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.

Drier, warmer night air is making some Western wildfires more active at night
Firefighters have reported that Western wildfires are starting earlier in the morning and dying down later at night, hampering their ability to recover and regroup before the next day’s flareup. A study by University of Washington and U.S. Forest Service scientists shows why: The drying power of nighttime air over much of the Western U.S. has increased dramatically in the past 40 years.

Air pollution from wildfires impacts ability to observe birds
Researchers from the University of Washington provide a first look at the probability of observing common birds as air pollution worsens during wildfire seasons. They found that smoke affected the ability to detect more than a third of the bird species studied in Washington state over a four-year period. Sometimes smoke made it harder to observe birds, while other species were actually easier to detect when smoke was present.

Ice core data show why, despite lower sulfur emissions in U.S. and Western Europe, air pollution is dropping more slowly
Ice core data from Greenland shows why air pollution is dropping more slowly than sulfur emissions reductions. As cloud droplets become less acidic, the chemical reaction that turns sulfur dioxide into sulfate aerosol gets more efficient. The new results can improve the models that project air quality and climate change.

Record-high Arctic freshwater will flow through Canadian waters, affecting marine environment and Atlantic ocean currents
The Arctic Ocean’s Beaufort Sea has increased its freshwater content by 40% over the past two decades. When conditions change this freshwater will travel to the Labrador Sea off Canada, rather than through the wider marine passageways that connect to seas in Northern Europe. This has implications for local marine environments and global ocean circulation.

Logging change in Puget Sound: Researchers use UW vessel logbooks to reconstruct historical groundfish populations
To understand how Puget Sound has changed, we first must understand how it used to be. But unlike most major estuaries in the U.S., long-term monitoring of Puget Sound fish populations did not exist until 1990. Now researchers have discovered an unconventional method to help fill in gaps in the data: old vessel logbooks.
