This video highlights Team Twilight Zone (TZ) on their third deep dive (250 feet/76.2 meters deep on Trimix). Team TZ is ascending in unison up the coral wall from their target depth and beginning their decompression schedule. You can see the team members wearing double tanks on their backs (breathing trimix) with stage bottles under their arms (containing enriched air nitrox). After the dive is complete, Team TZ head back to the lab to see their collection. Marc Slattery, Cristina Diaz, Deb Gochfeld and Julie Olson are sorting out the different samples. Marc and Cristina are pleasantly surprised when they come across a sponge that they have never seen before! Video courtesy of of the Twilight Zone Expedition Team 2007, NOAA-OE.
