Oregon State University researchers estimate that gray whales feeding off the Oregon Coast consume up to 21 million microparticles per day, a finding informed in part by poop from the whales.
Many of the world’s largest aquatic food producers are highly vulnerable to human-induced environmental change, with some of the highest-risk countries in Asia, Latin America and Africa demonstrating the lowest capacity for adaptation, a landmark study has shown.
The new discovery of ancient stone artefacts at an underwater spring off the WA Pilbara coast has confirmed the location is a submerged archaeological site where more ancient Aboriginal artefacts are likely hidden beneath the sea.
Pioneering analysis of deep-sea corals has overturned the idea that ocean currents contributed to increasing global levels of carbon dioxide in the air over the past 11,000 years.
Have you ever wondered what the earliest ancestors of today’s dolphins looked like? Then look no further, meet Olympicetus thalassodon, a new species of early odontocete, or toothed whale, that swam along the North Pacific coastline around 28 million years ago.
In 2018 and 2019, Sarah Kienle, Ph.D., assistant professor of biology at Baylor University, and her colleagues collected movement and dive behavior data and samples from leopard seals off the Western Antarctic Peninsula. Their goal was to compile crucial baseline data on the ecology and physiology of this enigmatic species.
The oxygen supply of the missing Titan submersible is expected to run out today around 10am GMT, or 8pm AEST. A frantic search continues for the Titan and its five occupants, with sonar buoys having recorded “banging” noises in the search area on Tuesday and Wednesday. With the vessel’s fate yet to be determined, the general public is asking questions about the safety of such touristic endeavours.
An octopus devotes about 70 percent of its brain to vision. But until recently, scientists have only had a murky understanding of how these marine animals see their underwater world. A new University of Oregon study brings the octopus’s view into focus.
Naria turdus, a sea snail first reported in U.S. coastal waters in 2022, was found underwater in Lake Worth Lagoon.
In the age of dinosaurs, many marine reptiles had extremely long necks compared to reptiles today.
Sea sponges are essential to marine ecosystems. They play critical roles in the ocean, as they provide shelter and food to a plethora of marine creatures, recycle nutrients by filtering thousands of litres of sea water daily, and are hosts to microbes that may be the key to some of the most pressing medical challenges we face today.
Pseudo-nitzschia spp., an algae that produces the neurotoxin domoic acid, can bioaccumulate within food webs causing harm to humans and animals. A molecular study of Florida’s Indian River Lagoon shows this algae was present in 87 percent of the water samples collected. All isolates showed toxicity, and domoic acid was found in 47 percent of surface water samples. As a nursery for many organisms that supports a high amount of biodiversity, the presence of domoic acid could negatively impact the lagoon system.
Sea slaters forage at night and can change colour to blend in and conceal themselves from predators. The new study, by the University of Exeter, tested the effects of a single-point light source (which casts clear shadows) and “diffuse” light (similar to “skyglow” found near towns and cities).
As we enter the summer months in the Northern Hemisphere and the possibility of extreme heat becomes more common, it’s important to stay up-to-date on the science of heat waves and take measures to protect ourselves from this growing public health threat.
Cape Cod Children’s Museum (CCCM), Woods Hole Oceanographic Institution (WHOI) and the WHOI Sea Grant program are combining forces to bring an ocean-themed educational exhibit to the CCCM, just in time for summer.
With a group of core partners, Arizona State University is creating a new $25 million collaboration to preserve and restore vitality to Hawaiʻi’s coral reefs and the health of its coastlines.
The combined emissions of metals and other environmentally hazardous substances from ships is putting the marine environment at risk according to a new study from Chalmers University of Technology, Sweden.
New research from Florida State University published in Frontiers in Marine Science found that extreme concentrations of microplastics could increase the temperature of beach sand enough to threaten the development of incubating sea turtles.
The sliver of sargassum seaweed 19-year-old Sofia Hoffman collected from the shoreline of Crandon Park Beach’s Bear Cut Preserve looked more like a dying clump of grass than the fresh piece of marine algae it once was.
The number of species of the green alga sea lettuce in the Baltic Sea region and Skagerak and is much larger than what was previously known.
To investigate the role eddies play in determining the path of the ITF, an international research group has harnessed a high-resolution ocean general circulation model that reproduces eddies.
A new study led by the University of Delaware found that while a piece of legislation designed to foster the sustainability of marine fisheries is sometimes blamed for being too stringent, other factors are far more responsible for the “underfishing” of certain fish species.
Working with live squid hatchlings at Scripps Institution of Oceanography, UC San Diego scientists find the animals can tune their proteome on the fly in response to changes in ocean temperature via the unique process of RNA recoding. The findings inspire new questions about basic protein function.
Deadly coral disease is spreading as global temperatures warm, and it’s likely to become endemic to reefs the world over by the next century, according to new research.
They’re a marine delicacy loved across Asia, but the humble sea cucumber is also proving to be a key ingredient in preventing diabetes, according to new research from the University of South Australia.
Several animal species display brood care, a phenomenon where ‘caring’ parents provide their offspring with food and protection against predators.
New work led by Carnegie’s Phillip Cleves uses cutting-edge CRISPR/Cas9 genome editing tools to reveal a gene that’s critical to stony corals’ ability to build their reef architectures.
Do whales increase the removal of carbon from the atmosphere? Despite some hope that this would be the case, a new study led by Griffith University and a team of global researchers has found the amount of potential carbon capture by whales is too little to meaningfully alter the course of climate change.
An international team of marine biologists has discovered the remnants of ancient RNA viruses embedded in the DNA of symbiotic organisms living inside reef-building corals.
The UK’s growing mismatch between the fish we catch and the fish we want to eat has clear implications for our future food security, according to new research.
Human activity has degraded ecosystems and damaged biodiversity around the world, but ecosystem restoration offers hope for the future.
New research finds that a warming climate could flip globally abundant microbial communities from carbon sinks to carbon emitters, potentially triggering climate change tipping points.
Plastic made from cane sugar also threatens the environment. Researchers from the University of Gothenburg have found that perch change their behaviour when exposed to so-called bioplastic.
In this Q&A, Berkeley Lab's Yuxin Wu discusses how scientists are developing sensing technologies that could be installed on floating offshore structures. This would allow the structures to self-monitor damaging conditions that could lead to costly repairs, and could also gauge impacts to marine mammals.
The overfishing of codfish spanning the second half of the 20th century indicates that human action can force evolutionary changes more quickly than widely believed, according to a Rutgers-led study. Published in the Philosophical Transactions of the Royal Society B: Biological Sciences, a report by scientists offers the first genomic evidence that Atlantic cod evolved new traits over only decades during a period of overfishing – evolutionary changes that scientists formerly believed could take millions of years.
The marine ecosystems of the South Atlantic Ocean have experienced a significant decline in recent decades due to overfishing and habitat degradation.
Polar fish experience lower mortality than tropical fish, allowing them to delay reproduction until later in life when they are larger and can produce more eggs, according to a study by Mariana Álvarez-Noriega at Monash University in Australia and colleagues, publishing May 25th in the open access journal PLOS Biology.
Animals using the most of efficient methods of searching for resources may well pay with their lives, scientists at the University of Bristol have discovered.
Scientists have been worried about the potential harms of microplastics for years. These small plastic particles less than 5 mm in length have been found everywhere because of plastic pollution – from the Earth’s deep oceans to remote regions in Antarctica, and even the seafood we eat.
