As coral bleaching and deaths become more widespread globally, experts show that over a third of restoration projects fail and might never be scalable enough to have positive effects on reef ecosystems. The results show that major barriers to effective interventions include the small scale of restoration programs, high costs per hectare, and the tendency to restore already compromised reefs that are highly vulnerable to future heat stresses.

 

About 131 million years ago, an 11-foot-long ichthyosaur slammed snout first into the seafloor and was rapidly buried by sediments — a sequence of events that helped preserve not only her skeleton, but that of her unborn baby, along with the remains of her last meal.  These details are part of a new study from an international team published in the Journal of Vertebrate Paleontology about the pregnant marine reptile, which the team named Fiona.

Twelve distinguished science and health journalists have been awarded a highly competitive fellowship in the Logan Science Journalism Program at the Marine Biological Laboratory (MBL). Now in its 38th year, the Logan Science Journalism Program provides journalists with immersive, hands-on research training, giving them invaluable insight into the practice of science as well as some of the major news stories of today

Large-scale multidisciplinary ecological survey reveals long-term changes in the eastern Indian sector of the Southern Ocean

A new study by University of Maine researchers compares two scallop farming methods, ear-hanging and lantern net culture, over a complete grow-out cycle to determine which approach yields the best results for commercial growers. The study found that scallops grown with ear-hanging culture had slightly larger shell heights, about 1–4% greater than those in lantern nets. More significantly, ear-hanging scallops had up to 12% more adductor muscle weight. Researchers also found that ear-hanging scallops grew more quickly in optimal conditions, which are between 50 and 59 degrees Farhenheit, but were more affected by colder winter temperatures than those in lantern nets.

An Osaka Metropolitan University-led research team investigated the case of a male Asian small-clawed otter that fell down the stairs while sleeping, after which it developed left-sided paralysis.

A predictive model suggests that seabirds and marine mammals forage in the same areas where wind potential is most significant and that their populations may be at risk if wind farms are built there. The authors propose developing risk maps before the spatial planning of offshore wind farms to avoid harmful impacts on biodiversity.

Scientists have developed an AI-powered fluid simulation model that significantly reduces computation time while maintaining accuracy. Their approach could aid offshore power generation, ship design and ocean monitoring.
