I waenganui i te tipu haere o te hiahia mō ngā raraunga tika mō te moana, te āhuarangi, me ngā rauemi taiao, kei te noho ko ngā waka rangahau hangarau teitei hei pou tokomanawa mō te pūtaiao hou. Ehara ēnei waka i te "waka nui" noa iho e kawe ana i ngā kairangahau ki waenganui o te moana, engari he taiwhanga nekeneke kei a rātou ngā pūoko matatau, ngā pūnaha whakatere tika, ngā taputapu mahere papa moana, me ngā whakaurunga rorohiko mō te tukatuka raraunga wā-tūturu. Mā ēnei āheinga, ka taea e ngā waka rangahau te whakautu i ngā pātai nui: me pēhea te pānga o te huringa āhuarangi ki te moana, te āhua o ngā rauropi wai, me pēhea te mahere i ngā pūmanawa me ngā mōrearea i ngā rohe moana.
Te Tūranga o ngā Waka Rangahau i te Wā Raraunga
Ko ngā rangahau moana me tirotiro tika, kāore e taea te whakakapi e ngā amiorangi, e ngā teihana takutai rānei. Ka taea e ngā amiorangi te aroturuki i ngā pāmahana o te mata o te moana, i ngā tauira o te ia nui rānei, engari he maha ngā āhuatanga e puta ana i raro i te mata: ngā taumata matūkai, te kounga o te wai, te tohatoha kirihou moroiti, ngā hapori plankton, te āhua matatini o te papa moana rānei. Ko ngā waka rangahau ngā tūāpapa matua mō te kohi tauira, e tango ana i ngā ine poutū mai i te mata ki te hohonutanga o ngā mano mita, ā, e whakarite ana kia tutuki te kohikohinga raraunga i ngā paerewa pūtaiao pakari.
I tēnei ao raraunga o ēnei rā, kua whānui haere te mahi a ngā waka rangahau. Ehara i te mea ko te kohikohi raraunga anake tā rātou, engari ko te whakarite hoki mō te tātari. Mā ngā pūnaha whakawhitiwhiti kōrero amiorangi ka taea te tuku tere atu i ētahi tirohanga ki uta, ā, ka taea e te tīma o runga te whakamana me te mahi i ngā whakatikatika tuatahi. Ka tere ake te tukanga rangahau, inā koa mō ngā kaupapa e hiahia ana kia tere te urupare, pērā i te turuturu hinu, te mā o te korara, ngā rerekētanga rānei o te pāmahana o te moana.
Pūnaha Whakatere Tika me te Pūnaha Tūnga Hihiri
Ko tētahi whanaketanga nui i roto i te hangarau rangahau waka kei roto i te whakatere tika. Mā te tautoko o te GPS rerekē, ngā pūnaha whakatere inertial, me ngā pailate aunoa hou, ka taea e ngā waka te whai i ngā ara rangahau me te tino tika. He mea nui tēnei ina whakahaerehia he mahere kaukau, he ine pou wai rānei, nā te mea ka taea e te he o te whakatakotoranga te arahi ki ngā raraunga kore e ōrite, kāore rānei e taea te whakataurite puta noa i ngā wā.
Hei tāpiritanga, he maha ngā waka rangahau hou e whakaatu ana i te tūnga hihiri (dynamic positioning - DP), he pūnaha e pupuri aunoa ana i te tūranga o te waka, e pupuri ana rānei i tētahi tūranga motuhake mā te whakarerekē i ngā poroporo me ngā pana. He tino whai hua te DP ina whakahaere ana i ngā taputapu taumaha pēnei i ngā ROV (Remotely Operated Vehicles), e whakaheke ana i ngā CTD (Conductivity-Temperature-Depth), e kohikohi ana rānei i ngā tauira paru. I roto i ngā āhuatanga o te ngaru me te hau e rerekē ana, ka āwhina te DP ki te pupuri i te pumau o te mahi, e whakarite ana i te haumaru me te kounga o ngā raraunga.
Ngā Pūoko Moana: Ngā "Āhuatanga" o ngā Waka Rangahau
He maha ngā pūoko kei roto i ngā waka rangahau hangarau matatau hei whakamahi hei "pūoko" hei pānui i ngā āhuatanga o te moana. Ko tētahi o ngā taputapu tino noa ko te CTD rosette, e ine ana i te kawe hiko (mō te tote), te pāmahana, me te hohonu. He maha ngā wā ka honoa ngā CTD ki ngā pounamu Niskin hei whakamātautau i te wai i ngā hohonutanga motuhake, e āhei ai ngā kairangahau ki te whakamātautau i te hāora rewa, te pH, te chlorophyll, me ētahi atu tawhā matū.
Haunga ngā CTD, ko ngā waka rangahau he mea whakamahi i ngā Acoustic Doppler Current Profilers (ADCP) hei ine i te tere me te ahunga o ngā ia moana i ngā hohonutanga rerekē. He mea nui ngā raraunga o nāianei mō ngā tauira āhuarangi, ngā matapae nekehanga parahanga, me ngā rangahau hekenga koiora moana. Ka aroturukihia hoki e ngā pūoko āhuarangi whakauru te hau, te pēhanga hau, te haumākū, me te hihi o te rā, nā te mea he mea nui ngā taunekeneke o te āhuarangi-moana ki te maha o ngā āhuatanga āhuarangi.
