ʻO ka lua o ka moana nui ka Moana ʻAkelanika. ʻO ka papa kai ma lalo o ka wai i hoʻokumu ʻia i nā manawa like ʻole. Hoʻomaka ka hoʻokumu kai i ka wā Mesozoic, i ka wā i hoʻokaʻawale ai ka supercontcent i mau ʻāina nui, i neʻe a a ʻo ka hopena ua hoʻokumu ʻia ka lithosfer oceanic mua. Eia kekahi, ua hoʻokumu ʻia nā mokupuni a me nā pae ʻāina, kahi i kōkua ai i kahi hoʻololi o ke kahakai a me ka wahi o ka Moana ʻAkelanika. I nā makahiki i hala aku nei he 40 miliona, ke wehe nei ke kīʻaha kai ma kahi axis rift, e hoʻomau nei a hiki i kēia lā, mai ka neʻe ʻana o nā pā i kahi wikiwiki i kēlā me kēia makahiki.
ʻO ka mōʻaukala o ke aʻo ʻana o ka Moana ʻAkelanika
Ua ʻimi ʻia ka Moana ʻAkelanika e nā poʻe mai ka wā kahiko. ʻO nā ala kalepa nui a ka poʻe Helene a me nā Carthaginians, nā Poenikia, a me nā Roma i hele aʻe ma waena ona. I ke au waena, holo aku ka poʻe Noremana i ke kahakai o Greenland, ʻoiai aia kekahi mau kumu e hōʻoia ana ua hala loa lākou i ke kai a hōʻea i nā kapakai o ʻAkau ʻAmelika.
I ke au o nā ʻike ʻāina nui, ua ʻauʻau nā huakaʻi i ka moana.

I ka mua, ua manaʻo ʻia ua hele nā luina i ka moana, a wehe i kahi ala hou i ʻInia, akā ma hope loa ua ʻike ʻia ʻo New Earth kēia. ʻO ka ulu ʻana o nā kapakai ʻākau o ka ʻAkelanika i hala i ka ʻumikūmāono a ʻumikūmāhiku mau kenekulia, ua huki ʻia nā palapala ʻāina, ke kaʻina o ka ʻohi ʻana i ka ʻike e pili ana i ka wahi o ka wai, nā helehelena a me nā wikiwiki a me nā wikiwiki o ka moana e holo.
I nā kenekulia ʻumikūmāwalu a me ʻumikūmāiwa, ʻo ka ulu nui a me ke aʻo ʻana o ka Moana ʻAkelanika na G. Elis, J. Cook, I. Kruzenshtern, E. Lenz, J. Ross. Ua aʻo lākou i ke kaʻina hana o ka wai a hoʻolālā i nā ʻaoʻao o ke kahakai, ua aʻo i ka hohonu o ka moana a me nā hiʻohiʻona o ka lalo.
Mai ke kenekulia iwakālua a hiki i kēia lā, ua mālama ʻia ka noiʻi kumu ma ka Moana ʻAkelanika. ʻO kēia kahi noiʻi kaiana moana, me ke kōkua o nā pono hana kūikawā, e ʻae nei e hoʻopaʻa ʻaʻole wale i ke kahe wai o ka wahi o ka wai, akā ʻo ka topography o lalo, flora o ka wai a me nā holoholona. Nānā pū kekahi pehea ka hopena o ke aniau o ka moana i ka wā ʻenekala.
No laila, ʻo ka Moana ʻAkelanika ke kaiaolaola nui loa o ko mākou honua, ʻāpana o ka Moana Honua. Pono e aʻo ʻia, no ka mea he hopena nui kona i ke kaiapuni, a i ka hohonu o ke kai e wehe ai i kahi honua kūpaha kupaianaha.
