Los ntawm Caroline Coogan, Kev Tshawb Fawb Kev Tshawb Fawb, Ocean Foundation

Txhua zaus kuv mus rau New York kuv raug ntaus - thiab feem ntau ntxhov siab - los ntawm cov vaj tse uas muaj zog heev thiab lub neej bustling. Sawv hauv qab ib lub tsev siab 300 m los yog saib nws lub lawj saib, lub nroog tuaj yeem yog lub nroog hav zoov looming saum taub hau lossis lub nroog cov khoom ua si twinkling ci ntsa iab hauv qab no. Xav txog kev dhia ntawm qhov siab ntawm New York City mus rau qhov tob ntawm Grand Canyon, 1800 m nqes.

Qhov loj ntawm cov txiv neej tsim thiab ntuj tsim tau tshoov siab rau cov kws kos duab, naturalists, thiab cov kws tshawb fawb rau ntau pua xyoo. Ib qho kev nthuav qhia tsis ntev los no los ntawm Gus Petro xav txog lub nroog nyob hauv nruab nrab ntawm cov hav thiab lub ncov ntawm Grand Canyon - tab sis yuav ua li cas yog tias kuv hais rau koj tias muaj ib lub hav txwv yeem ob zaug nws loj nyob hauv New York? Tsis xav tau photoshop ntawm no, lub Hudson Canyon yog 740 km ntev thiab 3200 m tob thiab mere mais ntawm Hudson River thiab hauv qab dej hiav txwv xiav tob…

Lub Mid-Atlantic txee yog pock-kos npe nrog canyons thiab seamounts, txhua yam zoo li tus Grand Canyon thiab tsuas yog bustling li New York City. Vibrant xim thiab cim hom kab hauv pem teb los yog caij nkoj los ntawm qhov tob. Los ntawm Virginia mus rau New York City muaj kaum qhov tseem ceeb ntawm lub hiav txwv tob tob uas muaj lub neej - kaum lub hav txwv yeem coj peb mus rau lwm qhov ntawm peb qhov kev ua koob tsheej 10 xyoo.

Cov canyons tawm ntawm Virginia thiab Washington, DC - lub NWS Norfolk, Washington, thiab Accomac Hav cuam kawb - muaj qee qhov piv txwv yav qab teb ntawm cov dej txias corals thiab lawv cov tsiaj sib txuas. Corals feem ntau yog txuam nrog cov dej sov, dej kub. Cov dej sib sib zog nqus yog ib qho tseem ceeb thiab muaj ntau hom kev sib txawv raws li lawv cov kwv tij txheeb ze. Cov Norfolk hav cuam kawb tau raug pom zoo raws li kev tiv thaiv marine sanctuary lub sij hawm thiab dua, ib qho piv txwv ntawm txoj kev uas peb kho peb offshore treasures. Nws yog ob zaug hauv av pov tseg rau cov khoom siv hluav taws xob pov tseg thiab tam sim no raug kev hem thawj los ntawm kev tshawb fawb seismic.

Kev txav mus rau sab qaum teb coj peb mus rau qhov Baltimore Canyon, zoo kawg li uas yog ib qho ntawm peb lub methane seeps raws Mid-Atlantic txee. Methane seeps tsim ib qho chaw tshwj xeeb ntawm lub cev thiab tshuaj lom neeg; ib puag ncig uas qee cov mussels thiab crabs zoo haum. Baltimore yog qhov tseem ceeb rau nws txoj kev nplua nuj ntawm coral lub neej thiab ua haujlwm ua chaw zov me nyuam rau hom kev lag luam.

Cov dej hiav txwv tob no, xws li Wilmington thiab Spencer Hav cuam kawb, yog thaj chaw nuv ntses tsim khoom. Kev sib txawv thiab ntau hom tsiaj tsim ib qho chaw zoo tagnrho rau kev ua si thiab kev lag luam nuv ntses. Txhua yam ntawm crabs mus rau tuna thiab sharks tuaj yeem nuv ntses ntawm no. Raws li lawv yog qhov chaw nyob tseem ceeb rau ntau hom, kev tiv thaiv canyons thaum lub caij spawning yuav ua tau zoo heev rau kev tswj nuv ntses.  Tom's Canyon Complex - ib tug series ntawm ob peb me me canyons - tseem hu ua ib tug zoo kawg nkaus nuv ntses qhov chaw.

