Signals from the ionosphere could improve tsunami forecasts

Research from the University of Washington shows that signals from the upper atmosphere could improve tsunami forecasting and, someday, help track ash plumes and other impacts after a volcanic eruption. A new study analyzed the Hunga Tonga-Hunga Ha’apai eruption in the South Pacific earlier this year. The Jan. 15, 2022, volcanic eruption was the largest to be recorded by modern equipment.

UW brings field geology to students with ‘Virtual Field Geology’

Whaleback anticline

University of Washington geologists had set out to create computer-based field experiences long before the COVID-19 pandemic hit. Juliet Crider, a UW associate professor of Earth and space sciences, first got a grant from the National Science Foundation to send a former graduate student and a drone to photograph an iconic Pennsylvania geological site and pilot a new approach to field geology.

Strongest Arctic cyclone on record led to surprising loss of sea ice

A ship-based view of the Arctic Ocean where the ocean surface is starting to freeze.

A warming climate is causing a decline in sea ice in the Arctic Ocean, where loss of sea ice has important ecological, economic and climate impacts. On top of this long-term shift due to climate change are weather events that affect the sea ice from week to week. The strongest Arctic cyclone ever observed poleward of 70 degrees north latitude struck in January 2022 northeast of Greenland.

Study reveals how ancient fish colonized the deep sea

The deep sea contains more than 90% of the water in our oceans, but only about a third of all fish species. Scientists have long thought the explanation for this was intuitive — shallow ocean waters are warm and full of resources, making them a prime location for new species to evolve and thrive. But a new University of Washington study led by Elizabeth Miller reports that throughout Earth’s ancient history, there were several periods of time when many fish actually favored the cold, dark, barren waters of the deep sea.

Permanent daylight saving time would reduce deer-vehicle collisions, study shows

Deer along a highway

In much of the United States, there is a twice-yearly shift in timekeeping between standard time and daylight saving time, or DST, which delays both sunrise and sunset to make mornings darker and evenings brighter. Recently, scientists, policy experts, lawmakers and citizens have debated abandoning the twice-a-year switch and adopting either year-round standard time or DST. A team of researchers at the University of Washington — led by postdoctoral researcher Calum Cunningham and Laura Prugh, an associate professor of quantitative wildlife sciences — have found that one of those options would sharply reduce a hazard common to much of the country: deer-vehicle collisions.
