Grand Canyon le New York City li tšoana ka eng?

Ka Caroline Coogan, Research Intern, The Ocean Foundation

Nako le nako ha ke etela New York ke khahloa - 'me hangata ke hlolloa - ke meaho e telele le bophelo bo phetheselang. E eme ka tlas'a moaho o molelele oa 300 m kapa e shebile mokatong oa eona oa ho shebella, toropo e ka ba moru oa litoropo o tlang ka holimo kapa toropo ea toy e benyang e benyang ka tlase. Ak'u nahane u qhoma ho tloha bophahamong ba New York City ho ea botebong ba Grand Canyon, 1800 m ho theoha.

Boholo ba limakatso tsena tse entsoeng ke batho le tsa tlhaho bo susumelitse baetsi ba litšoantšo, litsebi tsa tlhaho le bo-rasaense ka makholo a lilemo. Pontšo ea morao tjena ka Gus Petro Nahana ka toropo e lutseng har'a liphula le litlhōrō tsa Grand Canyon - empa ho thoe'ng haeba nka u bolella hore ho na le khohlo e habeli ea boholo ba eona e seng e le New York? Ha ho hlokahale photoshop mona, the Hudson Canyon e bolelele ba 740 km le botebo ba 3200 m le limaele feela ho theosa le Noka ea Hudson le ka tlas'a leoatle le leputsoa le tebileng…

Shelofo ea Mid-Atlantic e tšoailoe ka li-canyon le lithapo tsa leoatle, e 'ngoe le e 'ngoe e khahla joalo ka Grand Canyon ebile e phethesela joalo ka New York City. Mebala e khanyang le mefuta e ikhethang e tsamaisana le fuluru kapa e tsamaea botebong ba leoatle. Ho tloha Virginia ho ea New York City ho na le likhohlo tse leshome tse hlokomelehang tse tebileng tsa leoatle tse tletseng bophelo - likhohlo tse leshome tse re lebisang ho o mong oa mekete ea rona ea lilemo tse 10.

Likhohlo tse tsoang Virginia le Washington, DC - the Norfolk, Washington, 'me Accomac Lithakha - na le mehlala e meng e ka boroa ea likorale tsa metsi a batang le liphoofolo tse amanang le tsona. Likorale hangata li amahanngoa le metsi a futhumetseng, a tropike. Likorale tsa metsi a tebileng li bohlokoa haholo 'me li amohela mefuta e fapaneng ea mefuta e fapaneng joalo ka bo-motsoala ba bona ba lebōpong la leoatle. The Norfolk Canyon e 'nile ea khothaletsoa e le sebaka se sirelelitsoeng sa maoatle nako le nako, mohlala o tloaelehileng oa tsela eo re tšoarang matlotlo a rona a mose ho maoatle. E ne e le sebaka se habeli sa ho lahlela litšila tse ntšang mahlaseli a kotsi 'me hajoale e kotsing ea liphuputso tsa litšisinyeho tsa lefatše.

Ho fallela ka leboea ho re tlisa ho Baltimore Canyon, e tsotehang ka ho ba e 'ngoe ea libaka tse tharo feela tsa methane tse haufi le shelefo ea Mid-Atlantic. Methapo ea methane e theha tikoloho e ikhethang ea 'mele le ea lik'hemik'hale; tikoloho eo bo-mussels le makhala a lokeloang hantle ho yona. Baltimore e bohlokoa bakeng sa bophelo bo bongata ba likorale mme e sebetsa joalo ka libaka tsa tlhokomelo ea mefuta ea khoebo.

