Herfra forsker vitenskapsfolk p\u00e5 globale problemer som klimaendringer og stigende havniv\u00e5. To ESA-satellitter, Sentinel-1 og Sentinel-2, observerte omr\u00e5det rundt Halley VI-basen fra bane rundt jorden. De oppdaget at det hadde oppst\u00e5tt en stor sprekk i isen! Siden den ble oppdaget i oktober, fikk den kallenavnet \u2019Halloween-sprekken\u00bb. Dette ville sette forskernes liv i fare, s\u00e5 det ble besluttet \u00e5 evakuere dem og stenge Halley VI for vinteren.<\/p>\n<\/div>\n<p>Det er ganske vanlig at det oppst\u00e5r sm\u00e5 sprekker i ishyllene, og noen ganger faller biter ut over kanten og ned i havet, hvor de blir til isfjell. Men \u00abHalloween Crack\u00bb, som ble oppdaget av Sentinel-satellittene, var stor og ble stadig st\u00f8rre \u2013 med opptil 600 meter hver dag! Halley VI-laboratoriet er egentlig utformet slik at det kan flyttes vekk fra sprekker i isen, men \u00abHalloween-sprekken\u00bb beveget seg i sikksakk p\u00e5 en m\u00e5te som var vanskelig \u00e5 forutsi, noe som gjorde det sv\u00e6rt risikabelt for forskerne \u00e5 bli v\u00e6rende. For \u00e5 beskytte dem mot fare ble de flyttet ut av laboratoriet og i sikkerhet.<\/p>\n<figure class=\"wp-block-image size-large\" data-width=\"1920\" data-credit=\"ESA\" data-detail-url=\"https:\/\/www.esa.int\/ESA_Multimedia\/Images\/2017\/02\/Halley_VI\" 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\/2017\/02\/halley_vi\/18248141-2-eng-GB\/Halley_VI.jpg\" alt=\"The entire Halley VI station has now been evacuated\"><figcaption>Hele Halley VI-stasjonen er n\u00e5 evakuert<\/figcaption><\/figure>\n<p>Vanligvis bor og arbeider rundt 70 personer p\u00e5 Halley VI i sommerm\u00e5nedene.
