Hi Talia,
I’m "Airworks", and have been a certified diver since the age of 14. I am very much at home in both salt and freshwater environments. Most of my diving experience has been along the east coast of the U.S. (Florida, North and South Carolina, Virginia) and the Caribbean (Puerto Rico, Bahamas).
Your second paragraph caught my eye, so I’d like to draw your attention to two articles I’ve written for Divebuddy. These can be found in the Educational tab under "Articles".
As you’ll see, I am particularly concerned about the negative impact under-informed (in regards to marine bio-systems and synergies) and naive scuba divers are having on our beautiful and life-essential oceans.
The articles are titled "Empirical Research Has Confirmed the Therapeutic Benefits of Scuba Diving" and "A Shocking and Embarrassing Discovery".
Please feel free to use any material from them for your project.
I really don’t think an interview is necessary since those two articles cover much of what I think our conversation would revolve around.
In any case, let me know if you have questions or would like to follow up on something I wrote about.
Good luck on your project and website.
