Ice shell thickness reveals water temperature on ocean worlds

Decades before any probe dips a toe—and thermometer—into the waters of distant ocean worlds, Cornell astrobiologists have devised a novel way to determine ocean temperatures based on the thickness of their ice shells, ...

After intense predictions, what happened to El Niño?

After many predictions, on September 19, the Australian Bureau of Meteorology formally announced an El Niño for the summer of 2023/2024, several months after it had been declared by other international meteorological agencies.

Satellites increasingly critical for monitoring ocean health

Playing a huge role in moderating the climate, oceans are fundamental to the functioning of our planet. Understanding more about how seawater temperatures are rising and how oceans are absorbing excess atmospheric carbon ...

New tool skillfully predicts marine habitat shifts

As global temperatures rise, so do ocean temperatures. The ocean absorbs about 90% of the world's excess heat, and this leads to changes to the marine environment that go beyond temperature, making some areas uninhabitable ...
