Ukuskena kwe-sonar ohambweni lwesayensi kwembula ukuthi ukuphahlazeka komkhumbi okungaziwa ngaphambilini kutholwe imayela elilodwa ukusuka ogwini lwaseNorth Carolina.Izinto zobuciko zomkhumbi ocwile zikhomba ukuthi zingalandelelwa emuva kuNguquko YaseMelika.
Ososayensi basolwandle bathole ukuphahlazeka komkhumbi ngesikhathi sohambo lokucwaninga esikebheni sokucwaninga saseWoods Hole Oceanographic Institute (WHOI) i-Atlantis ngoJulayi 12.
Bathole umkhumbi ocwile ngesikhathi besebenzisa umthumeli wemoto engaphansi kwamanzi ye-WHOI (i-AUV) kanye ne-Alvin ehamba ngaphansi kwamanzi.Ithimba belilokhu lithungatha amathuluzi okubopha, ebelinohambo locwaningo kule ndawo ngo-2012.
Izinsalela ezatholwa ezingozini zomkhumbi zihlanganisa amaketanga ensimbi, inqwaba yezingodo zokhuni zomkhumbi, izitini ezibomvu (mhlawumbe ezivela eziko likakaputeni), amabhodlela ezingilazi, izimbiza zobumba ezingacwebezeli, amakhampasi ensimbi, kanye nezinye izinto zokuqondisa ezicekeleke phansi okungenzeka ukuthi zazilimele.Kungamakwata ayisishiyagalombili noma ayisithupha.
Umlando wokuphahlazeka komkhumbi ungalandelelwa emuva ekupheleni kwekhulu le-18 noma ekuqaleni kwekhulu le-19, lapho intsha yase-United States yandisa ukuhweba nawo wonke umhlaba olwandle.
UCindy Van Dover, inhloko ye-Marine Laboratory yaseNyuvesi yaseDuke, uthe: “Lokhu kutholwe okujabulisayo nesikhumbuzo esicacile sokuthi ngisho nangemva kokuba sesenze intuthuko enkulu ekhonweni lethu lokusondela nokuhlola ulwandle Ngaphansi kwezimo, utwa lolwandle lubuye lwafihla izimfihlo zalo. .”
UVan Dover uthe: “Ngake ngenza izinkambo ezine ngaphambilini, futhi isikhathi ngasinye ngangisebenzisa ubuchwepheshe bokucwaninga ukutshuza ukuze ngihlole indawo engaphansi kolwandle, okuhlanganisa nohambo lwango-2012, lapho sasebenzisa khona u-Sentry ukuze sicwilise i-sonar nezithombe zezithombe endaweni engumakhelwane.”Okuxakayo ukuthi besicabanga ukuthi besihlola endaweni engamamitha angu-100 ukusuka lapho kuphahlazeke khona umkhumbi futhi asizange sisithole isimo lapho.”
“Lokhu okutholakele kugqamisa ukuthi ubuchwepheshe obusha esibuthuthukisayo bokuhlola indawo ekujuleni kolwandle abukhiqizi nje kuphela ulwazi olubalulekile ngolwandle, kodwa futhi bukhiqiza ulwazi ngomlando wethu,” kusho uDavid Eggleston, umqondisi weCentre for Marine Science and Technology (CMAST). ).Omunye wabacwaningi abakhulu eNyuvesi yaseNorth Carolina State kanye nephrojekthi yesayensi.
Ngemva kokuthola ukuphahlazeka komkhumbi, u-Van Dover no-Eggstonton bazisa uhlelo lwamagugu olwandle lwe-NOAA ngokutholakala.Uhlelo lwe-NOAA manje seluzozama ukulungisa usuku nokuhlonza umkhumbi olahlekile.
UBruce Terrell, isazi semivubukulo esikhulu seMarine Heritage Project, uthe kufanele kwenzeke ukucacisa usuku kanye nezwe umkhumbi ophahlazekile owavela kuwo ngokuhlola izinto zobumba, amabhodlela nezinye izinto zobuciko.
UTerrell uthe: “Emazingeni okushisa acishe abe yiqhwa, ibanga elingaphezu kwekhilomitha ukusuka endaweni, angaphazanyiswa futhi alondolozwe kahle.”"Ucwaningo olujulile lwemivubukulo esikhathini esizayo lungasinikeza ulwazi olwengeziwe."
UJames Delgado, umqondisi we-Marine Heritage Project, waveza ukuthi izingozi zomkhumbi zihamba ngasechwebeni lomfula, futhi ugu lwaseGulf of Mexico selusetshenziswe amakhulu eminyaka njengomgwaqo omkhulu wasolwandle oya emachwebeni aseNyakatho Melika, eCaribbean, IGulf of Mexico naseNingizimu Melika.
Uthe: “Lokhu okutholakele kuyajabulisa, kodwa akulindelekile.”"Isiphepho sidale ukuthi inqwaba yemikhumbi iwe ogwini lwaseCarolina, kodwa ngenxa yokujula nobunzima bokusebenza endaweni engasogwini, bambalwa abantu abasitholile."
Ngemva kokuba isistimu yokuskena ye-sonar ye-Sentinel ithole ulayini omnyama kanye nendawo emnyama ehlakazekile, u-Bob Waters we-WHOI wayisa u-Alvin endaweni esanda kutholwa yokuphahlazeka komkhumbi, ababekholelwa ukuthi ingase ibe yindawo yesayensi yokubophela Okushodayo.UBernie Ball waseDuke University kanye no-Austin Todd (Austin Todd) waseNyuvesi yaseNorth Carolina State bagibele u-Alvin njengababukeli besayensi.
Inhloso yalolu phenyo ukuhlola i-ecology yokuvuza kwe-methane olwandle olujulile ogwini olusempumalanga.UVan Dover uchwepheshe we-ecology ye-deep-sea ecosystems eqhutshwa i-chemistry esikhundleni sokukhanya kwelanga.U-Eggleston uye wafunda i-ecology yezinto eziphilayo ezihlala phansi olwandle.
UVan Dover uthe: “Esikutholile esingakulindele kubonisa izinzuzo, izinselele nokungaqiniseki kokusebenza ekujuleni kolwandle.”“Sithole ukuthi umkhumbi uphahlazekile, kodwa okuxakayo ukuthi imishini yokubopha elahlekile ayizange itholakale.”
