FEATURES

The Building Blocks of Reefs: How Corals Do What They Do
By Karen and Ian Stewart
The more we learn about how the corals operate, the more we grow to appreciate our time spent underwater. In this article, the authors take a look at how corals serve as the building blocks for the marvelous marine ecosystem we call the coral reef.

Health for Diving: A Primer on Diabetes
By Robert N. Rossier
On a global scale, diabetes afflicts more than 380 million people and the World Health Organization estimates that by 2030, the number of people living with diabetes will more than double. Clearly, diabetes is a growing health risk and one that could affect our ability to dive safely. But at least for some afflicted with the disorder, the door has been opened for scuba diving – that is, if the proper conditions are met and the proper protocols are followed.

By Barry Guimbellot and Marty Snyderman
Steady progress in LED technology has resulted in making LEDs a potentially viable alternative to strobes in underwater photography as well. To borrow the words of legendary songwriter and singer Bob Dylan, “The times, they are a changing.” At least, they are for some and, if you are an underwater photographer, this article will give you an overview of LEDs as a lighting option.

The Covers

Corals are the kings of the reef. In this month’s cover feature, “The Building Blocks of Reefs: How Corals Do What They Do,” we learn how these tiny polyps have developed a kaleidoscope of color, diversity of shape and size and also contributes to the building of these reefs.
