Leaders are updating the laws for international waters that apply to most of the world’s ocean environment. This provides a unique opportunity, argues a UW Bothell marine scientist, to anticipate new techniques that allow protected zones to shift as species move under climate change.
When nearly one million common murres died at sea and washed ashore from California to Alaska in 2015 and 2016, it was unprecedented. Scientists from the University of Washington, the U.S. Geological Survey and others blame an unexpected squeeze on the ecosystem’s food supply, brought on by a severe and long-lasting marine heat wave known as “the blob.”
Nearly half of the fish caught worldwide are from stocks that are scientifically monitored and, on average, are increasing in abundance. Effective management appears to be the main reason these stocks are at sustainable levels or successfully rebuilding, according to a new study led by the University of Washington.
Life as we know it requires phosphorus, which is scarce. So, how did a lifeless environment on the early Earth supply this key ingredient? A new UW study, published Dec. 30 in the Proceedings of the National Academy of Sciences, finds an answer to this problem in certain types of carbonate-rich lakes.
Large, old Chinook salmon have mostly disappeared from the West Coast. A new University of Washington and NOAA study points to the recent rise of resident killer whales, and their insatiable appetite for large Chinook salmon, as the main driver behind the decline of the big fish.
An Antarctic field campaign last winter led by the U.S. and Australia has successfully extracted some of the largest samples of air dating from the 1870s until today. Researchers will use the samples to look for changes in the molecules that scrub the atmosphere of methane and other gases.
To better understand large, disruptive snowstorms, a University of Washington atmospheric scientist will lead a NASA field campaign this winter to fly through major snowstorms along the East Coast. The multi-institutional team will observe snow as it forms in clouds to help with satellite monitoring of snowfall and ultimately improve forecasts.
With 2019 on pace as one of the warmest years on record, a new international study reveals how rapidly the Arctic is warming and examines global consequences of continued polar warming.
Researchers from the University of Washington and Michigan Technological University have created the first comprehensive database of all the wildfire fuels that have been measured across North America. Ultimately, it can help scientists make more informed decisions about fire and smoke situations.
Communities underneath and downwind of jets landing at Seattle-Tacoma International Airport are exposed to a type of ultrafine particle pollution that is distinctly associated with aircraft, according to a new University of Washington study, the first to identify the unique signature of aircraft emissions in the state of Washington. The finding comes from the two-year Mobile ObserVations of Ultrafine Particles or “MOV-UP” study funded by the Washington State Legislature to examine the air-quality impacts of aircraft traffic on communities located…
A new experiment by the University of Washington has found that some corals are more likely to eat microplastics when they are consuming other food, yet microplastics alone are undesirable.
The American Association for the Advancement of Science has named six faculty members from the University of Washington as AAAS Fellows, according to a Nov. 26 announcement. They are part of a cohort of 443 new fellows for 2019, all chosen by their peers for “scientifically or socially distinguished efforts to advance science or its applications.”
UW researchers have found that air pollution from electricity generation emissions in 2014 led to about 16,000 premature deaths in the continental U.S. In many states, the majority of the health impacts came from emissions originating in other states.
A University of Washington team is leaving to study how fall storms, dwindling sea ice and vulnerable coastlines might combine in a changing Arctic.
UW marine scientists are using high-tech tags to record the movements of swordfish — big, deep-water, migratory, open-ocean fish that are poorly studied — and get a window into the ocean depths they inhabit.
After years of preparation, a tiny satellite built by UW students is scheduled to launch early Saturday, Nov. 2, from a NASA flight facility in Virginia. The launch will be broadcast live on NASA TV.
A team led by the University of Washington and Stanford University has discovered clues in the environment that help identify transmission hotspots for schistosomiasis, a parasitic disease that is second only to malaria in its global health impact.
This week a UW team is releasing a robotic surfboard to explore the surface ocean around Antarctica.
A new study finds that the western South Atlantic humpback population has grown to 25,000 whales. Researchers, including co-authors from the University of Washington, believe this new estimate is now close to pre-whaling numbers.
