Sonar scan nerwendo rwesainzi yakaratidza kuti kupunzika kwechikepe chakapunzika kwaimbozivikanwa kwakawanikwa kiromita imwe pakadzika pamhenderekedzo yeNorth Carolina.Zvigadzirwa zviri mungarava yakanyura zvinoratidza kuti inogona kuteverwa kumashure kweAmerican Revolution.
Masayendisiti emugungwa akawana chikepe chakapunzika panguva yekutsvagisa muchikepe cheWoods Hole Oceanographic Institute (WHOI) yeAtlantis musi waChikunguru 12.
Vakawana ngarava yakanyura vachishandisa WHOI's robhoti otomatiki yepasi pemvura mota (AUV) sentry uye manned submersible Alvin.Chikwata ichi changa chichitsvaga michina yekumisa, iyo yanga iri parwendo rwekutsvaga munzvimbo iyi muna 2012.
Zvisaririra zvakawanikwa pakaputsika ngarava yacho zvinosanganisira cheni dzesimbi, murwi wematanda ematanda engarava, zvidhinha zvitsvuku (zvichida zvinobva pachoto chakaputeni), mabhodhoro egirazi, hari dzevhu dzisina kupenya, kambasi dzesimbi, uye zvimwe zvakakuvadzwa Zvimwe zvokushandisa pakufambisa ngarava.Zvikamu zvisere kana zvitanhatu.
Nhau yokuputsika kwengarava inogona kurondwa shure kusvikira kumugumo wezana ramakore rechi 18 kana kuti kutanga kwezana ramakore rechi 19, apo United States yechiduku yakanga ichiwedzera kutengeserana nedzimwe nyika nomugungwa.
Cindy Van Dover, mukuru weDuke University's Marine Laboratory, akati: “Ichi chiwanwa chinofadza uye chiyeuchidzo chakajeka chokuti kunyange pashure pokunge tafambira mberi zvikuru mukukwanisa kwedu kusvika nokunzvera gungwa Mumamiriro ezvinhu, gungwa rakadzika rakavanzawo zvakavanzika zvaro. .”
Van Dover akati: "Ndakamboita nzendo ina kare, uye nguva imwe neimwe yandaishandisa tekinoroji yekunyura kuti ndiongorore pasi pegungwa, kusanganisira rwendo muna 2012, kwatakashandisa Sentry kunyudza sonar nemifananidzo munzvimbo yakavakidzana."Zvinoshamisa ndezvekuti takafunga kuti tiri kuongorora mukati me100 metres kubva panzvimbo yakaputsikirwa nechikepe uye hatina kuwana mamiriro ezvinhu ipapo. "
"Kuwanikwa uku kunoratidza kuti tekinoroji nyowani yatiri kugadzira yekuongorora pasi pegungwa yakadzika haingobudisi ruzivo rwakakosha pamusoro pegungwa, asi zvakare inoburitsa ruzivo nezvenhoroondo yedu," akadaro David Eggleston, director weCentre for Marine Science and Technology (CMAST). ) .Mumwe wevaongorori vakuru kuNorth Carolina State University uye chirongwa chesainzi.
Mushure mekuona kuparara kwechikepe, Van Dover naEggstonton vakazivisa NOAA's marine heritage program nezve kuwanikwa.Iyo NOAA chirongwa chave kuyedza kugadzirisa zuva uye kuona ngarava yakarasika.
Bruce Terrell, mukuru wezvokuchera matongo weMarine Heritage Project, akati zvinofanirwa kuitika kuona zuva nenyika yekwakabva ngarava yakaparara nekuongorora makeramiki, mabhodhoro nezvimwe zvinhu.
Terrell akati: “Pane tembiricha iri pedyo nechando, inopfuura kiromita imwe chete kubva panzvimbo, isina kukanganiswa uye yakachengetedzwa zvakanaka.”"Ongororo yakakomba yezvokuchera matongo mune ramangwana inogona kutipa rumwe ruzivo."
James Delgado, mutungamiriri weMarine Heritage Project, akataura kuti kuputsika kwechikepe kunofamba nemubay creek, uye Gulf of Mexico mhenderekedzo yave ichishandiswa kwemazana emakore senzira huru yezvikepe inoenda kuNorth America zviteshi, Caribbean, Gulf yeMexico neSouth America.
Iye akati: "Kuwanikwa uku kunonakidza, asi hazvitarisirwe.""Dutu iri rakaita kuti nhamba huru yezvikepe zvidonhe kubva kumhenderekedzo yeCarolina, asi nekuda kwekudzika uye kuoma kwekushanda kune imwe nzvimbo yegungwa, vashomanana vakaiwana."
Mushure mekunge Sentinel's sonar scanning system yaona mutsara mutema nenzvimbo ine rima, Bob Waters weWHOI akatyaira Alvin kunzvimbo ichangobva kuwanikwa yakaputsikirwa nechikepe, yavaitenda kuti ingangove yekumisikidza kwesainzi Izvo zvisina mudziyo.Duke University's Bernie Ball uye North Carolina State University's Austin Todd (Austin Todd) vakakwira Alvin sevacherechedzi vesainzi.
Chinangwa cheongororo iyi ndechekuongorora ecology yekudonha kwemethane mugungwa rakadzika pamhenderekedzo yekumabvazuva.Van Dover inyanzvi mune ecology yezvakadzika-gungwa ecosystems inofambiswa nekemesitiri kwete chiedza chezuva.Eggleston akadzidza ecology yezvipenyu zvinogara pasi pegungwa.
Van Dover akati: "Zvatisingatarisirwi zvatakawana zvinoratidza mabhenefiti, matambudziko uye kusava nechokwadi kwekushanda mukati megungwa."“Takawana chikepe chacho chaparara, asi zvinotoshamisa ndezvokuti, midziyo yokusungirira yakanga isipo haina kumbowanikwa.”
