Converting the vibrations generated by water currents in contact with an object into energy. This is the basis of the new system designed by Francisco Huera, a researcher in the Department of Mechanical Engineering at the Universitat Rovira i Virgili (URV). The device harnesses the energy of water currents from the vibrations that occur when water passes around a cylinder and creates vortices behind it. This method has a very simple structure: a submerged cylindrical tube hanging from an axis that oscillates like a pendulum when the water current makes it vibrate. The results of this research have been published in the Journal of Fluids and Structures.

The Oceanography Society has selected Dr. Zhongping Lee of Xiamen University as the recipient of the 2026 Nils Gunnar Jerlov Medal, recognizing his transformative contributions to understanding how light interacts with the ocean, as well as his sustained leadership in education, interdisciplinary research, and collaborative work with meaningful societal impact. Dr. Lee will be recognized at The Oceanography Society Honors Breakfast, February 24, 2026, during the Ocean Sciences Meeting in Glasgow, Scotland, as well as during the Ocean Optics XXVII Conference in Ghent, Belgium, in September 2026.

Over the past two decades ENSO, a climate pattern in the equatorial Pacific Ocean that includes El Niño and La Niña, has been the dominant driver of  total water storage extremes at the global level. What’s more, the researchers found that ENSO has a synchronizing effect on water storage extremes across continents.

Newly published interdisciplinary research led by the University of Tennessee, Knoxville, and University of Maryland shows viral infection of blue-green algae in the ocean stimulates productivity in the ecosystem and contributes to a rich band of oxygen in the water.

A new scientific study has revealed major gaps in the protection of critical shark and ray habitats across the Western Indian Ocean – but has also highlighted Seychelles as a clear regional leader in safeguarding these species.

445 million years ago, life on our planet was forever changed. During a geological blink of an eye, glaciers formed over the supercontinent Gondwana, drying out many of the vast, shallow seas like a sponge and giving us an ‘icehouse climate’ that, together with radically changed ocean chemistry, ultimately caused the extinction of about 85% of all marine species – the majority of life on Earth.

In a new Science Advances study, researchers from the Okinawa Institute of Science and Technology (OIST) have now proved that from this biological havoc, known as the Late Ordovician Mass Extinction (LOME), came an unprecedented richness of vertebrate life. During the upheaval, one group came to dominate all others, putting life on the path to what we know it as today: jawed vertebrates.

A new international analysis published in Advances in Atmospheric Sciences on 9 January finds that the Earth’s ocean stored more heat in 2025 than in any year since modern measurements began.

Existing sea surface height prediction models require excessive computing power and training times and suffer from progressive error accumulation, limiting their accuracy to 14–15 days in the future. A team of researchers recently developed a lightweight deep learning model called GTU-Net with unique loss function and physical constraints that improve the reliability of medium- and long-range sea surface height predictions to improve long-term ocean monitoring, climate studies and operational ocean forecasting.
