Cette nouvelle source de silicium dissous vient d'être découverte par plusieurs chercheurs de l'Observatoire Midi-Pyrénées, dont Sébastien Fabre de l'IRAP. Elle s'ajoute à celles que constituent les fleuves, les décharges d’eaux souterraines et les sources hydrothermales.En quoi la <a href="https://astrodon.social/tags/PompeBiologique" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#PompeBiologique</a>, mécanisme grâce auquel l’océan capture et séquestre le <a href="https://astrodon.social/tags/CO2" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#CO2</a> atmosphérique, s'en trouve-t-elle affectée ?
