Bubbles of methane rising from seafloor in Puget Sound

Two researchers stand on the R/V Carson

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.

In recent years, environmental challenges, like climate change, have become a critical focus point of scientists worldwide. Researchers work tirelessly to ask and examine questions that deal with the very future of our world. Taking a closer look, we find that some of the voices answering those questions have a particular essence. Hispanic scientists have taken up the challenge to push forward environmental research to address the issues that ultimately threaten the delicate balance and even the survival of our planet’s ecosystems.

Earlier this year, the United States officially re-entered the Paris Climate Agreement, an international accord that brings many nations together to address climate change. This reconciliation puts the U.S. on track to adopt cleaner energy policies in the pursuit of eventual carbon neutrality. This return also reinforces the importance of advancing environmental research to decrease our dependence on fossil fuels, which is critical to curbing carbon dioxide emissions.

Friday Harbor Laboratories' observation system collects and shares real-time data about Salish Sea

The docks at FHL

Friday Harbor Laboratories (FHL) recently established the Friday Harbor Laboratories Ocean Observatory (FHLOO), vastly expanding their capabilities to collect and share real-time data about the surrounding marine environment. Connected to the larger Northwest Association of Networked Ocean Observing Systems (NANOOS), FHLOO takes continuous seawater measurements such as salinity, temperature, CO2, oxygen and chlorophyll, in addition to monitoring microplankton. While the system has been taking measurements since the summer of 2020, the ability to live-stream its data is new, providing a window into the Salish Sea accessible to researchers, students and the public.

Volcanic eruptions may have spurred first ‘whiffs’ of oxygen in Earth’s atmosphere

Roger Buick in 2004 at the Mount McRae Shale in Western Australia

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. Though focused on Earth’s early history, the research also has implications for extraterrestrial life and even climate change.
