UW Department of Atmospheric Sciences maintains No. 1 global ranking; more than two dozen UW subjects in top 50
Six University of Washington subjects ranked in the top 10, and atmospheric sciences maintained its position as No. 1 in the world on the Global Ranking of Academic Subjects list for 2023. The ranking, released at the end of October, was conducted by researchers at the ShanghaiRanking Consultancy, a fully independent organization dedicated to research on higher education intelligence and consultation.
North Atlantic’s marine productivity may not be declining, according to new study of older ice cores
To paraphrase Mark Twain, reports of declining phytoplankton in the North Atlantic may have been greatly exaggerated. Analysis of a Greenland ice core going back 800 years shows that atmospheric chemistry, not dwindling phytoplankton populations, explains the recent ice core trends.

Polar experiments reveal seasonal cycle in Antarctic sea ice algae
The frigid ocean surrounding Antarctica is home to much of the region’s photosynthetic life. A new University of Washington study provides the first measurements of how sea-ice algae and other single-celled life handle dramatic seasonal swings, offering clues to how this ecosystem might adapt to climate change.

Unchecked global emissions on track to initiate mass extinction of marine life
If emissions from greenhouse gases continue, species losses from warming and oxygen depletion of ocean waters could eclipse all other human stressors on marine species by around 2100. Tropical waters would experience the greatest loss of biodiversity, while polar species are at the highest risk of extinction

Solar energy explains fast yearly retreat of Antarctica’s sea ice
Sea ice around Antarctica retreats more quickly than it advances, an asymmetry that has been a puzzle. New analysis shows that the Southern Hemisphere is following simple rules of physics, as peak midsummer sun causes rapid changes. In this respect, it seems, it’s Arctic sea ice that is more mysterious.

Shift work helps marine microbes share scarce ocean resources
With a low supply of and high competition for key nutrients, scientists have puzzled over the vast diversity of microbial species found in the open ocean. A new study shows that time of day is key, with species of marine microbes specializing in different shifts throughout the day and night.

Bubbles of methane rising from seafloor in Puget Sound
The release of methane, a powerful greenhouse gas responsible for almost a quarter of global warming, is being studied around the world, from Arctic wetlands to livestock feedlots. A University of Washington team has discovered a source much closer to home: 349 plumes of methane gas bubbling up from the seafloor in Puget Sound, which holds more water than any other U.S. estuary.

How Dungeness crabs’ complex lifecycle will be affected by climate change
Results show that by the end of this century, lower-oxygen water on the Pacific Northwest coast will pose the biggest threat to Dungeness crabs. And while these crabs start as tiny, free-floating larvae, it’s the sharp-clawed adults that will be most vulnerable.

Remotely-piloted sailboats monitor ‘cold pools’ in tropical environments
A UW-led study uses data from remotely-piloted sailboats to better understand cold air pools — pockets of cooler air that form when rain evaporates below tropical storm clouds. These fleeting weather phenomena are thought to influence tropical weather patterns.

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.

Marine organisms use previously undiscovered receptors to detect, respond to light
Single-celled organisms in the open ocean use a diverse array of genetic tools to detect sunlight, even in tiny amounts, and respond. The discovery of these new genetic “light switches” could also aid in the field of optogenetics, in which a cell’s function can be controlled with light exposure.

Warm oceans helped first human migration from Asia to North America
New research reveals significant changes to the circulation of the North Pacific and its impact on the initial migration of humans from Asia to North America. It provides a new picture of the circulation and climate of the North Pacific at the end of the last ice age, with implications for early human migration.

Marine animals live where ocean is most ‘breathable,’ but ranges could shrink with climate change
New research shows that a wide variety of marine animals — from vertebrates to crustaceans to mollusks — already inhabit the maximum range of breathable ocean that their physiology will allow. The findings provide a warning about climate change: Since warmer waters will harbor less oxygen, some stretches of ocean that are breathable today for a given species may not be in the future.

The most common organism in the oceans harbors a virus in its DNA
A new study in Nature Microbiology shows that the most common organism in the world’s oceans — and possibly the whole planet — harbors a virus in its DNA. This virus may have helped it survive and outcompete other organisms. The study began as a UW School of Oceanography senior thesis.

Ocean ‘breathability’ key to past, future habitat of West Coast marine species
Historical observations collected off California since the 1950s suggest that anchovies thrive where the water is breathable — a combination of the oxygen levels in the water and the species’ oxygen needs, which are affected by temperature. Future projections suggest that the waters off Mexico and Southern California could be uninhabitable by 2100.

Video: Warming Arctic means less ice, bigger waves
Throughout the month of November 2019, a team of University of Washington researchers chased storms in the Arctic Ocean. The project, Coastal Ocean Dynamics in the Arctic, or CODA, is looking at how water currents shift and waves hit the coast with more open water, to provide better forecasts and predictions for the region’s future.

Mobile protected areas needed to preserve biodiversity in the high seas
Leaders are updating the laws for international waters that apply to most of the world’s ocean environment. This provides a unique opportunity, argues a UW Bothell marine scientist, to anticipate new techniques that allow protected zones to shift as species move under climate change.

Tides don’t always flush water out to sea, study shows
Researchers at the University of Washington and the University of Strathclyde report that, in Willapa Bay in Washington state, the water washing over the tidal flats during high tides is largely the same water that washed over the flats during the previous high tide. This “old” water has not been mixed in with “new” water from deeper parts of the bay or the open Pacific Ocean, and has different chemical and biological properties, such as lower levels of food for creatures within the tide flats.

Super salty, subzero Arctic water provides peek at possible life on other planets
A UW team has discovered thriving communities of bacteria in Alaskan “cryopegs,” trapped layers of sediment with water so salty that it remains liquid at below-freezing temperatures. The setting may be similar to environments on Mars, Saturn’s moon Titan, or other bodies farther from the sun.
