Una Umkhomo we-humpback uvaleleke oLwandle iBaltic Kugcine iziphathimandla, ochwepheshe, kanye nezakhamuzi zasenyakatho yeJalimane zikhathazekile izinsuku eziningana. Le nhlanzi enkulu yabhajwa emanzini angajulile ogwini lwaseTimmendorfer Strand, eLübeck Bay, okwabangela umsebenzi wokuhlenga oyinkimbinkimbi, wokuncintisana nesikhathi.
Nakuba umkhomo ekugcineni ukwazile phumula esihlabathini bese uqonda olwandle oluvulekileOchwepheshe bagcizelela ukuthi lesi silwane sisesimeni esibucayi. Ukuze umsebenzi ubhekwe njengempumelelo yangempela, kusadingeka sihambe amakhulu amakhilomitha ukuze sifike lapho siya khona. uLwandle lwaseNyakatho, futhi kusukela lapho, amanzi ase-Atlantic, uhambo olungelula neze kumuntu osevele ebuthakathaka.
Iphi futhi kanjani i-humpback whale ebanjwe kuyo
Lesi silwane saqala ukubonwa ngoMsombuluko ekuseni, izinze ogwini lwesihlabathi esingaphansi kwamanzi ngase-Timmendorfer StrandUmkhomo utholakale endaweni ejule ngamamitha amabili kuphela, indawo ethandwa kakhulu yizivakashi esifundazweni saseSchleswig-Holstein, enyakatho yeJalimane. Amanzi ayengafaneleki nhlobo esilwaneni esilingana nawo.
Ngokwemininingwane enikezwe amaqembu okutakula kanye nososayensi bezinto eziphilayo zasolwandle, kungenzeka ukuthi insizwa ephakathi kwamamitha ayi-10 kuya kwangu-15 ubudeNjengoba inesisindo samathani amaningana, ochwepheshe basikisela ukuthi kungenzeka ukuthi iyisibonelo esifanayo esibonwe emasontweni amuva nje echwebeni laseWismar, nalo ogwini lwaseBaltic lwaseJalimane, okusho ukuthi ibilokhu izulazula kule ndawo isikhathi esithile.
Imikhomo ye-humpback ayiyona izinhlobo ezivamile zoLwandle iBalticUlwandle i-Atlantic luwulwandle olungaphakathi olunezici ezihluke kakhulu kune-Atlantic: amanzi angajulile, usawoti onciphile, kanye nokungabi namagagasi abalulekile. Konke lokhu kusho ukuthi uma i-cetacean enkulu isondela ogwini eduze kakhulu noma iphazamiseka, kungenzeka kakhulu ukuthi ivaleleke.
Isizathu esiqondile sokuthi kungani lesi silwane sigcine sibhajwe asikacaci. Ochwepheshe bacabangela imibono eminingana: ukudideka ngesikhathi sokufuduka, ukuhlukunyezwa ngamabhange de peces ezindaweni ezingajulile, ukuphazamiseka okungenzeka kwe-acoustic endaweni yasolwandle noma ngisho nokuba buthaka kwangaphambilini ngenxa yezifo noma ukusebenzisana nemishini yokudoba.
Ngesikhathi sokutholakala kwawo, umkhomo wethula izinsalela zenetha lokudoba zibambeke emzimbeni wakheabahlengi abakwazile ukunquma. Lokhu okutholakele kuqinisa ukusola ukuthi lesi silwane kungenzeka ukuthi sabhekana nezinkinga ezihlobene nokudoba ngaphambi kokuba sibhajwe.
Imizamo yokuqala yokutakula: izikebhe, amaza okwenziwa kanye nama-drone
Lapho nje sekuqinisekisiwe ukuthi lesi silwane sikhona, iziphathimandla zendawo kanye nezinsizakalo eziphuthumayo eLübeck Basebenzisa ithuluzi elikhethekile. Inhloso yokuqala yayilula ngokwemfundiso kodwa iyinkimbinkimbi ngokwezenzo: ukwenza umkhomo ufinyelele endaweni ejulile ngokwawo.
