I need a durable, outdoorsy camera that has good image quality!?

Hey all,

I'm a college student who is about to do some huge traveling around the world, including studying abroad. I am also from Hawaii and love surfing, and go to a school near a mountain and love snowboarding. Most of the cameras I have, survive snowboarding so I'm not too worried about that. I go surfing, hiking and do a bunch of stuff around the ocean and am trying to find a camera that would be durable in SALT water as well as fresh water lakes etc.

I had a Rollei X-8 Sports camera, but I took it surfing with my friends today and water came through the lens and the battery case (even though it was completely shut and secure, and I cleaned the battery container area before going in). Basically the camera sucked, and it was from an unreputable company.

I am trying to find a camera that I can take with me hiking, mountain biking, snowboarding, surfing, etc. that will last.

I also want it to have decent image quality with (hopefully) IS because I can't really be stable when I'm mid-incline and see an awesome view of something and want to snap it.

I'm trying to put everything up on a portfolio as well, and am getting semi into art and want to keep a decent looking portfolio ... hopefully going in to travel blogging. (That's another story too!)

Any suggestions?!
