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.

The Oceanography Society (TOS) has awarded the Ocean Observing Team Award to the Global Ocean Ship-Based Hydrographic Investigations Program (GO-SHIP), recognizing the program’s groundbreaking and sustained contributions to ocean observing that have transformed scientific understanding of the global ocean and delivered profound societal benefits. Team members will be recognized during The Oceanography Society’s Awards Breakfast taking place on Tuesday, February 24, 2026, during the Ocean Sciences Meeting in Glasgow, Scotland.
