Ocean Science Facts or headlines? You have probably heard that the ocean will be empty of fish by 2048, and that a Greenland shark in the Arctic is 400 years old, or even 512. Both numbers came from real papers published in Science, one of the world's most respected journals.…

Dead coral reef found alive after 60 years off Benin. In the 1960s, fishing surveys off the West African coast picked up what looked like a deep-water coral reef and wrote it off as probably dead. Nobody went back to check. This summer, a team led by Gérard Zinzindohoué of…

Ocean myths spread fast, and some of the biggest ones started in real scientific papers. Today on Ocean Decoded Live, marine biologist Andrew Lewin traces two of them back to the source. Did a 2006 study say the ocean would be empty of fish by 2048? Is there a 400-year-old…

Only 4 African countries track their seagrass, and the rest of the continent's coastline is a blank on the map. A new review in the Journal of Applied Ecology, led by Professor Sophie von der Heyden at Stellenbosch University, found that just Kenya, Mozambique, South Africa and Tunisia have data…

Do sharks hear underwater sounds? Most people would say sharks find things by smell, a drop of blood in the water and the shark is on its way. Scientists at Florida Atlantic University tested hearing in wild blacktip sharks and found they can hear low sounds from far away and…

When you picture an ocean habitat worth saving, you probably picture a coral reef. Today we start with the one growing next to it. The first continent-wide review of seagrass restoration in Africa, led by Prof. Sophie von der Heyden at Stellenbosch University and published in the Journal of Applied…

Invasive species could gain a huge amount of new ground as sea level rise floods the coast. When you picture rising seas, you probably picture water in the street, a beach that's gone or a marsh going under. Every metre of coast the sea takes also becomes new ocean habitat,…

When you hear "sea level rise," you probably picture flooded streets and disappearing beaches. A new study in Nature Ecology & Evolution looks at what moves into that new water. The team modelled 122 non-native marine animals that are already established outside their home ranges. They found that more than…

Protected sharks can still be in trouble, because protection is drawn around places and sharks move between them. A whale shark at Ningaloo Reef in Western Australia swims in one of the most protected places on Earth, and a few weeks later it can be in Indonesian waters or out…
