New Study Provides First Comprehensive Look at Oxygen Loss on Coral Reefs

March 16, 2023

A new study is providing an unprecedented examination of oxygen loss on coral reefs around the globe under ocean warming. Led by researchers at UC San Diego's Scripps Institution of Oceanography, the study captures the current state of hypoxia—or low oxygen levels—at 32 different sites.

New Study Examines Noise Reduction from Retrofitted Shipping Vessels

March 16, 2023

Researchers with the Scripps Whale Acoustics Lab teamed up with shipping giant Maersk to examine radiated noise from 12 of Maersk’s retrofitted vessels, an effort to identify whether design changes have an impact on noise levels. The study was published March 16 in the journal PLOS One.

“Denoising” a Noisy Ocean

March 15, 2023

UC San Diego scientists and colleagues have developed a way for computers to sift through sounds collected by field acoustic recording packages and process them faster than even the most trained human analysts. The method represents a major advance in the field of signal processing.

Researchers Extract First Layered Lake-Sediment Sample from Subglacial Antarctica

March 9, 2023

For the first time, a team of researchers with the National Science Foundation-funded project Subglacial Antarctic Lakes Scientific Access (SALSA) has successfully extracted layered sediments from beneath the modern Antarctic ice sheet.

Complex Learned Social Behavior Discovered in Bee’s ‘Waggle Dance’

March 9, 2023

Researchers have discovered early social learning in insects. They found signaling communicated by honey bees about food sources—transmitted through a “waggle dance”—is an intricate form of social learning and one of the most complex known examples of non-human spatial referential communication.

Birch Aquarium Welcomes Baby Weedy Seadragons

March 7, 2023

Birch Aquarium at Scripps Institution of Oceanography at UC San Diego is celebrating the arrival of more than 70 tiny newborn Weedy Seadragons, which are incredibly difficult to breed and rear in captivity.

Coastal Water Pollution Transfers to the Air in Sea Spray Aerosol and Reaches People on Land

March 2, 2023

New research led by Scripps Institution of Oceanography at UC San Diego has confirmed that coastal water pollution transfers to the atmosphere in sea spray aerosol, which can reach people beyond just beachgoers, surfers, and swimmers.

Scientists and Surf Organizations Confirm What Surfers Already Know

February 28, 2023

Scientists find that offshore wind tends to encourage development of the tubular barrel waves favored by advanced surfers. “This is common surfing wisdom, but it has not been something that has been scientifically studied,” said Scripps Oceanography's Falk Feddersen, who led a new study.

Progress Toward Fast-charging Lithium-metal Batteries

February 9, 2023

Engineers report progress toward lithium-metal batteries that charge fast – as fast as an hour. This fast charging is thanks to lithium metal crystals that can be seeded and grown quickly into dense layers of uniform lithium metal that lack battery-performance-degrading spikes called dendrites.

Love Your Wetlands Day Teams Up With California Volunteers For Community Climate Action Day

February 9, 2023

California Volunteers, Office of the Governor partnered with the UC San Diego Natural Reserve System on annual Love Your Wetlands Day to promote a countywide day of service to fight climate change.
