Off the northeast coast of Brazil, the hot morning sun reflects off the sea’s surface as a jangada, a traditional wooden fishing boat, sways gently in the rolling waves.
From the surface, these 57 square kilometres of water are unexceptional. But dip beneath the surface — go down 20 or 30 metres — and you’ll find a spectacular seascape. Sponges, barnacles and tube worms cover rocky ledges on the ocean floor, forming a “live bottom.”
After the government allowed trawlers to come closer to Scottish shores in 1984, the marine ecosystem around the Isle of Arran steadily collapsed, as bottom-trawlers and dredgers intensively combed the seabed with their vibrating spikes.
The ocean is the most defining physical feature of Earth, covering 71% of the surface of this planet. It is home to incredible biodiversity, ranging from microscopic bacteria and viruses to the largest animal on Earth, the blue whale.
In a recent paper, my colleagues and I explored what prevents and enables community protection of coastal and marine areas in South Africa. We reviewed global and South African literature to identify common factors in these types of initiatives. We then refined this list based on interviews with ...
One hundred thousand years ago, a human cousin walked a rock-ribbed beach along the Mediterranean Sea, her head lowered and her large eyes scanning the shoreline. Now and again she stopped, bent her strong body, and picked up a seashell.
The area right next to a marine protected area is a prime fishing spot—and researchers think fishermen will pay to access it.
Did you know that on June 8, 2019, the world will be celebrating World Oceans Day? Did you also know that 71% of the Earth's surface is covered by oceans? If you didn't know, you should be thanking me right now. Without the oceans right now you and I might be nonexistent. Every living thing on t ...
Krill are best known as whale food. But few people realize that these small, shrimp-like creatures are also important to the health of the ocean and the atmosphere. In fact, Antarctic krill can fertilize the oceans, ultimately supporting marine life from tiny plankton through to massive whales a ...
Juli Berwald’s love affair with coral began when she saw her first reef in college — and it changed her life. Mesmerized by the beauty of these underwater animals, she set out on a path to study marine biology, eventually earning a Ph.D.
Marine forests (i.e. seascapes dominated by habitat-forming seaweeds1) are among the most productive ecosystems in temperate rocky coasts, enhancing biodiversity, ecosystem functioning and habitat complexity2,3.
As negotiations enter the final phase, countries are split over principles to govern exploitation; China is at the centre of the debate
From August 19 to 30, an intergovernmental conference will convene at the United Nations in New York to continue negotiations toward a treaty to ensure the conservation and sustainable use of the high seas—the two-thirds of the world’s ocean beyond the jurisdiction of any country.
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.
It’s easy to lose sight of good news amid the barrage of negative stories about the threats facing the ocean—everything from growing plastic pollution to dying coral reefs.
As a marine ecologist at the University of Tasmania in Hobart, Australia, I make about 150 dives a year, looking for threatened marine species. I focus on animals and plants that go largely unnoticed: small crustaceans and fish species such as gobies and blennies that grow 3 or 4 centimetres long.
Did you know that turtles belong to one of the oldest reptile groups in the world? Did you also know marine turtles actually swam with the dinosaurs millions of years ago?
The first study to look systemically at marine heat waves — periods when ocean temperatures spike for five days or more —found that they are happening more often, and are having a devastating impact on marine life, The Guardian reported.
Sustainably managing the world's sea areas will help preserve marine ecosystems and fight climate change and biodiversity loss. The whole world has been overwhelmed by the urgent challenges brought by the COVID-19 pandemic. But while this crisis is preoccupying the world, there are graver long-t ...
Scientists from the ARC Centre of Excellence for Coral Reef Studies at James Cook University (Coral CoE at JCU) have assessed how many corals there are in the Pacific Ocean.
EVANSVILLE, Ind., Aug. 7 (UPI) -- Scientists expect the size of the Gulf of Mexico's massive dead zone to grow in coming years, as changing global weather patterns pound the Midwest with heavier rains and more severe flooding.
Stabilising reef surfaces, remediating reefs after a ship grounding, and other science-based actions that help corals grow are among the suite of innovative actions that can improve the Great Barrier Reef’s health and resilience.
If you are looking for a waterway between land and sea, you can start by looking beneath your feet. “People think of rivers, which is a natural thing to come to mind,” said Nils Moosdorf, a professor of hydrogeology at Kiel University in Germany. “But groundwater has an invisible connection that ...
For how infamous the great white shark (Carcharodon carcharias) is, it can be a bit alarming to know that there are still large gaps in the knowledge scientists have of them. Gracing our cinematic screens for decades now, the gray-and-white toothed predator is known to make long‐distance migrati ...
