How do fossil fuels influence the atmospheric chemistry of the Arctic? This is what a recent study published in Nature ...

Researchers in the lab of Erich Osterberg (pictured), an associate professor of earth sciences at Dartmouth, found that levels of methanesulfonic acid (MSA), an airborne byproduct of marine ...

"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 ...
