I first learned about this unusual lake, nestled in Marble Canyon Provincial Park of British Columbia (BC), Canada, when some friends living in Kamloops asked me to join them for a dive at a local, clear freshwater lake. Since it was only a few hours from Vancouver, I decided to take them up on their offer and headed for the interior parts of BC.

I have always wanted to explore this area and was thrilled even more when they told me of the strange coral-type of life living in the lake.

The Perfect Diving Breath

Confronted by a genie in a lamp and three wishes, many new divers would ask for a magic spell to make their air last longer on a dive. The good news is that you don’t actually need a genie in a lamp—the key to better air consumption is not a secret at all.

Divers usually find that their breathing rate drops as they become more experienced, simply as a consequence of their becoming more relaxed and comfortable in the water.

Talent plus personality. That’s how clients and colleagues explain 35-year-old Becky Kagan Schott’s rapid ascent in the male-dominated, niche-filled world of underwater cinematography. “There are only a handful of people you can call if you need someone to dive to 350 feet, shoot and be creative,” explains Evan Kovacs, director of underwater photography at Woods Hole Oceanographic Institute’s Advanced Imaging and Visualization Lab.

Colleague, British underwater cameraman Rich Stevenson said that her skilled and energetic “let’s do this” attitude is the icing on the cake.

Golfe-Juan on the French Riviera

If you are in Europe and like the idea of a short flight to Southern France and diving on the same day you arrive in the Mediterranean, then perhaps you may want to try the seaside resort town of Golfe-Juan—just a short ride west from Nice. Average journey time to Nice for flights from all over Europe is only two hours. My wife, Lesley, and I chose to fly EasyJet from Edinburgh.

One small side street away from the old port in Golfe-Juan is Diamond Diving.

The Great Hammerhead Shark

First described in 1837 by the German naturalist  Eduard Rüppell, the great hammerhead shark (Sphyrna mokarran) is the largest of the hammerhead shark family and can reach a length of over 6m (20ft), although some specimens have been seen to be much larger than this. However, with overfishing, the great hammerhead is usually observed to be much smaller than this.

The curious shape of the hammerhead shark has aroused much speculation over the years and it is now widely recognized that the shape of the wide hammerhead shape (called the cephalofoil), has adapted over the millions of years to be aid-specific to their main prey—stingrays, eagle rays and other

Great Lakes: A Haven for Wreck Divers

There are other areas of the world with well-preserved shipwrecks, but the Great Lakes has the monopoly on sheer mass, variety and relative ease of access. Very few known dive-able wrecks are much more than a few hours boat ride from a decent restaurant, a chain hotel or a decent-sized town. Isle Royale, in Lake Superior, is a notable exception, but most wreck dive sites in the Great Lakes do not demand an expedition set up to reach.

I had lived in North America for a few years before I gave the Great Lakes much thought.

Florida Manatees: Sirenians of Crystal River

A winter’s dawn is a special time to be on Kings Bay, for as the first rays of the Florida sun appear over the horizon, they light up the soft mist on the warm waters of the bay and create an ethereal, almost mystical, feeling. Listen carefully and you will hear the gentle ripples from the swirl pools formed by the paddle-like tails of the sirenians, as they make their way towards the freshwater springs that are the source of Crystal River.

The arrival of the manatees usually coincides with a rising tide and heralds their return from feeding on the sea grass of Kings Bay and Crystal River.

Tonga's Humpback Whales

Our skipper, Ali, carefully maneuvered the boat into position and cut the engine, shouting, “Go, go, go!” at the top of his lungs. And go we did—straight into the deep blue water, with cameras held in vice-like death-grips and onto the path of over a dozen mature and rather excited humpback whales.

Humpback whales average around 14m long and about 35 tons in weight―that’s a lot of mass coming at you―but there was no time to feel scared or even count these huge submarine-like mammals, because we were finally witnessing one of their famed heat runs, when a female humpback has signaled

The CEO of Poseidon discusses his move from the automotive industry to diving, big data, the role of automation, safety and the future of rebreather diving.

"I want to give divers the time to think before they act, based on the huge task load under water. But primarily it is the underwater experience that is the key for future innovation."

Cold Water Photography

Perhaps one of the most difficult, but also most rewarding aspects of all underwater photography is to be able to photograph an animal, or fish, in this instance, in its preferred habitat, without inducing any undue stress or obvious invasion of the creature’s life space.

Firstly, it is much better to stay well clear of the subject and its habitat, approach the subject slowly and sympathetically, and at least this way you are able to keep off the seabed or wall without causing any unnecessary damage.
