Yes, this cephalopod is looking at you funny. It’s a kind of cockeyed squid—an animal that looks like some jokester misassembled a Mr. Potato Head. One of the cockeyed squid’s eyes is big, bulging and yellow. The other is flat and beady. After studying more than 25 years’ worth of undersea video footage, scientists think they know why.
Fossils including sharks, sea reptiles and squid-like creatures dug up in Idaho reveal a marine ecosystem thriving relatively soon after Earth’s worst mass extinction, contradicting the long-held notion life was slow to recover from the calamity.
Underwater meadows of seagrass offer important protection against pollution to both humans and coral reefs, but are in jeopardy worldwide due to climate change, sewage and agricultural runoff, researchers said Thursday. Places with healthy seagrass — where sponges, clams, small fish and other filter feeders thrive — can reduce bacteria that is harmful to both people and marine life by up to 50 percent, said the study in the journal Science.
An international team of researchers has discovered why fresh water, melted from Antarctic ice sheets, is often detected below the surface of the ocean, rather than rising to the top above denser seawater.
Imagine solving complex latent/sensible heat problems in three minutes as an auditorium filled with onlookers watches breathlessly. Or buzzing in to answer questions about ocean acidification’s impact on calcification, ocean acoustics, and maritime history before …
Using decades of global climate data generated at a spatial resolution of about 25 kilometers squared, researchers were able to capture the formation of tropical cyclones, also referred to as hurricanes and typhoons, and the extreme waves that they generate. Those same models, when run at resolutions of about 100 kilometers, missed the tropical cyclones and the big waves up to 30 meters high.
For 530 days, two algal species withstood extreme temperatures and ultraviolet radiation that would quell most other life on Earth. Part of a long-term plant study conducted aboard the International Space Station (ISS), the algae were left to grow on a panel outside the ISS for more than a year-and-a-half. Preliminary analyses of the specimens, released February 1, suggest that the plants are doing just fine.
As global temperatures rise and arctic ice melts, more ships are taking advantage of expedient, yet dangerous ocean routes that are opening in the polar region. One of the main hazards of sailing in freezing temperatures is topside icing, in which water blown from the ocean freezes once it contacts a ship, potentially accumulating enough ice to put the vessel at risk of capsizing.
Chemicals banned in the 1970s have been found in the deepest reaches of the Pacific Ocean, a new study shows. Scientists were surprised by the relatively high concentrations of pollutants like PCBs and PBDEs in deep sea ecosystems. Used widely during much of the 20th Century, these chemicals were later found to be toxic and to build up in the environment.
El Niño didn’t deliver pounding rain, but it gave California’s coastline a powerful beating during the winter of 2015/16. Rainfall levels were lower than anticipated, but beach erosion was the highest in more than 145 years, according a study released Tuesday by the U.S. Geological Survey. Scientists studied 1243 miles along the West Coast from Washington to Southern California, making 3-D surface maps, GPS topographical surveys and measuring sand, wave and water levels at each beach, and published their findings online in the journal, “Nature Communications.”
An extraordinary fossil unearthed in southwestern China shows a pregnant long-necked marine reptile that lived millions of years before the dinosaurs with its developing embryo, indicating this creature gave birth to live babies rather than laying eggs. Scientists on Tuesday said the fossil of the unusual fish-eating reptile called Dinocephalosaurus, which lived about 245 million years ago during the Triassic Period, changes the understanding of the evolution of vertebrate reproductive systems.
