What some have called the “Godzilla El Niño” is now lumbering ashore, right on schedule. El Niño tends to influence North American weather after the first of January, and indeed, we’re seeing warm temperatures in Alaska and much-needed rain in California. University of Washington researchers are tracking what the season will deliver to the Pacific Northwest region. For Washington, El Niño typically brings warm, and often dry, winter weather. That may seem surprising, since the state just experienced a very…
Along the West Coast, ocean acidification and hypoxia combine with other factors, such as rising ocean temperatures, to create serious challenges for marine life, a new study finds.
UW scientists will give free talks on climate change for three consecutive Saturdays at Mt. Baker Ski Area.
The large, fast-moving mudslide that buried much of Oso, Washington in March 2014 was the deadliest landslide in U.S. history. Since then it’s been revealed that this area has experienced major slides before, but it’s not known how long ago they occurred. University of Washington geologists analyzed woody debris buried in earlier slides and used radiocarbon dating to map the history of activity at the site. The findings, published online Dec. 22 in the journal Geology, show that a massive…
It took 100 million years for oxygen levels in the oceans and atmosphere to increase to the level that allowed the explosion of animal life on Earth about 600 million years ago, according to a study co-authored by two University of Washington scientists and led by the University College London.
A new University of Washington study confirms that composting food scraps is better than throwing them away, and also calculates the environmental benefits associated with keeping these organic materials out of landfills.
The long, slow 2014 eruption of Iceland’s Bardarbunga volcano offers a testbed to show how sulfur emissions, from volcanoes or humans, act to brighten clouds and reflect more sunlight.
A citizen science project that asks volunteers to transcribe historic ships’ logbooks to uncover data about past Arctic climate has added logbooks from hundreds of whaling ships. The hunters’ handwritten logs will provide new clues about the history of Arctic climate and sea ice.
The speed of vessels operating near endangered killer whales in Washington is the most influential factor – more so than vessel size – in how much noise from the boats reaches the whales, according to a new study published today in the online journal PLOS ONE.
Four University of Washington researchers are among 347 new fellows of the American Association for the Advancement of Science for 2015.
A new report by the University of Washington synthesizes all the relevant research about the future of the Puget Sound region to paint a picture of what to expect in the coming decades, and how to prepare.
Paleontologists with the University of Washington’s Burke Museum of Natural History and Culture find that tiny organisms called foraminifera have a big story to tell about the health of Puget Sound. Two recent studies about the health of Bellingham Bay and inlets in the Bremerton area found the diversity and number of foraminifera — single-celled marine organisms that live on the sea floor — deteriorated significantly. The decline of these microscopic organisms is consistent with the deterioration of snails and other larger marine animals, even though analysis showed a reduction of chemical pollutants in Bellingham Bay and Bremerton over the same period of time.
When President Barack Obama visited the shrinking Exit Glacier in September, he pointed to a very obvious sign of our warming planet literally at his feet. Less visible, but perhaps more indelible, signs of changing climate lie in the oceans. A University of Washington researcher argues in the journal Science that people — including world leaders who will gather later this month in Paris for global climate change negotiations — should pay more attention to how climate change’s impacts on…
A new book by University of Washington geologist David Montgomery weaves history, science and personal challenges into an exploration of humanity’s tangled relationship with microbes, perhaps the least loved and most misunderstood creatures on Earth — and in you. “The Hidden Half of Nature: The Microbial Roots of Life and Health” comes out Nov. 16 from W.W. Norton & Co. Montgomery, a UW professor of Earth and space sciences, co-wrote the book with his wife, Anne Biklé, a biologist and…
With high-tech weather radars, weather balloons, ground instruments and NASA’s DC-8 flying laboratory, scientists will be watching rain and snow storms on Washington’s famously wet Olympic Peninsula.
A new study in Ecology shows that Alaskan Dolly Varden trout, once they reach about 12 inches in length, can retire permanently from going to sea. They rely on digestive organs that can massively expand and contract and a unique relationship with sockeye salmon.
The equipment used to farm geoducks, including PVC pipes and nets, might have a greater impact on the Puget Sound food web than the addition of the clams themselves. That’s one of the findings of the first major scientific study to examine the broad, long-term ecosystem effects of geoduck aquaculture in Puget Sound.
A UW graduate student’s research paper is the first serious study of whether climate change is likely to cause human migration to the Puget Sound region.