The risk of widespread coral bleaching across the Great Barrier Reef has subsided after cloud and rain over the past 10 days caused “substantial cooling” of heat-stressed corals, according to the government’s reef management authority.
No one denies the cascade of climate-induced coral bleaching that devastated huge portions of the Great Barrier Reef in 2016, nor the subsequent bleaching. No one questions the Queensland government’s 2019 report (see go.nature.com/3ckg) that the reef’s condition near the shore is poor.
The number of new corals on Australia's Great Barrier Reef has plunged by 89% since unprecedented bleaching events in 2016 and 2017, scientists say. The events, which damaged two-thirds of the world's largest reef system, are now being blamed for triggering a collapse in coral re-growth last year.
Australia's Great Barrier Reef Marine Park Authority (GBRMPA) on Thursday confirmed "widespread coral bleaching" is occurring on the reef. Aerial surveys showed that "some southern areas of the Reef that had little or no bleaching in 2016 and 2017 have now experienced moderate or severe bleachin ...
There’s fresh hope for the future of the Great Barrier Reef as scientists and tourism operators are working together to grow new coral and repair the damage from mass bleaching.
The Great Barrier Reef could be heading for a third major coral bleaching outbreak in the space of five years if high ocean temperatures in the region do not drop in the next two weeks, scientists and conservationists have warned.
Freshwater bleaching of corals could occur this year as a result of flood waters from Queensland’s overflowing rivers pouring into the Great Barrier Reef, the marine park authority has warned.
A mass coral spawning has begun on Australia's Great Barrier Reef, with early indications the annual event could be among the biggest in recent years, local marine biologists said Sunday.
Parts of the Great Barrier Reef are showing signs of heat stress, raising the risk of another major coral bleaching event, scientists from the Great Barrier Reef Marine Park Authority have announced. Eastern Australia has experienced a long period of warmer than usual ocean currents, which has i ...
A small group of volunteers are mounting their own attempt to reverse the effects of climate change. They call themselves ‘coral gardeners’ and are trying to reverse the effects of global warming on Jamaica’s coral reefs.
Canada has made disappointingly little progress in preserving the variety of life in its oceans largely because of a contradiction in the federal department that’s supposed to protect it, says a group of senior scientists.
Most of the sandy beaches and bays of Goa, India’s smallest state, are dominated by tourism and fishing. Yet in the low tide pools along the a 100 km long coastline, slimy algae, known as seaweed, have been quietly flourishing. In recent years, seaweed has gained global renown as a wonder plant ...
In an interesting exercise to showcase the fish biodiversity in Chicalim bay,participants caught and counted 47 fish species and 16 shrimp species.
Global experts from the United Nations Environment Programme, The Nature Conservancy, governments, research agencies, and the private sector are coming together to share best practices in improving marine management based on lessons learned around the world.
Towering beneath sparkling waters off the coast of Australia's Palm Islands is an ancient coral community that predates the European settlement of its neighboring continent.
A team of marine biologists have welcomed the discovery of an endangered giant freshwater stingray during a recent expedition to a remote stretch of the Mekong River in Cambodia, though they warned the biodiversity of the area was under threat.
Marine explorers have discovered a "pristine" 3km (2-mile) coral reef at depths of 30m (100ft) off the coast of Tahiti, French Polynesia. It is one of the largest discovered at that depth, says the United Nations Educational, Scientific and Cultural Organization, which led the mission.
A new report urges research into geoengineering the oceans, not because it’s a good idea but because it may save us from our own mistakes.
Coral reefs are one of the world's most biologically diverse and productive ecosystems. They provide abundant ecological goods and services and are central to the socioeconomic and cultural welfare of coastal and island communities — throughout tropical and subtropical ocean countries — by contr ...
Ireland must increase the number of its protected areas to safeguard habitats, species, and ecosystems on our coasts and waterways
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.
The ground-breaking work of the Southern Cross University marine scientist who first discovered the dazzling coral sex phenomenon will be shared with Australian audiences on ABC TV’s Reef Live this weekend.
The world's oceans remain something of a mystery. And, to prove it, one photographer has revealed some of the multi-colour creatures that make up 'biological soup' in pitch-black depths of the Pacific waters near Hawaii.
When we think of mangrove forests, seagrass meadows and saltmarshes, we don’t immediately think of shark habitats.
“Why on earth would anyone give up working on tigers to focus on freshwater fish?” is the question I am asked most frequently since becoming the Executive Director of Shoal, a new initiative for freshwater biodiversity.
Corals are animals — yes, immobile animals — with peculiar sex lives.
