    Corals
      |  
    The exploitation of corals has depleted stocks all over the world. This is not only destroying the seafloor, but has a much wider impact. Corals are more valueable if they stay in the oceans rather than around someone’s neck. Coral reefs support more than 25 percent of all known marine fish species. As one of the most complex ecosystems on the planet, coral reefs are home to more than 4,000 different species of fish, and almost 5,000 species of corals, in addition to thousands of other plants and animals. Scientists estimate that coral reefs provide an economic benefit of US$ 375 billion each year to millions of people around the world. Besides from indirectly feeding people, corals also offer cures for illnesses. Add to that that coral reefs protect our coastlines.

    On August 2, 2007, the weather was good at the North Pole. The sea was calm, the water temperature was just -1° C, with the air at a balmy 0° C. That morning two Russian mini submarines, Bathyscaphe Mir-1 and Mir-2, were sent down and at noon, Mir-1 touched down on the seabed at 4,261m, planting the Russian flag

    Freediving
    Just their name, their size, and their menacing looks can evoke feelings of terror, fear and instinctive rejection. However, if you have the privilege to be able to dive with big tiger sharks, as I have, you might fall in love with them, at least you will bond with them in a mysterious way. They are certainly not as “cute” as marine mammals or nthropomorphized clown fish, but they will have an impact on you that could change your perception of sharks, and marine life, forever.

    Two of the resident orca families from Puget sound —L and K pods—have been seen in recent years feeding off the California coast in the winter. That was unheard of before early this decade, leading scientists to speculate they are driven to swim hundreds of miles just to meet their minimum nutritional

    Do divers really need underwater lamps? It is a simple question to which there is no simple answer, as it all depends... If you are mostly diving in Southeast Asia or the Caribbean where visibility is fantastic, during days of bright sunshine and in waters of 20m or less, you probably don’t need one. But if you plan on diving in lakes, doing night dives, penetrating wrecks or do any sort of technical dive, then a good lamp becomes an essential part of your diving gear

    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. Unfortunately, both can result in a diver fatality, the first from being bubbly drunk and foolish and the second from being bubbled up.

    Water properties
      |  
    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.

    Why the peculiar head shape of the hammerhead shark developed as it did has been the subject of much speculation. Few other morphological oddities have inspired so many fanciful and sensible theories about its function as the weirdly shaped head that characterises the hammerhead shark. Recent experimental evidence supports some ideas and refutes others, while pointing to a previously unsuspected role for this peculiar feature.

    The use of rebreathers in caves is nothing new. Decades ago, Hans and Lotte Hass used them to venture into marine caves. Profiles like Rob Palmer in the UK, Bill Stone, George Irvine and Jarrod Jablonski in the USA, or Olivier Isler in Europe, are also strongly linked to rebreathers and cave diving.

    Something I find surprising in the 21st century is the amount of divers that have had no formal training below 40 meters, which chose to conduct dives regularly beyond this depth going to 50 or 60 meters on air and in some cases even deeper.
