Kev soj ntsuam sonar los ntawm kev tshawb fawb tshawb fawb qhia tias lub nkoj puas ntawm lub nkoj tsis paub yav dhau los tau pom ib mais tob ntawm ntug dej hiav txwv North Carolina.Cov khoom pov thawj ntawm lub nkoj sunken qhia tias nws tuaj yeem taug qab rov qab mus rau Asmeskas Kev Tawm Tsam.
Cov kws tshawb fawb hauv tubrog nkoj tau tshawb pom lub nkoj poob thaum lub sijhawm tshawb fawb ntog hauv Woods Hole Oceanographic Institute (WHOI) tshawb fawb nkoj Atlantis thaum Lub Xya Hli 12.
Lawv pom lub nkoj sunken thaum siv WHOI tus neeg hlau tsis siv neeg lub tsheb hauv qab dej (AUV) sentry thiab manned submersible Alvin.Pab neeg no tau nrhiav cov khoom siv mooring, uas tau mus tshawb fawb hauv cheeb tsam hauv xyoo 2012.
Relics pom nyob rau hauv lub wreckage ntawm lub nkoj wreck muaj xws li hlau chains, ib pawg ntawm cov ntoo nkoj cav ntoo, liab cib (tej zaum los ntawm tus thawj coj lub hearth), iav fwj, unglazed av nplaum lauj kaub, hlau compasses, thiab tejzaum nws puas lwm yam khoom siv navigation.Nws yog yim lub quarter lossis rau lub quarters.
Cov keeb kwm ntawm lub nkoj tawg tuaj yeem taug qab mus rau qhov kawg ntawm lub xyoo pua 18th lossis thaum pib ntawm lub xyoo pua 19th, thaum cov tub ntxhais hluas Asmeskas tau nthuav dav kev lag luam nrog lwm lub ntiaj teb los ntawm hiav txwv.
Cindy Van Dover, tus thawj coj ntawm Duke University's Marine Laboratory, tau hais tias: "Qhov no yog qhov kev tshawb pom zoo siab thiab kev ceeb toom tiag tiag tias txawm tias tom qab peb tau ua tiav tseem ceeb hauv peb lub peev xwm los mus txog thiab tshawb xyuas dej hiav txwv raws li qhov xwm txheej, dej hiav txwv tob kuj zais nws cov lus zais. ”
Van Dover tau hais tias: "Kuv tau ua plaub qhov kev mus ncig ua ntej, thiab txhua zaus kuv siv thev naus laus zis tshawb fawb txog dej hiav txwv, suav nrog kev ntoj ke mus rau xyoo 2012, uas peb siv Sentry los raus sonar thiab cov duab thaij duab rau hauv thaj chaw nyob sib ze."Qhov tsis txaus ntseeg yog tias peb xav tias peb tab tom tshawb nrhiav hauv 100 meters ntawm qhov chaw nkoj nkoj thiab tsis pom qhov xwm txheej nyob ntawd. "
David Eggleston, tus thawj coj ntawm Lub Chaw rau Marine Science thiab Technology (CMAST) tau hais tias "Qhov kev tshawb pom no qhia txog tias cov thev naus laus zis tshiab uas peb tab tom tsim rau kev tshawb nrhiav hauv av dej hiav txwv tob tsis yog tsim cov ntaub ntawv tseem ceeb ntawm dej hiav txwv, tab sis kuj tsim cov ntaub ntawv hais txog peb keeb kwm," ) .Ib qho ntawm cov kws tshawb fawb tseem ceeb ntawm North Carolina State University thiab qhov project scientific.
Tom qab nrhiav pom lub nkoj tawg, Van Dover thiab Eggstonton tau ceeb toom NOAA cov cuab yeej cuab tam hauv hiav txwv ntawm qhov kev tshawb pom.NOAA txoj haujlwm tam sim no yuav sim kho hnub thiab txheeb xyuas lub nkoj ploj.
Bruce Terrell, tus thawj kws tshawb fawb keeb kwm ntawm Marine Heritage Project, tau hais tias nws yuav tsum muaj peev xwm txiav txim siab hnub tim thiab lub tebchaws ntawm lub tebchaws ntawm lub nkoj tawg los ntawm kev tshuaj xyuas ceramics, fwj thiab lwm yam khoom qub.
Terrell tau hais tias: "Thaum qhov kub nyob ze rau qhov khov, ntau tshaj li ib mais deb ntawm qhov chaw, tsis muaj kev cuam tshuam thiab khaws cia zoo.""Kev tshawb fawb archaeological loj yav tom ntej tuaj yeem muab cov ntaub ntawv ntxiv rau peb."
James Delgado, tus thawj coj ntawm Marine Heritage Project, tau taw qhia tias qhov kev puas tsuaj ntawm lub nkoj tawg tau taug kev raws ntug dej hiav txwv, thiab Gulf of Mexico ntug dej hiav txwv tau siv ntau pua xyoo ua txoj kev loj hauv hiav txwv mus rau North American ports, Caribbean, Gulf of Mexico thiab South America.
Nws hais tias: "Qhov kev tshawb pom no zoo siab heev, tab sis tsis xav txog.""Lub cua daj cua dub ua rau muaj ntau lub nkoj ntog tawm ntawm ntug dej hiav txwv ntawm Carolina, tab sis vim qhov tob thiab nyuaj ntawm kev ua haujlwm nyob rau hauv ib puag ncig sab nraud, tsawg tus neeg pom nws."
Tom qab Sentinel's sonar scanning system tau kuaj pom kab dub thiab thaj chaw tsaus nti, Bob Waters ntawm WHOI tsav Alvin mus rau qhov chaw tshiab shipwreck nrhiav pom, uas lawv ntseeg tias yuav yog kev tshawb fawb mooring Dab tsi cov cuab yeej tsis muaj.Duke University's Bernie Ball thiab North Carolina State University's Austin Todd (Austin Todd) tau tsa Alvin ua tus saib xyuas kev tshawb fawb.
Lub hom phiaj ntawm qhov kev tshawb nrhiav no yog tshawb nrhiav ecology ntawm methane to hauv dej hiav txwv tob ntawm ntug dej hiav txwv sab hnub tuaj.Van Dover yog tus kws tshaj lij hauv ecology ntawm kev sib sib zog nqus dej hiav txwv ecosystems uas tau tsav los ntawm chemistry es tsis yog hnub ci.Eggleston tau kawm txog ecology ntawm cov kab mob uas nyob ntawm ntug hiav txwv.
Van Dover tau hais tias: "Peb qhov kev tshawb pom tsis txaus ntseeg qhia txog cov txiaj ntsig, kev nyuaj thiab tsis paub tseeb ntawm kev ua haujlwm hauv hiav txwv tob.""Peb nrhiav pom lub nkoj tawg, tab sis qhov tsis txaus ntseeg, cov khoom siv caij nkoj uas ploj lawm yeej tsis pom.”
