The oceans are warming faster than previously estimated, setting a new temperature record in 2018 in a trend that is damaging marine life, scientists said on Thursday.
This 2020 theme for the International Day of Forests on 21 March is Forests and Biodiversity. It’s an often-quoted fact that forests are home to 80 per cent of terrestrial biodiversity, but did you know that one type of tree also supports marine biodiversity—the mangrove tree?
Scientists have collected data on a tiny sponge thought to be at risk from seabed mining. This newly discovered species could be a 'canary in a coal mine' to allow scientists to monitor the impacts of this new industry.
The oceans cover about 70% of the planet’s surface and are the main regulators of global climate. They produce much of the oxygen we breathe and support enormous biodiversity, far richer than what we see on land. But they don’t always get the recognition they deserve.
The basking shark feeds on the surface with its mouth wide open to filter plankton, explains the St. Lawrence Shark Observatory (archives).
Countless marvelous marine critters live in seagrass meadows which are easily seen in places like the Buccoo Reef marine protected area in Tobago. Dr Anjani Ganase encourages us to learn about their connections to reef and mangrove, and to allow the children to explore them.
In his new book, marine biologist and photographer Richard Smith reveals the tiny, magical world of pygmy seahorses, one of the most elusive fish on the planet
A sargassum bloom the width of the Atlantic Ocean caused havoc on beaches, but locals in Mexico and the Caribbean are fast finding ways to turn the seaweed invasion to their advantage.
When Hurricane Iris hit southern Belize in 2001, the country's magnificent corals were wrecked. But within 10 years, a radical restoration project brought the reef back to life.
That's because the sprawling seas — some 321,003,000 cubic miles of them — soak up over 90 percent of the heat trapped on Earth by human-created carbon emissions, which are still growing. This colossal heat absorption tempers the continued atmospheric warming of the remote, pale blue dot we inh ...
For a long time, the great ocean explorers used sight to reveal the secrets of the marine environment, downplaying its acoustic aspects. Indeed, the ocean has long been considered a place devoid of any sound.
A Canadian-led team of scientists has concluded that tropical coral reefs that feed millions around the world have lost about half their ability to support human communities since 1950.
It was a memorable finale to a day out on the Atlantic: a four-metre whale calf gliding past the boat as the divers returned to the Spanish island of El Hierro in the Canaries. Their incredible luck, however, would be made clear hours later, as researchers around the world clamoured for more det ...
For many South Africans, the quiet and calmness that can be found in the water – one of the rare places with few, if any, human-related threats – has been transformational.
Modelling is a necessary tool for assessing future impacts of climate change. A major comparative study Sarmiento simulated the effect of greenhouse gas emissions using six Atmosphere-Ocean General Circulation Models (AOGCMs) to examine which aspects of the models determine how ocean biology res ...
The iconic crustaceans have disappeared in waters to the south. If they keep heading north to Canada, high-flying young lobstermen may pay the biggest price.
At 100 feet long and weighing more than 100 tons, blue whales are the largest creatures to have evolved on the planet. Other whales, like killer whales, are larger than most terrestrial animals but pale in comparison to the size of blue whales.
Age Hammeken Danielsen has hunted narwhals since he was a child. He and his father would travel along Greenland’s fjords on a small motorboat, armed with rifles and harpoons and dressed in polar-bear fur trousers and sealskin boots to insulate them against the freezing weather.
Today, the Salton Sea is an eerie place. Its mirror-like surface belies the toxic stew within. Fish skeletons line its shores and the ruins of a once thriving vacation playground is a reminder of better days.
The 2018 Living Planet Index (LPI) (1) shows that populations of freshwater species have declined by an average of 83% since 1970, a far steeper drop than for terrestrial or marine species. Extinction rates for freshwater species are also exceptionally high (2).
The oceans are losing oxygen. Numerous studies based on direct measurements in recent years have shown this.
For centuries, we have thought of the ocean as unimaginably vast and unchangeable, as a sea of opportunity, spawning fishing fleets and shipping lines, building the wealth of maritime nations. The ocean fundamentally underpins the populations and food of many coastal and island states, and alway ...
It’s the end of the decade and the Great Barrier Reef is going out with a bang. Just a month ago the world watched in awe as billions of eggs and sperm exploded across large parts of the the Reef.
From the discovery of a large bioluminescent shark to the use of an innovative drone to study hurricanes, these are the best marine stories of the year
With the Pacific turning acidic in nature, Dungeness crabs residing in the coastal areas of the ocean are reportedly first to be affected by the ocean's acidification. The Dungeness crab is important to the source of income for fisheries located in the Pacific Northwest but low pH levels in the ...
As you’ve likely heard, the ocean’s health is in trouble. You’re probably aware of overfishing and the harmful practices of fisheries driving a third of the planet’s fish stocks toward extinction, and you surely know about the unconscionable amount of pollution, in particular plastic, that we du ...
