What this video covers
Luciano Candisani, underwater photographer and sailor, describes using his sailboat Oceanos as a scientific platform for environmental DNA (eDNA) sampling and documentary photography along the Brazilian coast.▶ 2:33 His earlier solo voyage aboard a smaller boat, Rivaoa, produced the book Atlântico Paulista, a photographic survey of marine biodiversity from Cananéia to Rio de Janeiro.▶ 6:48 The current Oceanos project maps biodiversity in Baía da Guanabara using eDNA water sampling: crew collect one-liter water samples, freeze them aboard, then process filters onshore to avoid working with fragile lab equipment in 2–3 meter swells.▶ 16:34 The method generates rapid species inventories — tens of thousands of species — and will track the bay's ongoing water-quality recovery, evidenced by the return of fish schools near Botafogo.▶ 12:59 The second segment features Paulo Horta, marine ecologist and professor at Universidade Federal de Santa Catarina, who leads the research sailboat Eco, the only oceanographic expedition vessel at UFSC.▶ 23:45 Eco serves dual roles: hosting graduate researchers studying pollution and climate-change impacts on marine biodiversity, and bringing schoolchildren and teachers aboard for ocean-literacy programs tied to Brazil's new legislation mandating ocean culture education.▶ 28:58 A FAPESP-funded project, nearing contract, will send Eco to Chilean Patagonia to survey kelp forest health and study seaweed as a carbon-sequestration tool highlighted at COP30.▶ 38:07 The vessel will not reach Antarctica in its current configuration; Porto Williams, at the southern tip of Chile, is the planned southern limit.▶ 40:35
