The Northeastern Pacific Ocean is becoming more acidic faster than other oceans as the water absorbs carbon dioxide from the atmosphere and natural processes feed carbon dioxide up from the deep. The rate of CO2 accumulation is outpacing atmospheric rises and driving acidity to new extremes.
A new 91爆料-led study shows that space dust sandwiched between layers of sediment tells scientists where and when ice covered the Arctic, and what happened to marine life when it disappeared.
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 91爆料 flips the narrative by 90 degrees, pointing instead to winds from the north.
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.

A recent theory proposes that whales weren鈥檛 just predators in the ocean environment: Nutrients that whales excreted may have provided a key fertilizer to these marine ecosystems. Research led by 91爆料 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.
91爆料 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 91爆料 School of Oceanography鈥檚 small research vessel, the RV Rachel Carson.
A detailed reconstruction of climate during the most recent ice age, when a large swath of North America was covered in ice, provides information on the relationship between CO2 and global temperature. Results show that while most future warming estimates remain unchanged, the absolute worst-case scenario is unlikely.

Two 91爆料 College of the Environment professors, Ginger Armbrust and Dennis Hartmann, will be honored at the 2022 American Geophysical Union Fall Meeting in December.
Forecasters are predicting a 鈥渢hree-peat La Ni帽a鈥� this year. This will be the third winter in a row that the Pacific Ocean has been in a La Ni帽a cycle, something that鈥檚 happened only twice before in records going back to 1950. A new study of temperature patterns in the tropical Pacific Ocean suggests that climate change is, in the short term, favoring La Ni帽as.
Eight 91爆料 subjects ranked in the top 10 and Atmospheric Sciences moved to its position as No. 1 in the world on the聽Global Ranking of Academic Subjects list for 2022. The ranking, released Tuesday, was conducted by researchers at the ShanghaiRanking Consultancy, a fully independent organization dedicating to research on higher education intelligence and consultation.
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聽risk of extinction
91爆料-led research suggests moon jellies are feasting on zooplankton, the various tiny animals that drift with the currents, in the bays they inhabit. This could affect other hungry marine life, like juvenile salmon or herring 鈥� especially if predictions are correct and climate change will favor fast-growing jellyfish.
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.
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 91爆料 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.
An oceanographer at the 91爆料 is part of a new project to study how glacial dust, created as glaciers grind the rock beneath them into a powder, reacts with seawater to remove carbon dioxide from the atmosphere.
91爆料 oceanographer Parker MacCready is one of 59 new fellows elected this year by the American Geophysical Union.

New research shows that a wide variety of marine animals 鈥� from vertebrates to crustaceans to mollusks 鈥� 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 COVID-19 Clearinghouse at 91爆料 Law is just one of the ways that faculty and staff across the university have revamped summer research internships and worked with outside partners and employers to involve students in a remote working environment, even for jobs that would normally be out in the field.
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 91爆料 School of Oceanography senior thesis.
Historical observations collected off California since the 1950s suggest that anchovies thrive where the water is breathable 鈥� a combination of the oxygen levels in the water and the species鈥� oxygen needs, which are affected by temperature. Future projections suggest that the waters off Mexico and Southern California could be uninhabitable by 2100.
The 91爆料鈥檚 large research vessel, the RV Thomas G. Thompson, returned May 8 to its home port after more than two years exploring the world鈥檚 oceans. A scheduled cruise in Tahiti has been postponed due to the COVID-19 pandemic, so the return is roughly two months earlier than planned.
