HMHS Britannic was the largest ship to sink during World War I. (Weighting in at almost 50,000-tons she was also the largest ship in the world).
Many argue she is one of the most beautiful, intact, well-preserved passenger liners accessible to divers. It is little wonder that these factors, and the story behind her construction and sinking continue to capture divers imagination.
This video shows a different type of agonistic behaviour, found in the blacktip reef shark. It was created to go with the article entitled Posturing Sharks, published in X-Ray Magazine #76
This sounds simple enough, but not when one considers that the reef - the third largest coral reef in the world - measures nearly 150 miles long and four miles wide. The question of where to place the new corals comes into play.
Enter biology professor Robert van Woesik, from Florida Institute of Technology.
Armed with a US$205,000 grant from the Florida Fish and Wildlife Commission, he and his team are working to identify the habitats and localities in the reef tract that offer optimal conditions for coral survival.
The Queen Victoria Museum and Art Gallery in Launceston, Tasmania has achieved scientific results of interest to beer brewers and drinkers worldwide.
The museum has identified what is believed to be the world's oldest beer, surviving as contents of a bottle salvaged from the protected Historic Shipwreck Sydney Cove (1797) at Preservation Island, Tasmania.
While many sharks are solitary predators, some are known to live in groups and are suspected of engaging in complex social behaviors. Meanwhile others simply aggregate due to similar habitat, food, or mating requirements.
Using a novel tagging procedure, scientists in the United States, have discovered that some shark species like to spend their time mixing and chilling out together.
"Setting such a demanding world record begins with an idea. To realize it, you need a highly motivated team. I would like to thank everyone who supported me in this challenge", said the extreme athlete right after setting the world record on September 27, 2016.
At a diving depth of up to 10 meters, Wolfgang Kulow traversed the 20 km (12.5 mile) distance from the Danish island of Lolland to the German island Fehmarn in only four hours and nine minutes, setting the world record for the "fastest underwater crossing of the Fehmarn Belt".
The objective of the program is to build confidence, independence and self-esteem in the lives of children, adults and veterans with disabilities through the sport of scuba diving, scuba therapy and related activities.
The purpose of the program is to provide and support educational scuba diving programs with PADI courses—such as the PADI Seal Team, PADI Junior Open Water and the Open Water Diver course—that are open to any child, adult or veteran with a disability, with the hope of providing both physical and psychological therapeutic value to that person.
There are many advantages to diving closed circuit for the underwater image creator such as better interaction with wildlife or longer dives. However, there are also a number of disadvantages to consider such as added complexity and task loading.
On September 27, 2016, extreme athlete Wolfgang Kulov plans to cover a distance of 20 kilometres.
He will start at the Danish island of Lolland and end at the German island of Fehmarn, with a maximum depth of 10 meters.
Rising out of the depths, a shape emerges from the shadows, methodically swimming in a wide arc. The outline is unmistakable, as it continues to climb and inch closer at every turn. With one last pass, seemingly in slow motion, I am struck by the sheer enormity of the creature in front of me.
The goal is to help preserve the state's shipwrecks by giving divers another option besides hooking a line directly onto the wreck, as is customary now.
"Putting a mooring buoy on a shipwreck is absolutely, hands-down, the best form of physical protection you can do for a wreck," Wayne Lusardi, a state maritime archaeologist at the Thunder Bay National Marine Sanctuary in Alpena, told Mlive.com
The meeting was first proposed by the National Park Service (NPS), then quickly supported by National Oceanic and Atmospheric Administration (NOAA), Divers Alert Network (DAN), and the American Academy of Underwater Sciences (AAUS).
A number of key experts were involved in the Catalina Island event including Jeff Bozanic, Simon Mitchell and Richard Pyle.
Over the course of four days standards relating to practice, physiology, incidents and equipment evolution relevant to scientific diving with rebreathers were reviewed.
