Scientists have little understanding of the role fishes play in the global carbon cycle linked to climate change, but a Rutgers-led study found that carbon in feces, respiration and other excretions from fishes – roughly 1.65 billion tons annually – make up about 16 percent of the total carbon that sinks below the ocean’s upper layers.
Current models wrongly assume icebergs melt uniformly in warming oceans
A new USC study puts ocean microbes in a new light with important implications for global warming.
Around the world, coral reefs are under pressure from a host of stressors, including global warming, pollution, and disease events. Now, two leading groups – Nova Southeastern University and the Coral Restoration Foundation™ – are teaming up to establish a new “coral ark” for critically endangered coral species where genetically diverse corals will be housed to bank and protect their important genetic diversity.
Far underneath the ice shelves of the Antarctic, there's more life than expected, finds a recent study in the journal Frontiers in Marine Science.
A new observation network under development by the Woods Hole Oceanographic Institution (WHOI) will offer round-the-clock data about the ocean twilight zone - a dimly lit region roughly 200–1000 meters (650–3200 feet) below the surface, containing the largest amount of fish biomass on Earth. Encompassing 250,000 square kilometers (roughly 155,300 square miles) of the northwest Atlantic Ocean, the new network will offer unprecedented insight into this little-known, yet vitally important region of the sea, an area largely unexplored by scientists.
Climate change is bleaching and killing corals, but researchers from Michigan State University and the University of Hawaii are investigating how some can stand up to a warming world.
Under increasing global warming, tropical fish are escaping warmer seas by extending their habitat ranges towards more temperate waters. But a new study shows that the ocean acidification predicted under continuing high CO2 emissions may make cooler, temperate waters less welcoming.
A new study in Frontiers in Marine Science provides a first-of-its-kind evaluation of which regions of southern European seas are in the most need of fishing restrictions.
As glacial ice melts, what happens to the freshwater and how it is affecting coastal systems in Antarctica becomes an important question. The University of Delaware’s Carlos Moffat has been awarded a five-year, $787,528 National Science Foundation (NSF) Early Faculty Career Development Award.
Researchers have found new evidence that global warming is affecting the size of commercial fish species, documenting for the first time that juvenile fish are getting bigger, as well as confirming that adult fish are getting smaller as sea temperatures rise.
The findings of a new study examining the behaviours of alligator and caiman hatchlings have enhanced our understanding of how we can conserve, and increase, the population of endangered crocodilian species.
Single-celled organisms in the open ocean use a diverse array of genetic tools to detect light, even in tiny amounts, and respond. The discovery of these new genetic "light switches" could also aid in the field of optogenetics, in which a cell's function can be controlled with exposure to light.
New research out of the University of Chicago has found evidence that the lobe-finned fish species Tiktaalik roseae was capable of both biting and suction during feeding, similar to modern-day gars. These results provide evidence that bite-based feeding originally evolved in aquatic species and was later adapted for use on land.
Global warming. Climate change. Coral bleaching. These are a few issues that are negatively impacting our marine world. And now you can add underwater heatwaves to the list - something an NSU Researcher is studying.
A new University of Washington paper published Jan. 11 in Nature Sustainability quantifies the tradeoffs between hydroelectric generation capacity and the impacts on river connectivity for thousands of current and projected future dams across Brazil. The findings confirm that small hydropower plants are far more responsible for river fragmentation than their larger counterparts due to their prevalence and distribution.
A study has revealed for the first time the ancient origins of one of the world’s most important ecosystems by unlocking the mechanism which determined the evolution of its mountains and how they shaped the weather there as well as its flora and fauna.
A team of marine scientists has confirmed that southern Africa’s most threatened endemic shark – the Critically Endangered shorttail nurse shark (Pseudoginglymostoma brevicaudatum) – has been found to occur in Mozambique; a finding that represents a range extension of more than 2,000 kilometers (1,242 miles).
“Shell-crushing,” an explosive sound, occurs when marine animals crack open hard shells like clams to eat the edible tissue. There hasn’t been any data to support this feeding noise, until now. A study is the first to quantify these sounds using underwater acoustics in a marine animal in a controlled setting. Scientists know what type of shell a ray is eating based on the sound it makes and show it’s audible above ambient noise in lagoons out to 100 meters.
A nuclear war could trigger an unprecedented El Niño-like warming episode in the equatorial Pacific Ocean, slashing algal populations by 40 percent and likely lowering the fish catch, according to a Rutgers-led study. The research, published in the journal Communications Earth & Environment, shows that turning to the oceans for food if land-based farming fails after a nuclear war is unlikely to be a successful strategy – at least in the equatorial Pacific.
