Scuba Diving | February 2016 cover

This month’s issue has an underlying theme of exploration – but really, doesn’t everything dive related? The very nature of the sport is to seek out worlds oft-overlooked by land lovers. In the February issue, we jump into the waters of national sanctuaries, where thousands of shipwrecks lie uncharted. Then we whisk you away to the future, where divers are exploring the depths of other worlds, with a whole lot of ground covered in between. As is the case every month, Dive Training Magazine can be picked up at your local dive store, found on most newsstands, or accessed on your smart device. Remember, a good diver is always learning!

Here’s a look at what you’ll find between the covers of the February 2016 issue.


Public and Private Partnership: NOAA and Volunteer Divers Explore America’s Historic Shipwrecks
By James P. Delgado
The waters of the United States, both off the coasts and in the Great Lakes, are home to 13 national marine sanctuaries, a national marine monument, and a single historic shipwreck. These various sites fall under the jurisdiction of the National Oceanic and Atmospheric Administration Office of National Marine Sanctuaries. This article overviews a host of volunteer programs happening within the sanctuaries, including coral reef monitoring, marine life assessments, lionfish roundups, beach cleanups, mooring buoy maintenance, and discovering, mapping and documenting shipwrecks.

The Underwater Heart: A Diver’s Guide to Cardiovascular Health
By Alex Brylske
It’s been said that divers are a different breed, in that our sport offers unique challenges unlike those of many leisure activities. It turns out that scuba diving — immersion and breathing compressed air — presents challenges to divers’ cardiovascular systems. In this article, the author provides an overview of how the underwater heart operates, and explains why maintaining good cardiovascular fitness is paramount to safe diving.

Outer Depths: Exploring Oceans of Other Worlds
By Robert N. Rossier
Deep-sea exploration has been a challenge here on planet Earth. Crushing pressures and low temperatures test our design capabilities, and building craft to survive and explore the depths has taken every bit of engineering ingenuity we can muster. So imagine what it would take to send a submarine to the depths of the sea on a distant moon of a faraway planet. That’s exactly what engineers at NASA are planning to do by 2040 (just 25 years from now). And the challenges they face are utterly out of this world.

The backroll entry is a necessity when diving from a small inflatable boat, “panga” or skiff, but entering the water backward can seem a bit daunting at first. This month’s Scuba Skills column, “Entering From a Small Boat: The Backroll,” reminds us that the goal isn’t to somersault or flip into the water, but simply roll off the boat.
