Ubwato bw'ubushakashatsi buri mu bwatoBAMWEInyanja yatangiye gutigita cyane, umuvuduko wayo uva kuri 15 knots ugera kuri 5 knots, nubwo inyanja yari ituje. Abakozi bayo bahuye n' "umukinnyi utagaragara" w'amayobera cyane mu nyanja: imiraba y'imbere mu nyanja.

Imiraba y'imbere ni iki? Ubwa mbere, reka dusobanukirwe "sandwich yo mu mazi yo mu nyanja."

Imiraba dusanzwe tubona ni "imiraba yo hejuru" izenguruka hejuru y'inyanja; imiraba yo imbere, ku rundi ruhande, iba yihishe mu bucucike bw'imbere bw'inyanja—ubucucike bugizwe n'ibice by'amazi. Tekereza ku mazi yo mu nyanja nk'aho agabanyijemo "sandwich": urwego rwo hejuru ni rworoshye (ubushyuhe bwinshi, umunyu muke), mu gihe urwego rwo hasi ruremereye (ubushyuhe buri hasi, umunyu mwinshi). Aho ibice bibiri bihurira ni ubucucike. Iyo imiraba yo mu nyanja igongana n'imisozi cyangwa ibirwa biri munsi y'amazi, cyangwa iyo umuyaga uhushye amazi yo hejuru, ubucucike bukora nk'umugozi ucitse, bigatuma imiraba yo mu nyanja izamuka ikamanuka.

Imiraba y'imbere mu kirere ifite imbaraga zingana iki? Nta gushidikanya ko uhangayikishijwe n'izi ngaruka.

Ntugatekereze ko imiraba y'imbere mu mazi idafite ikibazo kuko gusa yihishe mu kirere. Ingufu zayo zishobora "guhindura" ibikorwa byo mu mazi byoroshye:

✅ “Umutego utagaragara” ku bwato butwara amazi: Mu Ntambara ya Kabiri y'Isi Yose, ubwato butwara amazi bujya mu turere tw’imiraba y’imbere bwajugunywe hejuru n’imiraba ikaze, bigashyira ahagaragara intego zabo. Muri iki gihe, ubwato butwara amazi bugenzura “ibizaba ku miraba y’imbere” mbere yo kugenda mu bwato kugira ngo hirindwe ahantu hateje akaga.

✅ “Gutanga intungamubiri” ku butaka bw’uburobyi: Iyo imiraba y’imbere mu nyanja ibaye myinshi, ikura intungamubiri (nka fosfeti na nitrati) mu mazi yo mu nyanja ikagera hejuru, igatunga plankton. Uburobyi bwinshi mu Nyanja y’Amajyepfo y’Ubushinwa mu gihugu cyanjye bushingiye ku miraba y’imbere mu nyanja kugira ngo “igaburire” amafi!

✅ “Ikizamini Kitagaragara” cy’Ubwubatsi bw’Amato: Insinga zo munsi y’amazi n’ibikoresho byo gucukura peteroli bishobora kwangizwa n’amazi mu gihe bihuye n’imiraba ikomeye y’imbere mu mazi. Nyuma y’isuka rya peteroli ryo mu Kigobe cya Megizike mu 2010, abahanga mu bya siyansi bakurikiranye by’umwihariko ingaruka z’imiraba y’imbere mu mazi ku ikwirakwira ry’imiraba ya peteroli.

Ni gute "imiraba y'imbere" ishobora kugaragara?

Mu gihe cyashize, abakozi bishingikirizaga ku "kumva" imiraba y'imbere mu bwato, ariko ubu ikoranabuhanga rigezweho rirahari:

● Gupima ikirere hakoreshejwe ikoranabuhanga rya satelite: Dukurikije impinduka zigaragara mu bushyuhe n'ubutumburuke bw'inyanja, dushobora "gupima" imiraba y'imbere munsi y'ubuso (nk'uko umuntu abona ikintu mu gicucu cyacyo);

● Amato yo mu mazi: Shyira ibikoresho byo kugenzura hafi ya thermocline kugira ngo wandike uburebure n'umuvuduko w'imiraba y'imbere mu gihe nyacyo;

● Robot zo munsi y'amazi: Zafashe amashusho y'imiraba yo mu mazi atuma amazi yo mu nyanja agenda mu buryo butangaje muriBAMWEInyanja.

Frankstar inzobere mu kugenzura imiraba y'inyanja, ikorasensor y'umwuganaibisubizo bya boya.

Bitewe n’iterambere ry’igenzura ry’ibidukikije byo mu mazi, ubwubatsi bw’amazi yo mu nyanja, n’ingufu zisubira mu nyanja, ibikoresho byo kubona amakuru y’imigezi neza kandi byizewe birimo kuba ibikorwa remezo by’ingenzi. Nk’umuhanga mu guteza imbere ibikoresho byo gupima imigezi n’ibintu biyikikije, Frankstar yiyemeje guteza imbere ibikoresho bikora neza kandi byoroshye gukoresha bishobora guhuza n’imiterere y’inyanja igoye, kandi ikamamaza ikoreshwa ryabyo mu bushakashatsi bwa siyansi, ubwubatsi, ingufu, n’ibindi.
