Meren pohjassa olevia rikkauksia on mahdollista hyödyntää, mutta siihen liittyy riskejä. Valtamerten pohja on löysää saviliejua, jossa on paikoitellen kovia kuoria, sanoo @jvirtasa @GTK_FI “Jos kovat pinnat poistetaan pohjasta, lajiston määrä vähenee.” kauppapolitiikka.fi/merten-rikkauk…

Eurooppa käyttää viidesosan maailman metalleista, mutta tuottaa vain 3 %. Esim. koboltti on listattu EU:n kriittiseksi mineraaliksi. “Erään laskelman mukaan merten pohjassa on sata miljoonaa tonnia kobolttia tai ehkä ylikin”, kertoo @jvirtasa @GTK_FI. kauppapolitiikka.fi/merten-rikkauk…

@AnttiJRissanen1 Mielenkiintoista. Saa nähdä varmistuuko esitetty hydrolyysi happea tuottavaksi prosessiksi noduleissa, vai ovatko asialla sittenkin mikrobit.

@jvirtasa Jotkut metaania hapettavat bakteerit tuottavat metanobaktiineita, joiden reagointi metallien kanssa voi myös johtaa veden pilkkoutumiseen vapaaksi hapeksi. journals.asm.org/doi/10.1128/ae…

Syvänmeren rautamangaaninodulit tuottavat happea hydrolyysillä. Huippumielenkiintoinen ja tärkeä löytö, mutta samalla hämmentävä osoitus siitä, miten valtamerten syvyyksissä on yhä löydettävissä eliökunnan olemassaolon kannalta keskeisiä ilmiöitä. yle.fi/a/74-20100994
