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.
