He aha ka Hadal Zone ma ka Geology Moana?
Pendahuluan
He honua piha ko kākou Honua i nā mea kupanaha a me nā mea pohihihi. ʻO kekahi o nā wahi hoihoi a paʻakikī loa e ʻimi ai, ʻo ia ke kai hohonu. Ua hoʻopio ke kai i nā kānaka ʻepekema me kona ʻano kū hoʻokahi a me nā mea pohihihi. I loko o kēia moana nui, aia nā ʻāpana like ʻole e like me ko lākou hohonu a me nā kūlana o ke kaiapuni, ʻo kekahi o nā mea koʻikoʻi loa ʻo ia ka ʻāpana hadal. E ʻimi hohonu kēia ʻatikala i ke ʻano o ka ʻāpana hadal i ka geology moana, kona mau ʻano, nā ʻano ola, a me nā pilikia noiʻi.
Ka Wehewehena o ka ʻĀpana Hadal
ʻO ka ʻāpana hadal, i kapa pinepine ʻia ʻo ka ʻāpana hadalpelagic, e pili ana i ka ʻāpana hohonu loa o nā moana o ka Honua, e hoʻolōʻihi ana mai ka hohonu o 6.000 mika (ma kahi o 19.685 kapuaʻi) a hiki i ka lalo o nā ʻauwaha moana. Ua loaʻa ka inoa "hadal" mai Hades mai, ke akua o ka honua lalo i ka moʻolelo Helene, e hōʻike ana i nā kūlana pouli, kokoke i ka ʻole o ka lā o ka hohonu.
Aia i loko o kēia ʻāpana nā ʻauwaha moana hohonu loa, e like me ka Mariana Trench ma ka Moana Pākīpika, ʻo ia ka wahi hohonu loa ma ka ʻili o ka Honua, e hōʻea ana i ka hohonu ma mua o 11.000 mika. ʻOiai he wahi liʻiliʻi kona e noho ana i ka hoʻohālikelike ʻia me nā moana o ka honua, he kuleana koʻikoʻi nō naʻe ka ʻāpana hadal i loko o ka ʻōnaehana kai honua.
Nā ʻano o ka ʻĀpana Hadal
He nui nā ʻano kūikawā o ka ʻāpana hadal e hoʻokaʻawale iā ia mai nā ʻāpana moana ʻē aʻe:
1. Ka hohonu a me ke kaomi
Hoʻomaka ka ʻāpana hadal ma kahi hohonu o 6.000 mika a hiki ke piʻi ma luna o 11.000 mika ma kekahi mau ʻauwaha moana. Ma kēia mau hohonu, kiʻekiʻe loa ke kaomi wai, e hiki ana ma luna o 1.100 mau lewa (ʻo ke kaomi lewa ma ka ʻilikai ma kahi o 1 lewa). ʻO kēia kaomi nui e hoʻolilo i ka noho ʻana ma ka ʻāpana hadal i mea paʻakikī nui no nā meaola ola a me nā lako noiʻi.
2. Mahana
He haʻahaʻa loa nā mahana ma ka ʻāpana hadal, maʻamau mai 1 a 4 degere Celsius. Hōʻike kēia i kahi pilikia hou aʻe no nā mea ola e pono e ola i kahi kaiapuni anu mau.
3. Mālamalama
I loko o ka hohonu o ka ʻāpana hadal, ʻaʻole hiki i ka lā ke komo i loko. He pōʻeleʻele loa kēia ʻāpana, e hilinaʻi wale ana i ka bioluminescence mai kekahi mau mea ola.
4. ʻAi Meaʻai
He palena loa ka lako o nā meaʻai ma ka ʻāpana hadal, ʻo ka hapa nui e hele mai ana mai nā detritus (nā ʻāpana organik make) e hāʻule ana mai luna mai (ka hau kai) a kākoʻo i ka ʻōnaehana ola honua o ka papakū kai.
Ke ola ma ka ʻāpana ʻo Hadal
ʻOiai ke kūlana koʻikoʻi o ke kaiapuni ma ka ʻāpana hadal, ua hoʻololi a ola kekahi mau meaola kūikawā ma laila. Eia kekahi mau laʻana o ke ola ma ka ʻāpana hadal:
1. Nā meaola liʻiliʻi loa
Hiki i nā microorganisms extremophile, e like me ka bacteria a me ka archaea, ke ola i nā wahi koʻikoʻi ma o ka hoʻohana ʻana i nā pūhui kemika i loaʻa ma ka papahele o ke kai. Hoʻokumu pinepine lākou i ke kumu o ke kaulahao meaʻai ma ka ʻāpana hadal.
2. Nā Crustacea a me nā Isopods
Ua ʻike ʻia kekahi mau ʻano ʻōpae a me nā isopods ma ka ʻāpana hadal. Loaʻa iā lākou nā hoʻololi kino e like me nā kino pālahalaha a paʻakikī e kū i nā kaomi kiʻekiʻe a me ka hiki ke ola ma ka liʻiliʻi o ka meaʻai.
3. Iʻa Hadal
Loaʻa i nā iʻa e noho ana ma ka ʻāpana hadal nā hoʻololi kūikawā, e like me nā kino palupalu a me nā ʻano iwi palupalu, e kū ai i ke kaomi o waho. Hōʻike kekahi mau ʻano, e like me ka hadal snailfish, i ka ulu ʻana o ka hoʻololi kupaianaha.
