I've always wanted to give it a shot! I never really got the chance to be part of a course! I'm very fascinated by what lurks below and what kind of creatures I might see under water :)
I think the project you were part of is great - that way you can do what you love and take care of the environment the same time! There should definitely be more similar projects out there. Next time I get the chance I'll try and do it for sure!
