Imaging reveals bacterial symbionts in the ovaries of tiny, aquatic crustaceans

Marine Biological Laboratory
Peer-Reviewed Publication

Researchers at the Marine Biological Laboratory (MBL) have imaged bacterial endosymbiosis inside the reproductive system of tiny crustaceans known as ostracods.The bacteria (Cardinium) are transmitted from mothers to offspring, suggesting that the bacteria manipulate host asexual reproduction. The study is published this week in Proceedings of the Royal Society B.

Narwhals hit moorings—questioning safety assumptions of oceanographic monitoring in the Arctic

Hokkaido University
Peer-Reviewed Publication

Researchers have recorded hundreds of incidents of narwhal interaction with underwater recording devices, suggesting passive monitoring is not as non-invasive as previously assumed.

Researchers uncover natural seepage of oil and gas off Northeast Greenland

Aarhus University
Peer-Reviewed Publication

New research led by Aarhus University has documented for the first time how methane and oil escape from the seafloor off northeast Greenland. The release of hydrocarbons from the seafloor affects marine ecosystems and alters the carbon cycle in the Arctic. The study by an international team of scientists clearly documents gas hydrates are present on the Northeast Greenland shelf and are now exposed to a rapidly warming Arctic Ocean.

Monk seal acoustic breakthrough: Hawai’i study quadruples known call types and detects novel communication strategy

University of Hawaii at Manoa
Peer-Reviewed Publication

In a new study, researchers from the University of Hawai'i at Mānoa analyzed thousands of hours of passive acoustic data and identified 25 distinct underwater vocalizations, a dramatic increase from the six calls previously known from seals in human care.

Diet alone doesn’t explain divergent health of California Sea Lions in US and Mexico

University of British Columbia
Peer-Reviewed Publication

Scientists compared what California sea lions eat in the Channel Islands (U.S.) and the Gulf of California (Mexico), they expected to find a clear explanation for why populations were booming in California but shrinking in Mexico. Instead, they found something more complicated.

HKUST unites international experts in CliMetS initiative to tackle climate threat of seabed methane seeps

Hong Kong University of Science and Technology
Business Announcement

The Hong Kong University of Science and Technology (HKUST) has successfully launched the Global Climate Impact of Methane Seeps (CliMetS) Initiative through a pivotal collaboration with the Southern Marine Science and Engineering Guangdong Laboratory (Guangzhou) (GML) and over 200 experts worldwide. Endorsed as a UN Ocean Decade Action, CliMetS is dedicated to mapping seabed methane seeps across the world’s oceans and quantifying their impact on global climate systems. Recently, HKUST co-led two milestone workshops in South America and Africa, galvanizing global efforts to address methane seep research gaps and fostering cross-continental partnerships.
