I've been quite affected by the tragdy in the Maldives. The causes of this tragedy and the mistakes that lead to it will be revealed in time. But imo it's worth spending some time focusing on the people who were lost, one of whom was a leading scientist who cared deeply about the oceans and who was making a difference in the underwater world that we all love.

Monica Montefalcone, seagrass scientist, has died at 51

To Monica Montefalcone, the sea was a place to study: its plants, reefs, hidden habitats and seasonal changes. A meadow of Posidonia oceanica was not just a patch of green beneath the water. It provided nursery habitat, shelter, carbon storage and coastal protection. To most swimmers it might have looked like seagrass. To her it was a living system, and one that recovered slowly once damaged.

That slowness mattered. Across the Mediterranean, more than half of Posidonia meadows have been lost over the past century; in Liguria, the losses were especially severe. Laws and European directives could protect what remained, she argued, but protection alone was not enough. Where hundreds of hectares had disappeared, waiting for nature to repair itself would leave the work to future generations. Restoration, including the manual replanting of seagrass, was a practical response to a practical problem.

Montefalcone died on May 14th in a diving accident in the Maldives. Her daughter, Giorgia Sommacal, 23, died with her, along with Muriel Oddenino, a research fellow who had worked with her, Federico Gualtieri, a recent marine-biology graduate, and Gianluca Benedetti, a diving instructor and boat operations manager. Four of the victims were connected to the University of Genoa, where Montefalcone was an associate professor of ecology.

Her work ranged across coastal marine ecology, benthic habitats, coralligenous assemblages, marine caves, seagrass meadows and climate impacts on marine ecosystems. She mapped, monitored and measured. She also restored. WWF described her as one of the foremost experts on Mediterranean Posidonia ecosystems.

She was also a teacher. She took pride in the Marine Landscape Ecology Laboratory she coordinated at DiSTAV, but worried that young researchers in Italy often gave years of talent to a system that could not offer them stability. 

In tributes, colleagues remembered a scientist who could make the underwater world intelligible. In Mandriola, in Sardinia, where she had spent summers for decades with her family, friends remembered her swimming, running, watching sunsets, and talking about Posidonia as naturally as others might talk about the weather. Her daughter Giorgia had grown up there too.

After a death like this, the sea can seem cruel. Montefalcone’s work points to something less simple. She knew the sea as a place of beauty, risk, and damage, but also as a place where careful study could still matter. She spent her career measuring what was being lost, teaching others how to see it, and helping repair what could still be repaired. What remains is concrete: students trained, habitats mapped, meadows replanted, and a clearer understanding of a Mediterranean seafloor too often overlooked.
