Longer body size means more female calves for baleen whale moms
University of Washington researchers found, in historical whaling data, that longer baleen whale mothers were more likely to birth female calves than males. These results run contrary to a leading evolutionary theory that suggests that fit mothers will benefit more from male offspring.

Researchers find key to Antarctic ice loss blowing in the north wind
Antarctic ice is melting at a startling pace, and the West Antarctic Ice Sheet is one of the greatest sources of uncertainty in climate projections. Researchers thought westerly winds were accelerating ice loss, but a new study from UW flips the narrative by 90 degrees, pointing instead to winds from the north.

Ocean warming puts vital marine microbe at risk
Prochlorococcus, the most abundant photosynthesizing organism in the ocean, might be more vulnerable to climate change than researchers thought. Population decline could weaken the foundation of subtropical and tropical ecosystems as ocean temperatures continue to rise.

This common fish has an uncommon feature: Forehead teeth, used for mating
New findings call into question one of the core assumptions about teeth. Adult male spotted ratfish, a shark-like species native to the eastern Pacific Ocean, have rows of teeth on top of their heads, lining a cartilaginous appendage called the tenaculum, in addition to those in their jaws. They used their tenaculum teeth to grip females while mating in water.

How oxygen made the deep ocean home to animals, spurring rapid evolution
New research shows that deep-ocean oxygenation occurred 100 million years later than previously thought, aligning with the growth and spread of land plants. Once oxygenated, the ocean hosted rapid animal evolution, leading to the rise of modern vertebrates.

‘Revolutionary’ seafloor fiber sensing reveals how falling ice drives glacial retreat in Greenland
A UW-led team of researchers used a fiber-optic cable to capture calving dynamics across the fjord of the Eqalorutsit Kangilliit Sermiat glacier in South Greenland. This allowed them to document — without getting too close — one of the key processes that is accelerating the rate of glacial mass loss and in turn, threatening the stability of ice sheets, with consequences for global ocean currents and local ecosystems.

Study projects that increasing wildfires in Canada and Siberia will actually slow global warming
A new University of Washington–led study projects that in the next 35 years increasing boreal fires will actually slow global warming by 12% globally and 38% in the Arctic. Because the aerosols in smoke reflect more sunlight and make clouds brighter, summer temperatures during fire season drop, leading to reduced sea ice loss and cooler winter temperatures.
Iron from coal, steel industries alters North Pacific ecosystem
The study revealed that iron released from industrial processes, such as coal combustion and steelmaking, is altering the ecosystem in the North Pacific Transition Zone, an area just north of Hawai’i that’s important for Pacific fisheries.

Atlantic Ocean current expected to undergo limited weakening with climate change, study finds
The Atlantic Meridional Overturning Circulation, or AMOC, is a system of ocean currents that plays a crucial role in regulating Earth’s climate by transporting heat from the Southern to Northern Hemisphere. Climate models have long predicted that global warming will cause the AMOC to weaken, with some projecting what amounts to a near-collapse relative to the AMOC strength in observations today. But a new study from a team of researchers that included the University of Washington shows that the AMOC is likely to weaken to a much lesser extent than current projections suggest.

Q&A: UW researchers examine mental impact of Girl Scouts’ interactions with nature
New research from the University of Washington, recently published in the Journal of Environmental Education, examined whether children’s interactions with nature that are embodied, rather than just visual, are associated with feeling connected to something beyond the self. Exploratory analyses found that participants who had embodied interactions reported a greater sense of presence in nature than those who reported only visual interactions.

Whale poop contains iron that may have helped fertilize past oceans
A recent theory proposes that whales weren’t just predators in the ocean environment: Nutrients that whales excreted may have provided a key fertilizer to these marine ecosystems. Research led by University of Washington oceanographers finds that whale excrement contains significant amounts of iron, a vital element that is often scarce in ocean ecosystems, and nontoxic forms of copper, another essential nutrient that in some forms can harm life.

Q&A: How rate of CO2 rise can affect a global ocean current
How fast the level of atmospheric carbon dioxide — and with it, the temperature — goes up matters for the ability of humans and ecosystems to adjust. A slower increase gives humans time to move away from low-lying coasts and animals time to move to new habitats. It turns out the rate of that increase matters for non-living systems, too. Camille Hankel, a postdoctoral researcher at the Cooperative Institute for Climate, Ocean and Ecosystem Studies, talks about her research on the Atlantic Ocean circulation.

UW oceanographer Robert Morris and a collaborator at UCLA are going out with students to collect the most abundant bacteria in the oceans to understand how its relationship with marine viruses changes depending on the place or the season. They leave Dec. 16 aboard UW School of Oceanography’s small research vessel, the RV Rachel Carson.

Surveys show full scale of massive die-off of common murres following the ‘warm blob’ in the Pacific Ocean
Colony surveys of common murres, an Alaskan seabird, show the full effects of the 2014-16 marine heat wave known as “the blob.” Analysis of 13 colonies surveyed between 2008 and 2022 finds that colony size in the Gulf of Alaska dropped by half after the marine heat wave. In colonies along the eastern Bering Sea, west of the peninsula, the decline was even steeper, at 75% loss. No recovery has yet been seen.

Record-low Antarctic sea ice can be explained and forecast months out by patterns in winds
University of Washington researchers show that the all-time record low in winter sea ice extent in 2023 can be explained by warm Southern Ocean conditions and patterns in the winds that circled Antarctica months earlier, allowing forecasts for sea ice coverage around the South Pole to be generated six or more months in advance. This could support regional and global weather and climate models.

What’s for dinner? Scientists unearth key clues to cuisine of resident killer whales
Scientists have discovered the cuisine preferences of two resident killer whale populations, also known as orcas: the Alaska residents and the southern residents, which reside primarily in the Salish Sea and off the coast of Washington, British Columbia, Oregon and northern California. The two populations show broad preference for salmon, particularly Chinook, chum and coho. But they differ in when they switch to hunting and eating different salmon species, as well as the other fish species they pursue to supplement their diets. This information could aid conservation efforts for southern resident killer whales, which remain critically endangered due to pollution, loss of salmon habitat and other human-caused factors that disrupt their hunting and reproductive capabilities.

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.

Wolves’ return has had only small impact on deer populations in NE Washington, study shows
Wolves returned to Washington state in 2008. A new study shows that, despite their rising numbers, wolves are not having much of an impact on white-tailed deer, one of their primary prey. In a paper published June 18 in Ecological Applications, scientists from the University of Washington and the Washington Department of Fish & Wildlife report that the biggest factor shaping white-tailed deer populations in northeast Washington is the quality of habitat available, which is largely determined by human activity. Cougars were second in their impact. Wolves were a distant third.
