Sesihambe ibanga elide “Olwandle Oluthule”

Le bhulogi yavela ekuqaleni I-Ocean Noise ibhulogi evela ku-Ocean Conservation Research

Kuyamangaza ukuthi bangaki abantu emkhakheni wesayensi yolwandle nokongiwa kwesikweletu u-Jacques Cousteau njengogqozi lothando lwabo lolwandle. Lapho nje i-TV yombala yayithuthela egumbini lokuhlala laseMelika Cousteau yayinikeza i-trove emangalisayo futhi ekhangayo yemvelo i-psychedelia ukujabulisa imicabango yethu. Ngaphandle kwe-Cousteau's Self-Contained Underwater Breathing Apparatus (SCUBA) kanye nezithombe zomhleli Luis UMarden kungaba nzima ukucabanga ukuthi intuthuko yesayensi yolwandle (noma isimo solwandle) ingaba kuphi njengamanje. Ukuthi abantu abaningi badonseka ekuthandeni ulwandle ngeminikelo kaCousteau kuwubufakazi bokuthi omunye umboni wemibono angaba nawo kule planethi.

Ngeshwa waphuthelwa yiphuzu elilodwa elincane: Ngokusungula umsebenzi wakhe odume kakhulu ngaphansi kwerubrikhi ethi “Umhlaba Othule” ingxenye ebalulekile yokuhlola imvelo yolwandle iqale sekwephuzile ngempela. Kuvele ukuthi ngenkathi kukhona i-pallet yombala omkhulu phakathi kwe-biota ehlala endaweni i-epipelagic noma indawo yokukhanya kwelanga olwandle (200m nangaphezulu), okungaguquguquki kulo lonke ikholomu yamanzi ukuthi umbono ozwakalayo “uyabusa” ngempela. Uma kubhekwa ukuthi izidalwa zasolwandle eziningi kangaka zihlala emanzini anezinxushunxushu kanye nobumnyama obuyinxenye noma obuphelele lapho ukubonakala kukhawulelwe khona, kungenzeka ukuthi uhla lokujwayela kokuzwakala olwandle alukahlolwa.

Ihlazo lalokhu ukuthi ngenkathi sisanda kuthola imibono mayelana nokuzwela kwezilwane zasolwandle, ukusebenzelana kwezimboni, ezentengiselwano, kanye nezempi nolwandle sekuthuthukile ngaphansi kombono oyiphutha wokuthi ulwandle “Umhlaba Othule,” nalapho isimiso sokuqapha. ishanelwe eceleni ukuze kulunge.

Yebo ukuthandwa kwe-“Izingoma Zomkhomo Womkhomo” kanye nokuhlola kwasekuqaleni kwe-dolphin bio-sonar kwenza abantu abaningi basheshisa “izihlobo” zethu ezincelisayo zasolwandle, kodwa ngaphandle kwezinhlanzi ezisuselwe elebhu. I-audiometry umsebenzi owenziwe Art Popper noRichard Fay, ukuzwa okuncane kakhulu - futhi mhlawumbe okubaluleke nakakhulu, kumbalwa kakhulu kwezinto eziphilayo i-soundscape izifundo zenziwe kucatshangelwa izinhlanzi. Manje sekuya ngokuya kuba sobala ukuthi ngisho nezilwane zasolwandle ezingenamgogodla zincike ekuboneni umsindo - futhi zithintwa umsindo odalwa umuntu.

Ucwaningo lwamuva olushicilelwe ku Imibiko Yesayensi Yemvelo kuveza ukuthi umsindo wokuthutha ukhubaza ukukhula kwe-embryonic kanye nezinga lokusinda konogwaja basolwandle cishe ngo-20%. Phakathi kwezinye izindima, lezi zilwane zigcina i-coral icacile ku-algae - umsebenzi obalulekile onikeza zonke ezinye izingcindezi zemvelo ukuthi amakhorali ahlupheka njengamanje.

Umsindo ngokwawo ungaba inkomba yezindawo ezinempilo zama-coral reef - njengoba nje izindawo ezinempilo ziminyene nomsindo wezinto eziphilayo. Iphepha elishicilelwe kamuva nje ku Inqubekelaphambili Yemvelo Yasolwandle iphakamisa ukuthi umsindo webhayoloji uyinkomba yempilo yezixhobo ezisetshenziswayo kanye nokwehlukahlukana futhi isebenza njengenkomba yokuqondisa yezilwane ezingafuna ukuhlala endaweni. Umsindo omuhle, ominyene, nohlukahlukene webhayoloji udala umsindo webhayoloji ohlukahlukene. Kodwa uma lo msindo webhayoloji uvalwe “umusi” ozwakalayo lapho-ke uzofihlwa kubasebenzi abasha.

Yebo imiphumela yalokhu mayelana nomsindo wesikhathi eside wezimboni ongapheli ufinyelela kude kakhulu. Ngenkathi iningi lomsindo wezimboni nezempi ukunciphisa zigxile ekuvimbeleni ukufa okuyinhlekelele kwezilwane ezincelisayo zasolwandle, uma izinhlanzi ezingavikelekile nezilwane ezingenamgogodla kanye nezindawo ezihlala kuzo zinqotshwa ukuwohloka kwesikhathi eside okuvela emsindweni ophazamisayo osezingeni eliphansi imiphumela ingase ibe mibi kakhulu: “Izwe Elithulile” ngokwesayensi yezinto eziphilayo elinokuduma kuphela kwezimboni. umsindo ukuzwa.
