\"Savan\u021bii<\/a><\/p>\n

\u00cen Antarctica s-a descoperit un z\u0103c\u0103m\u00e2nt gigantic de granit FOTO: British Antarctic Survey<\/p>\n

O echip\u0103 de savan\u021bi de la British Antarctic Survey (BAS) a reu\u0219it s\u0103 fac\u0103 o descoperire nea\u0219teptat\u0103: un secret pe care Antarctica \u00eel ascunde de mult\u0103 vreme. Continentul alb arat\u0103 ca o calot\u0103 glaciar\u0103 alb\u0103 \u0219i curat\u0103 de la distan\u021b\u0103, dar ac\u021biunea important\u0103 are loc ad\u00e2nc sub suprafa\u021b\u0103. Oamenii de \u0219tiin\u021b\u0103 au g\u0103sit o structur\u0103 neobi\u0219nuit\u0103, un z\u0103c\u0103m\u00e2nt gigantic de granit, cu o grosime de 7 kilometri, ascuns sub ghe\u021barul din Pine Island.<\/p>\n

Rocile roz descoperite \u00een Antarctica dezv\u0103luie<\/a> o structur\u0103 masiv\u0103 ascuns\u0103 sub ghea\u021b\u0103 timp de 175 de milioane de ani. Ceea ce a \u00eenceput ca un mister care implic\u0103 c\u00e2\u021biva bolovani roz ciuda\u021bi s-a transformat \u00eentr-o revela\u021bie<\/a> geologic\u0103 major\u0103, potrivit Earth.<\/p>\n

Descoperirea nu numai c\u0103 r\u0103spunde la \u00eentreb\u0103ri vechi, dar schimb\u0103 \u0219i modul \u00een care vedem trecutul \u0219i viitorul continentului \u00eenghe\u021bat. \u00cen Mun\u021bii Hudson, bolovani de granit roz stau \u00eempr\u0103\u0219tia\u021bi printre roci vulcanice \u00eentunecate. Culoarea lor iese \u00een eviden\u021b\u0103 ca un indiciu l\u0103sat \u00een urm\u0103. Timp de decenii, nimeni nu a \u0219tiut cum au ajuns ace\u0219ti bolovani acolo.<\/p>\n

O echip\u0103 de la British Antarctic Survey (BAS) a decis s\u0103 afle. M\u0103sur\u00e2nd dezintegrarea radioactiv\u0103 din interiorul unor cristale minerale minuscule, oamenii de \u0219tiin\u021b\u0103 au descoperit c\u0103 granitele s-au format acum aproximativ 175 de milioane de ani, \u00een perioada Jurasicului.<\/p>\n

Acest lucru explica v\u00e2rsta lor, dar nu \u0219i loca\u021bia lor. Bolovanii nu \u00ee\u0219i aveau locul pe acei mun\u021bi. R\u0103spunsul a venit de sus. Avioane echipate cu senzori de gravita\u021bie au zburat peste ghe\u021barul Pine Island \u0219i au detectat un semnal ciudat sub ghea\u021b\u0103.<\/p>\n

Datele au dezv\u0103luit un z\u0103c\u0103m\u00e2nt ascuns de granit, lat de aproape 100 de kilometri \u0219i gros de \u0219apte kilometri \u2013 aproximativ jum\u0103tate din m\u0103rimea \u021a\u0103rii Galilor. Acesta z\u0103cea \u00eengropat ad\u00e2nc sub ghe\u021bar, nev\u0103zut timp de milioane de ani.<\/p>\n

\u201eEste remarcabil faptul c\u0103 bolovani de granit roz observa\u021bi la suprafa\u021b\u0103 ne-au condus la un gigant ascuns sub ghea\u021b\u0103\u201d, a declarat Dr. Tom Jordan, autor principal \u0219i geofizician la BAS.<\/p>\n

Rocile sunt o comoar\u0103 de informa\u021bii<\/p>\n

\u201eCombin\u00e2nd datarea geologic\u0103 cu studiile gravita\u021bionale, nu numai c\u0103 am rezolvat un mister despre provenien\u021ba acestor roci, dar am descoperit \u0219i informa\u021bii noi despre cum a curs calota glaciar\u0103 \u00een trecut \u0219i cum s-ar putea schimba \u00een viitor.\u201d<\/p>\n

Aceste cuvinte surprind entuziasmul descoperirii. Bolovanii nu erau aleatori. Erau fragmente din acest gigant subteran, transportate \u00een mun\u021bi de ghea\u021ba antic\u0103.Puterea ascuns\u0103 a ghe\u021barului e dezv\u0103luit\u0103 acum. Cu mii de ani \u00een urm\u0103, \u00een timpul ultimei ere glaciare, ghe\u021barul Pine Island era mai gros \u0219i mult mai puternic dec\u00e2t este ast\u0103zi.<\/p>\n

A smuls roci din patul de granit de dedesubt, le-a mutat prin peisaj \u0219i le-a aruncat pe Mun\u021bii Hudson pe m\u0103sur\u0103 ce ghea\u021ba se sub\u021bia. Fiecare bolovan marcheaz\u0103 acum locul unde se afla odinioar\u0103 ghe\u021barul. Aceste indicii \u00eei ajut\u0103 pe oamenii de \u0219tiin\u021b\u0103 s\u0103 reconstruiasc\u0103 istoria ghe\u021barului. Ei introduc aceste date \u00een modele computerizate care prezic cum s-ar putea mi\u0219ca ghea\u021ba \u00een viitor.<\/p>\n

Modelele precise conteaz\u0103 deoarece ghe\u021barul Pine Island este una dintre regiunile cu cel mai rapid ritm de topire din Antarctica. Ceea ce se \u00eent\u00e2mpl\u0103 acolo afecteaz\u0103 nivelul m\u0103rii la nivel mondial. \u00cen\u021belegerea acestei funda\u021bii ascunse \u00eei ajut\u0103 pe oamenii de \u0219tiin\u021b\u0103 s\u0103 explice de ce Ghe\u021barul Pine Island pierde ghea\u021b\u0103 at\u00e2t de rapid.<\/p>\n

Aceast\u0103 descoperire \u00eembun\u0103t\u0103\u021be\u0219te, de asemenea, modelele care simuleaz\u0103 cre\u0219terea viitoare a nivelului m\u0103rii. Fiecare nou\u0103 informa\u021bie face ca predic\u021biile s\u0103 fie mai fiabile \u0219i ofer\u0103 comunit\u0103\u021bilor de coast\u0103 o imagine mai clar\u0103 despre ceea ce urmeaz\u0103.<\/p>\n

\u201eRocile ofer\u0103 o \u00eenregistrare uimitoare a modului \u00een care planeta noastr\u0103 s-a schimbat \u00een timp, \u00een special a modului \u00een care ghea\u021ba a erodat \u0219i a modificat peisajul Antarcticii\u201d, a spus ea. \u201eBolovanii ca ace\u0219tia sunt o comoar\u0103 de informa\u021bii despre ceea ce se afl\u0103 ad\u00e2nc sub calota glaciar\u0103, departe de a fi accesa\u021bi\u201d, a spus dr. Joanne Johnson, geolog la BAS.<\/p>\n
