MESSENGER Spacecraft Reveals More Hidden Territory on Mercury
MESSENGER Spacecraft Hidden Territory Mercury
2009/11/24
A NASA spacecraft's third and final flyby of Mercury gives scientists, for the first time, an almost complete view of the planet's surface and provides new scientific findings about this relatively un...
MESSENGER Spacecraft Prepares for Final Pass by Mercury
MESSENGER Spacecraft Final Pass Mercury
2009/9/28
NASA's Mercury Surface, Space Environment, Geochemistry, and Ranging spacecraft known as MESSENGER will fly by Mercury for the third and final time on Sept. 29. The spacecraft will pass less than 142 ...
Oceanic influence on atmospheric mercury at coastal and inland sites: a springtime noreaster in New England
Oceanic influence atmospheric mercury springtime noreaster New England
2009/6/22
Continuous measurements of elemental (Hg0) and reactive mercury were conducted at two sites in New Hampshire during a powerful April 2007 noreaster. During the most intense period of the storm, enhanc...
Comparison of mercury in atmospheric deposition and in Illinois and USA soils
mercury atmospheric deposition soil geology Illinois USA
2009/5/18
It has been reported that most mercury (Hg) in USA soils is from atmospheric Hg deposition, mostly from anthropogenic sources. This paper compares the rates of atmospheric Hg deposition to amounts of ...
Mercury concentrations and pools in four Sierra Nevada forest sites,and relationships to organic carbon and nitrogen
Mercury concentrations pools Sierra Nevada forest sites organic carbon nitrogen
2010/1/20
This study presents data on mercury (Hg) concentrations, stochiometric relations to carbon (C) and nitrogen (N), and Hg pool sizes in four Sierra Nevada forest sites of similar exposure and precipitat...

Role of phytoplankton in mercury cycling in the San Francisco Bay estuary
Role of phytoplankton he San Francisco Bay estuary
2014/4/17
To study the role of phytoplankton in mercury cycling, we measured methylmercury (MeHg) and total
mercury (HgT) in surface waters during the spring 2003 phytoplankton bloom in San Francisco Bay. Cond...
Gaseous mercury distribution in the upper troposphere and lower stratosphere observed onboard the CARIBIC passenger aircraft
Gaseous mercury distribution upper troposphere lower stratosphere
2009/3/31
Total gaseous mercury (TGM) was measured onboard a passenger aircraft during monthly CARIBIC flights (Civil Aircraft for Regular Investigation of the Atmosphere Based on an Instrumented Container) mad...
Gaseous elemental and reactive mercury in Southern New Hampshire
Gaseous elemental reactive mercury Southern New Hampshire
2009/3/31
We conducted measurements of Hg0 and RGM at two inland sites, Thompson Farm (TF) and Pac Monadnock (PM), and a marine site (Appledore Island (AI)) from the UNH AIRMAP observing network in New Hampshir...
In situ measurements of speciated atmospheric mercury and the identification of source regions in the Mexico City Metropolitan Area
speciated atmospheric mercury source regions Mexico City Metropolitan Area
2009/3/12
In order to expand the currently limited understanding of atmospheric mercury source-receptor relationships in the Mexico City Metropolitan Area, real time measurements of atmospheric mercury were mad...
A numerical modelling study on regional mercury budget for eastern North America
numerical modelling regional mercury budget eastern North America
2009/3/10
In this study, we have integrated an up-to-date physio-chemical transformation mechanism of Hg into the framework of US EPA's CMAQ model system. In addition, the model adapted detailed calculations of...
Modelling of Mercury in the Arctic with the Danish Eulerian Hemispheric Model
Mercury Arctic Danish Eulerian Hemispheric Model
2009/3/10
A new 3-D mercury model has been developed within the Danish Arctic Monitoring and Assessment Programme (AMAP). The model is based on the Danish Eulerian Hemispheric Model, which in the original versi...
The fate and transport of mercury over Europe is studied using a regional Eulerian transport model. Because gaseous elemental mercury is a long-lived species in the atmosphere, boundary conditions mus...
Circumpolar transport and air-surface exchange of atmospheric mercury at Ny-Ålesund (79° N), Svalbard, spring 2002
Circumpolar transport atmospheric mercury Svalbard
2008/11/27
Mercury in different environmental compartments has been measured at Ny-Ålesund (78°54' N, 11°53' E) during an intensive campaign, 17 April to 14 May 2002. Time-resolved speciated determination ...
A synthesis of atmospheric mercury depletion event chemistry in the atmosphere and snow
synthesis atmospheric mercury depletion chemistry atmosphere and snow
2008/11/3
It was discovered in 1995 that, during the spring time, unexpectedly low concentrations of gaseous elemental mercury (GEM) occurred in the Arctic air. This was surprising for a pollutant known to have...