A team led by the University of Washington has developed a way to help foresters predict which nonnative insect invasions will be problematic, and help managers decide where to allocate resources to avoid widespread tree death.
With the help of new technologies, a team led by the University of Washington has confirmed that piranhas — and their plant-eating cousins, pacus — lose and regrow all the teeth on one side of their face multiple times throughout their lives. How they do it may help explain why the fish go to such efforts to replace their teeth.
In a new study, an interdisciplinary group of researchers used Pacific herring in Haida Gwaii, British Columbia, as a case study for modeling the implicit tradeoffs within the triple bottom line that result from various fisheries management decisions.
The University of Washington’s Abigail Swann is honored by Science News on its list of 10 promising early- and mid-career scientists.
A University of Washington team inspired by the clingfish’s suction power set out to develop an artificial suction cup that borrows from nature’s design. Their prototype actually performed better than the clingfish.
This fall the University of Washington’s annual engineering lecture series will feature three UW engineers and scientists who are working across disciplines to manage the quality and quantity of the food we eat and grow.
Millions of people are suffering from malnutrition despite some of the most nutritious fish species in the world being caught near their homes, according to new research published Sept. 25 in Nature.
Two UW researchers — Bonnie Light, a principal physicist at the UW’s Applied Physics Laboratory and an affiliate associate professor of atmospheric sciences, and Madison Smith, a recent UW graduate who is now doing her postdoctoral research at the UW — will join for the fifth of the six two-month legs, in summer 2020.
Researchers at the University of Washington and the University of Strathclyde report that, in Willapa Bay in Washington state, the water washing over the tidal flats during high tides is largely the same water that washed over the flats during the previous high tide. This “old” water has not been mixed in with “new” water from deeper parts of the bay or the open Pacific Ocean, and has different chemical and biological properties, such as lower levels of food for creatures within the tide flats.
A study of superbolts, which release a thousand times more electrical energy in the low-frequency range than regular lightning bolts, finds they occur at very different times and places than regular lightning. Superbolts tend to strike over particular parts of the oceans, while regular lightning strikes over land.
UW oceanographers used lab experiments and seawater samples to learn how photosynthetic microbes and ocean bacteria use sulfur, a plentiful marine nutrient.
More than 99 percent of wildfires in the last 40 years have been east of the Cascade Crest. But evidence that suggests Western Washington also has a history of large wildfires, each burning hundreds of thousands of acres. We might not be familiar with them, because most happened centuries ago.
Three University of Washington graduate students are among this year’s recipients of a prestigious NASA fellowship that funds student research projects in the fields of Earth and planetary sciences and astrophysics.
The U.S. Geological Survey announced $10.4 million in funding to the Pacific Northwest Seismic Network, based at University of Washington, to support the ShakeAlert earthquake early warning system. Some $7.3 million of the two-year funding total will go to the UW.
Air pollution—especially ozone air pollution which is increasing with climate change—accelerates the progression of emphysema of the lung, according to a new study led by the University of Washington, Columbia University and the University at Buffalo.
A new study by U.S. and U.K. scientists finds that in addition to natural variations in winds that drive warmer water to the West Antarctic Ice Sheet, which last about a decade, there has been a longer-term change in the winds that can be linked with human activities.
A new study provides a 110-year record of the total volume of Arctic sea ice, using early U.S. ships’ voyages to verify the earlier part of the record. The longer record puts the recent loss into perspective.
Analyzing the full life cycle of long-term droughts and how they relate to El Niño and La Niña conditions in the Pacific Ocean could eventually lead to better prediction of damaging, multiyear droughts in the Southwestern U.S.
An international team led by the UW and Stanford has created a framework for how city planners and municipalities around the world can start to measure the mental health benefits of nature and incorporate those into plans and policies for cities and their residents.
After more than 20 years, the UW’s Coastal Observation and Seabird Survey Team, or COASST, is itself the subject of scientific study. Social scientists are studying the program’s success to extract lessons for all citizen science efforts.
