Underwater aircraft carrier

underwater-aircraft-carrier.gifA WHITE ensign was today being laid over the wreck of Portland submarine M2 to mark the 75th anniversary of the disaster.

Ministry of Defence personnel and recreational divers were visiting the vessel, which sank during exercises off Lyme Bay, for the commemoration today.

The diving operation is the highlight of a series of events planned by the Nautical Archaeology Society (NAS) this autumn.

The entire crew of 60 sailors and airmen died when the unique aeroplane-launching submarine sank in 1932.

It is believed the disaster happened because the vessel’s hangar doors were opened before it properly surfaced.  

(D’oh!)

Underwater wedding

Chinese couple getting married in a shark tunnel.  How appropriate.  The Ithaa Restaurant, Maldives, might be another good choice, if one didn’t want to risk getting wet at an outrigger wedding.

Cities in the Sea

citiesinthesea.jpg

A global system of these structures can easily accommodate many millions of people and relieve the land based population pressures. They can provide the inhabitants with information and serve as natural sea aquariums without artificially enclosing marine life.

Many of these cities may serve as oceanographic universities that maintain the ecological balance of marine systems. Other ocean cities will maintain sea farms that will cultivate many forms of marine life. They could also be used as a new resource for mining the relatively untapped resources of the oceans without disturbing its ecology. Still others may monitor and maintain environmental equilibrium and reclaim dangerous radioactive and other pollutant materials that have been dumped into the sea.

After construction, these structures can be towed to various locations where they would be most beneficial, then anchored to the ocean floor. Some structures will be towed in prefabricated segments and then joined together at selected locations. Their internal construction will include floatation chambers which will render them practically unsinkable. They can be self maintained and fully automated

The Ithaa Restaurant sits 15 feet below the waves of the Indian Ocean, surrounded by a coral reef and encased in clear acrylic, offering diners 270-degrees of panoramic underwater views.  The restaurant is reached by a wooden walkway from the nearby over-water Sunset Grill Restaurant, and seats just 14 people for exclusive dining with a real difference.

Hilton Maldives Resort & Spa’s unique undersea restaurant features 360° views of reef and marine life, and one can sip champagne cocktails and sample Maldivian-Western fusion cuisine at the world’s only all-glass, undersea eatery.

Advance reservations recommended.

Key Largo underwater hotel

cell72.jpg
Have you slept underwater lately?

When guests visit Jules’ Undersea Lodge in Key Largo, Florida, they discover that the name is no marketing gimmick. Just to enter the Lodge, one must actually scuba dive 21 feet beneath the surface of the sea. Jules’ really is underwater. Diving through the tropical mangrove habitat of the Emerald Lagoon and approaching the world’s only underwater hotel is quite an experience. Even from the outside, Jules’ big 42 inch round windows cast a warm invitation to come in and stay a while, relax and get to know the underwater world that so few of us have even visited.

Entering through an opening in the bottom of the habitat, the feeling is much like discovering a secret underwater clubhouse. The cottage sized building isn’t short on creature comforts: hot showers, a well stocked kitchen (complete with refrigerator and microwave), books, music, and video movies. And of course there are cozy beds, where guests snuggle up and watch the fish visit the windows of their favorite underwater “terrarium”. Jules’ Undersea Lodge manages to reach a perfect balance of relaxation and adventure.

Guests sometimes describe their visit to inner space as the most incredible experience of their lives. One couple decided on a career change after visiting Jules’ Undersea Lodge, and they now operate Aquanauts’ Dive Shop. Another couple named their baby after Jules’, when they later discovered their recently conceived child had accompanied them in their wonderful adventure in undersea living.

Replica antique sub busted near cruise ship

lg.jpegPolice arrested three people after spotting a replica of the Bushnell Turtle, a submarine invented at the end of the 18th century, semi-submerged near the docked Queen Mary II in the New York City Harbor.
Police held (the sub’s pilot Philip) Riley, and two other men, both from Rhode Island, for questioning. But there was no indication the trio meant any harm with the replica of the 1776 “Turtle submarine.”

