Each year the USC Hyperbaric Chamber on Catalina holds a fundraiser day that involves tours of the facility and an opportunity to get a few dives in. It happens to be on a Wednesday when theoretically us gainfully employed types should be working but that's why vacation days were invented.

At least for those of us who aren't schoolteachers.  Jen was unable to get away from school and in the end it ended up being just Jack Kieffer and I driving out to San Pedro before dawn.


The hyperbaric chamber is used for treatment of decompression illness (aka the bends) which are a risk involved in diving due to the amount of nitrogen which is dissolved in your blood while breathing compressed air at depth. So this is both a great way to get to see the chamber without a potentially serious medical complication and also serves as a fundraiser which helps keep the place operational.
