me of a new scientific discipline：
oceanography。 they also discovered； by means of depth measurements； that there appeared tobe submerged mountains in the mid…atlantic； prompting some excited observers to speculatethat they had found the lost continent of atlantis。
because the institutional world mostly ignored the seas； it fell to devoted鈥攁nd veryoccasional鈥攁mateurs to tell us what was down there。 modern deep…water exploration beginswith charles william beebe and otis barton in 1930。 although they were equal partners； themore colorful beebe has always received far more written attention。 born in 1877 into a well…to…do family in new york city； beebe studied zoology at columbia university； then took ajob as a birdkeeper at the new york zoological society。 tiring of that； he decided to adoptthe life of an adventurer and for the next quarter century traveled extensively through asiaand south america with a succession of attractive female assistants whose jobs wereinventively described as 鈥渉istorian and technicist鈥潯r 鈥渁ssistant in fish problems。鈥潯esupported these endeavors with a succession of popular books with titles like edge of thejungle and jungle days； though he also produced some respectable books on wildlife andornithology。
in the mid…1920s； on a trip to the gal谩pagos islands； he discovered 鈥渢he delights ofdangling；鈥潯s he described deep…sea diving。 soon afterward he teamed up with barton； whocame from an even wealthier family； had also attended columbia； and also longed foradventure。 although beebe nearly always gets the credit； it was in fact barton who designedthe first bathysphere （from the greek word for 鈥渄eep鈥潱nd funded the 12；000 cost of itsconstruction。 it was a tiny and necessarily robust chamber； made of cast iron 1。5 inches thickand with two small portholes containing quartz blocks three inches thick。 it held two men； butonly if they were prepared to bee extremely well acquainted。 even by the standards of theage； the technology was unsophisticated。 the sphere had no maneuverability鈥攊t simply hungon the end of a long cable鈥攁nd only the most primitive breathing system： to neutralize theirown carbon dioxide they set out open cans of soda lime； and to absorb moisture they opened asmall tub of calcium chloride； over which they sometimes waved palm fronds to encouragechemical reactions。
but the nameless little bathysphere did the job it was intended to do。 on the first dive； injune 1930 in the bahamas； barton and beebe set a world record by descending to 600 feet。 by1934； they had pushed the record to 3；028 feet； where it would stay until after the war。 bartonwas confident the device was safe to a depth of 4；500 feet； though the strain on every bolt andrivet was audibly evident with each fathom they descended。 at any depth； it was brave andrisky work。 at 3；000 feet； their little porthole was subjected to nineteen tons of pressure persquare inch。 death at such a depth would have been instantaneous； as beebe never failed toobserve in his many books； articles； and radio broadcasts。 their main concern； however； wasthat the shipboard winch； straining to hold on to a metal ball and two tons of steel cable；would snap and send the two men plunging to the seafloor。 in such an event； nothing couldhave saved them。
the one thing their descents didn鈥檛 produce was a great deal of worthwhile science。
although they encountered many creatures that had not been seen before； the limits ofvisibility and the fact that neither of the intrepid aquanauts was a trained oceanographer meantthey often weren鈥檛 able to describe their findings in the kind of detail that real scientistscraved。 the sphere didn鈥檛 carry an external light； merely a 250…watt bulb they could hold upto the window； but the water below five hundred feet was practically impenetrable anyway；and they were peering into it through three inches of quartz； so anything they hoped to viewwould have to be nearly as interested in them as they were in it。 about all they could report； inconsequence； was that there were a lot of strange things down there。 on one dive in 1934；beebe was startled to spy a giant serpent 鈥渕ore than twenty feet long and very wide。鈥潯tpassed too swiftly to be more than a shadow。 whatever it was； nothing like it has been seenby anyone since。 because of such vagueness their reports were generally ignored byacademics。
after their record…breaking descent of 1934； beebe lost interest in diving and moved on toother adventures； but barton persevered。 to his credit； beebe always told anyone who askedthat barton was the real brains behind the enterprise； but barton seemed unable to step fromthe shadows。 he； too； wrote thrilling accounts of their underwater adventures and even starredin a hollywood movie called titans of the deep； featuring a bathysphere and many excitingand largely fictionalized encounters with aggressive giant squid and the like。 he evenadvertised camel cigarettes （鈥渢hey don鈥檛 give me jittery nerves鈥潱！n 1948 he increased thedepth record by 50 percent； with a dive to 4；500 feet in the pacific ocean near california； butthe world seemed determined to overlook him。 one newspaper reviewer of titans of the deepactually thought the star of the film was beebe。 nowadays； barton is lucky to get a mention。
at all events； he was about to be prehensively eclipsed by a father…and…son team fromswitzerland； auguste and jacques piccard； who were designing a new type of probe called abathyscaphe （meaning 鈥渄eep boat鈥潱！hristened trieste； after the italian city in which it wasbuilt； the new device maneuvered independently； though it did little more than just go up anddown。 on one of its first dives； in early 1954； it descended to below 13；287 feet； nearly threetimes barton鈥檚 record…breaking dive of six years earlier。 but deep…sea dives required a greatdeal of costly support； and the piccards were gradually going broke。
in 1958； they did a deal with the u。s。 navy； which gave the navy ownership but left themin control。 now flush with funds； the piccards rebuilt the vessel； giving it walls five inchesthick and shrinking the windows to just two inches in diameter鈥攍ittle more than peepholes。
