Lapho izingcezu ezinkulu zeqhwa ziphuma eziqwini zeqhwa bese zingena olwandle, zidala amagagasi aletha amanzi afudumele olwandle engxenyeni yeqhwa, okwenza kube nzima ukuncibilika. Ucwaningo olwenziwe yiYunivesithi yaseZurich naseWashington lusebenzisa ubuchwepheshe be-fiber optic ukukhombisa okokuqala ukuthi le nqubo iqhuba kanjani ukuncibilika kweqhwa. Funda kabanzi »

Uma amazinga okushisa omhlaba enyuka ngama-degree Celsius angu-2,7 – okuhambisana nenqubomgomo yesimo sezulu yamanje – ​​kuyosala ingxenye eyodwa kwezine kuphela yesisindo seqhwa. Lokhu kuwumphumela wocwaningo lwamazwe ngamazwe oluhlanganyelwe yiNyuvesi yaseBremen.

Ososayensi base-University of Bremen bathole ukuthi e-Arctic fjords, ukuncibilika kweqhwa okubangelwa ukushintsha kwesimo sezulu kwandisa amazinga ensimbi esindayo futhi kushintsha i-microbiome ye-algae ensundu eyakha indawo yokuhlala. Njengoba i-algae yakha isisekelo sewebhu yokudla, lokhu kungaba nemiphumela ephawulekayo, ebhubhisayo emvelweni nasemnothweni.

Ucwaningo oluholwa yi-University of Potsdam lubonisa ukuthi izikhukhula ezivela eziqhingini zeqhwa ezincibilikayo ngokuvamile azibeki usongo olukhulayo ezindaweni eziphakeme zezintaba. Nakuba iziqhingi zeqhwa emhlabeni wonke zincibilika, okudala isikhala sokukhula kwamachibi futhi okungenzeka ukuthi angazinzi, amachibi amancane aya ngokuya egcwala ezindaweni eziningi, njengoba abacwaningi base-University of Potsdam bethole. Lokhu kube yisihloko sengxoxo yesayensi iminyaka eminingi... Funda kabanzi »
