Main features in this issue include:
In the last issue we looked at the advantages and disadvantages of digital underwater photography compared to traditional film systems. Now we’re going to look at what kind cameras and housings are available on the market today, the costs involved, and which one is right for you.
Compact Cameras and Housings:
Many millions of years ago, a piece of a land broke away from the ancient continent, Gondwanaland, from the place we now know as Morocco, and traveled a long journey westward until it collided with the North American continent a bit to the south of Greenland. The first Europeans who visited this new world in 986 A.D. were the Icelandic Vikings under the command of Thorfinn Karlsefni, but the newcomers did not settle the area for a long time.
Newfoundland is the biggest of the Atlantic Canadian provinces, the mother land for hundreds of thousands of caribou, millions of birds, the famous breed of black diving dogs and moose, which can be found walking on motorways.
During our initial open water training, we were all shown how to use a dive table. But did we ever use it again - and is the right tool?
Few instructors, however, remember to mention at this point that dive computers or bottom timers can do all this, easier faster and safer. And in reality, on the next adventure into the abyss, most will be indeed be equipped with a computer and/or be supervised and led by a dive master anyway.
Named Time magazine’s first “hero for the planet” in 1998, marine biologist Sylvia Earle has pioneered research on marine ecosystems. She has led more than 50 expeditions—that’s more than 6,000 hours underwater. Earle has been an explorer-in-residence at the National Geographic Society since 1998. She holds many diving records, including the women’s depth record for solo diving at a thousand meters (3,300 feet).
It was the attitude. The complacency is what prompted me to visit Australia a few years ago when a reporter put the question to me, ”Why should I care about the ocean?” She said, ”I don’t swim. I get seasick. I don’t fish. People don’t drink salt water.
When we think of the animals of the oceans our first thoughts are generally of whales, sharks, dolphins, tuna fish, and perhaps octopusses. All these have been in the news lately, also in this magazine, for reasons regarding their behaviour or exploitation. These are large animals, and like the lesser food fishes such as salmon and herring, we have many reasons for our interest in them.
There is one important common factor in the examples of marine life given above. They all have their prime existence in the water, i.e. at least partially below the surface.
Raja Ampat in Indonesia is dotted with tiny islands scattered like beads across an area of sea and surrounded by large platform and fringing reef systems.
Areas of mushroom shaped rock islands seem to harbour some of the better dive sites and make for beautiful and interesting topside scenery as well. This area is destined to become a World Heritage Site.
