Isuzuma rya sonar ryakozwe n’ubushakashatsi bwakozwe na siyansi ryerekanye ko ibisigazwa by’ubwato bwari butaramenyekana byabonetse ku kirometero kimwe uvuye ku nkombe za Carolina y'Amajyaruguru.Ibicuruzwa biri mu bwato bwarohamye byerekana ko bishobora guturuka kuri Revolution y'Abanyamerika.
Ku ya 12 Nyakanga, abahanga mu nyanja bavumbuye ubwato bwarohamye mu gihe cy’ubushakashatsi bwakozwe mu bwato bw’ubushakashatsi bwa Woods Hole Oceanographic Institute (OMS) bwitwa Atlantis.
Basanze ubwato bwarohamye mu gihe bakoresheje imodoka ya robotike ya OMS yo mu mazi (AUV) yoherejwe na Alvin yo mu mazi.Iri tsinda ryashakishaga ibikoresho byo gutembera, byari mu rugendo rw’ubushakashatsi muri ako gace mu 2012.
Ibisigisigi biboneka mu bisigazwa by'ubwato bwarimo ubwato burimo iminyururu y'icyuma, ikirundo cy'ibiti by'ubwato bw'imbaho, amatafari atukura (birashoboka ko yaturutse ku ziko rya capitaine), amacupa y'ibirahure, inkono y'ibumba idacometse, ibyuma bya kompas, kandi birashoboka ko byangiritse Ibindi bikoresho byo kugenda.Ni kimwe cya kane cyangwa ibihembwe bitandatu.
Amateka y’ubwato bushobora kuboneka guhera mu mpera z'ikinyejana cya 18 cyangwa mu ntangiriro z'ikinyejana cya 19, igihe Amerika yari ikiri muto yaguraga ubucuruzi hamwe n'isi yose binyuze mu nyanja.
Cindy Van Dover, ukuriye Laboratoire ya Marine ya kaminuza ya Duke, yagize ati: “Ibi ni ibintu byavumbuwe bishimishije kandi byibutsa ko na nyuma yo gutera intambwe igaragara mu bushobozi bwacu bwo kwegera no gucukumbura inyanja Mu bihe, inyanja nini na yo yahishe amabanga yayo. . ”
Van Dover yagize ati: “Nigeze gukora ingendo enye mbere, kandi buri gihe nakoresheje ikoranabuhanga mu bushakashatsi bwo kwibira kugira ngo ndebe ku nyanja, harimo n'urugendo rwakozwe mu mwaka wa 2012, aho twakoresheje Sentry mu kwibiza sonar n'amashusho mu mafoto mu gace duturanye.”Igitangaje ni uko twatekereje ko turi gukora ubushakashatsi muri metero 100 uvuye aho ubwato bwarohamye kandi ntitwasanze aho ibintu bimeze. ”
Umuyobozi w'ikigo gishinzwe ubumenyi n'ikoranabuhanga mu nyanja (CMAST), David Eggleston yagize ati: "Ubu buvumbuzi bwerekana ko ikoranabuhanga rishya dutezimbere mu gushakisha inyanja y’inyanja ridatanga amakuru y'ingenzi ku nyanja gusa, ahubwo ritanga n'amakuru ku mateka yacu." ).Umwe mu bashakashatsi nyamukuru muri kaminuza ya leta ya Carolina y'Amajyaruguru n'umushinga w'ubumenyi.
Nyuma yo kuvumbura ubwato, Van Dover na Eggstonton bamenyesheje gahunda y’umurage wo mu nyanja wa NOAA.Gahunda ya NOAA noneho izagerageza gukosora itariki no kumenya ubwato bwatakaye.
Bruce Terrell, umuhanga mu bucukumbuzi bw'ibyataburuwe mu matongo mu mushinga w'umurage wo mu nyanja, yavuze ko bigomba gushoboka kumenya itariki n'igihugu byaturutseho ubwo bwato bwasenyutse hifashishijwe gusuzuma ububumbyi, amacupa n'ibindi bihangano.
Terrell yagize ati: “Ku bushyuhe buri hafi yo gukonja, kurenga kilometero imwe uvuye aho hantu, nta nkomyi kandi bibitswe neza.”“Ubushakashatsi bukomeye bw'ibyataburuwe mu bihe biri imbere burashobora rwose kuduha amakuru menshi.”
James Delgado, umuyobozi w’umushinga w’umurage wo mu nyanja, yagaragaje ko ibisigazwa by’ubwato bw’ubwato bigenda ku mugezi w’inyanja, kandi ku nkombe z’ikigobe cya Mexico bimaze imyaka amagana bikoreshwa nk'umuhanda wo mu nyanja ugana ku byambu byo muri Amerika y'Amajyaruguru, Karayibe, Ikigobe cya Mexico na Amerika y'epfo.
Yavuze ati: “Ubu buvumbuzi burashimishije, ariko ntibutunguranye.”Ati: “Inkubi y'umuyaga yatumye amato menshi agwa ku nkombe za Carolina, ariko kubera ubujyakuzimu ndetse n'ingorane zo gukorera mu nyanja, abantu bake ni bo babibonye.”
Sisitemu yo gusikana sonar ya Sentinel imaze kubona umurongo wumukara hamwe n’ahantu hijimye, Bob Waters wo muri OMSI yajyanye Alvin ahantu haherutse kuvumburwa n’ubwato, bakeka ko bushobora kuba ari ubumenyi bwa siyansi Ibyo bikoresho bidafite.Bernie Ball wo muri kaminuza ya Duke na Austin Todd wo muri kaminuza ya Leta ya Carolina y'Amajyaruguru (Austin Todd) binjiye muri Alvin nk'indorerezi za siyansi.
Iperereza ryibanzeho ni ugushakisha ibidukikije bitemba metani mu nyanja ndende ku nkombe y’iburasirazuba.Van Dover ninzobere mubidukikije bwibinyabuzima byimbitse-nyanja itwarwa na chimie kuruta izuba.Eggleston yize ku bidukikije ibinyabuzima byo ku nyanja.
Van Dover yagize ati: “Ubuvumbuzi bwacu butunguranye bwerekana inyungu, imbogamizi no gushidikanya gukorera mu nyanja ndende.”Ati: "Twabonye ubwato bwarohamye, ariko igitangaje ni uko ibikoresho byabuze byigeze biboneka.”
