1. marca 2007 sta se Alain Hubert in Dixie Dansercoer odpravila na izjemno odpravo, na kateri sta pe\u0161 prehodila pot od Sibirije do Grenlandije. Tri mesece kasneje, po \u0161tevilnih nevarnostih in skoraj\u0161njih nesre\u010dah, se njuna 2.000 km dolga pot \u010dez ledeno divjino bli\u017ea koncu, zahvaljujo\u010d Envisatu, sateliti ESA, ki kot oko opazuje nebo.<\/p>\n<\/div>\n

Sprva je kljub izredno te\u017ekim, nevarnim in fizi\u010dno zahtevnim razmeram vse potekalo gladko. Nato pa se je morski led nepri\u010dakovano za\u010del lomiti, ko sta se belgijska raziskovalca pribli\u017eevala grenlandski obali. Nista imela druge izbire, kot da posku\u0161ata najti pot okoli obse\u017enih odsekov odprtega morja.<\/p>\n

Na sre\u010do so se lahko zanesli na podporo dveh instrumentov na satelitu Envisat \u2013 radarskega senzorja za vse vremenske razmere in opti\u010dnega instrumenta MERIS. S skrbnim pregledovanjem satelitskih posnetkov spreminjajo\u010dih se lednih razmer je Leif Toudal Pedersen (Danski nacionalni vesoljski center) raziskovalcem pomagal izogniti se hitro razpadajo\u010di ledeni ploskvi.<\/p>\n

Ekipa je zdaj na trdnem ledu. Do cilja jih lo\u010di manj kot 50 km, pred seboj pa imajo jasen pogled na Grenlandijo. Pri\u010dakuje se, da bodo neustra\u0161ni raziskovalci ta teden dosegli konec svojega dolgega pohoda \u010dez celoten arkti\u010dni bazen.<\/p>\n

Njihova naporna pot \u010dez z ledom pokrit Arkti\u010dni ocean, znana kot ekspedicija \u00bbArctic Arc\u00ab, je ena od \u0161tevilnih znanstvenih dejavnosti, ki potekajo v okviru Mednarodnega polarnega leta. Oba izku\u0161ena polarna raziskovalca sta bila \u0161e posebej zainteresirana za zbiranje podatkov o globini snega. Te informacije bodo uporabljene za pripravo na misijo CryoSat-2 Evropske vesoljske agencije (ESA), ki naj bi v orbito poletela leta 2009.<\/p>","protected":false},"excerpt":{"rendered":"
