A 91探花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.
Why did a giant hole appear in the sea ice off Antarctica in 2016 and 2017, after decades of more typical sea ice cover? Years of Southern Ocean data have explained the phenomenon, helping oceanographers to better predict these features and study their role in global ocean cycles.
In oxygen-poor parts of the ocean, some microorganisms survive by breathing arsenic. This holdover from the ancient Earth was not thought to still exist in the open ocean.
Families, students and children are invited to get their hands wet on Saturday with 鈥淥ur Watery World,鈥� the 91探花鈥檚 second annual aquatic science open house.

The 91探花is part of an international program that has revolutionized ocean measurements. This fall, the program made its 2 millionth measurement, reporting temperature and salinity in the top mile of the world’s oceans.
New research from the 91探花 and Stanford University combines models of ocean conditions and animal metabolism with published lab data and paleoceanographic records to show that the Permian mass extinction in the oceans was caused by global warming that left animals unable to breathe. As temperatures rose and the metabolism of marine animals sped up, the warmer waters could not hold enough oxygen for them to survive.
91探花oceanographer Jody Deming is a leader of a new, interdisciplinary effort that addresses the theme of “ocean memory.”
The National Science Foundation will support a state-of-the-art marine facility that continues delivering data and new insight to the ocean science community, policymakers and the public worldwide.
Two 91探花polar scientists were among a dozen experts who advised NASA on its upcoming ICESat-2 mission to monitor the 3D surface of the Earth. The mission is scheduled to launch Sept. 15 from California.
In a paper published Aug. 31 in the journal Science, a team led by scientists at the 91探花 reports that insect activity in today’s temperate, crop-growing regions will rise along with temperatures. Researchers project that this activity, in turn, will boost worldwide losses of rice, corn and wheat by 10-25 percent for each degree Celsius that global mean surface temperatures rise.
A new study led by the 91探花 uses data gathered by floating drones in the Southern Ocean over past winters to learn how much carbon dioxide is transferred by the surrounding seas. Results show that in winter the open water nearest the sea ice surrounding Antarctica releases significantly more carbon dioxide than previously believed.
More than 100 scientists and crew from more than 20 U.S. research institutions, including the UW, will depart in August for a month-long expedition to study how the ocean absorbs carbon from the atmosphere.
The 91探花School of Oceanography has a new vessel, named after marine biologist, author and conservationist Rachel Carson. It will explore Puget Sound and nearby coasts.
Oceanographer Cecilia Peralta Ferriz is spending the academic year in Troms酶, Norway, to collaborate with colleagues who study flow out of the Arctic Ocean.
Bowhead whales are constantly changing their tune, unlike the only other whale species that sings, the humpback.
After an “extreme makeover” that went from stem to stern on five decks of the ship, the R/V Thomas G. Thompson is ready to get back to work exploring the world’s oceans. The 91探花’s School of Oceanography, part of the College of the Environment, operates the 274-foot ship, which arrived on campus in 1991. In summer 2016, with funding from the U.S. Office of Naval Research, the National Science Foundation and the UW, the vessel headed to a…
An experiment using hundreds of plastic drifters in the Gulf of Mexico shows that rather than simply spread out, as current calculations would predict, many of them clumped together in a tight cluster.
A new study in the Journal PLOS ONE details what removing the two dams on the Elwha River meant for the nearshore marine ecosystem.
A new partnership between the 91探花and Paul G. Allen Philanthropies will use a network of robots to observe conditions beneath a floating Antarctic ice shelf.
91探花 oceanographers are working with a local company to develop a simple new technique that could track seafloor movement in earthquake-prone coastal areas.
The National Science Foundation is funding the largest marine seismic-monitoring effort yet along the Alaska Peninsula, a region with frequent and diverse earthquake and volcanic activity. Involving aircraft and ships, the new Alaska Amphibious Community Seismic Experiment will be led by Cornell University in Ithaca, New York, with partners at the 91探花 and seven other research institutions. “This effort will really change the information we have at our disposal for understanding the seismic properties of subduction zones,” said…
The annual maintenance cruise for the Pacific Northwest’s deep-sea observatory continues through Aug. 29. Two dozen students will participate, and more than 120 ocean instruments will get their yearly checkup.
Oceanographers are building swimming robots to carry out an ambitious mission gathering climate data from one of Earth’s most challenging locations: the icy water that surrounds Antarctica.
A 91探花undergraduate in oceanography sampled tiny pieces of plastic on 12 Puget Sound beaches. She found that plastic fragments are widespread, and include some surprising sources.
New 91探花 research finds large earthquakes can trigger underwater landslides thousands of miles away, weeks or months after the quake occurs.
New analysis debunks reports that recent observations are showing that Earth’s temperature responds less to greenhouse gases than predicted by climate models.
Vitamin B-12 exists in two different, incompatible forms in the oceans. An organism thought to supply the essential vitamin B-12 in the marine environment is actually churning out a knockoff version.
Autonomous floating sensors built at the 91探花are being deployed to track conditions in the waters surrounding Antarctica.
The cracking, bulging and shaking from the eruption of a mile-high volcano where two tectonic plates separate has been captured in more detail than ever before. A 91探花 study published this week shows how the volcano behaved during its spring 2015 eruption, revealing new clues about the behavior of volcanoes where two ocean plates are moving apart. “The new network allowed us to see in incredible detail where the faults are, and which were active during the eruption,”…
Oceanographers used tools developed for semiconductor research to view the formation of a marine shell in the most detail yet, to understand how organisms turn seawater into solid mineral.
Unlike in the movies, and in some theories of climate change, the recent slowdown of Atlantic Ocean circulation is not connected with the melting of the Arctic sea ice. Instead, it seems to be connected to shifts around the southern tip of Africa.
91探花oceanographers are working on a system that will act like a ‘weather forecast’ for Pacific Northwest harmful algal blooms.
Charles Eriksen, Deborah Kelley and Stephen Warren are among 60 newly elected fellows from U.S. and international institutions.
Polar oceans pump organic carbon down to the deep sea about five times as efficiently as subtropical waters, because they can support larger, heavier organisms. The finding helps explain how the oceans may function under climate change.
A 91探花 team has shed new light on a common but poorly understood bacteria known to live in low-oxygen areas in the ocean. By culturing and sequencing the microbe’s entire genome, the oceanographers found that it significantly contributes to the removal of life-supporting nitrogen from the water in new and surprising ways.
The R/V Thomas G. Thompson, the 274-foot-long research vessel operated by the 91探花, has spent 25 years carrying researchers, students and teachers out to sea. The ship has collected material from the bottom of the deepest ocean trenches and braved storms near Antarctica. This week, the ship will begin a yearlong stay in protected waters and dry dock near Seattle’s Harbor Island for a complete overhaul of its propulsion system, navigation and many core engineering systems. The $34.5…
Data is now streaming from the deep sea, thanks to an observatory installed in this region by the 91探花 as part of a larger National Science Foundation initiative to usher in a new age of oceanographic research.
