I subacquei che si immersero sono: Giorgio Bergamo, Giulio Melegari, Enzo Zarafa e Gianni Risso in vesto di fotografo. Tutti indossavano mute umide da 6,5 mm. Sotto la direzione del Dottor Andrea Ravara, parteciparono all'eccezionale evento scientifico: il Dottor Ugo Fabris (reografo) il prof. Mario Trasino (laboratorista), il dott Pietro Schenone (elettrocardiolog), l'ing. Vincenzo Tagliasco (bionico). Nell'acqua lattea e con temperatura prossima allo O, furono praticate simultaneamente ai sub: elettrocardiografie, reografie periferiche del cranio e degli arti mediante cavi coassiali del tutto simili quelli che usavano gli astronauti. Appena riemersi tutti i sub furono sottoposti anche agli esami del sangue. Dalle ricerche effettuate scaturirono risultati molto interessanti che furono richiesti da istituti di ricerca di tutto il Mondo, compresi: Accademia delle Scienze dell'Unione Sovietica e NASA. La spedizione al Lago del Miage fu organizzata da Mario Polleri e Gianni Risso con la piena collaborazione del Comune di Courmayeur. </p> <div class="mw-heading mw-heading2"><h2 id="Note">Note</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Immersione_in_quota&veaction=edit&section=8" title="Modifica la sezione Note" class="mw-editsection-visualeditor"><span>modifica</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=Immersione_in_quota&action=edit&section=8" title="Edit section's source code: Note"><span>modifica wikitesto</span></a><span class="mw-editsection-bracket">]</span></span></div> <div class="mw-references-wrap"><ol class="references"> <li id="cite_note-FIPSAS-1"><a href="#cite_ref-FIPSAS_1-0"><b>^</b></a> <span class="reference-text"><cite class="citation web" style="font-style:normal"> FIPSAS, <a rel="nofollow" class="external text" href="https://web.archive.org/web/20070928100411/http://www.fipsas.it/area/doc_cdas/quota.pdf"><span style="font-style:italic;">Immersioni in quota</span></a> (<span style="font-weight: bolder;
