Prima harta 3D a calotei glaciare din Groenlanda, oferind informatii detaliate despre varsta si structura diferitelor straturi de gheata, a fost elaborata cu ajutorul datelor furnizate de Agentia spatiala americana (NASA), conform paginii de internet a acestei institutii americane.

Realizarea a fost posibila prin coroborarea unor informatii anterioare cu cele obtinute cu un radar special in cadrul operatiunii IceBridge a NASA, care a efectuat peste o suta de zboruri in acest scop.

Acest nou si urias volum de date arata cum au evoluat straturile de gheata si care este situatia astazi”, a explicat principalul autor al studiului, Joe MacGregor, specialist in domeniul studierii ghetii la The University of Texas din Austin.

ENGLISH – Peering into the thousands of frozen layers inside Greenland’s ice sheet is like looking back in time. Each layer provides a record of not only snowfall and melting events, but what the Earth’s climate was like at the dawn of civilization, or during the last ice age, or during an ancient period of warmth similar to the one we are experiencing today. Using radar data from NASA’s Operation IceBridge, scientists have built the first-ever comprehensive map of the layers deep inside the ice sheet.
