The network protects 30 percent of the sea around the Azores, covering 287,000 square kilometers, half of which are fully protected from natural resource exploitation and the other half…

Oyster reefs along the Adelaide coastline in South Australia, Australia, have been successfully restored. Marine scientists from the University of Adelaide constructed 14 limestone reefs at the site in late 2020, and in just two and a half years the habitat has been transformed into a thriving marine metropolis, providing an important template and guide…

The Humboldt penguin population along Chile’s central coast is at risk of extinction after a sharp decline, Reuters reports.

Researchers at the Laboratory of Dynamic Leg Systems at the Politecnico di Genova, Italy, have developed a quadrupedal robot called Vero that intelligently recognizes and cleans up litter from all kinds of terrain, especially cigarette butts. Cigarette butts, which release toxic chemicals and microplastics into the ocean as they decompose, are the second most common…

As mankind’s reliance on plastics continues to grow, plastic waste is accumulating in the oceans, forming huge “garbage islands”. These plastics not only pose a direct threat to marine organisms, but also form microplastics through degradation, which further infiltrate the food chain. Recently, an international team of researchers, using a newly developed microplastic detection technique,…

Nearly one-third of the dissolved inorganic nitrogen and two-thirds of the dissolved inorganic phosphorus in the waters of the Great Barrier Reef come from groundwater at unprecedented levels, according to a study in the international journal Environmental Science & Technology. These pollutants have been transported over decades from the ground to the aquifer and then…
