Ulwandle lweCoral

izilwanyana zaselwandle zekorale

Namhlanje siza kuthetha ngolwandle oluqulathe iziqithi ezininzi ngaphakathi kwaye lwalubekwe ngaphezulu kwayo yonke inkqubo enkulu yamatye e-coral emhlabeni. Imalunga nayo ulwandle lwekorale. Lulwandle oluyinxalenye yoLwandlekazi loMzantsi Pasifiki kwaye lunendawo emalunga ne-4.800.000 yeekhilomitha ezizikwere. Zibaluleke kakhulu ngokwembono yolondolozo lwendalo njengoko kukho iGreat Barrier Reef, eyabhengezwa njengeNdawo yeLifa leMveli lehlabathi yiUNESCO ngo-1981.

Kule nqaku siza kukuxelela ngazo zonke iimpawu, izinto eziphilayo kunye nokubaluleka koLwandle lweCoral.

Iimpawu eziphambili

ulwandle lwekorale

Luhlobo lolwandle oluhlamba amanxweme ala mazwe alandelayo: i-Australia, iNew Caledonia (iFrance), iPapua New Guinea, iSolomon Islands neVanuatu. Igama lalo livela ekuqulatheni iziqithi ezininzi kunye nayo yonke inkqubo yamanzi amakhulu eekorale emhlabeni. Idityaniswe kumntla-ntshona kunye noLwandle iArafura, ngeTorres Strait. Umda umda luLwandle lweSolomon ngasentla, uLwandle lweTasman emazantsi kunye noLwandle oluvulekileyo lwePasifiki empuma.

Lulwandle olunobunzulu obuphakathi kweemitha ezingama-2.394, nangona kwinqanaba lalo nzulu lufikelela kwiimitha ezili-9.140. Olu lwandle lunomdla kwaye kukuba imisinga yayo ephambili yenza i-gyroscope kwicala elichasene newotshi. Kungenxa yokuba eyona ndawo inzulu ivelisa imisinga ehlengahlengiswa sisenzo sefuthe leCoriolis. Inkqubo yangoku ibandakanya iMpuma yeAustralia yangoku. Eli langoku linoxanduva lokuhambisa amanzi ashushu ukusuka emantla ukuya eLwandle lwaseTasman, oluqhele ukubanda. Lo mahluko kumaqondo obushushu yeyona nto ibangela ukuba ubenamandla amakhulu. Okwangoku okuhambisa amanzi abandayo afudumeleyo kuyonyusa amandla ayo ngenyanga kaFebruwari kwaye kubuthathaka kwinyanga ka-Agasti.

Imozulu yoLwandle lweCoral

Umqobo wekorale

Ulwandle lweCoral luneqondo lobushushu eliphakathi ngonyaka elihluka ngokobubanzi esiku bona. Umzekelo, kwicandelo elisemazantsi sinamanzi abandayo ajikeleze i-19 degrees. Kwelinye icala sinenxalenye esemantla, amanzi afudumeleyo anexabiso elijikeleze iidigri ezingama-24. Inesalathiso setyuwa esiya kuba malunga no-34.5-35,5 ‰ (iinxalenye ngewaka), ke ayinamanzi kakhulu. Kwaye amanzi oLwandle lweCoral abonakala kuba enezinga eliphezulu lobukhali, ngakumbi kwiindawo apho kufumaneka khona iingqaqa zekorale.

KwiMeteorology yolu lwandle sifumana iinkanyamba ezomeleleyo ezixhaphakileyo kulo. Ezi nkanyamba ziqhelekile kwaye zibeka emngciphekweni kubemi abahlala kunxweme lwayo nasekuhambeni kwabo. Izitshingitshane zaseTropiki zenzeka rhoqo ngexesha lehlobo.

