The Swedish "Vasa," reclaimed from the Baltic Sea after 300 years as an underwater wreck
Wreck diving aficionados beware: the Baltic Sea might just make you addicted to high adrenaline scuba. Experts estimate that over 50,000 wrecks lie at the bottom of this little-dived body of water located between the main European continent and Scandinavia. Centuries old shipwrecks dating from medieval times to the world wards have been found, with tens of thousands more just waiting to be discovered. Best of all, the ships are very well preserved because of the water’s low salinity and the fact that ship worms that eat wooden wrecks don’t live there. The result is sea floor crafts in pristine condition for divers.
Have you ever dove a wreck and thought “Nice boat, but I have no idea what I am actually looking at.” Instead of just diving a no-name sunken ship, isn’t it so much sexier to dive Peter the Great’s warship, the “Portsmouth?” Frequently, the story behind the boat and the details themselves make the dive even more exciting. The high quality of the Baltic Sea wrecks and their artifacts frequently enable researchers to determine the origin and time period of the ship, if not identify the specific ship itself. So, would you prefer to dive “joe’s tug” or, alternatively, the “Oleg,” a cruiser built in St. Petersburg in 1901-1903 that was sunk by an English torpedo on July 8, 1919? The appeal of diving Baltic Sea wrecks is undeniable.
But make no mistake; wreck diving in the Baltic Sea is not a beginner’s pursuit. Strong currents and bone-chilling thermoclines can make the venture unpleasant at best. Though plenty of wrecks lie along the coasts, many are below recreational dive limits and require decompression diving. And the sad truth is that climate change is causing Baltic Sea temperatures to rise, which in turn is enabling the ship worm to start inching into formerly uninfected Baltic waters along the German and Swedish coasts.
But for a diver with a penchant for wrecks, the Baltic Sea is not to be missed. About a year ago, a team of archeologists carried out the “Secrets of the Sunken Ship” project, identifying 30 more Baltic wrecks of historical importance such as a Li-2 aircraft belonging to the First Long Range Aviation Division Guard downed in 1944, the German boat the “Frida Horn,” and the Swedish “Hanhoot,” built in 1892. Their findings add to the existing list of known wrecks, and more are continuously being added. The Baltic is so rich with wrecks, sometimes discoveries are almost comical. A gas company building an underwater pipeline between Germany and Russia had to repeatedly stop their progress as they unearthed no less than 12 wrecks, some dating back 800 years.
Whether you think of Great White Sharks as ferocious or just misunderstood, you have to admit they are exciting animals. Due to their nomadic lifestyle and periodic deep water forays, we have limited knowledge about them, which perhaps adds to their mystique. We do know that these powerful sea-dwellers can grow to over 20 feet and live to upwards of 100 years. They are found in almost all coastal and offshore waters which have water temperature between 54 and 75 °F, with greater concentrations off the coasts of Australia, South Africa, California, the northeastern US, Mexico’s Isla Guadalupe, New Zealand and the waters of the Mediterranean. Their preferred habitat is the cooler, deeper waters of the ocean and the waters around oceanic islands and rocky outcrops where deep water is within easy reach.
Great Whites are truly apex predators. They are capable of sensing the blood of an injured animal from over a kilometer away. Their Ampullae of Lorenzini organ, which enables them to detect and stalk the electromagnetic field emitted by the movement of living animals, can detect movement that generates as little as half a billionth of a volt. Though Hollywood has spectacularly portrayed them as preferring humans for lunch, they actually live on a diet of fatty fish and animals such as rays, tuna, smaller sharks, dolphins, porpoises, whale carcasses, seals, sea lions, and occasionally sea birds. Diving with Great White Sharks is certain to be on anyone’s list of Most Extreme Scuba. So, where can aquanauts meet these beauties eye to eye?
