Great Hammerhead Sharks of South Bimini

Like a fashion model up on the catwalk, great hammerhead sharks sashay into one’s field of vision, and, if they were human, you would probably say they have just “made an entrance”. Their strange mallet-like head, robust body girth and tall sickle-shaped dorsal fin make them well-nigh instantly recognisable, and most other sharks in the immediate area spot that too and give them a wide berth.

Peak season for the SEABOB

Whether as enjoyment at the beach or adventuresome change on a yacht – the Seabob offers plenty of fun in the water.

Suunto Wireless Tank Pressure Transmitters

Suunto Product Recall

The Finnish manufacturer has identified a potential safety risk affecting all Suunto Wireless Tank Pressure Transmitters and Suunto Tank PODs that wirelessly transmit cylinder pressure to compatible Suunto dive computers.

In two reported incidents the exterior case of a Suunto Wireless Tank Pressure Transmitter has failed during regular dry land pressure testing. Although extremely rare, there is the potential for injury because of the risk of bursting.

Three-dimensional models of the American alligator's skull were developed using cutting-edge imaging and computational tools.

3-D models of alligator skull developed

Studying the origins and movement of animals often requires the presence of live animals. However, this is not always possible (in the case of extinct species), safe or practical. In such cases, scientists now have another option: developing three-dimensional models of the animal.

This is what the researchers at the University of Missouri (MU) and the University of Southern Indiana have done. Using cutting-edge imaging and computational tools, they have developed three-dimensional models of the skull of the American alligator.

Aircraft Wrecks of Papua New Guinea

World War II came to the Australian territory of Papua New Guinea in January 1942 when the Imperial Japanese Army invaded Rabaul in New Britain, followed shortly after by the taking of Kavieng in New Ireland. The invasion turned Papua New Guinea into a major theatre of war in the battle for the Pacific, and there were many brutal encounters between the invading Japanese and the defending Allied forces.

DDRC launches diving ear survey

Ear health problems are one of the most commonly reported issues by divers. Problems can range from a relatively simple condition, for example, “swimmers ear,” to a more serious condition such as barotrauma, which can result in lasting damage to the ear.

Currently, anonymous field data is sparse, therefore Devon-based DDRC is hoping to find out what type of ear problems are most frequently encountered whilst diving if any medical advice was obtained; and if not, what was the outcome.

Prince Philip, Champion of British Scuba Diving, To Retire From Public Life

As a younger man Prince Philip was a keen sports enthusiast and an accomplished sailor.

In 1939, Philip Mountbatten joined the Royal Navy, graduating from the Royal Naval College, Dartmouth, in 1940 as "the best cadet in his course". His prize? A £20 book token. He subsequently saw active service in the Indian Ocean and the Mediterranean during WWII. In 1941 Philip Mountbatten was mentioned in despatches for his service on the battleship HMS Valiant. And he was in Tokyo Bay in 1945 when the Japanese surrendered.

Contextual advertising

The web banner on the immediate left is a mock-up example of an advertisement placed in a specific context; In this case this very article. If say, this post was about diving masks, the advert could be for a brand of diving masks. Or if the subject matter was a about a location the ad could be from local dive operators. The banner shown on the left is a 160 x 600 pixels 'wide skyscraper' skyscraper.

What exactly is meant by "Rebreather Friendly"?

“Rebreather Friendly” dive centres—what exactly does this mean? With emerging technologies becoming more mainstream in the diving world these days, more and more people are making investments in rebreathers. Everyone knows the advantages of these pieces of kit—extended dive time capabilities, reduced gas usage, quieter and less obtrusive to the aquatic world, etc. But are dive operators thinking along the same lines?
