Umkhumbi wocwaningo ohamba ngomkhumbiABANYEUlwandle lwaqala ukuzamazama ngamandla ngokuzumayo, isivinini salo sehla sisuka kumafindo ayi-15 saya kumafindo ama-5, naphezu kolwandle oluzolile. Ithimba lahlangana "nomdlali ongabonakali" ongaqondakali kakhulu olwandle: amagagasi angaphakathi.

Ayini amagagasi angaphakathi? Okokuqala, ake siqonde “isangweji lamanzi olwandle.”

Amagagasi esivame ukuwabona “amagagasi angaphezulu” agxumagxuma phezu kolwandle; amagagasi angaphakathi, ngakolunye uhlangothi, afihliwe ngaphakathi kobuningi bangaphakathi bolwandle—ubuningi obakhiwe yizingqimba zamanzi. Cabanga ngamanzi olwandle njengahlukaniswe “ngesangweji”: ungqimba olungaphezulu lulula (izinga lokushisa eliphakeme, usawoti ophansi), kuyilapho ungqimba olungezansi lusinda kakhulu (izinga lokushisa eliphansi, usawoti ophakeme). Ukuhlangana phakathi kwezingqimba ezimbili kuwubuningi. Lapho imisinga yolwandle ingqubuzana nezintaba noma iziqhingi ezingaphansi kwamanzi, noma lapho imimoya ishukumisa amanzi angaphezulu, ubuningi busebenza njengentambo eqoshiwe, idala amagagasi angaphakathi akhuphuka futhi ehle.

Amagagasi angaphakathi anamandla kangakanani? Ukhathazekile ngempela ngalezi zigameko.

Ungacabangi ukuthi amagagasi angaphakathi awayona ingozi ngoba nje efihliwe ekujuleni. Amandla awo angakwazi “ukulawula” kalula imisebenzi yasolwandle:

✅ “Ugibe Olungabonakali” Lwemikhumbi-ngwenya: Ngesikhathi seMpi Yezwe II, imikhumbi-ngwenya eyayingena ezindaweni zamagagasi angaphakathi yaphonswa phezulu yimisinga enamandla, yadalula izinhloso zayo. Namuhla, imikhumbi-ngwenya ihlola “izibikezelo zamagagasi angaphakathi” ngaphambi kokuhamba ukuze igweme izindawo eziyingozi.

✅ “Ukulethwa Kwezakhamzimba” Ezindaweni Zokudoba: Lapho amagagasi angaphakathi ekhuphuka, adonsa izakhamzimba (njenge-phosphates nama-nitrate) kusukela phansi kolwandle kuya phezulu, ondla i-plankton. Izindawo eziningi zokudoba oLwandle lwaseNingizimu China ezweni lakithi zithembele kumagagasi angaphakathi ukuze “zondle” izinhlanzi!

✅ “Ukuhlolwa Okungabonakali” Kobunjiniyela Basemanzini: Izintambo zangaphansi kolwandle kanye nezinkundla zokumba uwoyela zingonakaliswa yimisinga uma zihlangana namagagasi angaphakathi aqinile. Ngemva kokuchitheka kukawoyela eGulf of Mexico ngo-2010, ososayensi baqapha ngqo umthelela wamagagasi angaphakathi ekusabalaleni kokuchitheka kukawoyela.

"Amagagasi angaphakathi" angabonakala kanjani?

Esikhathini esidlule, amalungu eqembu ayethembele “ekuzizweleni” amagagasi angaphakathi, kodwa manje ubuchwepheshe obuphezulu buyatholakala:

● Ukuzwa okukude kwesathelayithi: Ngokubheka izinguquko ezincane ekushiseni kolwandle kanye nokuphakama, singakwazi "ukunquma" amagagasi angaphakathi ngaphansi kobuso (njengokuthola into ngomthunzi wayo);

● Ama-buoy angaphansi kolwandle: Faka imishini yokuqapha eduze kwe-thermocline ukuze urekhode ubukhulu kanye nesivinini samagagasi angaphakathi ngesikhathi sangempela;

● Amarobhothi angaphansi kwamanzi: Athwebule izithombe ezicacile zamagagasi angaphakathi aqhuba ukunyakaza kwamanzi olwandle eABANYEUlwandle.

I-Frankstar igxile ekuqapheni amagagasi olwandle, idalainzwa yobungcwetifuthiizixazululo ze-booy.

Ngokuthuthukiswa kokuqapha imvelo yasolwandle, ubunjiniyela basolwandle, kanye namandla avuselelekayo olwandle, imishini yokuthola idatha yamagagasi enembile nethembekile iba yingqalasizinda ebalulekile. Njengonjiniyela ochwepheshe wezinzwa zamagagasi nama-buoy, iFrankstar izibophezele ekuthuthukiseni imikhiqizo esebenza kahle kakhulu, okulula ukuyihambisa engazivumelanisa nezimo zolwandle eziyinkimbinkimbi, futhi ikhuthaze ngenkuthalo ukusetshenziswa kwayo ocwaningweni lwesayensi, ubunjiniyela, amandla, kanye neminye imikhakha.
