Sawirka Sonar-ka oo lagu sameeyay sahan cilmiyaysan ayaa daaha ka qaaday in burburka doon aan hore loo aqoonin laga helay meel hal mayl u jirta xeebta North Carolina.Aasaaska markabka quusay ayaa tilmaamaya in laga yaabo in laga soo bilaabo Kacaankii Mareykanka.
Saynis yahanada badda ayaa helay doonida burburtay intii lagu guda jiray baaritaan cilmi baaris ah oo ay ku jireen markabka cilmi baarista ee Woods Hole Oceanographic Institute (WHOI) ee Atlantis bishii Luulyo 12-keedii.
Waxay heleen markabkii go'ay iyaga oo isticmaalayay WHOI's robotic automatic gaadhi hoostooda (AUV) iyo cidiyaha Alvin.Kooxdu waxa ay raadinaysay qalabka lagu xidho, kaas oo safar cilmi baadhis ah ugu maqnaa deegaanka 2012kii.
Waxyaabaha laga helay burburka markabka burburay waxaa ka mid ah silsilado bir ah, tuulan alwaax markab alwaax ah, leben guduudan (laga yaabo inay ka soo jeedaan qolka kabtanka), dhalooyinka dhalada ah, dhoobada dhoobada ah ee aan muraayadaha lahayn, compassyada biraha ah, iyo suurtogalnimada inay waxyeelo soo gaarto qalabka kale ee socodka.Waa siddeed rubuc ama lix rubuc.
Taariikhda burburka markabkan ayaa laga soo xigtay dhamaadkii qarnigii 18-aad ama bilawgii qarnigii 19-aad, markaas oo dalka Maraykanka da'da yar uu balaadhinayay ganacsiga uu la wadaago caalamka intiisa kale isaga oo adeegsanaya badda.
Cindy Van Dover, oo madax ka ah shaybaadhka badda ee Jaamacadda Duke, ayaa tidhi: "Tani waa daahfurka xiisaha leh iyo xasuusin cad in xitaa ka dib markii aan horumar la taaban karo ka samaynay awooddeena aan ugu dhowaanno oo aan sahamino badda Marka ay jiraan duruufo, badda moolku waxay sidoo kale qarisay sirteeda. .”
Van Dover wuxuu yiri: "Waxaan horay u sameeyay afar safar, mar kasta oo aan isticmaalay tignoolajiyada cilmi-baarista quusinta si aan u sahamiyo badda dhexdeeda, oo ay ku jirto socdaal 2012, halkaas oo aan u isticmaalnay Sentry si aan u galno sawirada sonar iyo sawirada aagga deriska ah."Arinta yaabka leh ayaa ah in aanu u malaynay in aanu baadhnay meel 100 mitir u jirta goobta uu markabku ku burburay oo aanu ogaanay xaalada halkaas ka jirta”.
"Daahfurkani wuxuu iftiiminayaa in tignoolajiyada cusub ee aan u horumarinayno sahaminta sagxada qoto dheer ee badda ma aha oo kaliya inay abuurto macluumaad muhiim ah oo ku saabsan badda, laakiin sidoo kale waxay abuurtaa macluumaadka ku saabsan taariikhdeena," ayuu yiri David Eggleston, oo ah agaasimaha Xarunta Sayniska iyo Teknolojiyada Badda (CMAST). ) .Mid ka mid ah cilmi-baarayaasha maamulaha ee North Carolina State University iyo mashruuca sayniska.
Ka dib markii ay ogaadeen burburka markabka, Van Dover iyo Eggstonton waxay ogeysiiyeen barnaamijka hiddaha badda ee NOAA ee helitaanka.Barnaamijka NOAA wuxuu hadda isku dayi doonaa inuu hagaajiyo taariikhda oo uu aqoonsado markabka lumay.
Bruce Terrell, oo ah madaxa cilmi-baarista qadiimiga ah ee Mashruuca Dhaxalka Badda, ayaa sheegay in ay suurtagal tahay in la ogaado taariikhda iyo dalka uu ka yimid markabka burburay iyadoo la baarayo dhoobada, dhalooyinka iyo agabyada kale.
Terrell wuxuu yiri: "Xilkulka u dhow inuu qaboojiyo, in ka badan mayl u jirta goobta, aan qasnayn oo si wanaagsan loo ilaaliyo.""Daraasad qadiimi ah oo halis ah mustaqbalka ayaa hubaal na siin karta macluumaad dheeraad ah."
James Delgado, oo ah agaasimaha Mashruuca Dhaxalka Badda, ayaa tilmaamay in burburka markabka burburay uu ku socdo qulqulka gacanka, iyo Gacanka Mexico ayaa loo isticmaali jiray boqolaal sano oo ah waddo weyn oo badda ah oo loo maro dekedaha Waqooyiga Ameerika, Kariibiyaanka, Gacanka Mexico iyo Koonfurta Ameerika .
Waxa uu yidhi: "Daahfurkani waa mid xiiso leh, laakiin ma aha mid lama filaan ah.""Duufaantu waxay sababtay in tiro badan oo maraakiib ah ay ku soo dhacaan xeebaha Carolina, laakiin qoto dheer iyo dhibaatada ka shaqeynta jawiga xeebaha awgeed, dad yar ayaa helay."
Ka dib markii Sentinel's sonar scanning system uu ogaaday khad madow iyo meel mugdi ah oo fidsan, Bob Waters oo ka tirsan WHO ayaa u kaxeeyay Alvin goobta cusub ee doonta burburtay, taas oo ay rumaysnaayeen in laga yaabo in ay tahay mooryaan cilmiyeed Maxaa qalabku ka maqan yahay.Bernie Ball ee Jaamacadda Duke iyo Austin Todd (Austin Todd) ee Jaamacadda Gobolka North Carolina ayaa Alvin u raacay kormeerayaal saynis ah.
Ujeeddada baaritaankan ayaa ah in la sahamiyo bay'ada ka soo rogmada methane ee badda moolka dheer ee xeebta bari.Van Dover waa khabiir ku takhasusay cilmiga deegaanka ee hab-nololeedyada badda mool-dheer ee ay wadaan kimistari halkii ay ka ahaan lahaayeen iftiinka qorraxda.Eggleston wuxuu bartay cilmiga bay'ada noolaha ee ku nool sagxada badda.
Van Dover wuxuu yiri: "Baahintayada lama filaanka ah waxay muujineysaa faa'iidooyinka, caqabadaha iyo hubanti la'aanta ka shaqeynta badda moolka.""Waan ogaanay burburka markabka, laakiin si la yaab leh, qalabka meesha lagu dhejiyo ee maqan waligiis lama helin.”
