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…
Canada's $1.2 billion for the ocean was announced on Tuesday, September 29, 2026, in North Vancouver, and the Prime Minister called it historic. Two days later, the same government named the Pacific Link oil pipeline to the B.C. coast a project of national interest, putting it on the fast track.…
Half a million home batteries changed Australia's grid after dark, and it took about 13 months. Australia launched its Cheaper Home Batteries Program in July 2025, cutting about 30% off the upfront cost of a home battery connected to solar. By August 17, 2026, more than 507,000 had been installed…
A Kelvin wave headed towards California is about to lift the ocean along the West Coast by up to a foot, and it could hold it there for months. Nobody on the beach will see it arrive. This week's headlines called it a "thousand-mile wave set to smash into the…
Canada just pledged $1.2 billion for its oceans, and two days later the same government fast-tracked an oil pipeline to the B.C. coast. If you felt hopeful and suspicious at the same time, this episode is for you. We go line by line through what the money pays for: $740…

Singapore coral reefs could be buried under a new island. On August 23, 2026, Prime Minister Lawrence Wong announced plans for a new Western island, built over the coming decades for industry, energy and defence by merging Pulau Semakau, Pulau Bukom and Pulau Sudong with land reclamation. Pulau Hantu, Pulau…
