1. mars 2007 la Alain Hubert og Dixie Dansercoer ut p\u00e5 en bemerkelsesverdig ekspedisjon for \u00e5 g\u00e5 fra Sibir til Gr\u00f8nland. Tre m\u00e5neder senere, etter mange farer og nesten-katastrofer, n\u00e6rmer deres 2 000 km lange fottur gjennom den iskalde villmarken seg slutten, takket v\u00e6re Envisat, ESAs \u00f8ye i himmelen.<\/p>\n<\/div>\n

Til \u00e5 begynne med gikk alt bra, til tross for de ekstremt t\u00f8ffe, farlige og fysisk krevende forholdene. S\u00e5 begynte havisen uventet \u00e5 bryte opp da de to belgiske oppdagelsesreisende n\u00e6rmet seg Gr\u00f8nlands kyst. De to hadde ikke annet valg enn \u00e5 pr\u00f8ve \u00e5 finne en vei rundt de store omr\u00e5dene med \u00e5pent vann.<\/p>\n

Heldigvis kunne de stole p\u00e5 st\u00f8tte fra to instrumenter om bord p\u00e5 Envisat \u2013 allv\u00e6rsradarsensoren og det optiske MERIS-instrumentet. Ved \u00e5 n\u00f8ye studere satellittbilder av de skiftende isforholdene kunne Leif Toudal Pedersen (Det danske nasjonale romsenter) hjelpe oppdagelsesreisende med \u00e5 unng\u00e5 isdekket som raskt var i ferd med \u00e5 bryte opp.<\/p>\n

Teamet befinner seg n\u00e5 p\u00e5 stabil is. Med mindre enn 50 km igjen har de god utsikt over Gr\u00f8nland foran seg. De uredde oppdagelsesreisende forventes \u00e5 n\u00e5 m\u00e5let for sin lange ferd gjennom hele det arktiske bassenget denne uken.<\/p>\n

Deres slitsomme reise over det isdekte Arktiske hav, kjent som \u00abArctic Arc Expedition\u00bb, er en av mange vitenskapelige aktiviteter som gjennomf\u00f8res i l\u00f8pet av Det internasjonale polar\u00e5ret. De to erfarne polarfarerne var spesielt interessert i \u00e5 samle inn data om sn\u00f8dybde. Denne informasjonen skal brukes til \u00e5 forberede ESAs CryoSat-2-oppdrag, som skal settes i bane i 2009.<\/p>","protected":false},"excerpt":{"rendered":"
