A new three-dimensional model of the fault beneath the Marmara Sea in Türkiye reveals where a future major earthquake could take place, as reported by researchers from Science Tokyo. Using electromagnetic measurements, the team mapped hidden structures that help explain how earthquakes initiate and where ruptures could occur in this region. The findings help improve earthquake forecasts and could guide disaster prevention strategies for millions living in Istanbul and nearby, where seismic risk is high.

AI analysis of 20 years of satellite data shows floating macroalgae blooms expanding worldwide, with rapid growth beginning around 2008–2010. While floating algae can support marine life offshore, large blooms threaten coastal ecosystems, tourism and local economies when they reach shore.

A research team has evaluated a collection of climate models to better understand how well they can simulate multiyear El Niño events and their impact on spring precipitation over southern China. Their study showed that while many climate models can reproduce the multiyear El Niño events, most of them struggle to simulate their impacts on southern China’s spring precipitation.

A team of shark researchers from the University of Hawaiʻi at Mānoa has solved a long-standing mystery, identifying the first-ever documented mating hub for tiger sharks, Olowalu, Maui. This challenges the conventional understanding of tiger sharks as purely solitary animals, revealing a predictable seasonal convergence of mature males and females that coincides with the humpback whale calving season in Hawaiʻi.

The Oceanography Society (TOS) has selected Dr. Elva Escobar Briones of the Universidad Nacional Autónoma de México; Instituto de Ciencias del Mar y Limnología, as the recipient of the TOS Mentoring Award, recognizing her outstanding and sustained excellence in mentoring the next generation of ocean scientists, as well as her leadership in advancing inclusion, equity, and capacity building in oceanography. Her achievements will be celebrated during the TOS Honors Breakfast on February 24, 2026, during the Ocean Sciences Meeting in Glasgow, Scotland.
