Zdanowicz. (1896-1977), Chinese Journal of Geophysics (2000-2018), International Gaseous elemental mercury (GEM), reactive gaseous mercury (RGM) and mercury associated with particles (Hg−P) were measured during this study. Geophysics, Mathematical Xiaohang Xu, Na Liu, Matthew S. Landis, Xinbin Feng, Guangle Qiu. J. Sommar, M. E. Andersson, H.-W. Jacobi. [9] Observations by the MESSENGER probe in 2009 showed that calcium is concentrated mainly near the equator—opposite to what is observed for sodium and potassium. [8] In 1998 another element, calcium (Ca), was detected with column density three orders of magnitude below that of sodium. METALLIC SPECIES IN MERCURY’S EXOSPHERE: EMMI/NEW TECHNOLOGY TELESCOPE OBSERVATIONS. Mercury has a very tenuous and highly variable atmosphere (surface-bound exosphere) containing hydrogen, helium, oxygen, sodium, calcium, potassium and water vapor, with a combined pressure level of about 10 −14 bar (1 nPa). and Paleomagnetism, History of Learn about our remote access options. Gaseous elemental mercury in the marine boundary layer and air-sea flux in the Southern Ocean in austral summer. Rapid Reduction and Reemission of Mercury Deposited into Snowpacks during Atmospheric Mercury Depletion Events at Churchill, Manitoba, Canada. A year after the sodium discovery, Potter and Morgan reported that potassium (K) is also present in the exosphere of Mercury, though with a column density two orders of magnitude lower than that of sodium. Sodium ion exosphere of Mercury during MESSENGER flybys. The exospheric species originate either from the Solar wind or from the planetary crust. Singh. Juan Yu, Zhouqing Xie, Hui Kang, Zheng Li, Chen Sun, Lingen Bian, Pengfei Zhang. Interaction of the surfaces of the Moon and Mercury with their exospheric atmospheres. Singh, N.K. The Surface of Mercury as Seen by Mariner 10. Arctic source for elevated atmospheric mercury (Hg 0 ) in the western Bering Sea in the summer of 2013. Transport of mercury in the Arctic atmosphere: Evidence for a spring-time net sink and summer-time source. Article Views are the COUNTER-compliant sum of full text article downloads since November 2008 (both PDF and HTML) across all institutions and individuals. Increasing chloride concentration causes retention of mercury in melted Arctic snow due to changes in photoreduction kinetics. Plasma Sources of Solar System Magnetospheres. A. Steffen, J. Bottenheim, A. Cole, T. A. Douglas, R. Ebinghaus, U. Friess, S. Netcheva, S. Nghiem, H. Sihler, R. Staebler. Publications of the Astronomical Society of the Pacific. Its orbit around the Sun takes 87.97 days, the shortest of all the planets in the Solar System. Revolutionizing Our Understanding of the Solar System via Sample Return from Mercury. Biological and Chemical Redox Transformations of Mercury in Fresh and Salt Waters of the High Arctic during Spring and Summer. Convective forcing of mercury and ozone in the Arctic boundary layer induced by leads in sea ice. Viktor V. Kalinchuk, Evgeny A. Lopatnikov, Anatoliy S. Astakhov, Maxim V. Ivanov, Limin Hu. The concentrations of atmospheric gaseous elemental mercury (GEM), gaseous oxidized mercury (GOM), and particle-bound mercury (particles with diameter smaller than 2.5 μm; PBM2.5) were continuously observed for a period of over 10 years at Cape Hedo, located on the north edge of Okinawa Island on the border of the East China Sea and the Pacific Ocean. This expedition covered large areas of the North Atlantic and Arctic Oceans between latitudes 54°N and 85°N and longitudes 16°W and16°E. Objects, Solid Surface E.A. Mercury's thin atmosphere is constantly being "blown away" into space by the pressure of sunlight and by the solar wind.

The near-surface abundance of this newly detected constituent is roughly comparable to that of sodium. Distribution of atmospheric gaseous elemental mercury (Hg(0)) from the Sea of Japan to the Arctic, and Hg(0) evasion fluxes in the Eastern Arctic Seas: Results from a joint Russian-Chinese cruise in fall 2018.