NgoMsombuluko ntambama, okulandelayo kwenzeke ukuhamba ngezikebhe zamaphoyisa, izikebhe ezifuthwayo kanye namayunithi onogada basogwiniImikhumbi yadlula eduze kwe-cetacean, yakha amagagasi amakhulu ngethemba lokuthi amandla amanzi azosiza ukuyikhipha ebhange lesihlabathi.
Lo msebenzi wawuhilelekile futhi amadroni abacimi bomliloBandiza phezu kwendawo ukuze banikeze izithombe zasemoyeni futhi basize ekuhleleni ukunyakaza kwemikhumbi. Umqondo kwakuwukusebenzisa noma yiluphi ushintsho oluncane ezingeni lolwandle ukuze kube lula ngesilwane ukujika nokungena emanzini ajulile.
Naphezu kwale mizamo, isimo asizange sibe ngcono kangako. Amaqembu okutakula aqale akwazile ukuxazulula le nkinga. Phendula umkhomo ukuze ikhanda lawo libheke olwandle oluvulekileLokhu kwabhekwa njengokuthuthuka okukhulu. Kodwa-ke, lesi silwane sabuyela ngokushesha endaweni yaso yokuqala, saphinde sabhajwa esihlabathini.
Enye yezinkinga ezinkulu ngalo msebenzi kwakuyi- ukungabikho kwamagagasi amakhulu oLwandle iBalticNgokungafani nalokho okwenzeka e-Atlantic, ukujiya kwezinga lamanzi kulinganiselwe kakhulu, ngakho-ke ukwenyuka kwamagagasi akunakwethenjelwa kuphela ukusiza i-cetacean ukuba intante futhi izikhulule.
Okwamanje, ochwepheshe abavela ezinhlanganweni ezikhethekile ezifana UMelusi Wasolwandle kanye nososayensi abavela Isikhungo Socwaningo Ngezilwane Zasemhlabeni Nasemanzini (ITAW) Bahamba baya eTimmendorfer Strand ukuyohlola isimo sesilwane futhi banikeze iseluleko ngezinyathelo ezilandelayo. Ngokusho kofakazi, umkhomo wawusaphila: wawuphefumula, wenza imisindo, futhi ngezinye izikhathi uphakamisa ikhanda lawo, okubonisa ukuthi wawusenamandla, kodwa isimo sawo sasiwohloka ngomzuzu.
Ithuluzi lokutakula eliyinkimbinkimbi ngokwengeziwe
Ngenxa yokuntuleka kwemiphumela yemizamo yokuqala, iziphathimandla zanquma qinisa ukusebenza futhi wengeze izinsiza ezintshaKwahlelwa izinhlelo ezintsha ngoLwesibili nangoLwesine, ngendlela yokuncintisana nesikhathi ukuvimbela lesi silwane ukuba singafi ogwini lolwandle.
Labo ababenesibopho salolu cingo baphikelela ukuthi Kwakungenakwenzeka ukudonsa umkhomo ngqo Ukumbopha ngezintambo noma ama-harnesses kwakubaluleke kakhulu, njengoba lokhu kwakungabangela ukulimala okukhulu kwangaphakathi noma ukulimala kwamaphiko akhe nomgogodla. Noma yikuphi ukujika kwakudingeka kunciphise ingozi yokulimala okuqhubekayo.
Ngesikhathi esifanayo, amaphoyisa aqhubeka vala izindawo ezinkulu zolwandle ngocingo ukugcina ababukeli bekude. Ukuba khona okukhulu kwezivakashi nabantu abathintekile yilesi simo kungadala ukucindezeleka okwengeziwe kulesi silwane, esasivele sisesimweni esibucayi.
