Viele Entdecker kamen bei der Suche nach einer Nordwestpassage, die den Atlantik und den Pazifik verbindet, ums Leben. Doch die arktische Eisdecke schmilzt mittlerweile rapide. Neue Radarbilder der ESA-Sonde \u201eEnvisat\u201c zeigen, dass die Ausdehnung des arktischen Meereises nun so gering ist wie nie zuvor seit Beginn der Satellitenmessungen vor fast 30 Jahren. Die Folge ist die vor\u00fcbergehende \u00d6ffnung der zuvor unpassierbaren Nordwestpassage.<\/p>\n<\/div>\n<p>Die arktische Eisdecke nimmt im n\u00f6rdlichen Winter zu und nimmt im n\u00f6rdlichen Sommer ab. Allerdings beschleunigt sich der sommerliche Schmelzprozess. Ein Mosaik aus fast 200 Bildern, die Envisat im September 2007 aufgenommen hatte, zeigte, dass die Nordwestpassage vollst\u00e4ndig befahrbar war, w\u00e4hrend die Nordostpassage entlang der sibirischen K\u00fcste nur teilweise blockiert war.<\/p>\n<figure class=\"wp-block-image size-large\" data-width=\"1186\" data-credit=\"ESA\" data-detail-url=\"https:\/\/www.esa.int\/ESA_Multimedia\/Images\/2007\/09\/A_2007_ice-free_portion_of_the_Northwest_Passage2\" data-licence=\"ESA Standard Licence\" data-licence-url=\"https:\/\/www.esa.int\/ESA_Multimedia\/Terms_and_conditions_of_use_of_images_and_videos_available_on_the_esa_website\"><img decoding=\"async\" loading=\"lazy\" style=\"max-width:100%;height:auto\" src=\"https:\/\/www.esa.int\/var\/esa\/storage\/images\/esa_multimedia\/images\/2007\/09\/a_2007_ice-free_portion_of_the_northwest_passage2\/17885582-2-eng-GB\/A_2007_ice-free_portion_of_the_Northwest_Passage.jpg\" alt=\"A 2007 ice-free portion of the Northwest Passage\"><figcaption>Ein eisfreier Abschnitt der Nordwestpassage aus dem Jahr 2007<\/figcaption><\/figure>\n<p>Der d\u00e4nische Wissenschaftler Leif Toudal Pedersen sagte: \u201cWir haben beobachtet, dass die Eisfl\u00e4che auf knapp 3 Millionen Quadratkilometer geschrumpft ist, was etwa 1 Million Quadratkilometer weniger ist als in den Jahren 2005 und 2006.