Raws li nws tsuas yog ob peb hnub tom qab Halloween, qhov no yuav tsis yog ntau ntawm kev tshaj tawm yam tsis tau hais txog qee yam qab zib - bubblegum! Coral, uas yog. Lub npe hu ua evocatively no tau pom los ntawm NOAA qhov kev tshawb nrhiav hauv hiav txwv tob hauv Veatch thiab Gilbert Hav cuam kawb. Gilbert tsis yog Ameslikas hu ua rau muaj ntau haiv neeg ntawm corals; tab sis NOAA ntoj ke mus kawm tsis ntev los no tau pom qhov kev tawm tsam yog qhov tseeb. Peb tab tom kawm txhua lub sij hawm ntau npaum li cas muaj ntau haiv neeg yuav pom nyob rau hauv qhov peb xav tias yog lifeless swaths ntawm lub hiav txwv pem teb. Tab sis peb txhua tus paub tias yuav ua li cas thaum peb xav!

Ua raws li txoj kev no ntawm cov hav txwv yeem yog qhov loj tshaj plaws ntawm lawv txhua tus - lub Hudson hav cuam kawb. Qhov hnyav ntawm 740 mais ntev thiab 3200 meters tob, nws yog ob zaug tob li qhov txaus ntshai ntawm Grand Canyon thiab ib qho chaw rau fauna thiab flora - los ntawm cov tsiaj nyob hauv qhov tob mus rau charismatic whales thiab ntses taub ntses nyob ze rau saum npoo. Raws li nws lub npe qhia, nws yog qhov txuas ntxiv ntawm Hudson River system - nthuav tawm cov dej hiav txwv ncaj qha mus rau thaj av. Cov neeg uas paub nws yuav xav txog ntau qhov chaw nuv ntses rau tuna thiab ntses bass thaj tsam dub. Lawv puas paub tias Facebook, email, thiab BuzzFeed txhua tus tuaj ntawm Hudson Canyon? Lub cheeb tsam hauv qab no yog lub hauv paus ntawm fiber ntau-optic telecommunication cables uas ntsaws peb rau hauv lub ntiaj teb dav. Qhov peb rov qab los rau nws yog tsawg dua li cov hnub qub - cov pa phem thiab cov thoob khib nyiab tau xa tawm los ntawm cov chaw hauv av thiab nyob rau hauv cov hav dej tob no nrog rau lawv ntau hom tsiaj.

Lub Koom Haum Dej Hiav Txwv tau ua kev zoo siab rau peb lub xyoo kaum hauv New York City lub lim tiam no - qhov peb tseem cia siab tias yuav ua kev zoo siab sai sai no yog kev tiv thaiv submarine canyons. Txhawb nqa spawning aggregations ntawm ntses, chaw zov me nyuam tseem ceeb, marine mammals loj thiab me, thiab ib tug tswv tsev ntawm benthic creatures, cov canyons yog ib tug stunning ceeb toom ntawm ntau haiv neeg ntawm lub neej nyob rau hauv peb cov dej. skyscrapers looming saum txoj kev ntawm New York ua raws li cov hav dej loj loj hauv dej hiav txwv. Lub suab nrov ntawm lub neej ntawm New York txoj kev - lub teeb, tib neeg, cov xov xwm tickers, xov tooj thiab ntsiav tshuaj txuas nrog hauv internet - kuj ua rau lub neej muaj txiaj ntsig hauv qab hiav txwv thiab qhia peb tias lawv tseem ceeb npaum li cas rau peb lub neej niaj hnub hauv av.

Yog li dab tsi Grand Canyon thiab New York City muaj qhov sib xws? Lawv yog cov cim qhia pom ntau dua ntawm lub ntuj thiab tib neeg tsim kev xav uas nyob hauv qab nthwv dej.
