Explaining dramatic planetwide changes after world’s last ‘Snowball Earth’ event
Some of the most dramatic climatic events in our planet’s history are “Snowball Earth” events that happened hundreds of millions of years ago, when almost the entire planet was encased in ice up to 0.6 miles thick. New research from the University of Washington provides a more complete picture for how the last Snowball Earth event ended, and suggests why it preceded a dramatic expansion of life on Earth, including the emergence of the first animals.

Signs of life detectable in single ice grain emitted from extraterrestrial moons
Could life be found in frozen sea spray emitted from moons orbiting Saturn or Jupiter? New research finds that life can be detected in a single ice grain containing one bacterial cell or portions of a cell. The results suggest that if life similar to that on Earth exists on these planetary bodies, this life should be detectable by instruments launching in the fall.

80 mph speed record for glacier fracture helps reveal the physics of ice sheet collapse
New research documents the fastest-known large-scale breakage along an Antarctic ice shelf. In 2012, a 6.5-mile crack formed in about 5 and a half minutes, showing that ice shelves can effectively shatter, though the speed of breakage is reduced by seawater rushing in. These results can help improve ice-sheet models and projections for future sea level rise.

Q&A: How ‘slow slip’ earthquakes may be driven by deep hydraulic fracturing
New research confirms the cause of slow slip along the Cascadia Subduction Zone and other faults that is accompanied by intermittent tremors or “pops” at the surface. Co-authors Marine Denolle and Joan Gomberg discuss the role of fluid-driven fracturing deep underground.

Shallow soda lakes show promise as cradles of life on Earth
Field observations from an unusual lake show that in environments known as “soda lakes” phosphate can concentrate at the very high levels needed for the basic molecules of life to emerge. A shallow, salty lake in western Canada gives new support to Charles Darwin’s idea that life could have emerged in a “warm little pond.”

Newly discovered form of salty ice could exist on surface of extraterrestrial moons
Scientists suspect that the red streaks crossing the surface of Jupiter’s moon Europa is a frozen mixture of water and salts, but its chemical signature matches no known substance on Earth. Now researchers have discovered a new type of solid crystal that forms when water and table salt combine in cold, pressurized conditions. Researchers believe the new substance created in a lab on Earth could form at the surface and bottom of these worlds’ deep oceans.

UW brings field geology to students with ‘Virtual Field Geology’
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 “dry run” experiences; and to allow scientific collaborators to do virtual visits to a field site together. While the pandemic brought new urgency to the project, its developers believe it’s part of a “new normal” for geology research and education.

Deepest scientific ocean drilling effort sheds light on Japan’s next ‘big one’
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.

New study calculates retreat of glacier edges in Alaska’s Kenai Fjords National Park
As glaciers worldwide retreat due to climate change, managers of national parks need to know what’s on the horizon to prepare for the future. A new study from the University of Washington 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.

Farms following soil-friendly practices grow healthier food, study suggests
An experiment conducted on 10 farms across the U.S. suggests that crops from farms following soil-friendly practices for at least five years have a healthier nutritional profile than the same crops grown on neighboring, conventional farms. Researchers believe soil microbes and fungi boost certain beneficial minerals, vitamins and phytochemicals in the crops.

Glaciers are squishy, holding slightly more ice than thought
Though usually though of as a solid, glaciers are also slightly compressible, or squishy. This compression over the huge expanse of an ice sheet — like Antarctica or Greenland — makes the overall ice sheet more dense and lowers the surface by tens of feet compared to what would otherwise be expected.

Simulations show how earthquake early warning might be improved for magnitude-9 earthquakes
Seismologists used 30 detailed simulations of magnitude-9 slips on the Cascadia Subduction Zone to evaluate how the ShakeAlert earthquake early warning system would perform in these events. Results show the alerts generally work well, but suggest that lower alert thresholds provide more timely warnings over the full area that will feel the shaking.

Volcanic eruptions may have spurred first ‘whiffs’ of oxygen in Earth’s atmosphere
A new analysis of 2.5-billion-year-old rocks from Australia finds that volcanic eruptions may have stimulated population surges of marine microorganisms, creating the first puffs of oxygen into the atmosphere. This would change existing stories of Earth’s early atmosphere, which assumed that most changes in the early atmosphere were controlled by geologic or chemical processes.

Video: A visit to Mt. Baker’s Easton Glacier
This week, a few members of our UW News team joined glaciologists from the UW Department of Earth & Space Sciences on a trip to Mt. Baker. Students that came along got to chat with their professor on the hike up, and we learned about how the recent heat wave impacted the snow melt on the ice.

Edge of Pine Island Glacier’s ice shelf is ripping apart, causing key Antarctic glacier to gain speed
Satellite images show that from 2017 to 2020, Pine Island Glacier’s ice shelf lost about one-fifth of its area, mostly in three dramatic breaks. This caused the glacier to speed up by 12%, hastening its downward motion and boosting its contribution to rising seas.

UW launches GeoHazards Initiative; names Paros Chair in Seismology and GeoHazards
Leveraging the tectonic laboratory of the Cascadia subduction zone, the University of Washington today announced a new effort to best understand how to study and live with the threats of earthquakes, tsunamis, volcanos, landslides and other seismic hazards. Dubbed the GeoHazards Initiative, the interdisciplinary work aims to develop and promote the adoption of early detection systems both on land and at sea to help prevent the loss of human life and property.

Deep earthquakes within the Juan de Fuca plate produce few aftershocks
In the Cascadia subduction zone, medium- and large-sized “intraslab” earthquakes, in which the slip happens within the oceanic plate and below the continental plate, will likely produce only a few detectable aftershocks, according to a new study from the University of Washington and the U.S. Geological Survey.

Warming temperatures tripled Arctic lightning strikes over the past decade
Lightning strikes in the Arctic tripled from 2010 to 2020, a finding University of Washington researchers attribute to rising temperatures due to human-caused climate change. The results, researchers say, suggest Arctic residents in northern Russia, Canada, Europe and Alaska need to prepare for the danger of more frequent lightning strikes.
