Pono ka oxygen i ke ola o ke kanaka a me ke ola moana. Ua hoʻomohala mākou i kahi ʻano hou o ka ʻike māmā e hiki ke nānā pono i ka ʻike o ka oxygen i loko o ke kai a hoʻemi i nā kumukūʻai nānā. Ua hoʻāʻo ʻia nā mea ʻike ma ʻelima a ʻeono mau wahi moana, me ka pahuhopu o ka hoʻomohala ʻana i kahi pūnaewele nānā moana - "Ocean Nerve" - ma hope o ka hana nui ʻana o nā mea ʻike. Manaʻo ʻia kēia e alakaʻi i nā holomua i ka nānā ʻana i ke kaiapuni moana a me ka hoʻokele hana lawaiʻa.

Ma muli o nā mea e like me ka ulu ʻana o ka heluna kanaka, ka hoʻololi ʻana i ke aniau, a me ka haumia o ke kaiapuni, e emi iho ana ka neʻe ʻana o ka oxygen (i ʻike mau ʻia ʻo "oxygen dissolved" a i ʻole "DO") i loko o ke kai, ka hopena o ka malformation, sterility, a me ka make ʻana o nā ʻano ʻano moana he nui. He mea weliweli kēia i ka kaiaola holoʻokoʻa a me ke kaulahao meaʻai. Ke aʻo nei nā kānaka ʻepekema i ka pae o ka oxygen ma ka moana. Akā ma muli o ka loli wikiwiki o DO ma nā wahi like ʻole a me ka manawa pōkole, pono kēia i nā mea ʻike he nui. Eia kekahi, hoʻonui nui ka fouling biological i ke kumukūʻai mālama o ka sensor. He paʻakikī nui kēia no ka nānā ʻana i ka wai kai DO no ka wā lōʻihi.
Loaʻa ʻia mai "Ocean Nerve", manaʻo ia e kūkulu i kahi ʻōnaehana nānā moana kūpono a haʻahaʻa me nā "DO sensors". Hoʻomaka ke kumu kukui ultraviolet o ka mea ʻike i ka hopena photochemical ma waena o ka mea ʻike ma ke kiʻiʻoniʻoni a me ka DO i loko o ke kai. Ua hoʻouna ʻia ka ʻikepili i nā lako ʻāina o ka hui, nāna i hoʻopaʻa i nā loli i ka pae o ka oxygen i loko o ke kai i ka manawa maoli. ʻO kahi hanauna hou o nā mea ʻike oxygen i hoʻoheheʻe ʻia e hiki ai i ka manawa maoli, ka nānā ʻana i nā pae oxygen i ka wai kai. Hoʻemi i nā koina mālama.
