1. m\u00e4rtsil 2007 asusid Alain Hubert ja Dixie Dansercoer teele m\u00e4rkimisv\u00e4\u00e4rsele ekspeditsioonile, mille eesm\u00e4rk oli k\u00f5ndida Siberist Gr\u00f6\u00f6nimaale. Kolm kuud hiljem, p\u00e4rast paljusid ohte ja peaaegu katastroofe, on nende 2000 km pikkune r\u00e4nnak \u00fcle j\u00e4ise looduse l\u00f5pule j\u00f5udmas t\u00e4nu Envisatile, ESA orbiidil asuvale silmale taevas.<\/p>\n<\/div>\n

Esialgu l\u00e4ks k\u00f5ik h\u00e4sti, hoolimata \u00e4\u00e4rmiselt karmidest, ohtlikest ja f\u00fc\u00fcsiliselt rasketest tingimustest. Siis hakkas merej\u00e4\u00e4 ootamatult murduma, kui kaks Belgia maadeavastajat l\u00e4henesid Gr\u00f6\u00f6nimaa rannikule. Neil ei j\u00e4\u00e4nud muud \u00fcle, kui proovida leida teed laia avamereala \u00fcmber.<\/p>\n

\u00d5nneks said nad toetuda kahele Envisati pardal olevale seadmele \u2013 igasuguste ilmastikutingimustega t\u00f6\u00f6tavale radarisensorile ja optilisele MERIS-seadmele. Uurides hoolikalt muutuvate j\u00e4\u00e4olude satelliidipilte, suutis Leif Toudal Pedersen (Taani Riiklik Kosmosekeskus) aidata uurijatel v\u00e4ltida kiiresti lagunevat j\u00e4\u00e4v\u00e4lja.<\/p>\n

Meeskond on n\u00fc\u00fcd stabiilsel j\u00e4\u00e4l. J\u00e4\u00e4nud on v\u00e4hem kui 50 km ja nad n\u00e4evad eespool selgelt Gr\u00f6\u00f6nimaad. Julged maadeavastajad j\u00f5uavad eeldatavasti sel n\u00e4dalal oma pika r\u00e4nnaku l\u00f5ppu, mis h\u00f5lmab kogu Arktika basseinit.<\/p>\n

Nende kurnav teekond \u00fcle j\u00e4\u00e4ga kaetud P\u00f5hja-J\u00e4\u00e4mere, mida tuntakse nimetusega \u201eArctic Arc Expedition\u201d, on \u00fcks paljudest teaduslikest tegevustest, mis toimuvad Rahvusvahelise Polaaraasta raames. Kaks kogenud polaaruurijat olid eriti huvitatud lumekatte paksuse andmete kogumisest. Seda teavet kasutatakse ESA CryoSat-2 missiooni ettevalmistamiseks, mis peaks orbiidile j\u00f5udma 2009. aastal.<\/p>","protected":false},"excerpt":{"rendered":"
