An international team including a UW scientist found that the water on one of Saturn鈥檚 moons harbors phosphates, a key building block of life. The team used data from NASA鈥檚 Cassini space mission to detect evidence of phosphates in particles ejected from the ice-covered global ocean of Saturn鈥檚 moon Enceladus.
Polar scientist Eric Regehr studies polar bears on Wrangel Island, an island off Russia that is home to the highest concentration of polar bears in the world. Regehr and UW glaciologist Ian Joughin will field audience questions after screenings of “Arctic: Our Frozen Planet,” which focuses on the changing Arctic environment.
New research shows that in Washington state, the presence of two apex predators 鈥� wolves and cougars 鈥� does indeed help keep populations of two smaller predators in check. But by and large the apex predators were not killing and eating the smaller predators, known as mesopredators. Instead, they drove the two mesopredator species 鈥� bobcats and coyotes 鈥� into areas with higher levels of human activity. And people were finishing the job.
UW will be a core member of a consortium led by Stony Brook University that will build and operate The New York Climate Exchange 鈥� a carbon-neutral international hub focused on climate action and adaptation
Two 乱伦社区 researchers are using very different methods to investigate the issue of marine microplastics. For Earth Day, UW News asked them to discuss their research.
The UW Climate Impacts Group created an interactive tool that lets state agencies and local governments see what climate scientists project for their county and what they might want to consider when developing their districts鈥� comprehensive plans through 2100.
UW oceanographers discovered warm, chemically distinct liquid shooting up from the seafloor about 50 miles off Newport. They named the unique underwater spring “Pythia鈥檚 Oasis.” Observations suggest the spring is sourced from water 2.5 miles beneath the seafloor at the plate boundary, regulating stress on the offshore subduction zone fault.
A record-breaking heat wave that baked Washington state in 2021 contributed to 159 excess injury deaths, according to research led by a UW professor.
Phil Levin, professor of practice in environmental and forest sciences at the 乱伦社区 and lead scientist at The Nature Conservancy in Washington, has been appointed to direct the first-ever U.S. National Nature Assessment. The 3-year assessment will take an interdisciplinary approach to better understand the role of nature in the lives of people across the country, and how those benefits might be altered under climate change.
The cherry blossoms at the 乱伦社区 campus are a seasonal tradition and celebration for the entire region. This year鈥檚 colder-than-usual spring is demanding a little more patience. Mark your calendars and plan your visit for a peak bloom expected in early April.
The White House Office of Science and Technology Policy and the 乱伦社区 are bringing together climate, sustainability and resilience leaders, and educators representing a cross section of colleges and universities from around the country, with federal agency leaders for a virtual forum on climate change.
Non-erupting volcanoes leak a surprisingly high amount of sulfur-containing gases. A Greenland ice core shows that volcanoes quietly release at least three times as much sulfur into the Arctic atmosphere than estimated by current climate models. Aerosols are the most uncertain aspect of current climate models, so better estimates could improve the accuracy of long-term projections.
New research finds that ice-sheet-wide collapse in West Antarctica isn鈥檛 necessarily inevitable. The pace of ice loss varies according to regional differences in atmosphere and ocean circulation.
A recent report and upcoming virtual event looks at the unequal effect of marine plastics on different communities. The international report led by UW’s Yoshitaka Ota covers topics ranging from the COVID-19 pandemic’s impact on plastic pollution to a critique of Coca-Cola’s waste initiative.
Save the … parasites? Analyzing 140 years of parasite abundance in fish shows dramatic declines, especially in parasites that rely on three or more host species. The decline is linked to warming ocean temperatures. Parasitic species might be in real danger, researchers warn — and that means not just fewer worms, but losses for the entire ecosystem.
An underwater volcanic eruption in January 2022 created ripple effects throughout the world’s atmosphere and oceans. 乱伦社区 scientists analyzed that event to show how GPS signals could help monitor future volcanoes and tsunamis.
UW’s Virtual Field Geology project has many goals: to make geology field experiences accessible to more people; to document geological field sites that may be at risk from erosion or development; to offer virtual 鈥渄ry run鈥� experiences; and to allow scientific collaborators to do virtual visits to a field site together.聽While the pandemic brought new urgency to the project, its developers believe it’s part of a “new normal” for geology research and education.
The strongest Arctic cyclone ever observed struck in January 2022. A new analysis led by the 乱伦社区 shows that while forecasts accurately predicted the massive storm, models seriously underestimated its impact on sea ice. Results suggest how forecast models for a changing Arctic Ocean could improve.
Two UW College of the Environment professors, Ginger Armbrust and Dennis Hartmann, will be honored at the 2022 American Geophysical Union Fall Meeting in December.
A new 乱伦社区-led study reports that throughout Earth鈥檚 ancient history, there were several periods of time when many fish actually favored the cold, dark, barren waters of the deep sea instead of shallow ocean waters that are warm and full of resources.
乱伦社区 researchers found that adopting permanent daylight saving time in the United States would reduce deer-vehicle collisions and likely prevent an estimated 36,550 deer deaths, 33 human deaths, 2,054 human injuries and $1.19 billion in costs each year. Deer-vehicle collisions would decrease under permanent DST because skies would be brighter later into the evening.
