The authors of this chapter, Horgan et al. propose a real-time navigation system for a UUV that takes advantage of the complementary performance of a sensor suite including a DVL, a compass, a depth sensor and altimeter sensors with a feature based motion estimator using vision (Horgan et al. 2007). The compass and the depth sensors are used to bound the drift of the heading and depth estimations respectively. The altimeter is required in order to translate the feature displacements measured from the images into the metric displacements of the robot. While the robot must rely on DVL navigation above a certain altitude where vision is less effective, DVL measurements can be complemented with higher frequency accurate motion estimates from the vision system when navigating close to the seafloor. When a vehicle comes close to the seabed, DVL can drop out due to minimum blanking range, however at such short ranges vision systems are at their most effective. From the reviewed papers it is...
The sub-tropical island of Bermuda is proud of its healthy coral reefs, its friendly people and its reputation as a clean and safe destination. Three hundred shipwrecks spanning five centuries surround the beautiful coral island which is only a two-hour flight from most U.S. east-coast gateway cities. Up to 20 of the most popular shipwrecks are accessible from Bermuda IV. As a memento of diving on any of these special wrecks, guests will receive a Bermuda Shipwreck Certificate. On-shore excursions to special places of interest are also part of the Bermuda IVexperience visit the Bermuda Underwater Exploration Institute, home of Teddy Tucker's famous treasure the Bermuda Maritime Museum located in the heart of the 19th Century Royal Naval Dockyard or the historic town of St. George's, now a World Heritage Site.

Most Autonomous Underwater Vehicles (AUVs) today are larger ones applied extensively from environmental monitoring to oil and gas exploration (Yuh, 2000). However, these AUVs are not suitable for applications where the vehicle has to explore confined spaces like ship wrecks or oil pipe lines, where maneuverability and stability are more important than speed. Tasks such as these call for designs that are small, maneuverable and precisely

It contains the maneuverability in horizontal (turning radius and turning rate) and vertical (rising and submergence). Usually the shipwreck site is rough and complex, so the robot maneuverability can guarantee the success of the archaeology task. The robot should have local intelligence. It could track the sea-bottom landform and avoid obstacles (independently) autonomously. Generally, the stable depth of the underwater robot is relative to the sea level. But the archaeology exploration task needs to follow the contour line relative to the sea-bottom, which involves tracking of sea-bottom landform. In addition, for the sake of safety, the robot ought to have the capability to avoid obstacles independently. The robot should have small size, light weight and low cost, which are considered from application and popularization. Robot with large size and heavy weight could bring trouble when putting and retrieving. In order to enhance the maneuverability, the...

At present, SPC-II can elementarily fulfill the need of underwater archaeology and it also has some advantages in environment disturbance and horizontal maneuverability. But the ascending and submergence of SPC-II are implemented by changing the pectoral fin's incidence angle, so it can dive only in the process of swimming (submergence velocity is the minimum straightforward velocity of submergence). In addition, it can not swim back off and hasn't the underwater position system. All of which bring more difficulty to underwater pointing task. Moreover, SPC-II is only a robot prototype with simple equipments it can only help the archaeological team to complete the second phase task. Donggu gulf site of shipwrecks in Dongshan city, Fujian Province is in a gulf, and the offing is much calm, but the water quality is much turbid (especially when is ebbing).

On a repeat visit to Coron, I had a pleasant time diving on the wrecks and we spent one night bivouacking on a tiny island where the weather looked a bit dodgy. Expecting possible weather problems, I took all my cameras ashore including two housed cameras that were already connected with synchronization cables to flash guns. On the first dive the next day one of my flash guns began firing off continuously like a strobe light. I struggled with this unit for several days, double checking all connections and fitting the housing with twin-flash, it worked fine in air but every time I took it into the water it malfunctioned. Eventually I spotted the tiny impression of a rat's teeth on the synchronization cable, 70 of synchronization cable and several dives destroyed by a hungry rodent Animals often take a liking to the odour of silicone rubber, on a Malaysian island I once found squirrels eating my guide's silicone rubber mask.

