Mar labaad, balaastiiggu waxay caddeeyeen inay meel walba ku yaalliin badda dhexdeeda.Ku quusidda gunta hoose ee Mariana Trench, oo lagu eedeeyay in ay gaartay 35,849 cagood, ganacsade Dallas Victor Vescovo ayaa sheegay in uu helay bac.Tani xitaa maaha markii ugu horeysay: tani waa markii saddexaad ee balaastiga laga helo qaybta hoose ee badda.
Vescovo waxa uu ku quusay meel lagu maydho 28-kii Abriil iyada oo qayb ka ah socdaalkiisii “Shan Moolood”, oo ay ku jirto safar uu ku tagayo meelaha ugu hooseeya ee badaha dhulka.Intii lagu guda jiray afartii saacadood ee Vescovo ee gunta hoose ee Trench Mariana, wuxuu arkay dhowr nooc oo nolosha badda ah, kuwaas oo mid ka mid ah uu noqon karo nooc cusub - bac iyo nacnac nacnac ah.
In yar ayaa gaadhay mool aad u daran.Injineer Swiss ah Jacques Piccard iyo Don Walsh waxay ahaayeen kuwii ugu horreeyay ee 1960. Sahamiyaha National Geographic iyo filimsameeye James Cameron ayaa ku degay gunta hoose ee badda 2012. Cameron wuxuu duubay quus ilaa 35,787 cagood, wax yar oo ka yar 62 cagood. Vescovo ayaa sheegtay inay gaartay.
Si ka duwan bini'aadamka, balaastiiggu si sahal ah ayay u dhacdaa.Horraantii sanadkan, daraasad ayaa tijaabisay amphipods oo laga soo qaaday lix god oo qoto dheer oo badda ah, oo ay ku jiraan Marianas, waxaana lagu ogaaday in dhammaantood ay la qabsadeen microplastics.
Daraasad la daabacay Oktoobar 2018 ayaa diiwaangelisay caagga ugu qoto dheer ee loo yaqaan - bac dukaameysi jilicsan - oo laga helay 36,000 oo cagood qoto dheer gudaha Mariana Trench.Saynis yahanadu waxa ay daah-fureen iyaga oo baadhay xogta kaydka qashinka badda ee Deep Sea, kaas oo ka kooban sawiro iyo muuqaalo 5,010 quusitaan ah 30kii sano ee la soo dhaafay.
Qashinka la kala soocay ee lagu diiwaan geliyey keydka xogta, balaastikada ayaa ah tan ugu badan, gaar ahaan bacaha ayaa ah isha ugu weyn ee qashinka caagga ah.Qashinka kale wuxuu ka yimid agabka sida caag, bir, alwaax iyo dhar.
Ilaa 89% caagadaha lagu sameeyay daraasadda ayaa ahaa kuwo hal mar la isticmaalo, kuwa hal mar la isticmaalo ka dibna la tuuro, sida caagagga biyaha laga sameeyo ama alaabta miiska la tuuro.
Marina Trench ma aha god mugdi ah oo aan nolol lahayn, waxay leedahay dad badan oo deggan.NOAA Okeanos Explorer ayaa sahamisay gunta hoose ee gobolka 2016 waxayna heshay noocyo kala duwan oo nolosha ah, oo ay ku jiraan noocyada sida shacaab, jellyfish iyo octopuss.Daraasadda 2018 waxay sidoo kale ogaatay in 17 boqolkiiba sawirada caagga ah ee lagu duubay xogta ay muujiyeen nooc ka mid ah isdhexgalka nolosha badda, sida xayawaanka oo ku dhex milmay qashinka.
Balaastii keligiis la isticmaalo waa meel walba waxayna qaadan kartaa boqolaal sano ama ka badan inay ku qudhunto duurka.Marka loo eego daraasad bishii Febraayo 2017, heerarka wasakhda ee marinka Mariana Trench ayaa ka sarreeya meelaha qaar marka loo eego qaar ka mid ah webiyada ugu wasakhaysan Shiinaha.Qorayaasha daraasadda waxay soo jeedinayaan in wasakhowga kiimikaad ee godadku ay ka iman karaan qayb ka mid ah caagagga tiirka biyaha.
Gooryaanka Tubeworm (casaan), eel iyo carsaanyo jockey waxay helayaan meel u dhow hawo-mareenka kuleylka.(Baro wax ku saabsan xayawaannada qariibka ah ee hawo-mareennada kuleylka hooseeya ee Pacific-ga.)
Iyadoo bacaha ay si toos ah u soo geli karaan badda, sida qashinka laga soo tuuray xeebaha ama laga soo daadiyo doomaha, ayaa cilmi-baaris la daabacay sannadkii 2017-kii lagu ogaaday in intooda badan ay badda ka galaan 10-wabi oo dhex mara deegaannada ay dadku deggen yihiin.
Qalabka kalluumeysiga ee la dayacay ayaa sidoo kale ah isha ugu weyn ee wasakhowga caagga ah, iyada oo daraasad la daabacay bishii Maarso 2018 taas oo muujinaysa in maaddadu ay ka kooban tahay inta badan Texas Qashinka Qashinka Baasifigga ee Weyn ee u dhexeeya Hawaii iyo California.
Iyadoo ay caddahay in bacaha badda ku jira ay aad uga badan yihiin kuwa ku jira hal bac, haddana shaygu waxa uu ka soo baxay sarbeeb aan dan lahayn oo dabaysha ah oo tusaale u ah inta ay bani'aadamku saameeyaan meeraha.
