POSTECH-KRISO team develops an ultra-light underwater lens for broadband low-frequency sound focusing.

High-resolution sediment analyses from the Arabian Sea reveal, for the first time, that summer and winter monsoons respond differently to global climate change. Researchers from the University of Bremen contributed to the study, published in the journal Nature Geoscience.

Far above the weather we feel at the surface, enormous waves are constantly shaping the atmosphere. These waves, known as Rossby waves, help steer the jet stream and guide the pathways of cold surges, storms, heavy rainfall, and other high-impact weather events. When Rossby waves grow large enough, they can overturn and “break,” much like ocean waves. Scientists from Florida State University examined Rossby wave breaking in two major global models and find Rossby wave breaking errors are not random technical details, but systematic forecast drifts that vary by region and breaking type.

Wave energy has long been seen as a promising source of clean electricity. The ocean is always moving, and that motion carries a huge amount of energy. But many wave energy devices have one important limitation: they do not naturally move in sync with ocean waves. When that happens, they capture less power.

Researchers from ESPOL, Stevens Institute of Technology, and partner institutions tested a simple passive way to tune a wave energy device so it can respond better to changing sea conditions. Their idea uses submerged cones attached to the sides of a floating platform. As the platform moves, the cones trap water and change the system’s motion, helping it adjust more naturally to long ocean swells.

A new study led by the University of Plymouth has used more than six decades of data to show that plankton abundance is declining across vast swathes of the North East Atlantic – a region covering the Atlantic Ocean from Portugal to Norway, and the entirety of the North Sea.

Researchers at KAUST have conducted the first global assessment of how marine ecosystems responded during 2023, the first year when global temperatures temporarily exceeded 1.5°C above pre‑industrial levels. The team documented 201 ecological impact events across the world’s oceans, creating one of the most comprehensive records of marine disruptions during an extreme warming year.