A group of young marine-disease researchers from around the country has contributed key information about sea stars’ immune response when infected with a virus that is thought to cause a deadly wasting disease. It’s the first time researchers have tracked how genes behave when encountering this naturally occurring pathogen, which could help explain how sea stars attempt to fight the virus and why they develop lesions and appear to melt.
The first simulation of the individual crystals in volcanic mush, a mix of liquid magma and solid crystals, shows the mixing to help understand pressure buildup deep inside a volcano.
A new report published Tuesday documents all of the fishes that live in the Salish Sea. In total, 253 fish species have been recorded, and that’s about 14 percent more than in the last count.
In a commentary published Sept. 17 in Science, a team of scientists, including University of Washington researchers Jerry Franklin and James Agee, describe unique opportunities and provide suggestions to reform forest fire management to reduce the impacts of inevitable wildfires in future years.
University of Washington researchers have found the types of organisms in Seattle’s Elliott Bay change depending on the shoreline nearby, either armored or restored beaches. Young chum salmon adjusted their diets based on these changes.
Researchers from the University of Washington are awaiting the launch an over 50-foot-long rocket from a launch site in Norway into the upper reaches of the atmosphere to observe and measure a puzzling phenomenon.
A five-year, $40 million study is laying the foundation for a Pacific Northwest industry that converts sustainably produced poplar feedstock into fuels and chemicals. The research, led by the University of Washington, will seed the world’s first wood-based cellulosic ethanol production facility.
A new model for snow-fed mountain wetlands projects that the extremely dry conditions seen this year could be commonplace by the 2070s, affecting mountain species.
The membranes of sediment-entombed archaea are an increasingly popular way to determine ocean surface temperatures back to the age of the dinosaurs. But new results show that changing oxygen can affect the reading by as much as 21 degrees C.
In early August, biologist Peter Ward returned from the South Pacific with news that he encountered an old friend, one he hadn’t seen in over three decades. The University of Washington professor had seen what he considers one of the world’s rarest animals, a remote encounter that may become even more infrequent if illegal fishing practices continue. The creature in question is Allonautilus scrobiculatus, a species of nautilus that Ward and a colleague had previously discovered off of Ndrova Island…
Transmission lines that funnel power from hydroelectric dams and wind turbines across Eastern Washington affect greater sage grouse habitat by isolating fragile populations and limiting movement, a new study finds.
Recent press and social media coverage have reminded residents of the Pacific Northwest that they live in a seismically active region. Stretching offshore from northern California to British Columbia, the Cascadia subduction zone could slip at any time, causing a powerful earthquake and triggering a tsunami that would impact communities along the coast. Scientists from multiple disciplines at the University of Washington and other institutions are learning more about this hazard. Dozens of UW scientists are part of the M9…
University of Washington scientists recently announced the name of a new genus and species of frogfish, which are small, stocky creatures found in most tropical and subtropical oceans around the world.
The U.S. Geological Survey today announced $5 million in funding that will allow the University of Washington and three other institutions to help transition the prototype ShakeAlert earthquake early warning system, under development since 2005, into a public-facing tool.
New research led by the University of Washington and the Pacific Northwest National Laboratory suggests tiny ocean life in vast stretches of the Southern Ocean plays a significant role in generating brighter clouds overhead.
A two-month voyage tracking a deep current flowing from one of the most active underwater volcanoes proves that iron released from hydrothermal vents travels thousands of miles, providing a significant source of iron to support life in the broader oceans.
Despite worries about interbreeding due to climate change, a new study finds that only about 6 percent of closely related species in the Americas are likely to come into contact by the end of this century.
A UW research analyst who monitors harmful algae in Washington state is aboard a federal research vessel surveying a massive bloom that stretches from California up to Canada.
The Natural Capital Project, with offices at UW, wants to integrate the socioeconomic, cultural and spiritual values of nature into all major decisions affecting the environment and human well-being.
Oceanographers found the genetic ‘needles in a haystack’ to gain the first hints at how diatoms — tiny drifting algae that carry out a large part of Earth’s photosynthesis — detect and respond to increasing carbon dioxide from burning of fossil fuels.
Warming temperatures and decreasing levels of dissolved oxygen will act together to create metabolic stress for marine animals. Habitats will shift to places in the ocean where the oxygen supply can meet the animals’ increasing future needs.
