Although less well known than its cousins, coral reefs and mangroves, seagrass plays a crucial role in climate change mitigation.
The EU continues to enter into fresh agreements with countries, despite evidence of serious population declines in the species of interest.
Despite its importance, Cameroon's maritime fisheries sector is plagued with largely hidden, or ignored, fisheries crimes.
Small-scale fisheries buffer poverty and hunger in coastal countries.
A new Intergovernmental Panel on Climate Change report makes clear human-induced climate change threatens the health and function of the ocean and cryosphere - the frozen regions of the Earth.
Fish can't read maps, and their eggs and larvae drift across national boundaries. Recent research shows that local problems in one fishery can affect others across wide areas.
Coastal communities are helping scientists understand the impacts of marine heatwaves — and find solutions.
As the oceans warm, fish are moving to stay in temperature zones where they have evolved to live. This is helping some species, hurting others and causing a net reduction in potential catch.
Food safety is in the news again, this tiime after reported deaths from listeria after eating smoked salmon. Here's what we know so far and what you can do to cut your chance of getting sick.
Sending autonomous vehicles to the Southern Ocean can be fraught with anxiety, especially if one of them doesn't make radio contact when it's supposed to.
Scientists are predicting major algae blooms in Lake Erie and large dead zones in the Chesapeake Bay and Gulf of Mexico this summer. Nutrient pollution from industrial corn farming is a major driver.
New Zealand has one of the world's largest ocean territories, but the marine environment is at risk from climate change, pollution and fishing.
The endangered Hector's dolphins are found only in coastal seas in New Zealand, but conservation experts describe New Zealand's proposed protection plan for the marine mammals as misleading.
Fish farming has been criticised for a lack of sustainability – here's what has been changing and what still remains a challenge.
West Coast fisheries policy leaves the door open to speculative investors who see opportunity and can snap up fishing licences and quotas.
North Atlantic right whales are headed toward a traumatic extinction, but could rebound if humans can get out of their way.
To ensure overall biodiversity, the intensity and impact of small-scale fisheries' methods needs far more attention.
Thousands of hydropower dams are under construction around the world. New research shows that by cutting off sediment flow, these dams can have big ecological effects on far-off bays and deltas.
For decades, New England students took field trips out into the Long Island Sound. Their data show how quickly the sound is warming, leading to fewer American lobster, rock crab and winter flounder.
With strategic planning, the marine protected area network could be a third smaller, cost half as much, and still meet the international target of protecting 10% of every ecosystem.
