Tres meses despu\u00e9s, tras sortear muchos peligros y bordear el desastre, su recorrido a lo largo de 2.000 km de desierto helado est\u00e1 llegando a su fin, gracias al sat\u00e9lite Envisat, el ojo de la ESA que observa desde el cielo.<\/p>\n<\/div>\n<p>Al principio todo march\u00f3 bien, a pesar de las condiciones sumamente duras y peligrosas, adem\u00e1s de f\u00edsicamente exigentes. Pero despu\u00e9s el hielo empez\u00f3 a resquebrajarse de manera imprevista mientras los dos exploradores belgas se acercaban a la l\u00ednea costera de Groenlandia. No tuvieron m\u00e1s opci\u00f3n que buscar la manera de bordear las amplias extensiones de agua.<\/p>\n<figure class=\"wp-block-image size-natural\" data-width=\"400\" data-credit=\"Leif Toudal Pedersen, Danish National Space Centre, Danish Technical University\" data-detail-url=\"https:\/\/www.esa.int\/ESA_Multimedia\/Images\/2007\/06\/Sea_ice_in_Nares_Strait_between_Greenland_and_Canada2\" 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\/06\/sea_ice_in_nares_strait_between_greenland_and_canada2\/17868931-2-eng-GB\/Sea_ice_in_Nares_Strait_between_Greenland_and_Canada.jpg\" alt=\"Sea ice in Nares Strait between Greenland and Canada\"><figcaption>Hielo marino en el estrecho de Nares, entre Groenlandia y Canad\u00e1<\/figcaption><\/figure>\n<p>Afortunadamente, pudieron contar con la ayuda de dos instrumentos del Envisat: el sensor de radar para todo tipo de condiciones meteorol\u00f3gicas y el instrumento \u00f3ptico MERIS. Tras examinar minuciosamente las im\u00e1genes de sat\u00e9lite de las condiciones cambiantes del hielo, Leif Toudal Pedersen (Centro Espacial Nacional de Dinamarca) pudo ayudar a los exploradores a evitar la capa de hielo que se desintegraba r\u00e1pidamente.<\/p>\n<p>El equipo ya se encuentra sobre hielo estable. A menos de 50 km del final de su caminata, ya pueden divisar claramente a Groenlandia en la distancia. Se espera que los intr\u00e9pidos exploradores finalicen esta semana su larga marcha a trav\u00e9s de toda la cuenca \u00e1rtica.<\/p>\n<p>Su penoso viaje a trav\u00e9s del Oc\u00e9ano \u00c1rtico recubierto de hielo, conocido como Expedici\u00f3n del Arco \u00c1rtico, es una de las muchas actividades cient\u00edficas que se est\u00e1n llevando a cabo durante el A\u00f1o Polar Internacional. Los dos experimentados exploradores polares estaban especialmente interesados en recopilar datos obtenidos en la profundidad de los hielos. Dicha informaci\u00f3n se utilizar\u00e1 en los preparativos de la misi\u00f3n CryoSat-2 de la ESA, cuya entrada en \u00f3rbita est\u00e1 prevista para 2009.<\/p>","protected":false},"excerpt":{"rendered":"<p>On 1 March 2007, Alain Hubert and Dixie Dansercoer set off on a remarkable expedition to walk from Siberia to Greenland.
