Three amateur divers trying to free snagged lobster pots have discovered the well-preserved remains of what is thought to be 17th century warship Resolution.

California`s Scubapro said Wednesday it was recalling 670 of its X650 second-stage regulators.
A manufacturing error could cause the main housing of some regulators, which divers place in their mouths to breathe, to change shape over time, which could cause the cover and diaphragm to become dislodged, Scubapro said. If this occurs, airflow will be interrupted and the regulators will no longer function, posing a drowning hazard to users.

When it comes to sharks, researchers say Hawaii waters are teeming with tiger sharks. In 10 years of diving the South Pacific, film maker and free diver Kyle Nakamoto has had many close encounters with sharks, tigers included. He knows the warning signs.
A massive, hooked and tied female tiger shark attacked an inflatable boat Saturday during shark-tagging operations off this remote reef.
No one was injured, and the rigid-hulled inflatable was damaged but not disabled.

A team of fearless Northland divers has smashed the world record in a gruelling underwater sport: Extreme Ironing.
Many a grown man has been known to run screaming from an ironing board even under ordinary circumstances, but last Friday a record 55 athletes braved creases, synthetic shirts and shonky boards - under 30m of water.
Calvin Tang recently went diving with a newly-certified diver. Upon returning, they placed their gear in a freshwater rinse. Unfortunately, Calvin’s friend forgot to replace the dust cap in the first stage. Of course, we’ve been told a gazillion times not to get water inside the first stage, so naturally Calvin freaked when he discovered the first stage had flooded. After searching for information on how to handle the situation (to no avail), he called his local dive shop; the staff member assured Calvin that the problem was minor, especially since the first stage had flooded with freshwater. (Even if it had flooded with saltwater, however, the problem is simple to correct, but first you need to rinse the unit thoroughly with freshwater to avoid corrosion.) Ultimately, it was easy for Calvin to dry out his first stage.

Since the days of Aristotle, humans have looked to dolphins with awe, envy and inspiration because of the marine animal’s speed and strength in the oceans. Swimming at speeds of up to 20 mph, the dolphin seems to defy nature’s laws. In fact, in the 1930s, the scientist James Gray thought that the power needed for the dolphin to swim at such speeds exceeded its available power nearly 10 times over, which is known as Gray’s paradox.
To explain his paradox, Gray theorized that the water against the dolphin’s skin has layers that slide past each other and reduce drag, called “laminar boundary layers.” (It was previously assumed that the water against the skin was made of several mixed layers that increase drag, called “turbulent boundary layers.”) In actuality, no mechanisms have been demonstrated that maintain a completely laminar boundary layer for the dolphin.
HOLLYWOOD cutie Jessica Alba is so hot, she even gets dolphins horny when she goes scuba diving.
The actress discovered the cetacean mammals got aroused by her presence when she was shooting dolphin drama Flipper.
She told MTV: “I don’t know if anybody knows this but dolphins get excited, even when you are a human being - and they have long, long… (penises).
It’s getting so you can swim with sharks in virtually every aquarium - or so it seems. Bangkok’s new aquarium came complete with a swimming with sharks feature, which I mentioned a few months ago - and now Kuala Lumpur’s Aquaria is offering you the chance to get up close and personal with our toothsome friends. There is a article from the Malaysia Star newspaper that describes a non-diving journalist’s experience of trying to dive in the shark aquarium tank - unfortunately he couldn’t get below the surface as he kept panicking. Oh well, at least he got to see the sharks from above if nothing else.
John Bantin of Divernet put together an interesting and amusing list of 99 reasons to dive the Maldives this year….as if you even needed one reason. Nevertheless, the list include such things as the British Loyalty, Gilis, Mushimashma, Oriental Sweetlips, Hukuruelhi Kandhu, finolhus, and many, many more intriguing attractions. If you don’t know what these words mean, then you definitely need to check out the piece.