The Ganges River - with the combined flows of the Brahmaputra and Meghna rivers - could be responsible for up to 3 billion microplastic particles entering the Bay of Bengal every day, according to new research.
It's mid-January 2021, and the first gray whales from the eastern North Pacific population have started to arrive in the breeding lagoons in Baja California, Mexico.
Sixteen years of remote sensing data reveals that in Earth’s largest freshwater lakes, climate change influences carbon fixation trends.
New research led by BirdLife International, the University of East Anglia (UEA) and British Antarctic Survey highlights how a proposed network of marine protected areas could help safeguard some of the most important areas at sea for breeding Antarctic penguins.
Scientists have discovered how bacteria commonly responsible for seafood-related stomach upsets can go dormant and then "wake up".
The Faculty of Science, Chulalongkorn University in collaboration with Chula Unisearch, the Plant Genetic Conservation Project under the Royal Initiative of Her Royal Highness (HRH) Princess Maha Chakri Sirindhorn and the Naval Special Warfare Command, Royal Thai Navy, jointly publicized the discovery of the world’s rare and newly discovered species of soft coral. The discovery indicates the abundance and ecological diversity of the Thai seas and one of the new species has received HRH Princess Maha Chakri Sirindhorn’s gracious permission to be named “Sirindhornae“. The other was named “Cornigera“. The discovery and names of the two new soft coral species found in the Thai seas have been published in the international research journal, Zootaxa, in 2020.
Research from the University of Adelaide has found that some species of fish will have higher reproductive capacity because of larger sex organs, under the more acidic oceans of the future.
Shelled pteropods, microscopic free-swimming sea snails, are widely regarded as indicators for ocean acidification because research has shown that their fragile shells are vulnerable to increasing ocean acidity.
Partially protected areas - marine reserves that allow some forms of fishing - are no more effective socially or ecologically than open marine areas in Australia's Great Southern Reef, a new UNSW study has concluded.
In a new study, an international research team led by Sebastian Stumpf from the University of Vienna describes an exceptionally well-preserved skeleton of the ancient shark Asteracanthus. This extremely rare fossil find comes from the famous Solnhofen limestones in Bavaria, which was formed in a tropical-subtropical lagoon landscape during the Late Jurassic, about 150 million years ago.
In a proof-of-principle study, Cornell researchers describe a new technique in which they analyzed environmental DNA – or eDNA – from water samples in Cayuga Lake to gather nuanced information about the presence of these invasive fish.
A new study conducted at the New England Aquarium finds that as climate change causes the ocean to warm, baby sharks are born smaller, exhausted, undernourished, and into environments that are already difficult for them to survive in.
Climate changes prompt many important questions.
As the waters off our coasts change due to human influences, scientists have found that the composition of shells of California mussels, a critical species found along the Pacific Coast, are weakening as a result of ocean acidification.
Fish populations tend to do better in places where rigorous fisheries management practices are used, and the more measures employed, the better for fish populations and food production, according to a new paper published Jan. 11 in Nature Sustainability.
How the larvae of colorful clownfish that live among coral reefs in the Philippines are dispersed varies widely, depending on the year and seasons – a Rutgers-led finding that could help scientists improve conservation of species. Right after most coral reef fish hatch, they join a swirling sea of plankton as tiny, transparent larvae. Then currents, winds and waves disperse them, frequently to different reefs.
A new study shows that the gigantic Megalodon or megatooth shark, which lived nearly worldwide roughly 15-3.6 million years ago and reached at least 50 feet (15 meters) in length, gave birth to babies larger than most adult humans.
An invisible flow of groundwater seeps into the ocean along coastlines all over the world.
Second only to the spiny lobster, the queen conch is a prized delicacy long harvested for food and is revered for its beautiful shell. Conch populations have dwindled so low, creating a dire and urgent situation in ecological and economic terms. To preserve this most significant molluscan fishery in the Caribbean, the world’s leading expert on queen conch aquaculture has published an 80-page, step-by-step user manual that provides complete illustrations and photos of how to culture and restore the queen conch.
In the future, the Antarctic could become a greener place and be colonised by new species.
New Cornell University-led research suggests that starfish, victims of sea star wasting disease (SSWD), may actually be in respiratory distress – literally “drowning” in their own environment – as elevated microbial activity derived from nearby organic matter and warm ocean temperatures rob the creatures of their ability to breathe.
The Marine and Coastal Research Laboratory in Sequim, Washington, is the U.S. Department of Energy’s only marine research facility. It has a rich history and expanding research scope.
Bitterling fishes (Subfamily: Acheilognathinae) spawn in the gills of living freshwater mussels obligately depending on the mussels for reproduction.
