Studying the Critical Zone...
"The Critical Zone is defined by National Research Council as the “surface and near-surface environment [that] sustains nearly all terrestrial life” and is highlighted in the report as a research focus of particular urgency, given the rapidly expanding needs of society." (Knight et al., 2010)
...with geophysical tools.
"The field of hydrogeophysics has developed in recent years to explore the potential that geophysical methods have for characterization of subsurface properties and processes relevant for hydrological investigations." (Hubbard and Linde, 2011)
Let's hear Kamini Singha talking about vadose zone Hydrogeophysics:

Through the art project of S-composition, I have been invited to make several presentations to introduce scientific notions to young children (CM1 and CM2 classes) from the Primary School Saint-Exupéry in Sevran, France.
My interventions took place on the following subjects (2024-2025):
What is the Critical Zone ? (in French)
The intricated water and carbon cycle (in French)
Following Bruno Latour concept of Geopathy and ‘Where to Land?’ workshops held with high school students, Jean-Pierre Seyvos and Chloe Latour are building up a yearly summer school on Geopathy (since 2024). Faced with the gap between the general public's scientific understanding of Earth sciences and the rapid changes affecting these disciplines, ‘geopathy’ offers everyone the opportunity to embark on a journey of re-sensitisation to the scientific, economic, political and collective realities of the Earth. Participants of these summer schools come from very different background, specialties, and interests...
My interventions took place on the following subjects:
Hands-on workshop/practice : using physical sensors and geophysics tools to characterize and image the underground.
Class on "Seeing invisible water, or how to image groundwater with the geophysical toolbox" (Voir l'eau invisible, ou comment imager l'eau souterraine avec la boite à outils géophysique, in French).
Over the years, I had the pleasure to be interviewed a couple of times:
Podcast Science #192 - Freestyle #9 (in French) : https://www.podcastscience.fm/emission/2014/11/09/podcast-science-192-freestyle-9/
Interview about Hydrogeophysics, scientific publications, and the peer reviews process.
GÉO Logique (YouTube channel) : Géodossier - "Géophysique, un nouveau "sens" pour suivre la déformation des argiles"
Interview with Emmanuel Léger (in French)