Likhohlopo tsena tse tebileng tsa leoatle, joalo ka Wilmington 'me Spencer Lithakha, ke libaka tse behang litholoana tsa ho tšoasa litlhapi. Mefuta-futa ea mefuta-futa le bongata bo phahameng ba mefuta ea liphoofolo li etsa sebaka se loketseng bakeng sa batšoasi ba litlhapi ba ithabisang le ba khoebo. Ntho e 'ngoe le e 'ngoe ho tloha ho makhala ho ea ho tuna le lishaka li ka tšoasoa mona. Ka ha e le sebaka sa bodulo sa bohlokwa bakeng sa mefuta e mengata ya dihlapi, ho sireletsa diphula nakong ya dihlahiswa tsa ho tswala ho ka thusa haholo taolong ya botshwasi.  Tom's Canyon Complex - letoto la likhohlo tse 'maloa tse nyane - e boetse e khethetsoe libaka tsa eona tse makatsang tsa ho tšoasa litlhapi.

Kaha ke matsatsi a seng makae feela ka mor'a Halloween, sena e ke ke ea e-ba poso e ngata ntle le ho bua ka ntho e monate - bubblegum! Coral, ke hore. Mefuta ena e bitsoang evocatively e fumanoe ke lipatlisiso tsa leoatle tse tebileng tsa NOAA ho Veatch 'me Gilbert Lithakha. Gilbert ha aa ka a khetheloa ho ba le mefuta e mengata ea likorale; empa leeto la NOAA haufinyane le fumane se fapaneng le 'nete. Re ntse re ithuta ka linako tsohle hore na ho na le mefuta e mengata hakae e ka fumanoang ho seo re nkang hore ke maqhubu a sa pheleng a botebo ba leoatle. Empa bohle re tseba se etsahalang ha re nahana!

Ho latela tsela ena ea likhohlo ke eona e kholo ka ho fetisisa ho tsona kaofela - the Hudson Canyon. E boima ba lik'hilomithara tse 740 le botebo ba limithara tse 3200, e tebile habeli ho feta Grand Canyon e tsotehang le sebaka sa bolulo sa liphoofolo le limela - ho tloha ho libōpuoa tse phelang botebong ho ea ho maruarua a charismatic le li-dolphin tse tsamaeang haufi le holimo. Joalo ka ha lebitso la eona le bolela, ke katoloso ea Sisteme ea Hudson River - e senola maoatle a hokahaneng le naha. Ba e tsebang ba tla nahana ka libaka tse ngata tsa ho tšoasa litlhapi tsa tuna le li-bass tsa leoatleng le letšo. Na ba boetse ba tseba hore Facebook, imeile, le BuzzFeed kaofela li tsoa Hudson Canyon? Sebaka sena se ka tlas'a leoatle ke khubu ea likhoele tsa puisano tsa fiber-optic tse re hokahanyang lefatšeng ka bophara. Seo re khutlelang ho sona se tlase ho feta linaleli - tšilafalo le lithōle li tsamaisoa ho tsoa mehloling e holim'a naha 'me li lula ka har'a likhohlo tse tebileng haufi le mefuta ea tsona ea mefuta-futa.

Ocean Foundation e keteka selemo sa rona sa boshome New York City bekeng ena - seo hape re ts'epileng ho se keteka haufinyane ke ts'ireletso ea likhohlo tse tsamaeang ka tlas'a metsi. Ho tšehetsa lihlopha tsa litlhapi, libaka tsa bohlokoa tsa bana, liphoofolo tsa leoatleng tse kholo le tse nyenyane, le bongata ba libōpuoa tse nang le li-benthic, li-canyon tsena ke khopotso e tsotehang ea mefuta-futa ea bophelo metsing a rona. Liemahale tse holimo tse holimo literateng tsa New York li etsisa likhohlo tse khōlōhali tse botlaaseng ba leoatle. Lerata la bophelo literateng tsa New York - mabone, batho, li-tickers tsa litaba, mehala le matlapa a hokahaneng marang-rang - le tsona li etsisa bophelo bo bongata bo ka tlas'a leoatle 'me li re hopotsa hore na li bohlokoa hakae bophelong ba rona ba letsatsi le letsatsi lefatšeng.

Joale Grand Canyon le New York City li tšoana ka eng? Ke likhopotso tse bonahalang haholoanyane tsa limakatso tsa tlhaho le tse entsoeng ke batho tse ka tlas’a maqhubu.
