A phone call is all that it takes
We have reported on the plight of the sea turtles before. We have reported how they were being butchered by the thousands. And we have asked for your support and signatures on a petition to stop the slaughter of these ancient ocean citizens.
It is now time to report back that your support has made a real difference. But the fight is not quite over yet...
Lyngstøls vattnet - Norway
The Norang valley is clothed in pale green birch leaves and sprouting grass, and the mountains rise majestically up in to the clouds. The mountain tops are completely snow covered, and at the foot of the mountains are large masses of stone from both new and older landslides. A small red car with four divers drives slowly down the valley stopping excitedly at each small lake to check the visibility and condition on the bottom.
As early as the 1880s the Norang valley was a popular tourist magnet among the European aristocracy and upper classes, authors and mountaineers. The expeditions of the latter often had the aim of being the first to climb the surrounding mountains.
Nitrogen narcosis, or “rapture of the deep,” is one of those things that some divers like to joke about but really is no laughing matter. (Pun intended) While a recreational diver is far more likely to experience nitrogen narcosis than decompression illness, we know much less about the exact physiological mechanism of nitrogen narcosis than that of DCI.
So, when we were on Bonaire a few years ago on Father’s Day and my daughter, Stacy, gave me a T-shirt that read, “I’ve got nitrogen narcosis. What’s your excuse?” I was not quite sure how to take the message. I assumed it might have been a critique of my fanatical diving.
We have written much here in this magazine about the different properties of water. Some of them, such as surface tension, are of importance to the ability of aquatic fauna to function in their given environment. For example, surface tension permits water skaters to skate on the surface of the water where its habitat is neither the water below the surface nor the air above.
Rescuing a Rebreather Diver

White nights at the White Sea
Russia. I am here. I am gripped by a sense of disbelief. As the tundra flies past the train window recollections of grainy tv-images from my childhood keep popping up. The marching soldiers and missile batteries being paraded across the red square before the pouty looking Leonid Breshnev and the politbureau looking on from the top of Lenin’s mausoleum. That was scary days.
Working with Models
Incredible as it may sound, one of the most difficult creatures to shoot under water is a human being. That is, if your goal is to integrate a diver in the underwater environment as a natural, harmonious element. Let’s look at some of the more important factors in achieving a great diver portrait.
