Pfupisa nyaya yacho:  Nguva nenguva, chando chakakura chinobuda munzvimbo yakaisvonaka yeAntarctica choenda mugungwa. Muna March, NASA yakakwanisa kutora chiitiko ichi chinoshamisa kubva muchadenga mukati menzira yakanga yave ichiitwa kwemwedzi. Gomo guru reaizi, rakakura kupfuura Manhattan, rakaonekwa neU.S. National Ice Center (NIC) richibuda muGetz Ice Shelf kuWest Antarctica. Dzorera pasi kuti uone vhidhiyo. Mwedzi wapera, NASA yakaona iceberg yakareba makiromita 27 ichiberekwa muWest Antarctica's Getz Ice Shelf. Mufananidzo uri kuruboshwe unoratidza nzvimbo yacho iceberg isati yatyora matatu uye kurudyi chikara cheberg chiri kuyangarara mugungwa. Mazaya echando ari muGungwa reAmundsen kumadokero kweAntarctica ari kurasikirwa nechando nokukurumidza zvikuru kupfuura kumwe kwose kuri mukondinendi yacho uye ndiwo anogovera zvikurusa kukwira kwemwero wegungwa. Yakareba makiromita 27, iceberg inonzi B-34 inoita seyakatsemuka ndokupinda muGungwa reAmundsen pakati nepakati kusvika pakupera kwaFebruary 2015, rakadaro sangano reNASA. The Moderate Resolution Imaging Spectroradiometer (Modis) iri pamasatellite eTerra neAqua eNasa yakatora mifananidzo yaibatanidza chiitiko chokubereka. B-34 ndiyo iceberg yechi34 kubva ku'B' quadrant yeAntarctica kuti inocherechedzwa neNIC. The new berg ichiri duku, zvisinei, pane yakwegura zvikuru B-15T - chidimbu cheB-15 icho chakatanga kuputsika kubva kuRoss Ice Shelf muna March 2000. Mufananidzo wokutanga (kuruboshwe) unoratidza iceberg musi waFebruary 16, apo yakanga ichiri yakabatana nechando. Pakazosvika February 28 (pakati), rinoratidzika kuva rakaparadzana zvishoma. Musi waMarch 5 (kurudyi), inenge yava kutenderera zvakasununguka. B-34 ndiyo iceberg yechi34 kubva ku 'B' quadrant yeAntarctica ichange ichiteverwa neNIC. Mazaya echando ari munharaunda iyi ari kurasikirwa nechando nokukurumidza kupfuura chero kupi zvako mukondinendi uye ndiwo anobatsira zvikuru mukukwira kwemwero wegungwa. Mazaya echando makuru anogona kuva nezvakakura zvaanokanganisa muSouthern Ocean. Somuenzaniso, mvura inotonhorera inenge yawedzerwa mugungwa remunyu, inogona kukanganisa mafungu egungwa uye kutenderera kwemvura. Zvisinei, vatsvakurudzi vakaratidza kuti kunyange mvura yakachena yakawanda...
Iceberg yakaputsika kubva kuGetz Ice Shelf ndokuenda kuGungwa reAmundsen imwe nguva pakati - kusvika - pakupera kwaFebruary. Nharaunda iyi iri kurasikirwa nechando nokukurumidza kupfuura dzimwe nzvimbo dzose dziri mukondinendi uye ndiyo inonyanya kukonzera kukwira kwemwero wegungwa. Masayendisiti ari kubatanidza mifananidzo yakaita seiyi neruzha runobva mumakomo echando kuti aone kuti mazaya echando ari kunyunguduka sei.