A new 乱伦社区-led study has found that even in remote, rarely visited national parks, the presence of even just a few humans impacts the activity of wildlife that live there. Nearly any level of human activity in a protected area like a national park can alter the behavior of animals there.
Forecasters are predicting a 鈥渢hree-peat La Ni帽a鈥� this year. This will be the third winter in a row that the Pacific Ocean has been in a La Ni帽a cycle, something that鈥檚 happened only twice before in records going back to 1950. A new study of temperature patterns in the tropical Pacific Ocean suggests that climate change is, in the short term, favoring La Ni帽as.
Shuyi Chen, a UW professor of atmospheric sciences, was traveling to a conference in Boston as Hurricane Ian approached the Gulf of Mexico. During breaks at the conference, she provided her thoughts on the closely watched catastrophic storm system that made landfall in Florida on Sept. 28. Q: What are your thoughts on Hurricane Ian? How does it compare to other storms? See also: “UW鈥檚 Shuyi Chen on hurricane science, forecasting and the 2017 hurricane season“ Shuyi Chen: Each hurricane…
Researchers dropped technology developed at the 乱伦社区 off the coast of Florida this week to measure ocean waves in the path of Hurricane Ian. The test is one part of a broad effort to improve forecasts for these fast-moving and deadly systems.
Heat-related deaths occur across Washington state, even in regions with typically milder climates. This is the most extensive study yet of heat-related mortality in Washington state, and the first to look beyond the major population to and include rural areas. Researchers used statistical methods to uncover 鈥渉idden鈥� deaths that may have listed something else, like illness or a chronic disease, as the primary cause.
A 2018 expedition that drilled farther into the seafloor than ever before — almost 2 miles — sought to take measurements of stress as close as possible to a tectonic fault off the coast of Japan. Surprisingly, the researchers found little built-up tectonic stress. The findings could help to better understand earthquakes in subduction zones around the world.
A new study projects the number of days with “dangerous” and “extremely dangerous” mixtures of heat and humidity by the end of this century. Even if global warming is limited to 2 degrees Celsius, results show that deadly heat waves will become much more common in the mid-latitudes, and many tropical regions will experience “dangerous” heat for about half the year.
Volunteers spent thousands of hours recording trash on beaches in Washington and Oregon to show that certain beaches, and certain areas of a single beach, are 鈥渟ticky zones鈥� that accumulate litter. Finding patterns for where litter lands could help to better prevent and remove trash in the marine environment.
A 乱伦社区 pilot project is exploring the use of fiber-optic sensing for seismology, glaciology, and even urban monitoring. Funded in part with a $473,000 grant from the M.J. Murdock Charitable Trust, a nonprofit based in Vancouver, Washington, the new UW Photonic Sensing Facility will use photons traveling through a fiber-optic cable to detect ground motions as small as 1 nanometer.
For birds that inhabit developed areas of the Pacific Northwest, the reduction in noise and commotion from COVID-19 lockdowns may have allowed them to use a wider range of habitats in cities, a new 乱伦社区 study has found.
As glaciers worldwide retreat due to climate change, managers of national parks need to know what鈥檚 on the horizon to prepare for the future. A new study from the 乱伦社区 and the National Park Service measures 38 years of change for glaciers in Kenai Fjords National Park south of Anchorage. The study, published Aug. 5 in The Journal of Glaciology, finds that 13 of the 19 glaciers show substantial retreat, four are relatively stable, and two have advanced. It also finds trends in which glacier types are disappearing fastest.
Air pollution is not just a problem for lungs. Increasingly, research suggests air pollution can influence childhood behavioral problems and even IQ. A new study led by the 乱伦社区 has added evidence showing that both prenatal and postnatal exposure to air pollution can harm kids. The study, published in Environmental Health Perspectives, found that children whose mothers experienced higher nitrogen dioxide聽(NO2) exposure during pregnancy, particularly in the first and second trimester, were more likely to have behavioral problems….
A new 乱伦社区 study that leverages historical data has found unique support for a 鈥渟afety in numbers鈥� hypothesis by showing that Pacific salmon in larger groups have lower risk of being eaten by predators. But for some salmon species, schooling comes at the cost of competition for food, and those fish may trade safety for a meal.
A team led by the UW has produced the first comprehensive report of the impacts of the 2021 heat wave on shellfish.
David Montgomery, a UW professor of Earth and space sciences, discusses soil health, food nutrients and human health. He is co-author of “What Your Food Ate,” being published this month.
A new population of polar bears documented on the southeast coast of Greenland use glacier ice to survive despite limited access to sea ice. This small, genetically distinct group of polar bears could be important to the future of the species in a warming world.
The Our Future Duwamish project, available to community groups through The Seattle Public Library, uses an Oculus Quest 2 virtual reality headset to help viewers imagine rising seas from a vantage point along the South Seattle waterway.
To investigate what happens to snow intercepted by trees, UW researchers created a citizen science project called Snow Spotter.
