In 2016, an outbreak of anthrax killing thousands of reindeer and affecting dozens of humans occurred on the Yamal peninsula, Northwest Siberia, after 70 years of epidemiological situation without outbreaks. The trigger of the outbreak has been ascribed to the activation of spores due to permafrost thaw that was accelerated during the summer heat w...

Abstract As a solution for the increasing energy demand in Jordan, nuclear power was recommended for the energy mix at the national level. However, investigations of the meteorological conditions and mass transfer have never been conducted and reported earlier based on typical Jordanian conditions in order to have prior knowledge in case of a futur...

Mercury analyzers experiment. In 2015 at Amderma the mercury analyzer Lumex RA-915AM was installed in parallel with Tekran 2527A to measure background concentrations of mercury. The Lumex analyzer is a candidate considering good correlation (R2 = 0.95) between parallel measurements of both analyzers of low mercury concentrations at mid-latitudes (S...

We estimate the long-range atmospheric transport of elemental mercury in the Northern Hemisphere and present new data for volcanic eruptions in Iceland. At the Polar station Amderma (Russia) of long-term observations of elemental mercury concentration (2009–2010), a change in the dynamics was recorded. For seasonal variability at the period from 20...

The northern Eurasian regions and Arctic Ocean will very likely undergo substantial changes during the next decades. The Arctic–boreal natural environments play a crucial role in the global climate via albedo change, carbon sources and sinks as well as atmospheric aerosol production from biogenic volatile organic compounds. Furthermore, it is expec...
