1992 y\u0131l\u0131nda bir ara\u015ft\u0131rmac\u0131 ekibi, Tibet Platosu\u2019nda bulunan bir buzuldan \u00f6rnek toplam\u0131\u015f ve bu buzul tabakas\u0131n\u0131n 15.000 ya\u015f\u0131nda oldu\u011funu ke\u015ffetmi\u015fti.

Daha sonraki s\u00fcre\u00e7te ayn\u0131 ekip ayn\u0131 buzul tabakas\u0131ndan yine \u00f6rnek ald\u0131. 2015 y\u0131l\u0131nda al\u0131nan bu \u00f6rnekler de sakland\u0131. Biliminsanlar\u0131 bu iki \u00f6rnek \u00fczerinde \u00e7al\u0131\u015fma yaparak, buzul tabakas\u0131n\u0131n i\u00e7erdi\u011fi organizmalar\u0131 analiz etti.<\/p>\n

Ara\u015ft\u0131rmac\u0131lar bu buzul tabakas\u0131ndaki t\u00fcrler \u00fczerinde inceleme yapacaklar\u0131 i\u00e7in, \u00e7al\u0131\u015fma ortam\u0131n\u0131n steril olmas\u0131na fazlaca \u00f6zen g\u00f6sterdi. \u00c7\u00fcnk\u00fc ortam di\u011fer mikroorganizmalardan ve vir\u00fcslerden ar\u0131nmam\u0131\u015f olursa \u00e7al\u0131\u015fmalar\u0131 etkilenebilir ve hali haz\u0131rda ortamda bulunan di\u011fer t\u00fcrler buz tabakas\u0131 \u00fczerinde bulunan t\u00fcrler ile kar\u0131\u015fabilirdi. Daha da k\u00f6t\u00fcs\u00fc ortamda bulunan mikroorganizmalar analizler s\u0131ras\u0131nda kontaminasyona (\u00fczerinde \u00e7al\u0131\u015f\u0131lan materyalin kirlenmesi, yap\u0131s\u0131n\u0131n bozulmas\u0131) neden olabilirdi. Bu nedenle olduk\u00e7a \u00f6zenli davran\u0131ld\u0131.<\/p>\n

\u00d6rneklerin \u00e7al\u0131\u015fma s\u0131ras\u0131nda da bozulmamas\u0131na dikkat eden ekip so\u011fuk bir ortamda \u00e7al\u0131\u015ft\u0131. Mikroorganizmalar ve vir\u00fcslerle ile \u00e7al\u0131\u015fma prosed\u00fcrlerini yerine getiren ara\u015ft\u0131rmac\u0131lar, 28\u2019i modern t\u00fcr olan 33 grup vir\u00fcs cinsini tespit etti. \u0130ki farkl\u0131 \u00f6rnek \u00fczerinde \u00e7al\u0131\u015f\u0131lm\u0131\u015f ve farkl\u0131l\u0131k i\u00e7eren vir\u00fcsler tan\u0131mlanm\u0131\u015ft\u0131. Bunun muhtemel nedeninin zaman i\u00e7inde geli\u015fen iklim de\u011fi\u015fikleri oldu\u011fu tahmin ediliyor. K\u00fcresel \u0131s\u0131nmayla birlikte buzullarda g\u00f6zlenen erimenin eski vir\u00fcs t\u00fcrlerini y\u00fczeye \u00e7\u0131karaca\u011f\u0131 ve b\u00f6ylelikle eski d\u00f6nemlerden kalma vir\u00fcsler \u00fczerinde \u00e7al\u0131\u015fmalar\u0131n s\u00fcrece\u011fi d\u00fc\u015f\u00fcn\u00fcl\u00fcyor.
