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 ...
A Dartmouth-led study on ice cores from Alaska and Greenland found that air pollution from the burning of fossil fuels reaches the remote Arctic in ...
Multidecadal declines in methanesulfonic acid in arctic ice cores reflect increasing anthropogenic pollution in the industrial era rather than declining marine primary production, according to ...
