Understanding Extratropical Ocean-Atmosphere Interactions and their Impact on Northern Hemisphere Jet Stream Variability

The interaction between the oceans and the atmosphere plays a vital role in shaping the Earth’s climate. Changing sea surface temperatures can heat or cool the atmosphere, and changes in the atmosphere can do the same to the ocean surface. This excha

A New Way to Estimate the Age of Microplastics in the Upper Ocean

How old is that microplastic? A new way to es

Researchers from Kyushu University and Asahi Kasei Corporation have developed a new way to estimate the age of microplastics found in the upper oceans. The new method combines plastic oxidation analysis with UV exposure and ambient temperature. By applying their new method to microplastics found across the North Pacific Ocean, the team found that the age of microplastics in nearshore regions ranged from 0 to 5 years old, whereas microplastics from offshore regions ranged from 1 to 3 years old.
