Te ngā taura whatu He tino ngoikore ngā waka ruku ki te waikura o te wai moana nā te roa o te rumaki ki roto i te wai moana kukū nui. Hei tāpiri, ka horapa ngā ngota hauwai ki roto i te rauemi karāhe o te muka, ka nui ake te ngaronga o te muka. Nō reira, me ārai ngā taura muka whatu ruku i te hanganga o te hauwai i roto, me te ārai hoki i te urunga o te taura mai i waho. I tēnei wā, ko te hanganga o te taura muka whatu ruku he takai porowhita i te muka whatu i muri i te paninga kotahi, e rua rānei i waenganui, me te takai i tētahi wāhanga whakapakari (he waea maitai) huri noa.
Whakatakotoria he mapi tūturu o te papa moana, kia māmā ake ai te mārama:
He rite tonu te taura muka whatu raro moana ki te paipa hinu; ko te mea nui, ko te rerekētanga nui i waenga i te taura muka whatu raro moana me te taura muka whatu whenua ko tōna "tiakitanga pukupuku." Ko te take e hiahiatia ai he maha ngā paparanga tiaki nā te mea he tino uaua, he kino hoki te taiao raro moana o ngā taura muka whatu raro moana. Ko te tūponotanga tuatahi ko te waikura o te wai. Ko te paparanga polymer o waho o te taura muka whatu raro moana kua hangaia hei ārai i te tauhohenga i waenga i te wai moana me te taura maitai kua whakapakaritia hei whakaputa hauwai. Ahakoa kua waikura te paparanga o waho, ka ārai te ngongo parahi o roto, te paraffin, me te kapia waikawa waro i te hauwai kei kino te muka whatu. Ko te urunga o ngā ngota hauwai ka arahi ki te whakaiti i te tuku muka whatu. Haunga te waikura o te wai moana, ka pāngia hoki ngā taura muka whatu raro moana e te pēhanga o raro moana, ngā āhuatanga taiao (ngā rū whenua, ngā tsunami, me ētahi atu), me ngā āhuatanga tangata (ngā mahi whakaora a ngā kaihao ika). Ki te kore he tiakitanga pukupuku kua whakarei ake, kāore e taea e ngā taura muka whatu raro moana te mahi pono mō ngā wā roa.
Heoi, ahakoa te tino kaha o te tiakitanga, kāore e taea te whakamahi tonu i te taura muka whatu ruku wai, ā, ko tōna roanga mahi he 25 tau noa iho.