• Farallon Islands, California, USA – The Farrallones are located 28 miles west of San Francisco. A protected National State Wildlife Refuge since 1969, the Farrallones are an important research spot for great whites. These islands are one of the few places in the world where great whites can be observed in predatory attacks upon seals, birds, and sea lions from dry land. But doesn’t getting in the water with them sound like such a better idea? Cage diving is offered from late-September through November. Divers are offered a tank/regulator or a hookah setup. Since random chumming of the water is illegal in the Refuge, operators often pull along seal “decoys” to attract the sharks. It is an amazing day trip from the city, with many of the operators leaving right from the tourist hub of Fisherman’s Warf.
• Isla de Guadalupe, Pacific Coast, Mexico – Guadalupe Island is a volcanic island about 145 miles offshore of Baja Mexico, 200 miles south of San Diego. Due to the remote location of the island, this trip is done via a live aboard operation over multiple days. The island has a dramatic sheer rock wall extending hundreds of feet up into the air, as well as hundreds of feet into the ocean. The islands’ large population of seals attracts the white sharks in large numbers. The rocky outcrops of the islands have dramatic drop-offs around the edges that reach down into cool, deep water, also attracting our toothy friends. Visibility at this site is fantastic, up to 100 feet or more. Also, the water temperature ranges from 67 to 70 F, making it much warmer than some other Great White watching spots.
• Dyer Island, False Bay, South Africa – South African Great White cage diving occurs mainly in False Bay and the Whale Coast. Dyer Island is a small, low, and rocky island located just offshore from Gansbaai in the Western Cape of South Africa. During winter, the warm Agulhas Current sweeps down from the Indian Ocean, meeting the cold Benguela Current, creating a temperate zone just off the South African coast – providing ideal conditions for the Great White Shark in particular. This island serves as a breeding ground for a wide variety of seabirds, while its neighbor, Geyser Rock, serves as a home for a large resident seal population. White Sharks are seen on a regular basis in the channel between the two islands (“Shark Alley”) where they feed on a variety of seals, seabirds, and penguins. As an added bonus, Great White sharks in these waters often display very unusual, but highly spectacular breaching when chasing their prey, which makes for some amazing topside photos.
• The Neptune Islands, South Australia – The Neptune Islands sit on a shelf south east of Port Lincoln off South Australia. Grey granite and coastal loam make up these picturesque islands, which support an array of wildlife, including many bird species, a large colony of fur seals, as well as a colony of endangered Australian sea lions. Known as the place where the hit movie “Jaws” was filmed, the waters around these islands are a natural feeding area for Great Whites. Most shark diving here is done via a live aboard vessel. Operators practice cage diving combined with surface bait to give divers an unforgettable experience, sometimes with more than one Great White in sight at a time. The water is very cold here, but the shark action is definitely hot.
• Lampedusa, Sicily, Italy –Have you swam off the coast of Sicily or found the offshore waters of Nice to be nice? Oh yes, there were Great White sharks there, and you didn’t even know it. Great White sightings are becoming more common in the Mediterranean, where a high concentration of nutrients attracts some of the whites’ favourite snacks: large pelagic fish, dolphins and turtles. There have been numerous sightings of the Whites along the Spanish, French, Italian and Croatian coasts, but by far the largest concentration of the sharks is in the channel between Sicily and Tunisia. As far as I can determine, no one does cage diving here because of the infrequent nature of the sightings. However, there are many dive companies that operate out of Lampedusa, Sicily, which puts you in waters with the highest density of Great White sightings in all of the Mediterranean. Divers have encountered large white sharks while diving in the open sea at Sicilian Channel sites such as Pantelleria, Malta, and southwest Marretimo. Though rare, these experiences are as amazing as you can get: no chumming, no decoys and no cage bars between you and the jaws of the Great White.

Sexy Cephalopod
Few creatures are as exciting to spot underwater as an octopus. They are smart and good at camouflage, so finding one is always a treat. Plus, they are just beautiful animals to see, with lots of color, shape and size variations. These creatures come in a wide range of options, some as little as an inch, some as large as 16 feet across. The octopus inhabits many diverse regions of the oceans around the world, especially coral reefs, and can exist in water depths from tidal pools all the way down to over 200 feet. For defense against predators, they hide, flee quickly, expel ink, or use color-changing camouflage. Scientists say that most of an octopus’ behavior is learned, not innate, a minor miracle since their lifespan is so darn short (5 years at the absolute most!)
