During this engaging school activity, the students of Lycée Jules Guesde school in Montpellier had the unique opportunity to dive into the fascinating world of the deep sea.

Led by the MCAA member Pavanee Annasawmy, a marine biologist and oceanographer with nearly ten years of experience studying micronekton, they discovered the vital role these small marine organisms play in our planet’s ecosystem.


Micronekton, which includes fish, crustaceans, and squid between 2 and 20 cm in size, migrate daily from the deep ocean to surface waters. This movement, happening every night while we sleep, is crucial for transporting and storing carbon. To help students understand this phenomenon, the activity centered around “Micronekton & Eddies”, an interactive game designed by the scientist herself.


Through the game, students took on the role of micronekton, experiencing firsthand their migration patterns, interactions with predators, and the influence of oceanic eddies (circulating water masses) on their movements. This hands-on approach made complex scientific concepts accessible and fun, sparking curiosity and a deeper appreciation for marine life.

The activity provided an immersive learning experience, allowing students to explore ocean science excitingly and interactively.