Escaping predators, digestion and other animal activities—including those of humans—require oxygen. But that essential ingredient is no longer so easy for marine life to obtain, several new studies reveal.
Imagine diving into the shallow waters off the coast of Lake Michigan. You can see bare rocks and sand as you descend. Pinky-size spottail shiners swim by, shimmering in silver. When you reach the bottom, an indigenous yellow spotted molted sculpin is lying flat on its belly, flapping its boney ...
Tourists frequently flock to Lizard Island, off the northeastern coast of Australia, to marvel the Great Barrier Reef. Among the dugongs, sea turtles, and jewel-toned corals, though, there’s another organism that doesn’t get nearly as much credit as it deserves: seagrass.
The Khaled bin Sultan Living Oceans Foundation has published their findings from extensive coral reef surveys conducted in the Kingdom of Tonga.Released today, the Global Reef Expedition: Kingdom of Tonga Final Report contains critical information on the health and resiliency of coral reef ecosy ...
The biodiversity of the deep ocean is difficult to track, given its inhospitality to us – soft, air-breathing land dwellers. Down in the darkness, there's much more life than we have accounted for.
When you're a conc, mating is better in a group. In fact, it’s the only way it works. These slow-moving Caribbean sea slugs carry heavy pink and orange shells, which make chasing down mates cumbersome. To be successful, a mating ground must have some 50 or more conchs spawning at once.
The mouth of the Amazon River, which yawns out of Brazil’s rainforested north, must be a stressful place to call home. Each year, six trillion cubic meters of water—roughly enough to fill the Grand Canyon one and a half times—surge from the river into the Atlantic Ocean.
What happens when there’s a dead whale on the beach? In many reported strandings, the next steps look quite similar: where possible, biologists and veterinarians examine the carcass and conduct a necropsy to try and figure out why the mammal may have died.
A top marine biologist has urged Thailand's government to speed up conservation plans for the dugong, an imperiled sea mammal, after their death toll for the year in Thai waters has already climbed to a record 21.
Today (28 January), 102 environmental organizations, led by Seas At Risk, BirdLife Europe, ClientEarth, Oceana, Surfrider Foundation Europe and WWF are launching the ‘Blue Manifesto’. The rescue plan lays out concrete actions which must be delivered by set dates in order to turn the tide on the ...
If you live in a city or far from the ocean, the word “seafood” might evoke limited imagery. Baked fish fillet. Curry of shrimp, crab or fish. Seaweed jacketing sushi. Or a glob of caviar, if you’re able to afford it.
An "underwater garden" with more than 100 unnamed species of corals, lobsters and molluscs has been discovered on undersea mountains south of Tasmania.
Since winning the UN Environment Programme (UNEP) Young Champions of the Earth prize 12 months ago, Better Blue founder Miao Wang has taken China’s diving community by storm.
Due to the COVID-19 pandemic, many across the world are figuring out how to move forward with day-to-day activities as the plans to address the health, socio-economic and recovery issues take shape. But nature, now more than ever, needs us to pay attention to its warning signals and to take care ...
Halting overfishing and the plastic pollution of the oceans could help tackle the climate emergency by improving the degraded state of the world’s biggest carbon sink, a report has found.
Seagrass meadows are among the most important ecosystems on our planet. According to an estimate, about 50 million tiny invertebrates and 40,000 fish can thrive in just one acre of seagrass.
Sweden has become the newest member of the UK’s Global Ocean Alliance, which looks to help drive urgent action towards the 30by30 target, which would safeguard 30% of the ocean by 2030 and so helping to protect marine wildlife.
The remote Galápagos islands offer a distressing reminder of the destructive power of our plastic addiction with horrifying images of iconic species struggling on rubbish-strewn shorelines that were for so long a byword for isolation and purity.
The barrier reefs are dying, and climate change is putting the ocean and subsequently, the best surf spots, in jeopardy. Australia’s Great Barrier Reef is the world’s most extensive ecosystem, but is one of the World Heritage Sites that is under threat, and has “lost more than half its coral in ...
Le parc marin de la Côte Bleue, à quelques milles de Marseille, fait partie des dix sites français inscrits sur la « liste verte » de l’Union internationale pour la conservation de la nature.
Few corals are safe from warming oceans, a new study warns, but studies are finding surprisingly hardy corals, natural sunscreens and how coral ‘IVF’ can regrow reefs
Scientists from the Max Planck Institute for Marine Microbiology have found mountains of sugar beneath seagrass meadows across the world's oceans. Seagrass meadows are extremely efficient at capturing carbon, and are one of the world's top carbon capturing ecosystems.
Many scientists around the world are studying marine biodiversity—the variety of life forms in the ocean.
Akumal, Q.R. — A new study released by the Centro Ecológico Akumal (CEA) says that approximately half of the coral reef specimens in Akumal are infected with white syndrome disease, which in the past year, has created a mortality rate equivalent to that of the past 10.