Abakhulumeli bamaphoyisa bakhumbuza wonke umuntu ngokuphindaphindiwe ukuthi Kwakubalulekile ukungakhulisi izinga lokucindezeleka kwe-cetaceanUmphakathi wacelwa ukuba ugcine ibanga lokuxhumana nabantu, ugweme umsindo ongadingekile, futhi uhloniphe imiyalelo yabasebenzi. Naphezu kwale mikhawulo, abantu abaningi abadlulayo basondela ukuzobona bekude, abaningi babo bethinteke kakhulu ukubona umkhomo uvaleleke eduze nogu.
Izakhamuzi zasedolobheni eliseduze, njengeScharbeutz, zibike ukuthi zazinakho Ngikwazile ukuzwa imisindo yomkhomo ebusukuenethemba lokuthi ukushintshashintsha kwezinga lamanzi kuzomsiza ukuba akhululeke, into eyenzeka ngokungazelelwe ekugcineni.
Abavubukuli kanye nemigodi yokuvula indlela eya enkululekweni
Ngenxa yokuqhubeka kwenkinga kanye nokuwohloka kancane kancane kwesimo somkhomo, kwakhethwa isu elinamandla kakhulu ngoLwesine: ulethe imishini yokumba kanye nemishini esindayo endaweni ukushintsha indlela isilwane esasivaleleke ngayo.
Abahlengi kanye nochwepheshe basebenze ne ama-bulldozer, ama-excavator kanye nama-dredge ukuvula uhlobo oluthile lomsele noma umsele esihlabathini esiphambi kwekhanda lomkhomo. Umgomo kwakuwukudala indlela ejulile ngokwanele ukuze, lapho izinga lamanzi likhuphuka kancane, umkhomo ukwazi ukubhukuda uye phambili ushiye isicupho sesihlabathi ngemuva.
Isazi sezinto eziphilayo zasolwandle URobert Marc Lehmann Wayeqondisa le misebenzi eduze, eqondisa ukubekwa kwemishini kanye nokuphepha kwesilwane. Phakathi naleso sikhathi, umbhukudi wayephethe mbonise indlela kuya e-cetacean ngaphansi kwamanzi, okubonisa indlela yomsele osanda kumbiwa.
Umsebenzi waqhubeka isikhathi eside kuze kube yilapho sekuhlwileKodwa kwathi sekuhlwile kwaphoqa ukuthi imisebenzi imiswe ngenxa yezizathu zokuphepha. Ngaleso sikhathi, umkhomo wawusuhambe amamitha angaba ngu-40 kuphela eceleni komzila, futhi kwakusesele amamitha ambalwa ngaphambi kokuba ufike endaweni ejulile. Naphezu kokukhathala kwabo, amaqembu anquma ukumisa imisebenzi kuze kube ngakusasa ekuseni.
Phakathi nalezo zikhathi zasebusuku ezizolile, kwenzeka lokho abahlengi ababekufisa: Umkhomo wasebenzisa ithuba lokuphunyuka elalivuleke esihlabathini futhi wakwazi ukuzikhulula eyedwa, ethuthela kude nebhange lapho ayevaleleke khona izinsuku eziningana.
Ukusuka eLübeck Bay bese uphelezela olwandle oluvulekile
Ekuseni ngoLwesihlanu ekuseni, ochwepheshe be-ITAW nabanye ochwepheshe babike ukuthi umkhomo Bekuya ngasekuphumeni kweLübeck BayLesi silwane sasiseduze nogu, cishe amamitha angu-300 ukusuka ogwini. Sasihamba kancane, kodwa ekugcineni sintanta emanzini ajulile ngokwanele.
Ukuze kuhambisane nalokhu kunyakaza nokunciphisa ingozi yokuthi i-cetacean iphinde idideke, umphelezeli wasolwandle onemikhumbi emininganaIzikebhe eziyisithupha ezivela e- I-German Coast Guard, amayunithi e- Inhlangano Yokusindisa Impilo YaseJalimane (i-DLRG) kanye nemikhumbi yokusekela enososayensi ababesesikebheni balandela umkhomo njengoba uqhubeka uya ezindaweni ezivulekile zaseBaltic.
