Gukurikirana ubuzima bw'inyanja hakoreshejwe icyuma gipima ubuziranenge bw'ibinyabutabire (photo chemical sensor).

Ogisijeni ni ingenzi mu kubaho kw'abantu ndetse n'ibinyabuzima byo mu mazi. Twakoze ubwoko bushya bw'icyuma gipima urumuri gishobora kugenzura neza ubwinshi bwa ogisijeni mu mazi yo mu nyanja no kugabanya ikiguzi cyo gukurikirana. Ibi bikoresho byageragejwe mu turere dutanu kugeza kuri dutandatu tw'inyanja, hagamijwe guteza imbere umuyoboro w'igenzura ry'inyanja - "Ocean Nerve" - ​​nyuma yo gukora ibikoresho byinshi. Ibi byitezwe ko bizatanga iterambere mu igenzura rirambye ry'ibidukikije byo mu mazi no gucunga umusaruro w'uburobyi.

Bitewe n'ibintu nk'ubwiyongere bw'abaturage, imihindagurikire y'ikirere, n'ihumana ry'ibidukikije, ubwinshi bwa ogisijeni (izwi cyane nka "ogisijeni yashongeshejwe" cyangwa "DO") mu mazi yo mu nyanja buragabanuka, bigatera imiterere mibi, kutabyara, ndetse no gupfa kw'ibinyabuzima byinshi byo mu nyanja. Ibi biteza akaga gakomeye ku rusobe rw'ibinyabuzima n'uruhererekane rw'ibiribwa. Abahanga mu bya siyansi bagiye biga urugero rwa ogisijeni mu nyanja. Ariko kubera impinduka zihuse muri DO ahantu hatandukanye no mu gihe gito, ibi bisaba ibikoresho byinshi byo mu bwoko bwa sensor. Byongeye kandi, guhumanya ibidukikije byongera cyane ikiguzi cyo kubungabunga sensor. Ibi biteza imbogamizi ikomeye mu kugenzura DO mu mazi yo mu nyanja mu gihe kirekire, mu buryo bunini.

Ikomoka kuri "Ocean Nerve", igamije kubaka uburyo bwo kugenzura inyanja bunoze kandi buhendutse bukoresheje "DO sensors". Isoko y'urumuri rwa ultraviolet rwa sensor itera impinduka hagati y'ibikoresho byo kumva kuri filime na DO mu mazi yo mu nyanja. Amakuru yashyizwe mu bikoresho by'ikipe bikorera ku butaka, byanditse impinduka mu rugero rwa ogisijeni mu mazi yo mu nyanja mu gihe nyacyo. Itsinda rishya ry'ibikoresho byo kumva ogisijeni byashongeshejwe rituma habaho gukurikirana mu buryo nyabwo kandi mu gihe kirekire urugero rwa ogisijeni mu mazi yo mu nyanja. Bigabanya ikiguzi cyo kubungabunga.