Te Mahere Papa Moana: Ngā Hiko Maha me te Matawai-taha Sonar
Ko te hangarau mahere tētahi o ngā kaha matua o ngā waka rangahau hou.

He tino whai hua ngā ROV mō te tūhura i ngā hohonutanga he tino morearea mō ngā ruku.
Haunga ngā ROV, kei reira anō ngā AUV (Ngā Waka I raro i te Wai Aunoa) e neke motuhake ana i ngā huarahi kua whakaritea. He maha ngā wā ka whakamahia ngā AUV hei tirotiro i ngā wāhi nui, hei mahere i te papa moana, hei ine rānei i ngā tawhā o te pou wai me te kore e hiahiatia he mana whakahaere tonu. Ko te waka rangahau te "waka matua" e whakarewa ana, e tiki ana hoki i te AUV, ā, he pokapū whakahaere hoki mō ngā tango raraunga me te tiaki.
Ehara i te mea kei raro i te wai anake, engari kei te tīmata hoki ngā waka rangahau ki te whakamahi i ngā waka rererangi rererangi hei mahere takutai moana, hei aroturuki i te turuturu hinu, me te aroturuki i ngā rohe toka korara i te teitei iti. Nō reira, kei te huri ngā waka rangahau hou hei tūāpapa whakauru mō ngā rangahau maha-rohe: moana, rangi, me te takutai moana.
Te Taiwhanga o Runga me te Rorohiko Wā-Tūturu
He maha ngā wāhi taiwhanga o ngā waka hangarau matatau: he taiwhanga maku mō ngā tauira koiora me ngā tauira matū, he taiwhanga maroke mō ngā taputapu me ngā rorohiko, me te wāhi rokiroki tauira e whakahaeretia ana te pāmahana. Mā ēnei whare ka taea te tātari tuatahi i runga i te kaipuke, ka taea ai e ngā kairangahau te whakarerekē i ngā rautaki rangahau i runga i ngā kitenga tuatahi.
Kei te tere haere te whanaketanga o ngā rorohiko i runga i te kaipuke. Mā ngā pūnaha rokiroki raraunga nui-kaha, ngā tūmau tukatuka sonar, me ngā pūmanawa whakatauira o nāianei ka taea te whakaatu raraunga i te wā tūturu. He mea nui tēnei painga ina he nui te utu o ngā rangahau, ā, he iti hoki te wā—ka taea e ngā kairangahau te whakarite i te kounga o ngā raraunga i mua i te hokinga o te kaipuke ki te tauranga.
Haumaru, Whai Hua Pūngao, me ngā Hangarau Ā-Taiao
Kua hangaia ngā waka rangahau hou ki ngā paerewa haumaru teitei: ngā pūnaha aroturuki miihini, te kimi ahi, ngā tikanga whakawātea, me te whakangungu kaimahi pakari. Hei tāpiri, he mea nui te whai huatanga o te pūngao. He maha ngā waka hou e whakamahi ana i ngā hoahoa anga waka e whai hua ana ki te wahie, ngā pūnaha whakatere ranu, me te whakahaere pūngao atamai hei whakaiti i ngā tukunga.
Kei te whakamahia hoki ngā hangarau e pai ana ki te taiao mō te maimoatanga wai para, te whakamahi i ngā peita ārai-paru haumaru ake, me te whakaiti i te haruru o raro i te wai. Ka taea e te haruru o ngā kaipuke te whakararuraru i ngā kararehe moana, ā, ka pā ki te kounga o ngā raraunga oro. Nō reira, kua hangaia ētahi kaipuke rangahau ki te "hangarau kaipuke marino" kia marino ake ai i te wā e ine ana i ngā mea ora, e tirotiro ana rānei i ngā koiora.
Ngā Wero me te Ao o Ngā Waka Rangahau
Ahakoa te hiranga o ēnei waka rangahau hangarau matatau, he nui te utu mō te hanga me te whakahaere i ngā waka rangahau hangarau matatau. Haunga te tiaki auau, me whakatikatika me te whakahou i ngā pūmanawa ngā pūoko me ngā karetao. Ko tētahi atu wero ko te wātea o ngā rauemi tangata: me whai kaimahi me ngā tohunga hangarau whakangungu te whakahaere i tētahi pūnaha maha-rama, AUV, DP rānei.
Ā tōna wā, tera pea ka nui haere te hononga o ngā waka rangahau ki ngā whatunga tirotiro ā-ao. Ka taea te whakakotahi i ngā raraunga mai i ngā waka me ngā pōito aunoa, ngā waka rere, me ngā amiorangi hei hanga i tētahi māramatanga whānui mō te moana. E matapaetia ana ka piki ake te whakamahinga o te mātauranga horihori, hei tauira, hei kite i ngā tauira rerekē i roto i ngā raraunga sonar, hei tautuhi i ngā momo mai i ngā whakaahua kāmera o raro i te wai, hei arotau rānei i ngā huarahi rangahau kia pai ake ai te whai huatanga.
