Kwenzani ukuguquka kwesimo sezulu ezilwandle zethu?

Ukuguquka kwesimo sezulu kuthinta izilwandle

Njengoba sike sakhuluma kwezinye izikhathi, ukuguquka kwesimo sezulu kuthinta wonke amagumbi omhlaba. Futhi-ke, bekungeke kube kuncane olwandle nasolwandle. Imiphumela yalo ebhubhisayo iguqula izimo zokuphila kuzo zonke izilwandle zomhlaba.

Okwamanje, umphumela owenza ushintsho olukhulu ezimweni zokuphila ezilwandle ukwanda kwamazinga okushisa emanzini angaphezulu. Kwenzani ukuguquka kwesimo sezulu ezilwandle zethu?

Ukwanda kwamazinga okushisa olwandle

izinga lokushisa kwezilwandle liyakhuphuka

Amazinga okushisa kwamanzi angaphezulu ayanda futhi ngawo, i-phytoplankton, okuyisisekelo sakho konke ukudla kochungechunge lokudla olwandle, kuyehla. Izimo zezulu kanye nezinguquko ekushiseni kubangela ushintsho kumagagasi olwandle.

Izinguquko emisakazweni yolwandle zingazithinta kanjani izinhlobo zezinto eziphilayo? Ilula kakhulu, i-phytoplankton yakhiwa izitshalo ezincane eziqhakaza futhi ezitholakala emanzini. Njengoba imisinga namaphethini wokujikeleza kwawo kuguquka, ukudla kwezinhlobo eziningi ezikusekelayo kushintsha indawo. Ngale ndlela, baphoqa lezi zinhlobo ukuba zigudluze futhi ziguqule indawo ezihlala kuyo, zibeke engcupheni yokubhekana nezinye izinhlobo zezilwane eziyingozi kakhulu futhi ziziphoqe ukuba zivumelane nezimo ezintsha.

Konke lokhu kubanga imithelela emibi emikhiqizweni yasolwandle futhi kunciphisa amathuba okusinda kwezinhlobo eziningi.

Ucwaningo ngokuguquka kwesimo sezulu ezilwandle

i-photosynthesis ezilwandle nasolwandle iyancipha ngenxa yokushintsha kwesimo sezulu

Ucwaningo luthole izindawo eziyisithupha ezinkulu zeplanethi okufanele zize zivikelwe ukuze impilo iqhubeke nokuba khona olwandle. Ucwaningo lwenziwa ngabaphenyi base-Australia, New Zealand nabaseSpain. Ukuze kuphenywe izici zemvelo nokuthi ukuguquka kwesimo sezulu kubathinta kanjani, basebenzise imininingwane evela kumilaza yama-satellite aqoqwe eminyakeni engama-30 edlule ukuthola ukuthi ukuguquka kwesimo sezulu kuzithinta kanjani izilwandle zomhlaba wonke.

Ngenxa yokuthuthuka kwezobuchwepheshe, kube nokwenzeka ukuthola izithombe zokuthi ukuguquka kwesimo sezulu kuzithinta kanjani izilwandle emhlabeni jikelele ngokulungiswa kwezithombe akufinyelelwanga kuze kube manje. Yize i-physics eyisisekelo ithi izimo ezisendaweni enamanzi zigcina zifana yonke indawo, ngobukhulu bolwandle izinto azinjalo. Ngalesi sizathu, ukufudumala kwembulunga yonke akufani kuwo wonke amanzi futhi akuyona nje umbuzo wobubanzi.

Imiphumela yokushintsha kwesimo sezulu ezilwandle

ukuncibilika kubangela ushintsho kumisinga yolwandle

Imiphumela edalwa ukuguquka kwesimo sezulu ezilwandle, noma okungenani okuphawuleka kakhulu futhi esheshayo, yile:

  • Ukufudumala kwamanzi angaphezulu
  • Ukwehla kokukhiqizwa kwe-chlorophyll ezitshalweni
  • Izinguquko emaphethini wemisinga yolwandle

Ucwaningo lushicilelwe ku Ukuthuthukiswa Kwezesayensi, futhi ikhombisa izitayela ezimbili eziphikisanayo. Ngakolunye uhlangothi, ukufudumala kwamanzi angaphezulu akuyekile ukwanda kusukela ngawo-80 wekhulu leminyaka elidlule. Ngakolunye uhlangothi, ukuhlushwa kwe-chlorophyll nge-cubic meter ngayinye akuyekanga ukuncipha kusukela lapho. Umsebenzi uphinde walinganisa okuguquguqukayo kwesithathu: imisinga yolwandle, labo ababhekele ukusabalalisa ukushisa emhlabeni wonke, ngokuhlangana nokunyakaza komkhathi, kanye nalabo besimo sezulu. Yize kune-heterogeneity enkulu, ngokujwayelekile le mifula yasolwandle iyancipha.

Ukuhlanganisa zonke lezi zinto ukuthi ososayensi bakwazile kanjani ukucacisa endaweni ngayinye futhi bakwazi ukukala imithelela yokuguquka kwesimo sezulu esilinganisweni sesifunda nesasendaweni. Izifunda ezibandayo yilawo ahlupheka ngokwanda okuthe xaxa emazingeni okushisa amanzi awo futhi kulapho, lapho amanzi ahlanzekile ancibilika eqala ukusebenza, aphazamisa imisinga yasolwandle. Ngokuya ngezinhlobonhlobo zezinto eziphilayo, iNyakatho ye-Atlantic kanye nomngcele osenyakatho nePacific babhekene nokufudumala okunomthelela ekuthombekeni kwezinto eziphilayo zasolwandle.

Njengoba ukwazi ukubona, ukuguquka kwesimo sezulu kuthinta wonke amagumbi eplanethi futhi lapho ifundelwa ngokwengeziwe, kulapho kuqwashiswa khona ukuthi imiphumela ingeyangempela futhi ayiyeki ukwanda.