One of the Rhode Island men claimed he was descendant of David Bushnell, the inventor of the original one-man vessel that inspired the replica, police said.

The self-propelled submarine was escorted by police and Rey was issued a Coast Guard violation for operating an unsafe vehicle and violating the security zone around the Queen Mary II.

Ancient reef is world’s largest

reefbelt.jpg

The Great Barrier Reef on the northeast coast of Australia is a spectacular sight from the air, stretching over a distance of some 2000 kilometres. From its southernmost parts among the coral cays of the Capricorn Group to its northern limit near the Murray Islands in the Torres Strait, this giant among organic structures is a changeable creature. In places there are widely scattered reefs, about 2500 in all; elsewhere it grows as a nearly continuous wall of coral. The reef builders, mostly colonial corals and their millions of animal and plant neighbours, have slowly fashioned the bioengineering marvel we see today.

But if we could travel 160 million years back in time, we would see another reef in an area that occupied most of what is now Europe. At first sight this reef and its communities have striking similarities to the Great Barrier Reef. But this ancient reef structure is unique; its main architects were not corals, but multicellular marine sponges, many of which have no match today. And this reef was even bigger than the Great Barrier Reef. Its fossil remains stretch about 2900 kilometeres from southern Spain to eastern Romania, making it one of the largest living structures ever to have existed on Earth.

This reef is exposed today in a vast area of central and southern Spain, southwest Germany, central Poland, southeastern France, Switzerland and as far as eastern Romania, near the Black Sea. Despite the scale of this buried structure, until recently researchers knew surprisingly little about it. Individual workers had seen only glimpses of reef structures that formed parts of the whole complex. They viewed each area separately rather than putting them together to make one huge structure. The problem was compounded by the lack of scientific cooperation mand exchange of information between European adversaries during and after the First and Second World Wars. The geological technology was certainly available to assemble the pieces of this palaeontological puzzle into one, but knowledge was lagging behind.

SF Bay underwater dunes

mn_sand_wave_image_usgs.jpg

San Francisco long has been renowned for its hills, bay and bridges — but not for expanses of sand dunes. That’s liable to change.

It turns out there are more than 2 square miles of dunes right next to the city, and world-class dunes at that: Only a few sites around the globe have larger dunes of this sort.

Access, however, will remain difficult unless you’re a sand dab or Dungeness crab. The dunes are just west of the Golden Gate, submerged in 100 to 350 feet of sea water.

Scientists grasped the extent and size of the underwater dunes — technically known as “sand waves” — only recently, aided by sophisticated, multiple-beam sonar that provides stunningly detailed images of the submarine topography.

“These are some of the largest sand waves in the world,” said Patrick Barnard, a coastal geologist with the Santa Cruz office of the U.S. Geological Survey. “They’re certainly in the upper 10 percent.”

The sand waves range up to 700 feet long and reach heights of more than 30 feet, Barnard said. It is a dynamic system, he said, with the configuration of the individual dunes changing significantly with each tidal cycle. But overall and over time, the net change to the entire field is slight.

Robots Clear Waterways of Deadly Mines

transphibian.GIF

PANAMA CITY BEACH, Fla. (AP) — As it slowly moves in the shallow water along a beach, the robot splashes its fins like a small child playing in the surf. But the prototype device has a serious mission: destroying mines that could kill Marines and Navy SEALs as they come on shore. Such technology is considered the future of underwater bomb detection.

“It’s a kamikaze vehicle, a suicidal robot,” said Mathieu Kemp, a scientist with Durham, N.C.-based Nekton Research, LCC, which created the Transphibian.

The 3-foot-long device, which will some day carry 14 pounds of plastic explosives and attach itself to an underwater bomb before igniting, can be maneuvered by a joystick, which Kemp demonstrated last month at the Autonomous Underwater Vehicle Fest, an annual two-week gathering of researchers who design robots for military use.
