The Seismological Society of America will present its highest honor, the 2026 Harry Fielding Reid Medal, to Peter Shearer, professor of geophysics at Scripps Institution of Oceanography, University of California, San Diego.

Where does hydrogen in the deep sea come from? An international team led by the University of Bremen addressed this question and discovered an unexpected process occurring beneath the sparsely studied hydrothermal fields at extremely slow-spreading mid-ocean ridges that could play an important role. Particularly at sites where liquids circulate through sediments. Samples from the Jøtul Hydrothermal Field off Norway were analyzed for the study. The findings have been published in the professional journal Communications Earth & Environment.

A new study shows that allowing coral reef fish populations to recover could help fight global hunger, meeting seafood intake requirements for millions more people worldwide

Quick clay collapse can be both dangerous and costly. New research will help us understand more about why the clay is so unstable. And maybe what we can do about it.

A new study shows that coral reefs don’t just provide a home for ocean life, they also help set the daily “schedule” for tiny microbes living in the water nearby. Over the course of a single day, the quantity and types of microbes present can shift dramatically. To see this in detail, researchers took frequent water samples and used a mix of genetic and ecological methods and tools, as well as advanced imaging techniques, to track what was happening hour by hour. They found that reefs can shape microbial communities through natural interactions like grazing and predation, as well as changes in the reef’s close microbial partners. These daily ups and downs offer a fresh window into how reefs work and influence the surrounding environment— and could even point to new ways to keep an eye on reef health.

Digital twin (DT) technology is emerging as a core solution for future marine development and intelligent ocean management. The review systematically reviews digital twin applications in the marine field, clarifies its concept, proposes a five-layer framework, and summarizes key technologies, including sensing, data management, modeling, simulation, and monitoring. It highlights DT’s ability to synchronize physical marine systems with virtual models in real time, enabling simulation, prediction, optimization, and decision-making. The authors further outline challenges and development prospects, showing how DT can support deep-sea resource exploitation, offshore wind energy, marine engineering, vessel autonomy, environmental monitoring, and system reliability assessment.

Underwater wireless power transfer is emerging as a key technology for enabling long-duration, maintenance-free operation of autonomous underwater vehicles (AUVs). This review provides the most comprehensive overview to date of magnetic-coupling-based underwater wireless charging, addressing challenges such as eddy current losses in seawater, misalignment caused by ocean dynamics, and the growing need for simultaneous transfer of power and data. By comparing transmitter–receiver coil structures, compensation networks, and control strategies, the research identifies design pathways that significantly enhance efficiency, stability, and tolerance to dynamic marine conditions. The work also highlights emerging simultaneous wireless power and data transfer (SWPDT) methods that could reshape the future of marine sensing and robotic operations.

A research team from City University of Hong Kong (CityUHK) recently collaborated with an international research team to publish a study revealing a correlation between global contamination of per- and polyfluoroalkyl substances (PFAS) in globally consumed edible marine fish and associated human health risks.

The study found that consumers may be exposed to elevated levels of PFAS by consuming imported fish such as salmon, tuna, swordfish and cod — even in regions with low environmental pollution — thereby increasing food‑safety risks.

A research team led by Prof. QIAN Peiyuan, Chair Professor of the Department of Ocean Science at The Hong Kong University of Science and Technology (HKUST), in collaboration with the Southern Marine Science and Engineering Guangdong Laboratory (Guangzhou), and the Yellow Sea Fisheries Research Institute of the Chinese Academy of Fishery Sciences (CAFS), has achieved a significant breakthrough in understanding the adaptive strategies of the deep-sea black coral Bathypathes pseudoalternata (B. pseudoalternata) and its symbiotic microbiome. The study has been published in the top international journal Cell Host & Microbe.
