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.
With fish stocks declining globally, more than 190 countries recently made a commitment to protect about a third of the world’s oceans within “Marine Protected Areas,” or MPAs by the year 2030.

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.
