Mercury-laden fog swirls coastal California scientists
2015/9/9
What do the roof of a building in a West Coast redwood forest, a bluff in California chaparral, and a research vessel in Monterey Bay have in common?
They're often draped in tendrils of fog. That mak...
The toxic metal mercury is present only at trace levels in the ocean, but it accumulates in fish at concentrations high enough to pose a threat to human and environmental health. Human activity has dr...

Researchers at the University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science developed and tested a new sensor to detect ambient levels of mercury in the atmosphere. Funded through ...
Analysis of Mercury Concentrations in Indiana Soil to Evaluate Patterns of Long-Term Atmospheric Mercury Deposition
atmospheric deposition mercury emission soil mercury concentration
2015/1/16
Mercury (Hg) has proven to be a risk to the public, mainly through the consumption of fish. Because of this, many fish consumption advisories have been issued in Indiana. Although much is known about ...

When effective theories predict: the inevitability of Mercury's anomalous perihelion precession
Mercury’s Orbits in Newton’s Theory perturbations
2011/8/31
If the concepts underlying Effective Theory were appreciated from the earliest days of Newtonian gravity, Le Verrier’s announcement in 1845 of the
anomalous perihelion precession of Mercury would hav...
