Building an interdisciplinary community on the 3D study of coral skeletons
Jeudi du vivant

Where I am?
I am situated into a technological research laboratory, (that you all know well) inside a team of science engineers, the ELiA team (Engineering for Life Sciences)
My designer background and my integration in the team made me at first an observer. What do I see?

" La biologie c'est le départ, la biologie doit être la question. "
What I observe: The technological lab as a place to produce technical objects.
What I'm wondering: What's the place of design is thoses forms of production? in this production of forms? Is it "form of science" itself?
Then: How to conduct this deviation, these bifurcations?
« Sans prétendre que ces designers se positionnent comme ethnographes, nous
constaterons que leurs productions visent des objectifs comparables : décrire les systèmes
techniques, saisir les chaînes opératoires, appréhender les gestes et le langage propres aux
usages des objets techniques.»

What's coral?
Corals are small animals of the cnidarian family, that live in colonies, mostly in warm seas. They have the property to build their exoskeleton, calcareous and hard, thus forming reefs.

Coral reefs occupy barely 0.1% of the ocean's surface (or 1.2% of the continental shelves), and are home to an exceptional biodiversity with essential ecological functions. More than 25% of the world's marine biodiversity evolves in them; many species depend on them.
The ocean absorbs carbon from the atmosphere and contributes to the decrease of the CO2 level; nearly 50% of the CO2 absorption is assimilated via plankton, fish and corals.
From David Enon, « Mineral Accretion Factory ou la mer comme usine nouvelle », Techniques & Culture. Revue semestrielle d’anthropologie des techniques, no 67, 2017, p. 240‑257, personal translation
Différence entre +1,5°C (accord de Paris, 2015) et +2°C
The case of coral is symbolic, exemplary, and formidable: 40% of the reefs have disappeared and by 2050, according to IPCC forecasts, almost all of this form of life will have left the surface of our oceans.

Interdisciplinary approach
What should be produced? [and should we (still) produce?]
This is the question we wanted to ask ourselves collectively during a workshop that I organized thanks to the Axis Santé/Environnement of the lab on 20th january 2020 inbetween design, engineering and biology around coral organisms.
Engineering sciences and design practices have indeed this common trait of conceiving technical objects and thinking about their production.
An idea that has been coming back since the Italian radicals architects and designers groups of the 1970s is that of "de-projet", of making place ("Faire place"Pierre-Damien Huyghe), of eliminating by design (Tony Fry), to delete (de Noblet).

Compte-rendu dessiné des différentes idées partagées durant la JE Corail
We then define what we did not want to contribute to, what we did not want to be part of: (as feminists should say: "not in our name!")
1/ A techno-solutionist vision of scientific practices and aims
2/ Participate in the production of bio-artificial reefs
3/ "Educate" the "general public"
“ Design is a powerful analysis and repair tool. “

The injunction to repair itself is not obvious. If it is important for designers (and engineers) to question their practices, methods and postures facing erosion of biodiversity ; repairing would mean rectifying, re-establishing or restoring.
Applied to the living, repair no longer makes sense, it would rather become the search for a new dimension of life and not a return to a previous state of balance.
From the observation of the the ELiA team know-how, The Atlas-Archive of corals uses X-ray micro-tomography to archive a part of our biological heritage whose diversity decreases sharply as a result of global warming and climate changes.
To construct a common tool shared between scientists and citizens, a hybrid between an archive and a tool for "science in the making" (Latour).
We have a funding from the Dassault Foundation to take care of this project.
We also beneficiate from the Pi² technical support to produce the plateform and the database.

IUCN RED LIST OF THREATENED SPECIES
"A taxon is Critically Endangered (CR) when the best available evidence indicates that it meets any of the criteria A to E for Critially Endangered, and it is therefore considered to be facing and extremely high risk of extinction in the wild.""

The 3D Coral Library is organized around 3 main objectives:
1.An open access digital platform for the scientific community and citizens
2.3D visualization of coral structures
3.Scientific mediation of the library through exhibitions
Map of actors / partners
Following the online meeting with project stakeholders, 3 working groups are emerging
--> Culture
--> Growth
--> Perception
Each of these working groups contributes to the more global project of the Atlas/Archive and becomes a place of exchange, listening and mutual share of methods, know-how, tools and resources.
Compte-rendu de la réunion (in french and not to publish around) : here
Culture
aims to study how the coral, and particularly the larvae, behave according to the microenvironment in which they are cultured.
Growth
aims to study growth models mathematically or experimentally using 3D scanning tools.
Perception
aims to study how we can make visible and perceptible, the coral and its current issues.
For Morizot, the environmental crisis is a crisis of the sensitive. Interesting fact: the scientific knowledge is built on an evinction of the sensitive.
We are going through a cultural crisis.
It is necessary, in my opinion, to place scientific practices in a cultural approach. Putting science into culture (Levy Leblond) ; or putting scientific practices into cultural issues.

Time / scale perceptions
A paradox: we need time, we need slow down (Stengers) and yet: the disappearance is imminent, immediate, already there..
-600 million years / +40 years
Primitive corals appeared during the Paleozoic era, followed by the first forms of scleractinians from -240 million years ago. The history of corals is marked by successive extinctions over time. If these organisms with great resilience have managed to survive, it is on long time transformations and not in the particular time we are going through today. Anthropocene is the name of the geological time marked by the appearance in the earth's crust of specifically human markers. We are living in a sort of acceleration of geological time, very far from the time of biology.
How to show the different perceptions of time?

Fragments de squelettes de Lophelia
Impression 3D en argile réalisée au 8FabLab par Guillaume Barbareau (dir. artistique : Elise Rigot)
It is a field of ruins, of fragments: a collection of structures of the complex architectures that corals make with the help of biomineralization. The time of writing the material, by 3D printing process layer by layer, replay the increments of growth of corals. This slow mineralization of the skeletons allows to build the base of the reefs which shelter the marine biodiversity. Emptied of all life, only the fragments remain.

The enlargement of fragments of coral skeletons by additive manufacturing process in clay makes perceptible what is usually invisible to the human eye: microstructural information on the scale of a few microns, enlarged dozens of times to approach a sensitive experience. Reproduced as witnesses of their own extinction, sort of archive-sculptures, their petrifications proceed from a form of anticipated paleontology.

How to name what in substance already has the voice of the dead? Should we, like the neo-pagan witch Starhawk (1990), cry and lament the dismemberment of the world? To practice a vital memory.