Iziqithi zeCoral Sea

irifu yekheroli

Njengoko besesitshilo ngaphambili, lulwandle oluneziqithi ezininzi ngaphakathi kwalo. Ngaphandle kweGreat Barrier Reef sifumana amaqela eziqithi abalulekileyo. Iingqaqa zayo kunye neziqithi zizityebi ngokukodwa kwindalo. Phakathi kwazo sifumana iintaka kunye nobomi obuninzi bamanzi. Obu butyebi bendalo iyantlukwano abuthandeli kuphela imisebenzi yokuloba, kodwa zikwayindawo yabakhenkethi eyaziwayo. Ineziqithi ezininzi ezinokhenketho kwilizwe lonke nakwamanye amazwe. Ndiyabulela koku, uqoqosho lwamazwe ajikeleze uLwandle lweCoral lunokuphumelela kakuhle. Masibone ukuba zeziphi iziqithi eziphambili zoLwandle lweCoral:

Zimi kufutshane nonxweme olusempuma-mpuma we-Australia kwaye zenziwe malunga neziqithi ezingama-30 kunye neziqithi ezimalunga nama-50 ezincinane. Ezi ziqithi zahlulwe zangamacandelo ahlukeneyo kwaye zezi zilandelayo:

  • Iqela laseMantla ntshona, ekuyo eyona mimandla ibalulekileyo I-Osprey Reef, iLihou Reef kunye Isiqithi saseWillis.
  • UMellish Reef, ulwalwa lwamanzi olubekwe ngaphezulu kweekhilomitha ezingama-300 kunxweme lwase-Australia.
  • IQela lase Mzantsi mpuma, ezenziwe ngamatye UFrederick, uKenn, uSaumarez, iWreck kunye neCato, apho eyona ndawo iphakamileyo yezi ziqithi ikhona, ziimitha ezi-6 ngaphezulu komphakamo wolwandle.
  • Iqela lase Mzantsi, zenziwe yimifula UMiddleton noElizabeth.

Iziqithi zeChesterfield ziseFrance kwaye zibekwe malunga neekhilomitha ezingama-550 kumantla ntshona eNew Caledonia. Kukho iziqithi ezili-11 ezingenabemi ngokupheleleyo ezandisiweyo zimalunga neekhilomitha ezili-11 zesikwere. Zonke iziqithana kunye nemilambo yekorale zisasazeke ngaphakathi koxande oluziikhilomitha ezingama-120 × 70. Iziqithi ezikulo xande zinikwe la magama alandelayo:

  • Isla Igama loqhagamshelwano Renard.
  • Ukuhlawuliswa iqhoshana.
  • yawa Amathambo.
  • Ziqithi Chesterfield embindini.
  • Iziqithana I-Avon
  • Longle Longue.
  • Iziqithana Ugcino.
  • Iziqithana Ukumisa.
  • Isiqithi Isidlo.
  • Iingqaqa eBellona.

Ukubaluleka kwemithombo yeekorale

Siyazi ukuba iingqaqa zekorale zifana namahlathi emvula eza ngeendlela ezahlukeneyo, ubukhulu, kunye nemibala. Kwaye kukuba ziikholoni zamawaka ezilwanyana ezincinci ezibalulekileyo ekusindeni kwamakhulu ezigidi zabanye abantu kwaye zibala i-25% yezilwanyana zaselwandle zehlabathi. Kule mijelo uya kufumana iintlanzi ezincinci kunye ne-mollusks kunye ne-turtles, iintaka zamanzi kunye neentlanzi. Ezi ecosystems zibuthathaka kwaye ukusinda kwazo kusemngciphekweni ngenxa yeziphumo zobushushu behlabathi.

Iingqaqa zekorale aziboneleli kuphela indawo yokuhlala kunye nokutya kwipesenti yezilwanyana zaselwandle, kodwa zikwindawo enomtsalane kubakhenkethi evelisa ingeniso yezigidi zeedola. Ngokwembono yendalo, iyasikhusela kwizikhukula, iitsunami kwaye inegalelo kukhuseleko lokutya ngokuloba. Kuya kufuneka sazi ukuba uninzi lweziyobisi ze-anticancer zitsalwa kwiingqaqa zekorale.

Kufuneka sazi ukuba ziindawo zokuhlala zendalo ezisengozini ezinjengeentsiba zaselwandle, ii-anemones, ii-gorgoni, phakathi kwabanye. Ingxelo ye-UNEP ikwaqaqambisa ukubaluleka kweekorale kuqoqosho lwaseMesoamerica naseIndonesia, imimandla emibini ethi Ngaphezulu kwe-34.000 yeebhiliyoni zeedola nganye inokufakwa phakathi namhlanje ukuya ku-2030 ukuba siphucula impilo yamatye.

Ndiyathemba ukuba ngolu lwazi ungafunda ngakumbi malunga noLwandle lweCoral kunye neempawu zalo.
