Fifty years ago , the deep sea vehicleAlvin made its first free dive , submerge to 35 foot below the wave . Since then , DSV Alvinhas been repeatedly overhauled and upgraded , keeping pace with current engineering in myriad dives and endless missions stockpile humans into the mysterious blue sea .
Top mental image : Even octopus get it on Alvin . Or is that murderous rage ? 2008 .
Forging the original Alvin sphere in 1964 .
In 1962 , the Woods Hole Oceanographic Institute ( WHOI ) contracted with General Mills , Almighty of Cheerios , to build a research zep . For $ 498,500 , General Mills built a submersible capable of dive to 1,829 feet while keep on its humans live . Soon , the submersible bring in its name : Alvin , in honour of Allyn Vine , a WHOI scientist who capture the approximation set forth at a group discussion in 1956 . Alvin was formally commissioned on June 5th , 1964 , and made a tryout nose dive in the Woods Hole Harbor workweek by and by on June 26th .
The next year , Alvin and theimprovised catamaranLulucontinued testing , ranging the Bahamas , inspect a hearing array in the Tongue of the Ocean , and dive deeper and deep in longer and longer dive to prevail Navy certification . Ever since then , it ’s been on one serial of adventures after another .

Testing Alvin in 1964 .
The seven - meter farseeing submersible carries a Ti sphere cockpit 2.1 metre in diameter where the pilot and two scientists can peer out at the watery world around them . Although Alvin carries enough air to keep everyone alive for up to 3 days , limitations like the cold-blooded environs and lack of toilet terminal point each diving to about five hours . While uncrewed robotic explorers can rest underwater longer , Alvin provides its crew with a first - manus view of how sea arrangement interact . The submersible can also collect and riposte sample distribution of beast , rocks , sediment or fluid from the seafloor , hauling them to the airfoil for further investigating .
Alvin : research submersible warship ; turkey rescuer . 1966 .
In 1966 , Alvin teamed up with CURV to search for andrecover an hydrogen bomb cast off during a ship collisionnear Spain . The next twelvemonth , the submersible got in a conflict with a swordfish , drag on the fish to the surface where it was fake and eat for dinner . calendar month after , it lost a battle with itself and lost an weapon during a rough recovery which was later recuperate and reattached .
That atomic number 1 dud was around here somewhere … Alvin look for a misplaced bomb calorimeter in 1966 .
1968 was a spoiled yr , when the submarine sandwich fall off its backing rocker and sank . While the pilot get by , Alvin remain at 5,000 feet for ten months until an effective recovery mission could be executed . The accident proved to be an unexpected skill experiment , as the submersible ’s minimum morphologic damage , cold mystifying - ocean temperature , and want of decaying atomic number 8 circumstantially preserve abandoned luncheon for the better part of a twelvemonth . It guide until 1971 to fully restore the vehicle .
The installing of a Modern press hull and ballast system in 1973 earned Alvin an upgraded certification , freeing it to dive twice as deep to 12,000 feet . The following year , Alvin teamed up with a duo of French submersibles Cyana and Archimede to take the first - ever up - tightlipped peek at the Mid - Atlantic Ridge . In 1976 , Alvin was certify for even inscrutable dive , permitted to explore up to 13,124 base below the waves .

From there , the adventure just keep on croak , with rise , discoveries , and close encounters deeper and deeper in the sea . In ’ 77 , Alvin slithered through the Panama Canal and puttered about the Galapagos Rift . Everyone is downright startled to discover whole residential area of thick - ocean organism clustered around venthole . It ’s too dismal for the creature to live off sunlight and photosynthesis , so instead they do chemosynthesis . This sets off an obsession : In ’ 79 , it repeated the journeying , and chance on yet another environs of vent communities clustered around black smoker ” hydrothermal vents . The vents populate up to their names : black , spicy , chemical - productive water gushes from towering vent chimneys . Life clump nearby , process the chemicals to sustain their activities .
The Titanic and Alvin have a personal encounter in 1986 .
By 1980 , Alvin celebrated its 1,000th prima donna by fudge around Galapagos once again . Most of the ’ 80s were pass investigating volcano communities from Washington to California and along the Panama Rise , exploring this raw vista into how and where life can last . After , it wander past Hawaii to nose at itsnewest not - yet - an - island volcano . mayhap most notably within a cultural context , in 1986 the not - so - little submersible carried Dudley Foster and Bob Ballard to research the Titanic .
Foster and Ballard can go a few hours without a toilet if it imply they get to explore the Titanic . 1986 .
In 1991 , Alvin helpfully searched for and recollect the lost removed run vehicle towage system CURV III , then lead northerly to take part in multidisciplinary investigations of the Juan de Fuca ridgeline offshore of the Pacific Northwest . In 1994 , the submersible took on salvage operations once again , this time to hoard a lost university stone drill . By its 30th birthday in 1994 , Alvin posed a philosophic challenge : is it still the same machine when every component and part has been replaced at some tip for repair or upgrade ?

Tight budgets hampered dives throughout the ’ 90s , with repeated inquiry seasons curtailed to keep up funds . Even so , in 1995 the submersible hit another milestone with its 3,000th dive . Alvin father even more raise , adding on laser rangers , operator arms , and assorted bits and pieces to certify it for ever - deeper dives . Between the closing , scientists were capable to look into a whale carcass , revisited the carcass year later when it was a skeleton in the cupboard , had a date with the French submergible Nautile film by the BBC , kept up several retentive - terminal figure enquiry projects , and test out all its shiny new gear .

Alvin kicked off 2000 by divulge yet another antecedently - unknown sea surroundings , this time the “ Lost City ” along the mid - ocean ridge in the Atlantic .
Another year , another new ecosystem . 2000 .
Mantle rocks oppose with brine to build unusual geologic structures , and as seems to go on in every location with chemical substance - rich waters , another unique chemosynthetic biotic community .
In 2002 , Alvin headed back to the Galapagos to check in on vent systems visited yr before , only to find them buried by fresh lava flows , and whole new residential area thriving in the altered environment . A few years afterward in 2004 , Alvin lionise both a 40th birthday and a 4,000th nosedive .

Two years later , Alvin went on an extremophile tear , carry investigator to keep biography in utmost sulphide tightness , carting a different radical of research worker down to marvel at critters who call methane seeps home , and take a hop around the stream communities of hydrothermal vents . Another two years later , the submersible delivered geodetic station to perform recollective - full term monitoring along the East Pacific Rise .

In 2011 and 2012 , Alvin left the water for someserious rebuilding and overhauling , this meter to a intent depth of 4,500 meters . By November of 2013 , it had been try out and certify down to 3,729 meters depth , but they could n’t happen a deeper daub nearby to keep on diving ! For most of this year , the submersible has been tool around the Gulf of Mexico before heading out to Florida in June .