There are about 300 recognized octopus species in the world, too many to cover in depth. But, some are amazing, even by octopus standards, and are worth a mention:
Mimic Octopus – This octopus only lives for 9 months, but boy it accomplishes a lot during that time. This crazy cephalopod takes on the appearance of other species to scare off predators and find food. Imagine a creature burying all but its eyes and two arms below the sand, leaving in view a long thin object with white and black bands running across the elongated body that looks just like the local sea snake. Now you’ve got the mental picture of why the Mimic Octopus is so unique. It usually imitates venomous species, like a lionfish, sea snake, or a poisonous flatfish, though people have also described it looking like a stingray, a crab, and other types of less lethal sea life. Divers can find this octopus off the Indo- Malay archipelago, especially around Sulawesi. Don’t worry though, it isn’t poisonous to humans.
Caribbean Reef Octopus – The Caribbean Reef Octopus isn’t the best looking octopus out there, but if you have been scuba diving in the Caribbean and seen an octopus, chances are this is the most likely suspect. It is common throughout the Western Atlantic, Bahamas, Caribbean and the coasts of northern South America. It is often found at night feeding on reefs and sea grass beds. They have a distinctive blue-green color with occasional mottled-brown markings. Because their blue-green skin is so reflective, they are easy to spot at night with dive lights. Like other octopus species, the Caribbean reef octopus is solitary animal and able to quickly change color using specialized cells in their skin known as chromatophores. They can weigh up to 1.5 kg, but have been known to wedge themselves into miniscule reef crevices and wreck holes.
Wonderpus Octopus – The Wonderpus Octopus has got to be the sexiest cephalopod out there, with a striking color pattern of white bars and spots over a brown-red background. It’s characterized by a small mantle (the part of the body that contains the mouth and vital organs), which is about an inch to an inch-and-a-half long, and long arms that measure about five to seven times the length of the mantle. Its patterns of spots (on the body) and stripes (on the arms) are unique to each individual adult wonderpus, making identification of a specific creature possible. Divers can find the wonderpus in shallow waters from Bali and Sulawesi north to the Philippines and east to Vanuatu, and will fare best looking for the creature when it is most active in the twilight hours of dusk and dawn. This creature is a relative newcomer to the fish identification guides, with the first identification happening only in 1980. Go ahead, say it: won-der-pus. Even its name is sexy.

Blue Ringed Octopus
Greater Blue-ringed Octopus
– No discussion about octopi could be complete without mentioning the little one we love to hate, the Blue-ringed Octopus. Unlike its southern brethren, the Blue-lined and Southern Blue-ringed octopuses that are found only in Australian waters, the range of the Greater Blue-ringed Octopus spans the tropical western Pacific Ocean. Greater Blue-ringed Octopuses can weigh between 10 and 100 grams, though the average is 55 grams. The blue-ringed octopus is the size of a golf ball, but its venom is powerful enough to kill humans, and no known antidote exists. Remember the James Bond movie Octopussy? Yes, it’s that one.
White-spotted Octopus – Humans have been watching the white-spotted octopus since 1826 when it was first spotted off the coast of Nice in the Mediterranean Sea. It spends its adult life on the ocean bottom, and although divers usually see this octopus hanging out near-shore it sometimes it can be found much deeper. This octopus has long arms, with the first arm pair being the longest and stoutest, and has shallow webbing among the arms. It also has a higher sucker count than most octopuses. This is a nocturnal creature, waiting until night to find its favorite snacks of clams and crabs. The white-spotted octopus only lives for 1-2 years after which it goes out with a “bang” (literally) after a single breeding season.
