Infrastructure on top of Danielssenkrateret. Jan Mayen, North Atlantic Island
Staffed by four people year round, the weather station at Jan Mayen is considered vitally important by the Norwegian Meteorological Institute. Monthly mean temperatures run 21 degrees to 40.8 degrees Fahrenheit, a surprisingly tight range due to the effects of the Gulf Stream meeting the East Greenland Current. These effects are what the researchers stationed there are hoping to better understand. The climate and environment of Jan Mayen has been deemed so delicate that the Norwegian government declared it a protected nature reserve in 2010.
