(CNN) — In March 2022, the world let out a collective gasp when the remarkably preserved shipwreck of Ernest Shackleton's HMS Endurance was discovered almost two miles beneath the icy Antarctic seas.
But scores more sunken vessels remain on the ocean floor, awaiting rediscovery.
Here are some of the world's most infamously elusive shipwrecks, plus a few you can see for yourself (some without even getting wet).
Santa Maria, Haiti
A lowly cabin boy shouldered the blame for the sinking of Christopher Columbus' Santa Maria flagship off the coast of Haiti on Christmas Eve 1492. The inexperienced sailor is said to have taken the wheel after Columbus went for a nap, and shortly after wrote off the ship by crashing it into a coral reef.
That's one theory, anyway. However the Italian explorer's ship met its fate, excitement bubbled over in May 2014, when archaeologist Barry Clifford claimed he'd chanced upon its long-lost wreck.
Maritime history buffs' hearts sank after UNESCO poured cold water on the claim, saying the ship that'd been found was from a much later period.
The Santa Maria is still down there, somewhere.
Flor de la Mar, Sumatra

This 16th-century merchant ship -- or "carrack" -- shuttled between India and its home in Portugal. But given its mammoth size -- 118 feet-long and 111-feet-high -- it was an unwieldy beast to captain.
Perhaps it was only a matter of time before the Flor de la Mar went down, which it did in a heavy storm off Sumatra, Indonesia in 1511.
Most of the crew perished, and its booty -- said to include the entire personal fortune of a Portuguese governor, worth a cool $2.6 billion in today's money -- was lost.
SS Waratah, Durban (South Africa)
It may not have its own theme song sung by Celine Dion, but the SS Waratah is known as "Australia's Titanic" -- and for good reason.
A passenger cargo ship built to travel between Europe and Australia with a stopover in Africa, the Waratah disappeared shortly after steaming off from the city of Durban in present-day South Africa in 1909 -- just three years before the Titanic tragedy. As for the cause, theories abound.
The entire liner, complete with eight staterooms, music lounge and all 211 passengers and crew, was never found. Ninety years after the Waratah went down, the National Underwater and Marine Agency thought they'd finally found it, but it was a false alarm.
Said the late thriller writer Clive Cussler, who spent much of his life searching for the wreck, "I guess she is going to continue to be elusive a while longer."
USS Indianapolis, Philippine Sea
Rotten Tomatoes' "Tomatometer" might rack up a rancid 17% for the 2016 Nicolas Cage movie, "USS Indianapolis: Men of Courage," but in real life, the ship played a game-ending role in World War II.
The Indianapolis was chosen to transport the uranium core of the "Little Boy" nuclear bomb to Tinian Island, where the weapon was assembled shortly before being used to devastating effect on Hiroshima.
The drop-off of the deadly cargo went without a hitch, but on its return journey, the Indianapolis was hit by a Japanese sub, with many crew members perishing from shark attacks and salt poisoning.
The exact whereabouts of the warship remained a mystery for decades, but was finally located by a team led by Microsoft co-founder Paul Allen, in 2017 -- 18,000 feet below the surface of the Pacific.
Slave ships, North Atlantic Ocean

Not just one shipwreck, but an entire ghastly genre of them.
It's estimated some 1,000 ships now on the bottom of the ocean were complicit in the wicked "triangular trade" across the Atlantic that saw some 12-13 million Africans forced into slavery.
Many of these ships sank in turbulent weather, such as the São José, which went down off the coast of South Africa in 1794.
Others, like the Clotilda, were purposefully scuttled by their owners, to cover up evidence of slave trading, long after the 1807 Act Prohibiting Importation of Slaves.
The wrecks of both these vessels have now been located -- the São José thanks to the work of Diving With a Purpose (DWP), a group of largely Black scuba divers who dive on the sites of sunken slave ships, and bring the likes of rusted manacles and iron ballasts to the surface.
It's impossible to retrieve such objects without also dredging up stories of human suffering, although DWP's goal is to document slavery's nefarious legacy, using it to educate and enlighten.
Still, such ships are notoriously elusive, and many may never see the light of day again.
Shipwrecks you can visit
Mehmed Çakir was diving for sponges off the coast of Yalıkavak, Turkey in 1982, when he happened upon the remains of a trading ship that had sunk here some 3,000 years previous.
His was the first of many dives -- over 22,400 in fact -- to bring up the long-lost treasures of the Uluburun, and what a haul it was; 10 tons of copper ingots; 70,000 glass and faience beads; olive oil and pomegranates stored in Cypriot pottery jars. Some of the horde can now be seen at the Bodrum Museum of Underwater Archaeology, and while not much of the Bronze Age wreck survives, there's a cross section reconstruction, which gives a feel for how it would have been stacked with all those goods, all those centuries ago.
The Vasa, Stockholm

Eerily intact, the 17th century warship Vasa looks more like a prop from the "Pirates of the Caribbean" franchise, than a ship that first (and last) set sail in 1628.
The Swedish behemoth made it about 1,300 meters out of port before it went down, and was only pulled from its silty grave some 333 years later.
A crew of archaeologists (who took typhoid and tetanus jabs to protect themselves from various bacterias) discovered a hull bristling with 700 sculptures and decorations of mermaids, lions and Biblical figures -- what has been described as essentially a "gigantic billboard for Sweden and Gustav II Adolf," the country's redoubtable king of the time.
Since a dedicated museum opened in Stockholm in 1990, the Vasa has become one of the world's least elusive shipwrecks, ogled so far by some 25 million visitors.
MV Captayannis, River Clyde
Spied from the banks of the River Clyde at Greenock in Scotland, you might mistake the wreck of the MV Captayannis for a recently demised whale.
The black hull of this Greek sugar-carrying boat, rolled onto its side, is a favorite perch for feathered residents of a nearby bird sanctuary -- and has been, since the ship went down in a squall in January 1974.
It's said no one took responsibility for the so-called "sugar boat," hence why it's still wedged into a sandbank -- a gauche reminder of the sea's capriciousness.
Still, it's a blessing for local boat charters like Wreckspeditions, who'll take maritime rubberneckers up close, while pouring them a hot chocolate.
Chuuk Lagoon, Micronesia
If scuba diving is what floats your boat, chances are you've heard of Chuuk Lagoon.
On this sprinkling of islands 1,000 miles northeast of Papua New Guinea, the Japanese set up their most formidable World War II naval base -- that is, until Operation Hailstone was launched in 1944, with Allied forces sending some 60 Japanese ships and aircraft to a watery grave.
With most of them still down there, Chuuk Lagoon has become a mawkish subaquatic museum for divers to gawk at barnacled tanks from the San Francisco Maru or the long-abandoned compass and engine telegraphs of the Nippo Maru.
MS World Discoverer, Solomon Islands
"Open 24 hours" declares Google Maps optimistically about the shipwreck of the MS World Discoverer.
Since the cruise ship MS World Discoverer struck something hard, and half-sank off the shores of Roderick Bay in the Solomon Islands in 2000, it's become a tourist attraction for passing ships (all passengers, it should be pointed out, were helped to safety).
Gently rusting away, at a 46-degree list, the ship looks like it turned on its side, and went to sleep. If nothing else, it'll have you counting the lifeboats on your own vessel as you sail by.
