Is sea spray losing its sparkle?
Atmospheric aerosols are tiny particles that scatter and absorb sunlight but also influence climate indirectly through their role in cloud formation. One of the largest sources of aerosols is sea spray which is produced over the world’s oceans. Understanding how these particles take up water from the atmosphere, their so-called hygroscopicity, is important because it determines how much sunlight they …
ACES researcher received award for excellence in aerosol science

The Arctic subsea permafrost is thawing faster than previously thought
The permafrost in the ocean bottom below the East Siberian Arctic Sea is thawing at a rate of 14 cm per year. That’s a lot faster than for permafrost on land and the process may eventually lead to increased global warming through increased release of methane according to a new study published in Nature Communications by ACES researchers and international colleagues. …
