„Nejd\u0159\u00edv jsme nev\u011bd\u011bli, co to je.“<\/strong><\/p>\n

V\u011bdci z NASA shrom\u00e1\u017edili n\u011bkolik \u00fa\u017easn\u00fdch m\u011b\u0159en\u00ed b\u011bhem letu nad arktick\u00fdm ledem v Gr\u00f3nsku v dubnu 2024.<\/p>\n

Radarov\u00e9 za\u0159\u00edzen\u00ed na palub\u011b letadla NASA Gulfstream III\u00a0objevilo opu\u0161t\u011bn\u00e9 \u201em\u011bsto pod ledem<\/a>\u00a0\u201c: poz\u016fstatek studen\u00e9 v\u00e1lky, kter\u00fd kdysi pou\u017e\u00edval jako vojensk\u00e1 z\u00e1kladna US Army Corps of Engineers.<\/p>\n

Extr\u00e9mn\u011b vzd\u00e1len\u00e1 z\u00e1kladna zvan\u00e1 Camp Century zahrnuje rozs\u00e1hlou s\u00ed\u0165 tunel\u016f vyhlouben\u00fdch do povrchov\u00fdch vrstev ledu asi 150 mil (241 km) ve vnitrozem\u00ed. V letech 1959 a\u017e 1967 se zde testovala mo\u017enost odpalov\u00e1n\u00ed jadern\u00fdch raket z Arktidy.<\/p>\n

<\/p>\n

Radarov\u00e1 data z\u00edskan\u00e1 b\u011bhem posledn\u00edho letu ukazuj\u00ed \u0159adu struktur zasahuj\u00edc\u00edch do ledov\u00e9ho povrchu pod 30 metr\u016f silnou vrstvou ledu a sn\u011bhu, kter\u00e1 se nahromadila za posledn\u00edch 56 let.<\/p>\n

„Hledali jsme ledov\u00e9 dno a tam se objevuje Camp Century,“ uvedl v prohl\u00e1\u0161en\u00ed kryosf\u00e9rick\u00fd v\u011bdec Alex Gardner z NASA’s Jet Propulsion\u00a0Laboratory<\/a>\u00a0. „Nejd\u0159\u00edv jsme nev\u011bd\u011bli, co to je.“<\/p>\n

Data shrom\u00e1\u017edil UAVSAR (Uninhabited Aerial Vehicle Synthetic Aperture Radar), namontovan\u00fd na b\u0159i\u0161e Gulfstream III.<\/p>\n

„V nov\u00fdch datech jsou jednotliv\u00e9 struktury Tajn\u00e9ho m\u011bsta viditeln\u00e9 zp\u016fsobem, kter\u00fd nikdy p\u0159edt\u00edm nebyl vid\u011bn,“ uvedl v prohl\u00e1\u0161en\u00ed v\u011bdec NASA Chad Greene, kter\u00fd byl b\u011bhem pr\u016fzkumu na palub\u011b letadla.<\/p>\n

V\u011bdci pou\u017e\u00edvaj\u00ed tyto mapy k odhadu, kdy by mohl b\u00fdt t\u00e1bor znovu odhalen, kdy\u017e ledov\u00fd \u0161t\u00edt taje, co\u017e je proces urychlen\u00fd zm\u011bnou klimatu.<\/p>\n

Odborn\u00edci ji\u017e nazna\u010dili, \u017ee \u00falo\u017ei\u0161t\u011b by mohlo b\u00fdt odkryto\u00a0do konce stolet\u00ed<\/a>\u00a0, co\u017e by mohlo m\u00edt nezam\u00fd\u0161len\u00e9 n\u00e1sledky v\u010detn\u011b vystaven\u00ed radioaktivn\u00edmu odpadu a chemik\u00e1li\u00edm vyplavuj\u00edc\u00edm se do okol\u00ed.<\/p>\n

<\/p>\n

Objev Camp Century byl pro t\u00fdm naprosto ne\u010dekan\u00fdm v\u00fdsledkem. Hlavn\u00edm c\u00edlem mise bylo studovat dopady klimatick\u00fdch zm\u011bn na Arktidu.<\/p>\n
