The recreational dive computer has allowed divers to extend their diving as well as giving a better means to prevent DCI.   The development and publishing of the recreational dive tables was one of the first steps that increased the safety of divers. These tables were a modification of the tables that the U.S. Navy had developed for their divers. For the recreational diver, the Navy tables had some fundamental even fatal flaws. Navy divers normally worked at one depth, they descend, do the job and return to the surface. The No-Decompression Limits (NDL) were easy to follow for them. Recreational diver are more likely to spend time at different depths while diving. So following the NDL left the potential of unused diving time. On the other side of the coin, the Navy tables accepted a higher degree of risk than a recreational diver could be expected to accept. Navy divers would follow the same tables in times of war, were mission requirements were higher. The Navy divers also h...

A second-stage free flow regulator happens when the downstream valve in the second stage sticks wide open. Most of us have experienced that at one time or other at the surface. You place your regulator in the water at the surface with its mouthpiece face-up, and the next thing you know, your reg is wildly free-flowing. Usually, all you have to do is put your thumb or hand over the mouthpiece or turn the reg face-down, submerged in the water. At the surface, a free-flowing regulator is annoying, but at depth, a regulator locked in free-flow can be dangerous. Cold water is the No. 1 culprit behind a free-flowing regulator, but there are less-common reasons, too. For example, there have been instances of a diver using their octopus reg to inflate an SMB, only to have it free-flow. A second stage that is clogged with sand, jamming the valve open. Suddenly, you’re immersed in more bubbles than those produced by a Jacuzzi. So what should you do if your regulator free flows at depth? Yo...

Jellyfish get their common name from the gelatinous material, called mesoglea, that makes up most of their bodies. This substance consists primarily of water and includes muscle, structural proteins and nerve cells. Jellies also have an external epidermis containing a loose nerve network (the most basic nervous system of any multicellular animal), an internal layer of cells and a single opening to ingest food and exchange reproductive cells. Jellyfish may have painful stings, but they also have more fascinating and impressive characteristics. From their multiple-stage life cycles to their long history across the breadth and depth of the world’s seas, jellyfish may have something to tell us about the changing health of their waters. Defining Jellyfish Fried egg jellyfish ( Phacellophora camtschatica ) with stinging tentacles extended There is some disagreement within the scientific community about the true definition of jellyfish. Out of the 10,000 species in the phylum Cni...

9 facts about Greenland sharks The Greenland shark, or  Somniosus microcephalus,  is one of many marine mammals that live in the waters around Greenland, though this is not the only area in which the shark dwells. These sharks, which are sometimes referred to as “gray sharks” or “gurry sharks,” can also be found in the north Atlantic Ocean near Iceland, Norway, and Canada. 1. Greenland sharks are really, really big  If you are looking for a Greenland shark, it is important to have a good understanding of their physical dimensions. Greenland sharks are among the largest sharks in the world, comparable in size to great whites. They have been known to grow as long as 6.4 meters (21 feet) and as heavy as 1,000 kg (2,100 pounds), though the typical Greenland shark weighs around 400 kg (880 pounds) and is about 2.44 to 4.8 meters long (18 to 15.7 feet). 2. The meat of a Greenland shark is poisonous Greenland...

Plastic Oceanic was founded with a simple premise to clean up and try to find a use for the unrecycleable plastic waste found and collected from the coast around Cornwall. The company now creates beautiful gifts and jewellery made from the collected unrecycleable ocean plastic. Founder, Dan Edwards who has been a surfer and deep sea diver for many years had seen first hand the plastic polluting our coastal areas and decided to start cleaning it up. After recycling the appropriate materials, a mountain of unrecyleable plastic waste would be left and it was decided that a use for it must be found in order to avoid it just going back to landfill or for incineration. Plastic is now collected from all over the coastline in Cornwall and Plastic Oceanic has invested heavily in equipment allowing this plastic waste to be made into jewellery and other products. Presently the company sends all appropriate materials to be recycled and will also be sending hard plastics like HDPE to other or...

Asking a Scuba Diver about diving will get you a response similar to asking a grandmother about her grandchildren. The answer could go on for hours. Unlike the grandmother, however, the diver’s stories are very likely to be exciting and you may start to envy their experiences. While the grandmother’s stories will only interest a few, the diver’s stories will have a more universal appeal. The stories may tell of their first encounter with a favorite species, or the beauty of a coral reef day and night. They may try to explain to you the feeling of weightlessness or the sense of well being watching the life on a reef. Your dreams will recall the ship wrecks he described or the turtles she told you swam alongside her. Their stories may open up new horizons for you to first consider and later explore yourself. Scuba Diving is an activity like no other. In the early days of scuba diving, the early 1950s, scuba was always capitalized as SCUBA, an acronym for Self Contained Underwater Bre...
