Australian researchers have embarked on an expedition to explore previously undocumented deep-sea coral reefs off the country's north coast.
Overfishing and smuggling of this crucial animal are affecting biodiversity and the livelihood of local fishers in Sri Lanka.It’s after sunset in Jaffna when Anthony Vigrado dives into the waters of Palk Bay, scanning the seafloor to collect what seems to be prized treasure. What he comes back w ...
Everyone must strike out on their own. It is something many parents discuss with their children. For Alwin Hylkema, the founder of Modular Restoration Reef Moreef in Saba, this question bears a special relevance as he works to improve the health of reefs.
Dolphins face an increasing risk of disturbance from people taking to the sea on boats, jetskis, paddleboards and kayaks as lockdown eases, campaigners have warned.
Authorities in Ghana are investigating the deaths of hundreds of dolphins and fish that washed up on beaches in Ghana in recent days, as fears grow that contaminated fish have been sold to customers.
What would a tropical reef look like if it could escape the man-made perils of global heating and overfishing? A new study suggests it would look like Rowley Shoals, an isolated archipelago of reefs 260km off Australia’s north-west coast.
About a third of people around the world rely on protein from the world’s oceans, rivers, and lakes. But the full nutritional value of this seafood depends upon the species diversity in the ecosystem where it was extracted, a new study by researchers at Yale and the University of British Columbi ...
The mesmerizing red algal species Phymatolithon calcareum clumps together to form habitats called maerl beds in coastal regions across the northeast Atlantic, but researchers have discovered a pocket of the algae near Cornwall in the UK that's genetically distinct from the rest of the region.
The size and impact of Pacific Ocean tsunami waves on the Australian coastline are significantly reduced by healthy coral structures in the Great Barrier Reef, research shows.
In recent years, advancements in DNA sequencing have exposed a large amount of hidden diversity in reef-building corals: species that appear identical to one another but are genetically distinct.
A tidal wave of interest is building in farming the seas. It’s part of a global rush to exploit oceanic resources that’s been dubbed the “blue acceleration.”
Correa says coral-eating predators are typically thought of as biting and weakening reef structures, generating hiding spaces for other organisms and, ultimately, beach sand. In contrast, grazing fish that crop down bushy algae get the limelight for helping reefs maintain healthy coral cover.

One day around 1986, Ted Danson was walking on the beach in Santa Monica Bay with his two daughters. At the time, Danson was the star of the beloved sitcom Cheers, in which he played the affable bartender Sam Malone. He was also feeling a growing sense of responsibility that came along with mone ...
Our society is increasingly weather and climate dependent.Data from Earth observation and meteorological satellites have become vital for forecasting the weather at all ranges, monitoring the climate, and producing timely warnings and other information that support public and private decision ma ...
Marine protection offers a combined solution to several of humanity’s most pressing challenges as global heating intensifies and fisheries struggle. But how can governments convince communities that conservation gains are worth waiting for?
Tropical waters are known for their bright sunlight above and their richly colorful biodiversity below. These two things aren’t unrelated; for the many tropical species that exhibit biofluorescence — that is, the ability to absorb light energy and reemit it as different colored light — the sunli ...
