Kujambula kwa sonar kochitidwa ndi kafukufuku wasayansi kunavumbula kuti kusweka kwa chombo chomwe sichinadziwike kale chinapezeka mtunda wa kilomita imodzi kuchokera kugombe la North Carolina.Zomwe zidapangidwa m'sitimayo zidamira zikuwonetsa kuti zitha kuyambika ku America Revolution.
Asayansi apanyanja adapeza kuti ngalawayo idasweka paulendo wofufuza pachombo chofufuza cha Woods Hole Oceanographic Institute (WHOI) cha Atlantis pa Julayi 12.
Anapeza sitimayo itamira pamene akugwiritsa ntchito makina a WHOI a robotic automatic underwater (AUV) sentry komanso Alvin yodutsa pansi pamadzi.Gululi lakhala likuyang'ana zida zolumikizira, zomwe zidali paulendo wofufuza m'derali mu 2012.
Zotsalira zomwe zinapezedwa m’ngozi ya chombocho ndi monga maunyolo achitsulo, mulu wa matabwa a sitima yapamadzi, njerwa zofiira (mwina zochokera pamoto wa woyendetsa sitimayo), mabotolo agalasi, miphika yadothi yosawala, makampasi achitsulo, ndi mwina zida zina zowonongeka.Ndi magawo asanu ndi atatu kapena asanu ndi limodzi.
Mbiri ya kusweka kwa sitimayi ingayambike chakumapeto kwa zaka za zana la 18 kapena kuchiyambi kwa zaka za zana la 19, pamene United States wachichepere anali kukulitsa malonda ndi dziko lonse kupyolera m’nyanja.
Cindy Van Dover, mkulu wa yunivesite ya Duke ya Marine Laboratory, anati: “Ichi n’chinthu chosangalatsa kwambiri chimene atulukira komanso chikumbutso chomveka bwino chakuti ngakhale titapita patsogolo kwambiri pa luso lathu lofikira ndi kufufuza nyanja m’mikhalidwe ina, nyanja yakuya inabisanso zinsinsi zake. .”
Van Dover adati: "Ndidachitapo maulendo anayi m'mbuyomu, ndipo nthawi iliyonse ndimagwiritsa ntchito ukadaulo wofufuza zam'madzi kuti ndifufuze pansi panyanja, kuphatikiza ulendo wopita ku 2012, komwe tidagwiritsa ntchito Sentry kumizidwa ma sonar ndi zithunzi m'dera loyandikana nalo."Chodabwitsa n’chakuti tinkaganiza kuti tikuyenda patali mamita 100 kuchokera pamene ngalawa inachita ngozi ndipo sitinadziwe mmene zinthu zilili kumeneko.”
David Eggleston, mkulu wa Center for Marine Science and Technology (CMAST) anati: ).Mmodzi mwa ofufuza akuluakulu ku North Carolina State University ndi polojekiti yasayansi.
Atazindikira kuti ngalawayo inasweka, Van Dover ndi Eggstonton adadziwitsa pulogalamu ya NOAA ya zolowa m'madzi za zomwe zapezedwa.Pulogalamu ya NOAA tsopano iyesa kukonza tsikulo ndikuzindikira sitima yotayika.
Bruce Terrell, wofukula wamkulu wa Marine Heritage Project, adati ziyenera zotheka kudziwa tsiku ndi dziko lomwe sitimayo idasweka pofufuza zida zadothi, mabotolo ndi zinthu zina zakale.
Terrell anati: “Pakutentha kwapafupi ndi kuzizira, kupitirira mtunda wa kilomita imodzi kuchokera pamalowo, osasokonezedwa komanso otetezedwa bwino.”"Kafukufuku wozama wazaka zam'mabwinja m'tsogolomu angatidziwitse zambiri."
James Delgado, mkulu wa Marine Heritage Project, ananena kuti kuwonongeka kwa chombocho kumayenda m’mphepete mwa nyanja, ndipo nyanja ya Gulf of Mexico yakhala ikugwiritsidwa ntchito kwa zaka mazana ambiri ngati msewu waukulu wopita ku madoko a kumpoto kwa America, ku Caribbean. Gulf of Mexico ndi South America.
Iye anati: “Kupeza kumeneku n’kosangalatsa, koma osati kosayembekezereka.”"Mphepo yamkuntho inachititsa kuti zombo zambiri zigwe m'mphepete mwa nyanja ya Carolina, koma chifukwa cha kuya komanso kuvutika kwa ntchito kumadera akumidzi, anthu ochepa adapeza."
A Sentinel atazindikira kuti pali mzere wakuda komanso mdima wandiweyani, a Bob Waters a bungwe la WHOI anam'tengera Alvin kumalo kumene kunasweka sitima, kumene ankakhulupirira kuti n'kogwirizana ndi sayansi Zomwe zidasokonekera.Bernie Ball waku Duke University ndi Austin Todd (Austin Todd) waku North Carolina State University adakwera Alvin ngati owonera asayansi.
Cholinga cha kafukufukuyu ndikufufuza zachilengedwe za kutayikira kwa methane munyanja yakuya kugombe lakummawa.Van Dover ndi katswiri wa zamoyo zam'nyanja zakuya zomwe zimayendetsedwa ndi chemistry osati kuwala kwa dzuwa.Eggleston adaphunzira za chilengedwe cha zamoyo zomwe zimakhala pansi panyanja.
Van Dover adati: "Zomwe tapeza mosayembekezereka zikuwonetsa mapindu, zovuta komanso kusatsimikizika kwakugwira ntchito m'nyanja yakuya."“Tidazindikira kuti ngalawayo itasweka, koma chodabwitsa n’chakuti zida zomangira zomwe zidasoweka sizinapezeke.”
