Wolemba Caroline Coogan, Research Intern, The Ocean Foundation

Nthawi zonse ndikapita ku New York ndimakhudzidwa - ndipo nthawi zambiri ndimadabwitsidwa - ndi nyumba zazitali komanso moyo wodzaza. Kuyimirira pansi pa nyumba yayitali 300 m kapena kuyang'ana pamalo ake owonera, mzindawu ukhoza kukhala nkhalango yamtawuni yomwe ikubwera pamwamba kapena mzinda wonyezimira wonyezimira wowala pansi. Tangoganizani kudumpha kuchokera pamwamba pa New York City kupita kukuya kwa Grand Canyon, 1800 m pansi.

Kuchuluka kwa zozizwitsa zopangidwa ndi anthu ndi zachilengedwe kwalimbikitsa akatswiri ojambula, akatswiri a zachilengedwe, ndi asayansi kwa zaka mazana ambiri. Chiwonetsero chaposachedwa ndi Ndi Petro Kodi mukuganiza kuti mzindawu uli pakati pa zigwa ndi nsonga za Grand Canyon - koma bwanji ndikakuuzani kuti kuli canyon kuwirikiza kawiri kukula kwake ku New York? Palibe chifukwa cha photoshop pano, ndi Hudson Canyon ndi 740 km kutalika ndi 3200 m kuya ndi mailosi chabe kutsika kwa Hudson River ndi pansi pa nyanja yakuya yabuluu ...

Shelefu ya ku Mid-Atlantic ili ndi ma canyons ndi ma seamounts, chilichonse chowoneka bwino ngati Grand Canyon komanso pikitipikiti ngati New York City. Mitundu yowoneka bwino ndi mitundu yapadera imatsata pansi kapena kuyenda mozama. Kuchokera ku Virginia kupita ku New York City pali zigwa khumi zodziwika bwino za m'nyanja zodzaza ndi moyo - ma canyons khumi akutitsogolera ku chikondwerero china chazaka 10.

Ma canyons ochokera ku Virginia ndi Washington, DC - the Norfolk, Washington, ndi Accomac Makanta - khalani ndi zitsanzo zakum'mwera za corals zamadzi ozizira ndi nyama zomwe zimagwirizana nazo. Makorali nthawi zambiri amagwirizanitsidwa ndi madzi otentha, otentha. Ma corals amadzi akuya ndi ofunika kwambiri ndipo amakhala ndi mitundu yosiyanasiyana ya zamoyo monga momwe amachitira azisuweni awo. The Norfolk Canyon wakhala akulimbikitsidwa ngati malo otetezedwa a panyanja mobwerezabwereza, chitsanzo cha momwe timachitira chuma chathu chakunyanja. Anali kawiri ngati malo otayirapo zinyalala zotulutsa ma radio ndipo pakali pano ali pachiopsezo ndi kafukufuku wokhudza zivomezi.

Kusamukira kumpoto kumatifikitsa ku Baltimore Canyon, chodabwitsa chifukwa chokhala m'modzi mwa ma methane atatu okha omwe amadutsa pa shelufu ya Mid-Atlantic. Mitsinje ya methane imapanga malo apadera owoneka bwino ndi makemikolo; malo omwe nkhono zina ndi nkhanu ndizoyenera. Baltimore ndiyofunikira chifukwa cha kuchuluka kwa moyo wa ma coral ndipo imagwira ntchito ngati malo osungiramo mitundu yamalonda.

Izi ngalande zakuya za m'nyanja, monga Wilmington ndi Spencer Makanta, ndi malo opherako zinthu zambiri. Kusiyanasiyana ndi kuchuluka kwa zamoyo zamtunduwu kumapangitsa malo abwino oti asodzi asangalale ndi malonda. Chilichonse kuyambira nkhanu mpaka tuna ndi shaki zitha kupha nsomba pano. Popeza ndi malo ofunika kwambiri kwa zamoyo zambiri, kuteteza zigwa panthawi yoswana kungathandize kwambiri pakuwongolera nsomba.  Tom's Canyon Complex - angapo ang'onoang'ono canyons - nawonso amasankhidwa chifukwa cha malo ake osodza ochititsa chidwi.

Popeza kwangodutsa masiku ochepa pambuyo pa Halowini, izi sizingakhale zolemba zambiri popanda kutchula chinthu chokoma - bubblegum! Coral, ndiye. Mitundu yotchedwa evocatively iyi yapezeka ndi kufufuza kwa nyanja ya NOAA Veatch ndi Gilbert Makanta. Gilbert sanasankhidwe poyamba chifukwa chokhala ndi mitundu yambiri ya ma coral; koma ulendo wa NOAA posachedwapa wapeza kuti zosiyana zinali zoona. Tikuphunzira nthawi zonse kuchuluka kwa kusiyanasiyana komwe kumapezeka muzomwe timaganiza kuti ndi mafunde opanda moyo pansi panyanja. Koma tonse tikudziwa zomwe zimachitika tikaganiza!

Kutsatira njira iyi ya canyons ndiye wamkulu kuposa onse - the Hudson Canyon. Kulemera kwa makilomita 740 m'litali ndi mamita 3200 kuya, ndi kuya kuwirikiza kawiri kuposa Grand Canyon yochititsa mantha komanso malo osungira nyama ndi zomera - kuchokera ku zolengedwa zamtundu wakuya mpaka ku anamgumi ochititsa chidwi ndi ma dolphin omwe akuyenda pafupi ndi pamwamba. Monga dzina lake limatanthawuzira, ndikuwonjeza kwa mtsinje wa Hudson - kuwulula nyanja zomwe zimalumikizana ndi nthaka. Amene akuchidziwa amalingalira za malo ambiri ophera nsomba za tuna ndi nsomba za m’nyanja zakuda. Kodi amadziwanso kuti Facebook, imelo, ndi BuzzFeed zonse zimachokera ku Hudson Canyon? Dera la pansi pa nyanja iyi ndi phata la zingwe za telecommunication za fiber optic zomwe zimatilumikiza padziko lonse lapansi. Zomwe timabwererako ndizochepa kwambiri kuposa nyenyezi - kuipitsidwa ndi zinyalala zimatengedwa kuchokera kumtunda ndikukhazikika m'malo ozama awa pafupi ndi mitundu yosiyanasiyana ya zamoyo.

Ocean Foundation ikukondwerera chaka chathu chakhumi ku New York City sabata ino - zomwe tikuyembekezeranso kuti tizikondwerera posachedwa ndi chitetezo cha ma canyons apamadzi. Kuthandizira kuswana kwa nsomba, malo odyetserako ana ofunikira, nyama zam'madzi zazikulu ndi zazing'ono, komanso zamoyo zambiri zokhala ndi benthic, ma canyons ndi chikumbutso chodabwitsa cha mitundu yosiyanasiyana ya zamoyo m'madzi athu. Nyumba zosanjikizana zomwe zili pamwamba pa misewu ya ku New York zimatsanzira zigwa zazikulu zomwe zili pansi pa nyanja. Phokoso la moyo m'misewu ya New York - magetsi, anthu, zokopera nkhani, mafoni ndi mapiritsi olumikizidwa pa intaneti - amatsanziranso moyo wochuluka pansi pa nyanja ndipo amatikumbutsa kufunika kwa moyo wathu watsiku ndi tsiku pamtunda.

Ndiye kodi Grand Canyon ndi New York City zikufanana chiyani? Ndizo zikumbutso zowoneka bwino za zodabwitsa zachilengedwe ndi zopangidwa ndi anthu zomwe zili pansi pa mafunde.
