# Te Mārama ki te Akoranga Moana ā-Tūturu
Ko te onepūtaiao ā-tinana he peka o te onepūtaiao e pā ana ki te ako i ngā āhuatanga ā-tinana me ngā tukanga ā-tinana i roto i te moana. He whānuitia ngā kaupapa o tēnei mara, tae atu ki te tātari i ngā ia o te moana, ngā ngaru, ngā tai, me ā rātou taunekeneke ki te āhuarangi me te papa moana. He mea nui te mārama ki ēnei āhuatanga ā-tinana o te moana hei mārama ki ngā tauira āhuarangi whānui, ngā pūnaha rauropi moana, me te awe o ngā mahi a te tangata ki ngā taiao moana.
## Ngā Au o te Moana
Ko ngā ia moana he tauira rere nui o te wai moana e whakawhiti ana i te ao, e peia ana e te hau, te pāmahana, ngā pikinga tote, me te hurihanga o te Ao. Ka whakarōpūtia ngā ia ki ngā ia mata me ngā ia wai hohonu.
### Ngā Au o te Mata
Ko ngā ia o te mata o te moana, e puta ana i ngā mita 400 o runga o te moana, e peia ana e ngā tauira hau. Ko ngā hau hokohoko, ngā hau uru, me ngā hau rāwhiti o te pito o te moana ngā mana matua e pana ana i te wai mata huri noa i ngā takotoranga moana o te ao. Ko ngā gyre, arā, ngā pūnaha nui o ngā ia o te moana porowhita i hangaia e ngā tauira hau o te ao me ngā mana i hangaia e te hurihanga o te Ao, he āhuatanga nui i roto i ia takotoranga moana. Ko ētahi tauira rongonui ko te Gulf Stream i te Raki o te Moana Ataratiki, te Kuroshio Current i te Raki o te Moana-nui-a-Kiwa, me te Antarctic Circumpolar Current e huri ana i te whenua o Antarctica.
### Ngā Au o te Wai Hōhonu
Ko ngā ia wai hohonu, e mōhiotia ana ko te tohanga thermohaline, e peia ana e ngā rerekētanga o te mātotoru o te wai, e pāngia ana e te pāmahana me te tote. E whakaatu ana te ariā o te Global Conveyor Belt i tēnei tukanga: ka whakamatao te wai mata, ka piki ake te matotoru tata ki ngā pou, ka totohu hei akiaki i ngā ia moana hohonu e haere ana i te ao. He mahi nui tā tēnei tohanga i roto i te tohatoha wera, te huringa matūkai, me te kohikohinga o te hauhā waro i roto i te moana.
## Ngā Ngaru me ngā Tai
He mea nui ngā ngaru me ngā tai o ngā āhuatanga o te ao moana, e pā ana ki ngā taiao takutai, ki te whakatere moana, me ngā whanaketanga o te rauropi.
### Ngā Ngaru o te Moana
Ko ngā ngaru moana he wiri o te mata o te moana i puta mai i te hau, i ngā kaha ā-papa, me ngā mahi rū whenua. Ko ngā ngaru e puta mai ana i te hau te nuinga o te mata o te moana, ā, ka whakarōpūtia e ō rātou roangaru, teitei, tere, me te wā. He mea nui te kaha e haria ana e ngā ngaru ki te horo o te takutai, te kawe paru, me te āhua whānui o ngā takutai moana.
### Ngā Tai
Ko ngā tai he ngaru roa e puta mai ana i te kukume ā-papa o te marama me te rā i runga i ngā moana o te Ao. He rite tonu te piki me te heke o te moana, e mōhiotia ana ko ngā tai teitei me ngā tai iti. Ko ngā āhuatanga tai ko ngā tai kōanga, e puta ana i te wā o ngā marama katoa me ngā marama hou ina tino kaha ngā tai, me ngā tai hou, e puta ana i te wā o ngā marama hauwhā ina ngoikore ngā tai.
He mea nui te ako i ngā tai mō te whakatere, te hī ika, me te mārama ki ngā tukanga takutai. Ko ngā rohe takutai, ngā awaawa, me ngā rohe tai-rua ka tino pāngia e ngā nekehanga tai, ā, ka awe i te tohatoha o ngā rauropi me te huringa o ngā matūkai.
## Te Taunekeneke o te Moana-Āhuarangi
He pūnaha hihiri, matatini hoki te taunekeneke i waenga i te moana me te āhuarangi e awe ana i te āhuarangi me ngā tauira huarere o te ao. Ko ngā taunekeneke moana-āhuarangi e kapi ana i ngā tukanga pēnei i te whakawhiti wera, te whakawhiti hau, me te awe o ngā āhuatanga āhuarangi ki ngā āhuatanga o te moana.
