Read MoreDMS: The Climate Gas You’ve Never Heard Of
For generations of mariners, a tangy, almost sweet odor served as a signal that land was nearby. What sailors called “the smell of the shore” had the opposite meaning to…

“Give me half a tanker of iron, and I’ll give you an ice age” may rank as the catchiest line ever uttered by a biogeochemist. The man responsible was…
Read MoreExtinction of Neanderthals Was Not a Climate Disaster Scenario
For the past few decades, scientists have offered several competing theories for what led to the extinction of the Neanderthals, with much of the debate focusing on the relative roles of climate change versus conflict with modern humans. Now one theory can be ruled out. New research by a multidisciplinary, international team?including paleoclimatologist Konrad Hughen of the Woods Hole Oceanographic Institution?shows that Neanderthals did not die out at a time of extreme and sudden climatic change, as some researchers have suggested.
Read MoreAcid Rain Has a Disproportionate Impact on Coastal Waters
The release of sulfur and nitrogen into the atmosphere by power plants and agricultural activities plays a minor role in making the ocean slightly more acidic on a global scale, but the impact is greatly amplified in the shallower waters of the coastal ocean, according to new research by atmospheric and marine chemists.

Researchers from the Woods Hole Oceanographic Institution (WHOI) have found a new and substantial pathway for mercury pollution flowing into coastal waters. Marine chemists have detected much more dissolved mercury entering the ocean through groundwater than from atmospheric and river sources.
