Isipheqululisakho asisekeli le fomethi yevidiyo.

I-Navy of Mexico isuse umkhomo we-humpback, owagezwa ngasosebeni kwedolobha laseManzanilla, esifundazweni saseMexico eColima, kusho umbiko we-Associated Press.

Isilwane esingamamitha ayishumi ubude satholakala ngabadobi bendawo ebhishi lasePunta de Cabos. Ngokushesha babika abakutholile emaphoyiseni. Izazi zebhayoloji kanye namavolontiya avela kubahlali bendawo afike endaweni yesehlakalo.

Isikebhe sokugada ogwini, izimoto ezimbili kanye nomvubukuli, kanye nabangaphezulu kwekhulu bamatilosi esikhungweni esiseduze seNavy yaseMexico, babandakanyeka emsebenzini wokuhlenga. Kuthathe ama Marines cishe usuku ukubuyisa umkhomo onamathani ayisithupha entweni yawo yendabuko.

Ngokusho kochwepheshe, phakathi kwezizathu ezidala ukuthi imikhomo igezwe ogwini, kungahle kwehle ukutholakala kokudla, ukusakazeka kwamagciwane athathelanayo, umthelela ongaba khona wokushisa komhlaba, kanye nokwanda kwesilinganiso sokuzala kanye nokwanda kwesibalo sabantu kulezi zilwane.

Yini engaba isizathu sokuziphatha kwalezi zilwanyana ezincelisayo zasolwandle?

Kunezinguqulo ezimbalwa noma ezicatshangelwe ezingaphansi kuleli banga.

Leli cala eMexico akuyona into eyodwa, kuba khona ukuqhuma okukhulu komkhomo e-Australia, New Zealand, eBrazil ...

Umbono othandwa kakhulu uthi umsola ngomsindo wezitimela ezingaphansi komhlaba. Imikhomo iyawuzwa kakhulu umsindo, nomsindo wangaphansi kwezindiza uyizithulu kubo. Umkhomo oselahlekelwe ukuzwa, kanye naye ulahlekelwa amandla akhe okuhamba endaweni ezungezile, okuba yisizathu sokuthi bangagcini ngokuziphonsa ogwini, kodwa futhi bakwenze kaninginingi. Kepha lokhu akuchazi ukuthi kungani imikhomo yaphonswa ogwini ezikhathini zasendulo.

Ngemuva kokuhlola izidumbu zezilwane ezifile, ososayensi baphakamise nokuthi ukugula okubangelwa yi-decompression kwakucindezela kulokhu. Lesi sifo singumphumela wokuncipha okukhulu kwengcindezi yangaphandle. Ngaphezu kwemikhomo, lesi sifo sithinta abahlukahlukene nabamele labo bunjiniyela abasebenza kumakhamera angaphansi kwamanzi.

Kunezindlela eziningi zokuthi kungani imikhomo iphonswa emhlabeni: kusuka ekuguleni nasekungcolisweni kwemvelo.

Ngenxa yemisindo ebukhali, imikhomo iyasaba futhi ikhuphuka ngokushesha kakhulu ezingxenyeni ezingaphezulu zolwandle. Ngenxa yalokhu, ukucindezela kwangaphandle kwehla kakhulu, okuba imbangela yokugula kokuwohloka. Ngaphezu kwemigwaqo engaphansi komhlaba, imikhomo ingasatshiswa ngamarokhethi, ama-sonars, ama-radars kanye nemisindo yama-echo. Ngakolunye uhlangothi, lo mbono uqinisekiswa yiqiniso lokuthi izikhathi eziningi imikhomo yayigezwa ngasosebeni ngesikhathi sokuzivocavoca kwezasolwandle lapho kwakusetshenziswa ama-sonar, kodwa ngakolunye uhlangothi, amaGrikhi asendulo ayengenayo into enjalo, kepha imikhomo ibisalahlwa.

Enye inguqulo ukuthi imbangela yokuzibulala ukungasebenzi kahle kwekhampasi enozibuthe, okuthi, ngokwesifiso sabososayensi bezinto eziphilayo, “ifakwe” ebuchosheni balezi zilwane. Nguye obavumela ukuba bazihambele kahle ebumnyameni bezilwandle zomhlaba. Kepha uma kuvela isithiyo se-geomagnetic phambi komkhomo, leli khampasi lingakwazi “ukugqekeza” ngenxa yokuthi umkhomo uphulukana nezinto zalo futhi uphonswe olwandle. Ngokwengxenye lokhu kuchaza ukuthi kungani imikhomo iphonswa emuva.

Ososayensi emhlabeni wonke babhekene nale nkinga, kepha kuze kube manje abayitholi indlela yokuvikela imikhomo ekufeni.

