 Snorkeling often is viewed as a more casual method of exploring the underwater world. More so than scuba diving, anyway. It requires no certification and no more than a mask, fins and snorkel. But it does require something that often gets little consideration: respect for your surroundings. In this month's cover feature, "Take Only Memories, Leave Only Bubbles: A Guide to Responsible Snorkeling," author Alex Brylske explains the small things snorkelers can do to make a big difference.

Take Only Memories, Leave Only Bubbles:
A Guide to Responsible Snorkeling
One challenge in dealing with snorkelers is that it's not easy to get the word out to them on why and how to act responsibly when visiting coral reefs. Because scuba diving requires training and certification, there's an easy mechanism to educate all of us bubble-blowers. Not so with most snorkelers. Thus, it's hardly surprising to witness the flailing, uncontrolled kicking and - when all else fails - standing on the reef that is common among our tankless brethren. The author describes how we can help snorkelers become reef-savvy.

Trees of Life: Mangroves Act as Nurseries and Filters for Life on the Reef
For the most part, "mangrove" refers as much to an ecosystem as to a type of tree. Mangroves have their work cut out for them. They have water to filter, and diverse marine life to sustain. The author offers an important botany lesson that explains why mangrove ecosystems are important to coral reefs.

Where Diving Makes a Difference:
The Demanding Role of Public Safety Diving
Rather than choosing the time and place of their dives, and picking conditions that are favorable, public safety divers go where and when they are needed. And while what they do may be challenging and exciting, it usually isn't exactly fun, and it is always work. Whether looking for crime scene evidence, searching for a missing person, or performing some form of security-related task, the fact that public safety divers are willing to go the distance is what matters.
