A Dartmouth study has solved a marine mystery by linking an ocean biomarker to pollution levels. A study led by Dartmouth ...

Monthly methane sulfonic acid flux from 1960–1971 (light gray bars), 1972–2001 (dark gray bars), and 2002–2014 (black bars), respectively (Yutaka Kurosaki, Sumito Matoba, et al ...

Air pollution from fossil fuel burning reaches the remote Arctic in amounts large enough to alter its atmospheric chemistry, according to a study from Dartmouth College. The findings highlight the far ...

The researchers detected this footprint in an unexpected place—they measured declines in an airborne byproduct of marine phytoplankton activity known as methanesulfonic acid, or MSA, captured in ...

"The more phytoplankton, the more of these fatty acid compounds and methanesulfonic acid we're then going to see in the ice core. So, if we're seeing more ice core compounds from these sources ...

They discovered an unexpected decline in methanesulfonic acid (MSA), a byproduct of marine phytoplankton activity, coinciding ...
