This is a great video from Mission 31 about the midway aquanaut switch, when Liz and I descended to Aquarius. Aquanauts Adam, Andy and Kip first decompressed in Aquarius and then re-surfaced with outstretched arms to the sun. Liz, Matt and I said goodbye to the surface and dove to the bottom of the sea. Liz and I "high-fived" in the water on the dive down together to Aquarius.
