NaCaroline Coogan, Research Intern, The Ocean Foundation

Pese pandinofamba kuenda kuNew York ndinorohwa nehana - uye kazhinji ndinoremerwa - nezvivakwa zvihombe uye nehupenyu hwakabatikana. Rakamira pasi pechivakwa chakareba 300 m kana kutarisa pamusoro penzvimbo yaro yekutarisa, guta rinogona kunge riri sango remudhorobha rinouya pamusoro kana dhorobha rematoyi rinopenya pazasi. Fungidzira uchisvetuka kubva kumusoro kweNew York City kusvika pakadzika peGrand Canyon, 1800 m pasi.

Hukuru hweaya mashura akaitwa nevanhu uye emusikirwo akakurudzira vanyori vemifananidzo, nyanzvi dzezvakasikwa, uye masayendisiti kwemazana emakore. A ichangobva kuratidzwa by Gus Petro fungidzira guta riri pakati pemipata nepamusoro peGrand Canyon - asi ko kana ndikakuudza kuti kune canyon yakapetwa kaviri kukura kwayo muNew York? Hapana kudiwa kwe photoshop pano, iyo Hudson Canyon yakareba 740 km uye 3200 m kudzika uye mamaira chete kudzika kweRwizi Hudson uye pasi pegungwa rakadzika rebhuruu…

Iyo Mid-Atlantic sherufu yakashongedzerwa nemacanyon uye seamounts, imwe neimwe inoyevedza seGrand Canyon uye kungobatikana seNew York City. Mavara ane simba uye akasarudzika marudzi anotenderera pasi kana rwendo nepakati pakadzika. Kubva kuVirginia kuenda kuNew York City kune gumi anozivikanwa makoronga egungwa akadzika akazara nehupenyu - gumi makoronga anotitungamira kune imwe yemhemberero dzedu dzemakore gumi.

Makoni kubva kuVirginia neWashington, DC - iyo Norfolk, Washington, uye Accomac canyons - vane mimwe mienzaniso yekumaodzanyemba yemakorari emvura inotonhora uye mhuka dzayo dzakabatana. Makorari anowanzo kusanganiswa nemvura inodziya, inopisa. Makorari emvura yakadzika akakosha uye anotambira zvakangosiyana zvakasiyana-siyana sezvipenyu sehama dzavo dzemahombekombe. The Norfolk Canyon yakakurudzirwa senzvimbo yakachengetedzwa yemugungwa nguva nenguva, muenzaniso chaiwo wenzira yatinobata nayo pfuma yedu yekunze. Yakanga iri nzvimbo yakapetwa kaviri yekurasira tsvina yeradioactive uye parizvino iri kutyisidzirwa neongororo yekudengenyeka kwenyika.

Kuenda kuchamhembe kunotisvitsa Baltimore Canyon, inoshamisa nekuve imwe yematatu chete emethane anofamba pamwe neMid-Atlantic sherufu. Methane seeps inogadzira yakasarudzika chaiyo yemuviri nemakemikari nharaunda; nharaunda iyo dzimwe mussels nemagakanje zvinonyatsoenderana. Baltimore yakakosha nekuda kwekuwanda kwayo kwehupenyu hwekorari uye kushanda senzvimbo dzekuchengetera mhuka dzekutengesa.

Aya makadzika egungwa makoni, akadai Wilmington uye Spencer canyons, inzvimbo dzokuredza dzinobereka zvibereko. Kusiyana-siyana uye kuwanda kwezvipenyu zvinogadzira nzvimbo yakanaka yevaraidzo nevekutengesa hove. Zvese kubva kumakanje kusvika kune tuna uye shark zvinogona kubatwa pano. Sezvo ari ugaro hwakakosha hwezvipenyu zvakawanda, kuchengetedza makombi mukati memwaka wekubereka kunogona kuita zvakawanda zvakanaka pakubata hove.  Tom's Canyon Complex - nhevedzano yemakoni madiki akati wandei - inosarudzwawo kune yayo inoshamisa nzvimbo dzekuredza.

Sezvo angori mazuva mashoma mushure meHalloween, izvi hazvingave zvakawanda zvekutumira pasina kutaura chimwe chinhu chinotapira - bubblegum! Coral, ndizvo. Iyi mhuka ine mazita evocative yakawanikwa neNOAA yakadzika gungwa kuongorora mukati Veatch uye Gilbert canyons. Gilbert haana kutanga asarudzwa kuti ave nemhando dzakasiyana-siyana dzemakorari; asi NOAA expedition ichangobva kuona zvakapesana ichokwadi. Isu tiri kudzidza nguva dzese kuti kwakasiyana kwakadii kunowanikwa mune zvatinofungidzira kuti mafungu asina hupenyu epasi pegungwa. Asi isu tese tinoziva zvinoitika kana tikafungidzira!

Kutevera iyi nzira yemakoni ndiyo yakakura kupfuura dzese - iyo Hudson Canyon. Inoyera mukati memakiromita 740 kureba uye 3200 metres kudzika, yakadzika zvakapetwa kaviri seGrand Canyon inotyisa uye nzvimbo yezvipfuyo nemaruva - kubva kune zvisikwa zvebenthic mukadzika kusvika kune charismatic whales nema dolphin anofamba pedyo nepamusoro pedenga. Sezvinoreva zita rayo, ndeyekuwedzeredzwa kweHudson River system - kuburitsa makungwa akananga kubatana nenyika. Vanozviziva vachafunga nezvenzvimbo dzekuredza dzakawanda dzetuna nemabass egungwa dema. Vanozivawo here kuti Facebook, email, uye BuzzFeed zvese zvinobva kuHudson Canyon? Iyi nharaunda yepasi pegungwa ndiyo musimboti wetambo dzefiber-optic telecommunication dzinotibatanidza nenyika yakakura. Zvatinodzokera kwazviri ishoma pane stellar - kusvibiswa nemarara zvinofambiswa kubva kune zvitubu zviri panyika uye zvinogara mumakoni akadzika aya padivi pemhando dzakasiyana dzezvipenyu.

Sangano reOcean Foundation riri kupemberera kusvitsa kwedu makore gumi muNew York City svondo rino - chatiri kutarisirawo kupemberera munguva pfupi iri kutevera kuchengetedzwa kwemakombi epasi pemvura. Kutsigira kubereka kwehove, nzvimbo dzakakosha dzekurera vana, mhuka dzemugungwa huru nezvidiki, uye zvisikwa zvakawanda zvebenthic, makoni aya chiyeuchidzo chinoshamisa chekusiyana kwehupenyu mukati memvura yedu. Zvivakwa zvedenga zvinouya pamusoro pemigwagwa yeNew York zvinotevedzera mahombe akakura ari pasi pegungwa. Mhirizhonga yehupenyu mumigwagwa yeNew York - marambi, vanhu, zviteki zvenhau, nharembozha uye mahwendefa zvakabatanidzwa neinternet - zvakare inotevedzera hupenyu hwakazara pasi pegungwa uye inotiyeuchidza kukosha kwazvakaita kuhupenyu hwedu hwezuva nezuva panyika.

Saka Grand Canyon neNew York City dzakafanana papi? Ndivo zvimwe-zviyeuchidzo zvinooneka zvechisikigo uye zvishamiso zvakaitwa nevanhu zviri pasi pemasaisai.
