    The way an animal gets around in the sea and or in the air depends, fundamentally, on the density and viscosity of its milieu. Birds use the low density and viscosity of the atmosphere to fly or glide, with the range of their movement being limited only by their endurance and the height to which they can fly. This is similar to the fishes and similar marine creatures who can also move three-dimensionally within their aqueous milieu though unlike the terrestrial creatures which live on the, essentially, two dimensional surface of the earth. The latter have evolved locomotive mechanisms which are suited to movement dominated by gravity. In the case of humans, for example, a two-legged mode of locomotion suited to this situation has evolved. To a certain extent, birds may seem to be independent of gravity as they fly around in the air. However, unlike marine creatures in their aqueous milieu, if they stop flying they immediately crash to the ground – unless, of course, they can glide for a little while.

    Many, many divers, underwater photographers and filmmakers, when asked about the origin of their passion to go underwater, say that they were inspired by the films and books of Hans Hass. He must be a very remarkable person, interesting to listen to, not to mention, Dr Hass is the greatest celebrity in the diving world today. Is it possible to meet him, to talk?

    Global diving travel has become increasingly easy over the last decade or so, providing easy access to a growing number of tropical and exotic destinations. So, for many divers residing in cooler climates or new to the sport, it is tempting to look only towards these warm distant destinations and perhaps ignore the wealth of marine life on their own doorstep.

    I can’t help likening this island to a chromosome. It’s contorted shape not only looks like one, but also has its different features spread out along different points even when you zoom in. Our focal point is the northern region. On the western side of the tip, we find Bunaken national park with its majestic drop-offs, on the top of the area around Gangga Island, and on the eastern side, Lembeh, famous for its critter diving.

    If there is any hidden secret in the Mediterranean, it is the island of Vis. For many years, it was a forbidden and restricted military area. It was not until 1991, when the iron curtain finally came down, that it was opened up for tourism and diving. On Vis, small picturesque port towns and spectacular wrecks, drop-offs and caverns are waiting to be discovered by divers.

    In the world of technical diving, a direct ascent to the surface is not an option if you run into a problem or emergency. For this reason, technical divers are required to carry back-up systems to resolve problems associated with equipment malfunction during a dive. But what about the rest of us?

    Since the introduction of Scuba diving in the mid 1950s, one of the most hotly debated subjects in the world of technical diving is that regarding the best type of gear configuration. Over the years, many experienced divers, instructors, and training agencies, have all claimed that their method and style of kit configuration is the best.

    Mask clearing and deployment of the Surface Marker Buoy. What's the connection between these two unrelated skills, you may be excused for thinking. They are both giving many students problems during training, that's what. In both cases it's all about getting it right from the beginning.

    Regardless of the type of dive, shallow non-deco recreational dive or the 120 metre deep mix wreck dive in the Atlantic, correct weighting will increase the safety and comfort of any dive tenfold. However, it is often the case that not enough emphasis is put on correct weighting from the very beginning, i.e. at the Open Water course.

    Consider a windy place — I mean, very windy — so windy you must ask the wind about what you can do today. Consider the wind as “mobile” as the “Donna” of the opera. He changes his mood at any time with no warning. Mood, in terms of wind, is direction, force, temperature, humidity and all the weather changes that come with them. Now, put yourself in a flat place, a plateau, with no mountains or trees to protect you and where the wind surrounds you all the time. Stay there and wait. Take your time to look around. You begin to notice that the soil upon which you are standing is covered with marine fossils and guess rightly that this was the sea floor some millions of years ago.

    I selected Maui, Molokai and Lanai of the Hawaiian Island Archipelago for my escape. Not only is Maui Hawaii's second largest island, it is home to Mount Haleakala, the world's largest dormant volcano with an elevation of 10,020 feet (3054m). I could hardly wait to explore the underwater sites and indulge in some topside activities like kayaking, hiking and ...

    Like every grand tale of shipwreck and lost treasure, the story about the Polluce has it all. A paddlewheel steamboat shipwrecked in 1841, it is the centrepiece of a drama spanning more than one and a half centuries and has all the necessary ingredients: drama and tragedy, greed and crime, passion and politics. And it is still ongoing. Polluce is about to be excavated once more as this story goes to press.
