Remember the first rule of scuba diving that you were taught in your basic open-water class? I believe it goes something like: “Keep breathing!” Simple advice and unarguably the best advice possible for any diver, not just those entering the sport for the first time.

For example, the same first rule is true for technical diving. Gas management 101 starts off by stating something like: “Always have a sufficient volume of appropriate gas to breathe throughout the whole dive!”

Healthy shoulders are vital to a positive scuba diving experience.

The mobility of the shoulder joint exceeds every other joint in the human body. It enables divers to reach behind, under, around, above and beyond in nearly unlimited directions and rotation. Consequently, by design the shoulder joint and its musculature are highly susceptible to injury all of the time and especially during scuba diving activities.

The ball and socket joint of the shoulder, unlike the hip joint, is more like a cup and saucer as the ball of the upper arm bone (humerus) is larger than the socket (glenoid) of the shoulder.

Incredibly rich waters

Arus kencang are the words you need to listen out for—you will hear them in the rapid interchange between the dive guides and the boat boys, as they discuss the practicalities of safely immersing a group of “bule” (slang for foreigners) in the waters of Raja Ampat.

The incredible reefs and tremendous biodiversity of the Raja Ampat area have made this remote part of the Indonesian archipelago one of the hottest dive locations in the world, and those currents are the very lifeblood of the area.

American artist, Lauren Kussro, has been inspired by the sea to create work that is extraordinary, unique and meticulous, capturing in printmaking and printstallations the intricate beauty and poetry of marine creatures and underwater life forms, which divers know and love so well. X-RAY MAG interviewed the artist to find out more about her mesmerizing work and artistic vision.

"I think one of the reasons I like ocean life is that it looks really familiar to us but also extremely alien in a way. Coral is so similar to above water plant forms, but is so bizarre and weird at times! I love that."
-- Lauren Kussro