### Whakawhiti Wera
He puna wera nui te moana, e mimiti ana, e penapena ana, e tohatoha ana hoki i te pūngao o te rā. Mā roto i ngā tukanga pēnei i te mimiti, te whakatōtō, me te whakawhiti wera, ka whakawhiti te moana i te wera ki te āhuarangi, e whakahaere ana i ngā tauira āhuarangi me te huarere. Ko te El Niño-Southern Oscillation (ENSO) tētahi tauira pai o te taunekeneke moana-āhuarangi, e whakaatuhia ana hei huringa auau o ngā pāmahana mata moana me ngā pēhanga āhuarangi puta noa i te rohe o te Moana-nui-a-Kiwa equator. Ka taea e ngā huihuinga ENSO te arahi ki ngā huringa nui o ngā tauira huarere, ka pā ki te ua, ngā mahi a te tupuhi, me ngā pāmahana moana puta noa i te ao.
### Whakawhiti Hau me te Huringa Waro
Ka whakawhitiwhiti hau te moana me te āhuarangi, tae atu ki te hāora, te hauhā waro, me ētahi atu hau iti. He mahi nui tā te moana i roto i te huringa waro o te ao, he puna waro nui hoki. Ko te tukanga o te pupuri waro, te wāhi e mimitihia ai te hauhā waro e te wai mata, ka haria ki te moana hohonu mā roto i ngā tukanga koiora me ngā tukanga ā-tinana, ka pā ki ngā taumata CO2 o te āhuarangi, ā, ka whai wāhi ki te whakaiti i te huringa āhuarangi.
## Ngā Pānga ki te Tangata me te Tiaki Moana
Ka piki haere te pānga o ngā mahi a te tangata ki ngā āhuatanga ā-tinana me ngā tukanga o te moana. Ko ngā awe o te tangata ko te mahana haere o te moana nā te huringa āhuarangi, te waikawa o te moana nā te pikinga o te mimiti o te hauhā, me ngā whakarerekētanga o ngā ia moana nā te rewa o te hukapapa o te pito o te moana.
### Te Mahanatanga o te Moana me te Whakawaikawa
He pānga nui tō te mahana o te moana, e hua mai ana i te pikinga o te pāmahana o te ao, ki te whakarōpūtanga wera, te pikinga o te taumata o te moana, me ngā pūnaha rauropi moana. Ka taea e ngā wai te whakarerekē i te tohatoha o ngā momo, te whakararuraru i ngā huringa whakaputa uri, me te whakanui ake i te auau o ngā āhuatanga huarere kino.
Ko te waikawa o te moana, i puta mai i te mimiti o te nui rawa o te CO2 i te āhuarangi, ka heke te taumata pH i roto i te wai moana. Ka taea e te waikawa te whakararu i te hauora o ngā rauropi moana, inā koa ko ērā he anga konupūmā kāponāte, he angaanga rānei, pērā i ngā korara, ngā mokomoko, me ētahi momo plankton.
### Ngā Mahi Tiaki Taiao
Ko te aro atu ki ngā pānga o ngā mahi a te tangata ki te moana me whai mahi tiaki whānui. Ko te whakatū i ngā wāhi tiaki moana, te whakatairanga i ngā mahi hī ika tauwhiro, te whakaiti i ngā tukunga waro, me te whakapakari i te mahi tahi o te ao he mahi nui hei tiaki i te hauora o te moana. He mea nui te rangahau pūtaiao me te aroturuki ki te mārama me te whakaiti i ngā pānga a te tangata ki ngā tukanga ā-tinana o te moana.
## Whakamutunga
Mā te ako moana ā-tinana ka kitea ngā māramatanga nui ki ngā mahi uaua o ngā pūnaha moana o tō tātou ao. He mea nui te mārama ki ngā āhuatanga o ngā ia o te moana, ngā ngaru, ngā tai, me ā rātou taunekeneke ki te āhuarangi hei matapae i ngā rerekētanga āhuarangi, hei tiaki i ngā pūnaha rauropi moana, hei whakahaere hoki i ngā pānga o te tangata ki te taiao moana. Mā te rangahau tonu me ngā mahi tiaki taiao, ka taea e tātou te whai kia tiakina te ora o te moana me te whakarite kia pakari tōna kaha i roto i ngā huringa taiao o te ao.