4. Nā ilo Polychaete
Hiki i nā ʻano ilo like ʻole, me nā polychaetes, ke ola i kēia mau wahi koʻikoʻi. Loaʻa pinepine lākou a puni nā puka hydrothermal a me nā awāwa hadal i waiwai i nā hui sulfur.
Ke Koʻikoʻi o ka Noiʻi ʻana i ka Hadal Zone
He mea koʻikoʻi ka noiʻi ʻana ma ka ʻāpana hadal no ka hoʻomaopopo hou ʻana e pili ana i ko kākou mau moana a me ka neʻe ʻana o ka Honua. Eia kekahi mau kumu no ke koʻikoʻi o ka noiʻi ʻana ma ka ʻāpana hadal:
1. Ke Hoʻomaopopo ʻana i nā ʻŌnaehana Kai Hohonu
ʻO ke aʻo ʻana i nā kaiaolaola ʻāpana hadal e kōkua iā mākou e hoʻomaopopo pehea e hiki ai i ke ola ke ola i nā kūlana koʻikoʻi. Hāʻawi pū ia i ka ʻike i nā kumumanaʻo kumu o ka ecology a me nā hoʻololi ʻana o nā meaola ola.
2. Ka ʻIke ʻana i nā ʻAno Hou
Hōʻike pinepine kēlā me kēia misionari ʻimi i loko o ka ʻāpana hadal i nā ʻano hou i ʻike ʻole ʻia ma mua, e hoʻonui hou ana i ko mākou ʻike i ka taxonomy moana a me ka biology.
3. Nā Kaʻina Hana ʻĀina
He wahi koʻikoʻi ka ʻāpana hadal no ke aʻo ʻana i nā kaʻina hana geological e like me ka subduction tectonic plate a me ka hoʻokumu ʻana o nā ʻauwai moana. Kōkua kēia iā mākou e hoʻomaopopo i ka mōʻaukala a me nā dinamika o ka honua Honua.
4. Nā hopena o ka Biotechnology
He nui nā meaola e noho ana ma ka ʻāpana hadal i loaʻa nā hoʻololi biochemical kūikawā i loaʻa paha nā noi i ka biotechnology a me ka ʻoihana lāʻau lapaʻau, e like me nā enzymes i kū i ke kaomi kiʻekiʻe a me nā mahana haʻahaʻa.
Nā Pilikia Noiʻi ma ka Hadal Zone
ʻAʻole hana maʻalahi ka noiʻi ʻana ma ka ʻāpana hadal. ʻO kekahi o nā pilikia nui:
1. ʻEnehana a me nā Lako Hana
Pono nā lako hana kūikawā e hiki ke kū i nā kūlana koʻikoʻi no ke kaomi kiʻekiʻe ma ka ʻāpana hadal. ʻO ka hoʻomohala ʻana i nā ROV (Remotely Operated Vehicles) a me nā HOV (Human Operated Vehicles) hiki ke ola i nā hohonu ma mua o 11.000 mika he pilikia loea koʻikoʻi a pipiʻi hoʻi.
2. Logistics a me nā kumukūʻai
Pono nā huakaʻi i ka ʻāpana hadal i ka hoʻolālā akahele, nā kumuwaiwai nui, a me nā kumukūʻai kiʻekiʻe. ʻO ka logistics o ka hoʻokō ʻana i kēia mau misionari he mea keakea nui pinepine ia.
3. Nā Kūlana Kaiapuni
He mea weliweli nui nā kūlana ʻino o ke kaiapuni i nā lako a me ke kime noiʻi. ʻO nā hemahema loea a i ʻole ka hōʻino ʻia o nā lako he mau pilikia pinepine.
4. Nā Palena ʻIkepili
Ma muli o ka paʻakikī o ke komo ʻana, ua kaupalena loa ʻia ka ʻikepili ma ka ʻāpana hadal. Nui nā wahi i loko o ka ʻāpana hadal i koe i ka ʻimi ʻole ʻia a ʻaʻole i aʻo pono ʻia me nā kikoʻī.
Ka hopena
ʻO ka ʻāpana hadal kekahi o nā ʻāpana pohihihi a paʻakikī loa o ko kākou honua. Me kona kaomi koʻikoʻi, nā mahana haʻahaʻa, ka pouli loa, a me nā meaʻai palena ʻole, koi kēia ʻāpana i nā hoʻololi kūikawā mai nā ʻano ola e noho ana ma laila. Hāʻawi ka noiʻi ma ka ʻāpana hadal i ka hiki nui no nā ʻike ʻepekema hou, kahi ʻike maikaʻi aʻe o nā kaiaolaola kai hohonu, a me nā noi ma nā ʻano ʻoihana like ʻole.
ʻOiai nā pilikia he nui, wehe ka ʻimi ʻana i ka ʻāpana hadal i kahi puka makani i kahi honua i ʻike nui ʻole ʻia a hāʻawi nui i ko mākou ʻike i ke ola a me nā kaʻina hana geological ma ka Honua. Me nā holomua ʻenehana a me ka hoʻolaʻa ʻana o nā kānaka ʻepekema, hiki iā mākou ke manaʻolana e hoʻomau i ka wehe ʻana i nā mea huna o ka ʻāpana hadal a hoʻonui i ko mākou ʻike i ke kai hohonu a pohihihi.