Wooden shipwrecks are a rarity in the oceans for one main reason they are devoured at a tremendous rate by shipworm. However, the northeast Baltic is rather a special place. The Baltic Sea is actually a very large estuary, salty at one end and fresh at the other, and by the time we get to Finland, the water is too fresh for many marine species to survive, including shipworm. This makes it the best place in all the oceans for diving on ancient wooden shipwrecks. While the conditions off southern Finland are excellent for wood preservation, they are not ideal for photography, especially the photography of a 26m long and 7m wide shipwreck. The aim of Jukka's expedition was to take the first images that with our well used methods to guarantee a high strike rate of good shots when we dive. However, persevering with a new technique and technology adds another weapon to our photographic armoury. My experiences with the tripod not only got the job done for me, but also taught me a new...
With an increasing number of military and civilian wrecks Lethbridge was quite successful with his invention and participated in salvaging a number of European wrecks. In a letter to the editor of a popular magazine in 1749, the inventor noted that his normal operating depth was 10 fathoms (60 feet),
Bermuda is widely acknowledged as the wreck-diving capital of the Atlantic. Ask anyone who's even casually informed about dive travel, and they'll tell you that Bermuda is the wreck-diving capital of the Atlantic. And that's true amazing shipwrecks such as the paddlewheel steamer Mary Celestia and the Rita Zovetta whose stern is still intact after 82 years underwater keep divers coming back for more. Some, such as the Hermes, are completely intact, but others, such as L'Herminie, are marked only by the coral-encrusted remains of their long-silent cannons.
Statia has several wrecks as well as the usual barrel sponges and gorgonians that cover Caribbean reefs perfect for wide angle photography, both natural light and with a touch of strobe. And there were plenty of critters for macro Sailfin blennies, Pike blennies, Yellow headed jawfish (stuff I'd never seen) and more. This was no ordinary 'wrecks and reefs' Red Sea tour. We moored in two places over the six days - at the Alternatives near Ras Mohammed for reefs, and at Sha'ab Abu Nuhas for wrecks - and again made multiple visits to the same dive sites. This provided plenty of opportunity to take full advantage of the changing light on the wrecks,
In a single word, as I'm not sure the editor would publish my expletives, stunning. At 800 ISO you just cannot tell the difference between 200 ISO. So for the macro shooters depth of field is back again by simply turning up the ISO enabling you to shoot at f22 or above, as I did after a disappointing macro dive using f11, an aperture that was OK when I previously used with the D2x. And what about higher At ISO 1600 & 3200 there is very little noise, if shooting wrecks or larger animals it

This rich archipelago in the southern part of the northwest Pacific Ocean has become known as a diving haven that attracts scuba buffs from all over the world. The anchor of a geographic region called Micronesia, it is part of a rich triangle that includes the Philippines, Papua New Guinea and Palau in one of the most diverse undersea places on Earth. The coral reefs, deep dropoffs, sheer walls, enclosed marine lakes, wartime shipwrecks and a plethora of other marine attractions make this a place that any skill level of diver can enjoy.
Schilling's latest manipulator arm - the Titan 3 - has become famous. The arms are in use as part of the Odyssey Marine Exploration. Schilling Robotics provides Titan 3 manipulator arms with integrated positioning sensors and software to Odyssey Marine Exploration and its Remotely Operated (undersea) Vehicle (ROV), which has been working on the noted HMS Sussex Project.
There are dive sites in Malaysia and Borneo where you can swim with turtles and then ascend through swirling cylinders of silver barracuda. There are pristine coral atolls, schools of undulating, scalloped hammerhead sharks and caverns here, including one spooky cavern where, it is said, sea turtles go to die. Wrecks, walls, macro muck and coral gardens this is one part of the world where you can literally find it all.
Yap's Rainbow Reef is an inner lagoon coral reef area near the mangrove forest. This is where the exquisitely colorful, but tiny and reclusive, mandarinfish live and come out at dusk to breed and do mating rituals. Sea grasses, sandy shallow channels, deep main channels, outer hard coral reefs and even the remains of an 1800s copper plated and wooden shipwreck all produced special critters .
An early attempt at using a model with a video light. I took a series of shots of my wife Sylvia exploring a swim-thru on one of the wrecks at Gubal. I tilted the camera angle to provide a more dynamic diagonal to the composition. I placed the light on the 'thirds' intersection to aid composition. The bubbles were luck but once again I think a subtle enhancement. I took about 6 shots of this idea. Nikonos 111 & 15mm lens. 60th sec at F4. Oceanic 2003 on half power.
The first full day was at sites around Derawan Island, with visits to Sangalaki and Kakaban islands planned for the following days. We began at Lighthouse 1, another gentle drift starting on a plateau at 5m which then shelved down to 30m. We gradually made our way back up the slope throughout the dive and saw a variety of multi coloured nudibranchs, blennies, tunicates, wrasse, batfish and a couple of green turtles. On a later dive at this site Eddie found a blue ribbon eel that he teased out of its burrow with a long piece of wire, not a practice I was very happy with, but we did get to appreciate the full beauty of the eel with it's small bright blue and yellow head attached to a long blue sinuous body. The next dive was on an Unidentified Shipwreck and had very similar life to the first, with a couple of large turtles hiding under Overall the diving was very good and at times excellent. El Nino had taken it's toll on the corals but there aren't many places that can offer such a...