Uhlobo lwesithathu lwabekwa phambili ososayensi baseJapan. Ngokusho kwakhe, ukuzibulala okunjalo kungumphumela wokugcwala futhi kudlala indima yemithetho yemvelo yobukhulu benani labantu. Kepha lo mbono unezinkinga ezinkulu. Eyokuqala yazo ukuthi inani lalezi zilwane okwamanje lincane kakhulu futhi akukho nzima ukuthi lincishiswe. Ukwesibili kwesibili ukuthi kwakunguJapan owayephambili ekudobeni kwemikhomo futhi, njengoba abanye bezazi zemvelo besho, le nguqulo yenziwe ngokwezifiso futhi ihlose ukuqala kabusha ukudoba kwemikhomo.

Uhlobo lwesine lunengqondo ngokwengeziwe, kodwa futhi ngaphandle kwezingqinamba. Iqiniso ngukuthi imikhomo inesilinganiso esingajwayelekile sokuthola usizo kosizo.

Kunoma ikuphi, bahlala bezama ukusiza izihlobo zabo ukuphuma enkingeni.

Futhi uma elinye ilunga lephakethe lithathwe ngengozi emanzini angajulile, khona-ke amanye amalungu ephulo, esezwile izinkomba zezinkathazo, afuna ukusiza umlingani wakho, kodwa ngenxa yalokho bona uqobo baso baluwela ogwini. Ngeshwa, le nguqulo ayichazi ukuthi kungani imikhomo ingenile emanzini futhi ingatholi zimpawu ezivela ezihlotsheni ezifile ezisele ogwini, noma kunjalo, ziphonswa ogwini futhi. Ngaphezu kwalokho, lolu ogwini lungaba ngamashumi noma ngisho namakhulu amakhilomitha ukusuka endaweni yokufa kwamanye amalungu omhlambi wawo.

Mhlawumbe uhlobo olucatshangelwe kakhulu umcabango wokuthi lesi sifo sisolwa. Ama-parasites asezinze emzimbeni wesilwane kukholakala ukuthi angalimaza ubuchopho bawo nezinye izitho ezidlala indima ebalulekile. Lokhu kungaholela ekuphazanyisweni kwengqondo komholi, bese ezinye izilwane zimane ziphonswe ngaphandle kwakhe. Kuliqiniso, futhi, akucaci bha ukuthi kungani baphinda baphonswa ngakolunye uhlangothi lapho umholi esevele efile.

Ngaphezu kwalokho, ezilwaneni eziningi, umholi ubekwa esikhundleni cishe ngaso leso sikhathi futhi akuholeli ekweqiseni okunjalo.

Isitatimende sokuthi isizathu ukungcola koLwandlekazi Lomhlaba sithandwa kakhulu. Yebo, ngakolunye uhlangothi, i-polyethylene nemikhiqizo kawoyela kwakuvame ukutholakala ezithweni zokuphefumula zemikhomo eyayihunyushiwe, kodwa ngakolunye uhlangothi, imikhomo ethile inezitho ezihlanzekile ngokuphelele. Ngaphezu kwalokho, esikhathini esiningi ezindaweni lapho kwakhululwa khona amanzi ayehlanzekile. Okufanayo kusebenza emisebeni ye-radiation, okuthi, njengomthetho, nayo engatholakali kulezi zindawo.

Ekugcineni, kucatshangwa ukuthi isizathu silele ekushintsheni kwesimo sezulu. Iqiniso ngukuthi imisinga yase-Antarctic iletha amanzi abandayo nawo. Imikhomo, izama ukufudumala, iqala ukubhukuda emanzini angajulile, lapho ifela khona. Mhlawumbe lolu kuphela uhlobo oluchaza amaqiniso okukhishwa kwemikhomo ogwini ezikhathini ezandulele kwenkathi yezinhlekelele zemvelo.

Noma kungaba njalo, kepha kuze kube manje akukho mpendulo yesayensi etholakele kulo mbuzo, futhi kusethemba kuphela ukuthi impendulo izotholakala ngokuzayo.

Ngeshwa, imikhomo isephakathi kwezilwane ezibhekene nokuqothuka. Ukuqothulwa okungalawulwa kwalezi zilwane kwaqala ngekhulu lamashumi amabili, okuholele, ngokwesibonelo, ekunyamalalisweni okucishe kube ngokuphelele kwemikhaza eluhlaza okwesibhakabhaka, okwathi isigamu sekhulu edlule kwabalelwa ezinkulungwaneni ezinhlanu. Ngenxa yezindlela zokuzivikela, inani labo selicishe laphindeka kabili, kepha futhi lokhu akunakwa, ikakhulukazi ngenxa yokuthi ama-whales azala kancane.
