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.
You’d think that in the 21st century, every inch of Earth—above and below water—would already have been documented and studied. But that’s far from true. Much of the ocean floor remains elusive to scientists, and a new study shows just how much remains to be found. As the Australian Associated Press reports, scientists have discovered remnants of a massive undersea landslide that occurred 300,000 years ago off of the Great Barrier Reef.
A new study finds evidence that the last time Earth was as warm as it is today, cold freshwater from a melting Greenland ice sheet circulated in the Atlantic Ocean as far south as Bermuda, elevating sea levels and altering the ocean’s climate and ecosystems. The research shows a large pulse of cold freshwater covered the North Atlantic for a brief period of time about 125,000 years ago.
We’re in the final month of meteorological winter, and Arctic sea ice extent continues to set record lows. The low amounts of ice, compared to average, in the Arctic region have been an ongoing concern since November, and hasn’t let up through the start of February. Ice extent in the Arctic region set daily record lows through most of January, leading to the lowest January extent in the 38-year satellite record, according to the National Snow and Ice Data Center (NSIDC).
Last week in New Orleans, nearly 1,100 researchers and students from around the world met up for the annual Gulf of Mexico Oil Spill and Ecosystem Science (GoMOSES) conference to discuss “Ecosystem approaches to Gulf …
