Long-running partnership with Saildrone aims to improve hurricane forecasting and rapid intensification models Saildrone announced plans to deploy 10 Saildrone Explorer unmanned surface vehicles (USVs) during the 2026 hurricane season in partnership with National Oceanic and Atmospheric Administration (NOAA). The mission will support hurricane forecasting and storm research across the Atlantic ba…

Ministry of Earth Sciences highlighted the growing role of artificial intelligence in strengthening ocean governance, maritime monitoring, and environmental resilience during the India AI Impact Summit 2026. The discussions reflected increasing global interest in using advanced technologies to improve management Read More ... The post AI strengthens ocean governance and maritime resilience first …

This paper presents a conceptual framework for the reinterpretation of planetary gravityin which the observed gravitational field of celestial bodies is not considered solely a directconsequence of total mass, but rather the result of an interaction between the primarygravity of the planetary core and the gravitational attenuation produced by surroundingconfined mass layers.In this model, the pla…

What does a surge in ocean temperatures, compounded with El Niño, bode for the summer? An enormous marine heatwave off the US west coast is ringing alarm bells among ocean and atmospheric scientists as new data shows its ecological and environmental effects are intensifying. The unusual area of warm water has persisted since peaking in size during September 2025 and still stretches thousands of m…

Natural impulsive events such as earthquakes, volcanic eruptions, and thunderstorms, as well as anthropogenic events such as rocket launches and atmospheric re-entries, can generate acoustic-gravity waves (AGWs) that propagate in the upper-atmosphere and produce traveling ionospheric disturbances (TIDs) observable with GNSS total electron content (TEC) measurements. We developed an algorithm for …

The world’s oceans are rising at an accelerating pace, and scientists now say they can fully explain what’s driving it. Warming seawater is the biggest factor, while melting glaciers and polar ice sheets are increasingly pouring more water into the oceans each year. Researchers also solved a puzzling mismatch in sea level measurements that had lingered for years.

Though numerical models and popular films like An Inconvenient Truth projected Arctic ice collapse due to global warming and then climate change, the reverse was true in the real world. Ice expanded. That changed in 2015 and a new model estimates why. The authors say the Southern Ocean which surrounds Antarctica has gotten warmer, bringing salty water from the deep up to the surface. Those water …

A routine seafloor scan near Sicily caught something that wasn't supposed to exist. What surfaced in the data rewrites maps and forces experts to rethink the risks.

The French Riviera may look like an unlikely place for a tsunami disaster, but scientists warn the threat is far more real than most people realize. Historical events and new modeling show that destructive waves have already struck the Mediterranean coast — and could hit again with very little warning. Some tsunami scenarios could reach beaches in under 10 minutes, leaving almost no time for trad…

Forecasters already rely on satellites, buoys and hurricane hunter aircraft to monitor ocean conditions. Sharks, however, may offer a way to fill gaps in places where traditional tools are sparse or expensive.

Nature Communications, Published online: 19 May 2026; doi:10.1038/s41467-026-73130-z Winter marine heatwaves in the Indian Ocean can intensify spring and summer marine heatwaves in the Caribbean Sea through an atmospheric bridge. An eastward propagating wave train alters the regional Hadley circulation, reducing latent heat loss from the ocean and driving sea surface warming.