Amaqembu azamile ngaso sonke isikhathi qondisa isilwane olwandle oluvulekileukuyisusa emabhange esihlabathi kanye namanzi angajulile ayingozi eduze nogu. Naphezu kwalokhu, labo ababephethe lo msebenzi babike ukuthi, ngesinye isikhathi kamuva, umkhomo wawusukhona ibonwe futhi eduze kwendawo lapho yayivaleleke khonaokwabonisa ukuthi kusenengozi yokuthi ilahleke.
Ukuziphatha okungaguquki kwalesi silwane akuzange kubamangaze ososayensi bezinto eziphilayo. Isampula esichithe izinsuku eziningana sibambekile, sibhekene nokucindezeleka, ukukhathala, kanye nokulimala kwangaphakathi okungenzeka, singabonisa ukudideka nokuntuleka kwamandla isikhathi eside, noma ngabe ikwazile ukuntanta futhi.
Kodwa-ke, ukuhlolwa kochwepheshe bekuqaphile kodwa kunethemba kancane: iqiniso lokuthi bazikhulule esihlabathini Kwakumele isinyathelo esibalulekile sokuqhubekela phambili, yize kwakukude kakhulu nokuqinisekisa ukuthi izosinda esikhathini esiphakathi.
Uhambo olude oluya e-Atlantic lulindele
Ngemva kokukhululwa kwayo, ukukhathazeka okukhulu kososayensi kwakuwukuthi umkhomo i-humpback, akuyona into evamile emanzini aseBalticKumelwe athole indlela efanele eya oLwandle Olusenyakatho. Ukuze enze lokhu, kumelwe ahambe amakhilomitha angamakhulu amaningana emanzini aseJalimane naseDenmark, agweme ukuhamba ngezinyawo, futhi agweme ukubuyela ezindaweni eziyisicaba eduze nogu.
Ochwepheshe abanjengoRobert Marc Lehmann baxwayise ngokuthi isivivinyo sangempela sokusinda Akukhona nje ukugwema ukunamathela kokuqala, kodwa mayelana nokuqeda lolo hambo olude oluya e-Atlantic. Kuze kube yilapho lesi silwane sishiya ngokuphelele iBaltic, ingozi yokunamathela kwesinye isilwane izohlala ikhona.
Ongoti bayakugcizelela lokho ukugoqana ngakunye kwezinyoni ezinkulu zase-cetacean eYurophu Kuyithuba lokufunda ukuziphatha kwazo, imizila ezilandela yona, kanye nezici ezingase zishintshe ukuzulazula kwazo kwemvelo, kusukela emsindweni ongaphansi kwamanzi kuya ezinguqukweni zokusabalala kwezilwane ezizidlayo.
Kulesi simo esithile, ososayensi baseJalimane kanye nezinhlangano zokulondolozwa kolwandle bahlela ukuqhubeka nokuqapha, ngangokunokwenzeka, ukuba khona komkhomo emanzini asenyakatho yeYurophu, kungakhathaliseki ukuthi ngokubona okuvela ezweni, imibiko yemikhumbi, noma idatha evela ezinhlelweni zokuqapha i-radar kanye nogu lolwandle.
Indaba yalo mkhomo i-humpback oLwandle iBaltic, enezinsuku zosizi, imishini esindayo esihlabathini, kanye nemikhumbi ephelezela lesi silwane olwandle, isibe yisikhumbuzo esicacile kakhulu. ukuthi impilo yasolwandle ingaba sengozini kangakanani uma ingcindezi yabantu olwandle ihlanganiswa nobuthakathaka obungokwemvelo bezindawo zemvelo zasogwini lwaseYurophuUmphumela wokugcina uzoxhomeka ekutheni i-cetacean iyakwazi yini ukuqeda uhambo lwayo oluya e-Atlantic, kodwa umsebenzi omkhulu oqhutshwe eJalimane wenza kucace ukuthi umphakathi waseYurophu uzimisele kangakanani ukuhlanganyela ukuze uzame ukusindisa isilwane esikhulu esisodwa esivele sivele sicela usizo ogwini.
