Carbon emissions from maritime shipping and port activities are on the rise. But city ports are finding ways to reduce their carbon footprints and reconnect with nearby cities.
Contracts for exploring the deep sea are due to expire before a safe mining code can be agreed.
New research looked at wave conditions over the past 40 years, and found wave power has increased since at least the 1980s, mostly in the Southern Hemisphere.
Indigenous marine governance is experiencing a revival throughout Oceania, building on traditional worldviews that acknowledge connections between people and all parts of ocean ecosystems.
The oceans play a key role in regulating life on Earth. We must shift our view of them from as something to use if we hope to develop them sustainably.
Ocean waves are a massive source of energy, but it’s challenging to design power generators for the harsh environment. Allowing marine organisms to grow on engineered structures could help.
Sharks grow slowly and produce few young compared to bony fishes. In many cases, this means that their populations are fished out faster than can be replenished if not well managed.
Plus, why Brazilian women who lived through Zika are avoiding getting pregnant during the COVID-19 pandemic. Listen to episode 18 of The Conversation Weekly podcast.
Seabirds journey vast distances across the Earth’s seascapes to find food and to breed. This means their biology, particularly their breeding success, can reveal what’s happening in our oceans.

A study of viral variants finds Piscine orthoreovirus continuously spills over from farmed salmon to wild salmon.
Shakuntala Haraksingh Thilsted, a native of Trinidad and Tobago, is the winner of the 2021 World Food Prize for her work identifying small fish as valuable nutrition sources for developing countries.
Scientists watched in real time as rising ocean heat transformed the sprawling reef. It was a harbinger for ecosystems everywhere as the planet warms.
Sea level is still rising, and when that lunar cycle starts upward again, it will mean double trouble for places like Miami.
Climate change has already made tropical oceans too hot for some marine species to survive. As they flee towards the poles, the implications for ecosystems and human livelihoods will be profound.
Climate change is strengthening the division between the ocean surface and the abyss.
Aquaculture is a growing source of healthy protein for millions of people around the world, but there are big differences between farming fish on land and at sea.
Around 75% of fishermen in the Outer Hebrides speak Gaelic. Their daily use of the language at work helps keep it alive.
