Greg Rouse, a marine biologist at UC San Diego’s Scripps Institution of Oceanography, and other researchers have discovered a new species of deep-sea worm living near a methane seep some 50 kilometers (30 miles) off the Pacific coast of Costa Rica. Rouse, curator of the Scripps Benthic Invertebrate Collection, co-authored a study describing the new species in the journal PLOS ONE that was published on March 6.
New analysis shows that the global freshwater cycle has shifted far beyond pre-industrial conditions
A unique long-term study quantified the abundance of whitespotted eagle and giant manta rays in Southeast Florida. Researchers conducted 120 survey flights between 2014 and 2021 from Miami north to the Jupiter Inlet. One or both species were seen on nearly every flight and both populations appear to be stable in the region. The giant manta rays were more abundant in the south and the whitespotted eagle rays were found all along the coast. Neither species seems to be deterred by the greater human population density in Fort Lauderdale/ Miami.
Researchers have developed a rigorous real-time acoustic positioning method enhancing the accuracy of ocean bottom seismic exploration. This innovative approach addresses the significant challenges in positioning seafloor geophones, crucial for deep-sea petroleum and natural gas exploration.
Walleye are one of the most sought-after species in freshwater sportfishing, a delicacy on Midwestern menus and a critically important part of the culture of many Indigenous communities. They are also struggling to survive in the warming waters of the Midwestern United States and Canada.According to a new study published Feb. 26 in the journal Limnology and Oceanography Letters, part of the problem is that walleye are creatures of habit, and the seasons — especially winter — are changing so fast that this iconic species of freshwater fish can’t keep up.
In a first-of-its-kind study, researchers at the Georgia Institute of Technology discovered that sea cucumbers — sediment-eating organisms that function like autonomous vacuum cleaners of the ocean floor — play an enormous role in protecting coral from disease. The problem is, they've been overharvested for more than 100 years, and they're now rare.

Findings reveal how toxicant levels relate to their sex, breed, age and other demographic factors.
Tuna can build up high levels of methylmercury from feeding on contaminated prey. Despite efforts to reduce mercury emissions, researchers report in ACS’ Environmental Science & Technology Letters that levels in tuna appear to be unchanged.
Fish exposed to some pesticides at extremely low concentrations for a brief period of time can demonstrate lasting behavioral changes, with the impact extending to offspring that were never exposed firsthand, a recent study found.
The reproduction of giant sea spiders in Antarctica has been largely unknown to researchers for more than 140 years, until now.
Until recently, Orthacanthus gracilis could have been considered the “John Smith” of prehistoric shark names, given how common it was. Three different species of sharks from the late Paleozoic Era – about 310 million years ago – were mistakenly given that same name, causing lots of grief to paleontologists who studied and wrote about the sharks through the years and had trouble keeping them apart.
Studying the world’s oceans can be difficult – an NSU researcher lead a team that is working to do just that.
Researchers aim to use their science to help inform best practices and strategies to better protect fin whales in waters off NY and NJ.
One recent study estimates that the total amount of fishing line lost annually could stretch from the moon and back. A new study from Norway shows that roughly one-third of lines could be recycled.
University of Queensland-led research has shown there is more coral reef area across the globe than previously thought, with detailed satellite mapping helping to conserve these vital ecosystems.
In their new study published in the journal Global Environmental Change, researchers found that fishermen’s responses to a changing climate can be strongly influenced by how they fish and how they’re organized. The study highlights the role that distinct strategies associated with different group sizes and levels of cooperation play in how fishers respond and adapt to climate change.
Some animals live in such remote and inaccessible regions of the globe that it is nearly impossible to study them in their natural habitats.
The Circumpolar Current works as a regulator of the planet’s climate. Its origins were thought to have caused the formation of the permanent ice in Antarctica about 34 million years ago.
Tiny plankton – measuring less than 20µm (or 0.02mm) in diameter – make up the majority of plankton in the ocean and play a critical role in the planet’s health, according to new research.
Vitamin B12 deficiency in people can cause a slew of health problems and even become fatal. Until now, the same deficiencies were thought to impact certain types of algae, as well.
In a study published today in Marine Policy, researchers have unveiled striking evidence that fisheries management decisions such as spatial fisheries restrictions can increase greenhouse gas emissions.
Mangroves and saltmarshes sequester large amounts of carbon, mitigating the greenhouse effect.

Now, new research provides intricate details showing that vertebrae anatomy might support the mechanics of extreme body bending in thresher sharks, enabling these expert hunters to weaponize their tails. Using micro-CT scanning similar to CAT scans in humans and two-dimensional shape analysis, results suggest vertebral anatomy and mineralized microstructure meet the demands required for fast swimming and tail-whipping behavior seen in these species.
