber

copper wire


and sediment samples containing oceanic microfossils :




The 2 screens on the ground show analyses made with a scanning electron microscope (SEM) of a sample from a sedimentary core from the central North Atlantic Ocean.


This is the computer scan relaying the electron beam tracing the surface of the samples in search of the microfossils that make them up. 


And the slide show of the microfossils found and processed in the samples: 


Pollen grains





The small screen spread apart and connected to the right of the central TV screen exposes a video sequence taken on the surface of the Atlantic Ocean.
