P. Dee Boersma, a UW professor of biology and director of the Center for Ecosystem Sentinels, is a finalist for the 2020 Indianapolis Prize for conservation, to be awarded later this year by the Indianapolis Zoological Society. Sue Moore, a scientist with the center and a UW affiliate professor of biology and of aquatic and fishery sciences, has won the 2020 IASC Medal, also known as the Arctic Medal, from the International Arctic Science Committee.

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 , 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.”

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 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…

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.

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 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.
