Northwest winter weather: El Niño, coastal effects, no more ‘blob’

Map showing precipitation forecasts

What some have called the “Godzilla El Niño” is now lumbering ashore, right on schedule. El Niño tends to influence North American weather after the first of January, and indeed, we’re seeing warm temperatures in Alaska and much-needed rain in California. University of Washington researchers are tracking what the season will deliver to the Pacific…

person standing in mud

The large, fast-moving mudslide that buried much of Oso, Washington in March 2014 was the deadliest landslide in U.S. history. Since then it’s been revealed that this area has experienced major slides before, but it’s not known how long ago they occurred. University of Washington geologists analyzed woody debris buried in earlier slides and used…

Earth, covered in ice.

It took 100 million years for oxygen levels in the oceans and atmosphere to increase to the level that allowed the explosion of animal life on Earth about 600 million years ago, according to a study co-authored by two University of Washington scientists and led by the University College London.

UW Tacoma geoscientist tracked risks from deadly 2015 Nepal earthquake

The Annapurna Massif thrones above the city of Pokhara, and has shed several cubic kilometers of earthquake debris to form the city’s foundations.

When an earthquake struck Nepal in late April 2015, thousands of lives were lost in the initial disaster. But it was hard to assess the scale of the damage to rural areas, and still lurking were threats from unstable slopes and dammed glacier-fed lakes that could dislodge at any time to flood villages below. A…

Oceans — and ocean activism — deserve broader role in climate change discussions

When President Barack Obama visited the shrinking Exit Glacier in September, he pointed to a very obvious sign of our warming planet literally at his feet. Less visible, but perhaps more indelible, signs of changing climate lie in the oceans. A University of Washington researcher argues in the journal Science that people — including world…


From garden to gut: New book from UW’s David Montgomery explores an unfolding scientific revolution

A new book by University of Washington geologist David Montgomery weaves history, science and personal challenges into an exploration of humanity’s tangled relationship with microbes, perhaps the least loved and most misunderstood creatures on Earth — and in you. “The Hidden Half of Nature: The Microbial Roots of Life and Health” comes out Nov. 16…

Gear, not geoducks, impacts ecosystem if farming increases

Geoduck clams after harvesting.

The equipment used to farm geoducks, including PVC pipes and nets, might have a greater impact on the Puget Sound food web than the addition of the clams themselves. That’s one of the findings of the first major scientific study to examine the broad, long-term ecosystem effects of geoduck aquaculture in Puget Sound.

New study uses high-speed search methods to better estimate climate threats to biodiversity

In a study published this week in the journal PLOS ONE, researchers have used new high-performance computing methods and comprehensive data on the distribution of thousands of species to map the threat that climate change poses to birds, mammals and amphibians across the Western Hemisphere. They found that although Arctic areas have experienced the most rapid warming to date, climate-related threats to the Amazon basin’s biodiversity will eclipse those in other regions by the year 2100.


Bubble plumes off Washington, Oregon suggest warmer ocean may be releasing frozen methane

Sonar image of bubbles rising from the seafloor off the Washington coast.

The location of bubble plumes off the Pacific Northwest coast supports the idea that gradual ocean warming at about a third of a mile depth may be releasing frozen methane in the seafloor, causing it to bubble up as a gas.

Student collaboration leads to first results describing sick sea star immune response

A group of young marine-disease researchers from around the country has contributed key information about sea stars’ immune response when infected with a virus that is thought to cause a deadly wasting disease. It’s the first time researchers have tracked how genes behave when encountering this naturally occurring pathogen, which could help explain how sea stars attempt to fight the virus and why they develop lesions and appear to melt.

Lab experiments question popular measure of ancient ocean temperatures

The study looked at Thaumarchaeota archaea, which are found throughout the world's oceans. These single-celled organisms have just one membrane sac that encloses their bodies. This organism, used in the study, was collected from a tropical-water tank at the Seattle Aquarium.

The membranes of sediment-entombed archaea are an increasingly popular way to determine ocean surface temperatures back to the age of the dinosaurs. But new results show that changing oxygen can affect the reading by as much as 21 degrees C.