For me (a wannabee underwater photographer) on my third trip to PNG in as many years, I was looking for wide-angle reef scenes, World War II wrecks, large marine creatures and a liberal sprinkling of macro critters . Milne Bay seemed to offer all this and more from superb reefs - my favorites are Suzie's Bommy & Di's Delight, to wrecks like the 65m long tanker Pacific Gas & an A20 WW2 Havoc bomber to muck diving at Lion Island. All the diving is done from two purpose built 9m aluminium dive boats and is scheduled around two dives in the morning when the conditions are generally at their best, with a single dive available in the afternoon depending on the weather followed by a night dive on one of the more sheltered locations. Located in 50m of water off the romantically named Boga Boga village, the wreck of the WW2 B17 Flying Fortress bomber is a great, if fairly short dive. There are many wrecks in Milne Bay but this has to be one of the best as it is in pretty good condition...
Navy divers were plunged into the war with the Japanese raid on Pearl Harbor. The raid began at 0755 on 7 December 1941 by 0915 that same morning, the first salvage teams were cutting through the hull of the overturned battleship USS Oklahoma to rescue trapped sailors. Teams of divers worked to recover ammunition from the magazines of sunken ships, to be ready in the event of a second attack.
Moving to tropical waters brings a big increase in the number and diversity of species. In the west the Caribbean has several of scorpionfish which are very close in appearance to their Atlantic and Mediterranean cousins. Moving east to the Red Sea offers a wider range from the elegance and beauty of the lion fish to the perhaps repulsive gargoyle features of the stone fish and a host of alternative creations in between. The common lion fish (Pterois volitans) are unique amongst the scorpion fish as they are often free swimming and use schooling tactics to hunt their prey. They hunt predominantly at night or during the dusk hours and groups of up to twenty or thirty individuals are frequently encountered on reefs and particularly wrecks. Here they will act as a pack to herd their target prey, often schooling glass fish, to a position where each
What does make these Islands popular for divers are the deep ocean currents and dramatic coral walls. In fact these islands are really sea locked mountains with some of their most beautiful scenery under the water's surface. But it's not just the colourful walls that make diving here so interesting, it's also the huge diversity of shallower dive sites and well known wrecks. The Cayman Island authorities are well aware of the treasure they care for. Strong foresight and a strong line on conservation has led them to create marine reserves and permanent mooring buoys on all permitted dive sites. Add to that year round clear warm water ( certainly a treat for a seasoned dry suit diver ) and this really can be a diver's paradise.
Carefully fining my way through a narrow passageway in the dark interior of an old shipwreck I come face to nose with a large shark. Neither the shark nor I can swim very well in reverse so I sink to the bottom of the hallway and try to be small. Undisturbed by my presence, the shark silently glides over me close enough to touch. Figuring that I might as well take a picture, my powerful strobes illuminate the beast at close range. Now very disturbed, the shark bolts out of site with a loud CRACK of her tail. This big girl was circling above the World War II shipwreck of the Caribsea. She was just one of overfifty sharks in the area that day. There was a lot of bait around her and it was difficult to get a clear shot of her head.

Later in the week I again tried the filter with the shoals of snapper that congregate at Ras Muhammad at that time of the year. The results were maybe not quite as good. Seems fish tend to move about a bit, unlike wrecks. With the longish shutter speed the slight movement of the fish made obtaining a sharp image much more tricky.
Lastly, make sure you can see the screen underwater and access all of the important menu functions easily. This is especially important for those who are planning use their camera in temperate waters where gloves make accessing the controls difficult. Make sure you can access the film speed, aperture and shutter speed controls as well as white balance. The latest compacts made by Canon can custom set a button to become a one-touch manual white balance button which can be really useful when taking photographs of wrecks and caves to help bring the colours back in some scenarios. Having the confidence to change film speeds underwater does not only help to control overexposed subjects or blurry fish, but can also give an artistic effect to particular subjects. Film speed or ISO refers to the sensitivity of the camera's chip to. When in lower light conditions, a faster film speed is needed to ensure that subjects are sharp and in focus. When in shallower water, a lower ISO number such as...
One of the major tasks of the Salvor is the refloating of stranded vessels and the clearance of navigable harbor areas of wrecks and grounded ships. Most often this requires the use of underwater cutting equipment. This chapter presents detailed technical information and procedures to be used while engaged in underwater cutting operations. As previously mentioned, there are two methods of underwater cutting currently being used oxygen-arc and shielded metal-arc cutting. Each method is discussed in this chapter.
It is best to start your search with beach dives in early March. This thought alone maybe enough to put most photographers off the chase, but the habitat you are looking for will be often in a depth of less than 10m in amongst the kelp stypes and often in areas subject to heavy surge in rough weather. In recent years I have been lucky enough to find two lumpsuckers who had nested in shallow wrecks where the configuration of the twisted metal provides excellent protection for the eggs and enables the male fish to wedge himself in during storms. It really is quite surprising how these fish
New shipwreck in Grenada The 170 foot 50 m HEMA 1 is now the newest addition to the already diverse portfolio of Grenada's ship-wrecks. Laying on it side, still swaying in the current, in a depth of 30 m 100 feet it will soon become a new attraction. Aquanauts will report and document the growth development on the new wreck regularly. But already it is clear that the wreck of HEMA 1 will be one of the main attractions in Grenada's waters due to its location in the nutrient rich Atlantic current off the south coast where other wrecks like San Juan and King Mitch have an impossible to resist draw on experienced adventure seeking divers
