He moku noiʻi e holo ana i lokoKEKAHIUa hoʻomaka koke ke kai e haʻalulu nui, e hāʻule ana kona wikiwiki mai ka 15 knots a i ka 5 knots, ʻoiai ke kai mālie. Ua hālāwai ka poʻe holo moku i ka "mea hoʻokani ʻike ʻole" pohihihi loa o ka moana: nā nalu o loko.
He aha nā nalu o loko? ʻO ka mea mua, e hoʻomaopopo kākou i ka “sandwich wai kai.”
ʻO nā nalu a mākou e ʻike maʻamau ai he "nā nalu i luna" e lele ana a puni ka ʻili; ʻO nā nalu o loko, ma kekahi ʻaoʻao, ua hūnā ʻia i loko o ka hohonu o loko o ka moana-ʻo nā mānoanoa i hana ʻia e nā papa wai. E noʻonoʻo i ka hoʻokaʻawale ʻana o ke kai i "sandwich": ʻo ka papa luna he māmā (ke kiʻekiʻe kiʻekiʻe o ka mahana, haʻahaʻa paʻakai), ʻoiai ke kaumaha o ka papa haʻahaʻa (ka haʻahaʻa haʻahaʻa, kiʻekiʻe salinity). ʻO ka hui ma waena o nā papa ʻelua ʻo ka density. I ka hui ʻana o nā au o ka moana me nā mauna a i ʻole nā mokupuni o lalo, a i ʻole ka makani e hoʻouluulu i ka wai o ka ʻili, e hana ana nā mānoanoa e like me ke kaula i uhuki ʻia, e hana ana i nā nalu o loko e piʻi a hāʻule.
Pehea ka ikaika o nā nalu o loko? Ua hopohopo ʻoe no kēia mau hopena.
Mai manaʻo ʻaʻole hoʻoweliweli ka nalu o loko no ka mea huna hohonu. Hiki i ko lākou ikehu ke "hoʻopunipuni" i nā hana moana:
✅ "Invisible Trap" no Submarines: I ka wā o ke Kaua Honua II, ua hoʻolei ʻia nā submarine i komo i nā ʻāpana nalu o loko i ka ʻili e nā au kūpikipiki, e hōʻike ana i kā lākou mau pahuhopu. I kēia lā, nānā nā submarine i "nā wānana nalu o loko" ma mua o ka holo ʻana e pale aku i nā wahi pōʻino.
✅ "Ka Hoʻouna ʻana i nā meaʻai" no nā ʻĀina lawaiʻa: Ke piʻi ka nalu o loko, huki lākou i nā meaʻai (e like me ka phosphates a me ka nitrates) mai ke kai a i ka ʻili, e hānai ana i ka plankton. Nui nā lawaiʻa ma ke Kai Kina Hema o koʻu ʻāina e hilinaʻi nei i nā nalu o loko e "hānai" i ka iʻa!
✅ "Invisible Test" no Marine Engineering: Hiki ke hoʻopōʻino ʻia nā uwea submarine a me nā kahua ʻeli ʻaila e ke au inā e hālāwai lākou me nā nalu ikaika o loko. Ma hope o ka 2010 Gulf of Mexico oil spill, ua nānā pono nā kānaka ʻepekema i ka hopena o nā nalu o loko i ka laha ʻana o nā ʻaila ʻaila.
Pehea e ʻike ʻia ai nā "nā nalu o loko"?
I ka wā ma mua, ua hilinaʻi nā poʻe holo moku i ka "manaʻo" no nā nalu o loko, akā i kēia manawa ua loaʻa nā ʻenehana kiʻekiʻe:
● ʻIke mamao Satellite: Ma ka nānā ʻana i nā loli liʻiliʻi o ka mahana a me ke kiʻekiʻe o ka ʻilikai, hiki iā mākou ke "ʻike" i nā nalu o loko ma lalo o ka ʻili (e like me ka loaʻa ʻana o kahi mea ma kona aka);
● Nā ʻauamo submarine: E hoʻopaʻa i nā mea nānā i lalo ma kahi kokoke i ka thermocline e hoʻopaʻa i ka amplitude a me ka wikiwiki o nā nalu i loko i ka manawa maoli;
● Nā lopako ma lalo o ka wai: Ua hopu lākou i nā kiʻi wehewehe kiʻekiʻe o nā nalu o loko e hoʻoneʻe ana i ke kaiKEKAHIKai.
Hoʻokumu ʻo Frankstar i ka nānā ʻana i ka nalu moana, hanamea ike loeaanā hāʻina holo.
Me ka hoʻomohala ʻana i ka nānā ʻana i ke kaiapuni moana, ka ʻenekinia moana, a me ka ikehu kai hou, e lilo ana nā lako ʻikepili ʻikepili pololei a hilinaʻi i mea koʻikoʻi. Ma ke ʻano he mea hoʻomohala ʻoihana o nā mea ʻike nalu a me nā buoys, ua kūpaʻa ʻo Frankstar i ka hoʻomohala ʻana i nā huahana kiʻekiʻe, maʻalahi e hoʻopili i hiki ke hoʻololi i nā kūlana kai paʻakikī, a hoʻoikaika ikaika i kā lākou noi ʻana i ka noiʻi ʻepekema, ʻenekinia, ikehu, a me nā kula ʻē aʻe.
E kipa mai i ko makoupūnaewele puni honuano ka ʻike hou aku o nā huahana, nā noiʻi hihia, a me nā pepa keʻokeʻo ʻenehana.