Giant Pacific Octopus – This is the big daddy of all octopi, the Giant Pacific Octopus. As the name would suggest, it is the largest species of octopus in the oceans, averaging 16 feet across and weighing an average of 120 lbs. It is also the longest lived, at 4-5 years. Divers can spot this behemoth from southern California, northward along the coast of North America, across the Aleutian Islands, and southward to Japan, though they usually hang out quite deep, typically at around 215 ft. But just because they are big doesn’t mean they are beautiful: Giant Pacific octopuses have huge, bulbous heads and are generally reddish-brown in color. Like the other members of the octopus family, though, they use special pigment cells in their skin to change colors and textures, and can blend in with even the most intricately patterned corals, plants, and rocks.

Ohhh...shiny
If a tree falls in the woods, but no one is there to hear it, does it make a sound? If a person dreams up a gynormous yacht, but never builds it, do they get to claim they now have the biggest boat? Belgium-based Emocean Yacht Design recently unveiled plans for an extravagant new mega yacht, tentatively called Project 1000, that — if built — would be the world’s largest vessel of its type. The key being “if built” of course. The yacht would be a ridiculous 656 feet, and cost in the absurd range of $500 million to $900 million to build. That means if you won both the PowerBall and Big Game lotteries, you still couldn’t afford this behemouth.
Of course, for all of that cash you do get some sweet perks. For one, the ship does look sexy as heck. In addition to good looks, the design includes a 100-foot swimming pool, health spa, nightclub, casino, a dual-level cinema, drive-in garage, two 98-foot day boats and a helipad with a hanger. You can bring 44 of your best dive buddies with you wherever you go and also include 70 crew members, so you’ll never sail alone, or have to lift a finger while onboard.
So, Emocean did get quite a bit of press for their announcement, but the reality is that no one has jumped up to order this luxury good yet. Even when (if) they do, the company says it will take another 4 years from the date of order until completion. Perhaps by then they will figure out how to squeeze in a dive shop onboard.
You are diving a wreck when you find a shiny trinket that appears valuable. Do you:
a) Leave it where it is..you still remember kindergarten when you learned to “look with your eyes, not with your hands”
b) Hide it in your bathing suit (remember that scene from Pulp Fiction…) you will study it later and hopefully make a million dollars off of it
c) Proudly display it to everyone you com in contact with until the local authorities cart you off to jail for stealing national treasures
CNN recently ran a story about a diver who found a pocket watch near a wreck, and decided to go with a modified version of choice b above. Instead of looking to make a million on it, he spent 9 years researching the history behind it and looking for the current-day, rightful owner.
The story got me thinking about the possibilities of the sunken treasure that lies beneath the waves, and the possibilities of turning my aquatic hobby into a money making venture. After some research I have learned that, sadly, there is no direct line from the sea floor to my pocket. Underwater treasure hunting is governed by the U.N. Law of the Sea, which is about as straightforward as a slinky. The original ship owner, the location of the wreck, the contents of the cargo, the phase of the moon and even the number of goals last scored by Manchester United all seem to play a part in the ultimate meaning of “finders keepers.”
Many privately owned underwater archeology companies (ie. treasure hunters) ply the planet’s oceans each year looking for riches. You’d be hard pressed to actually name one of these companies, however, as they are more secretive than the SPECTRE bad guys in the old James Bond movies (but actually have access to even cooler gadgets.) One such company found $500 million in coins last year, shipped it all back home, buried it in their backyard, then raised their hand and said “Um…we think we might have found something.” The Spanish government is still trying to get the booty back, resorting to armed encounters and public claims of grave robbing in order to “persuade” the salvage shop to return the loot.
Since I’ll be spending my lottery winnings on that $95 million orca yacht, I won’t be able to afford the high tech toys needed for the salvage operation. And since this blog is gathering a healthy following of divers, it looks like the secrecy requirement isn’t going to work either. Guess I’ll have to stick to salvaging the usual abandoned dive gear and old bottles…although a piece of Andrea Doria china would be nice.
