Yet in 2011, Arctic skies experienced the most severe ozone depletion ever measured in the north. The reasons why are now explained in a paper published in the Journal of Geophysical Research-Atmospheres headed by lead author Susan E.

Three discrete explosions occurred at 5:00 am, 9:17 am, and 11:44 am Saturday, while subsequent less powerful rumbles on Sunday denoted an ongoing low-level eruption. The sequence of eruptions emitted ash, gas, and [...]]]> http://frontierscientists.com/2013/05/monitoring-volcanic-mount-cleveland/feed/ 1 http://frontierscientists.com/2013/05/monitoring-volcanic-mount-cleveland/ http://feedproxy.google.com/~r/FrontierScientists/~3/lorEUXqp00U/ http://frontierscientists.com/2013/04/big-booms-over-the-northland/#comments Tue, 30 Apr 2013 18:01:27 +0000 Laura http://frontierscientists.com/?p=4453 by Ned Rozell Near a small village in Russia, Marina Ivanova stepped into cross-country skis and kicked toward a hole in the snow.
