One AT/TA pair for 0, CG/GC for 1.
Chop into suitably sized chains with primers indicating directory structure.

Advantages - Can be easily read and replicated and stored either in vitro (cryo) on in vivo via inserts.
Disadvantages - Time consuming to run searches, writing new data involves multiple single-point mutations.

Then you have such fun things like Open Source dive computers, deco planning software such as V-planner and some maths & physics involved in gas mix calculations, partial pressures and surface-air-consumption rates.

The technology side of diving is amazing. OLED touch-screen computers, integrated HUD masks, wireless gauges, closed-circuit rebreathers, underwater electric vehicles and all sorts of cool gadgetry. If you still want more, there's also underwater photography and video gear.

It's really an ideal sport for geeks. There's not much physical activity needed, a massive amount of shiny tech toys to play with and you don't need to bother with pointless small-talk underwater.

Unless you're trained by an agency that includes deeper and more adventurous diving. BSAC, for example, will certify experienced divers down to 55m on air. Decompression stops are introduced (although briefly) to entry-level divers and deco planning is an essential part of training.

To put the depth in context, one of most popular wrecks, the SS President Coolidge sits at about 70m but there are dives available for all abilities. 45m seems about right for a wreck of this size and I look forward to diving it in a few years time.

There is a massive environmental downside to this. The exhaust fumes will smell of frying bacon and as a result, city centers will be awash with drool.

Rims are for posers... Get the spokes.

That should be space program. Terribly sorry.

Because it's polite.
An uncivil space wouldn't get much in the way of positive press.
