Kutsemuka kwakangoerekana kwakura pamusoro pemakiromita gumi nerimwe muna Zvita uye rava makiromita makumi masere pakureba ine 18,5 kilometres chete kutyora zvakakwana. Mvura inodziya pasi pesherefu uye nemhepo inodziya pamusoro inogona kunge yakakonzera kukura kwekuwedzera, kunyangwe vesaenzi parizvino vasina humbowo hwakajeka hwezvakakonzera.

Swansea University purofesa uye mutungamiriri wechikwata chekutarisa chekupenga Adrian Luckman akaudza BBC kuti kana iceberg ikasaparadzaniswa Mumwedzi mishoma inotevera, iwe ungangoshamisika kwazvo kuti hazvina kuitika seizvi:

Izvo hazvina kunge zvakakwana isina-gore mifananidzo kubva kuLandsatAsi isu takakwanisa kubatanidza akati wandei radar mifananidzo yaEsa Sentinel-1 kuti uone huwandu, uye saka zvinoita sekunge zvisingadzivisike kuti kubvaruka kuzere kuchaitika.

El dambudziko chairo nekupwanya iceberg ndeyekuti izvi zvinogona kukanganisa vakasara vaLarsen C. Shelf rakavakidzana rinozivikanwa saLarsen B uye rakakamurwa kuva zviuru zvezvimedu kubva 2002. Kana Larsen C akatambura zvakafanana, mwero wegungwa unogona kukwira nemasendimita masere nemasendimita makumi maviri. , iyo inogona kukanganisa nzvimbo dzekugungwa.

Zvichazova nyaya yemwedzi izvo isu tinogona kuziva kana iro chando shefu chaizvo izvo isu taitoziva nezvekurambana kwake mwedzi mina yapfuura, inoramba isingabatike uye haina kupatsanurwa kubva kuAntarctica.


Izvo zviri muchinyorwa zvinoomerera pamisimboti yedu ye tsika dzekunyora. Kuti utaure chikanganiso tinya pano.
