Daring new search of ancient Antikythera wreck begins today

Over the decades, divers have attempted to investigate the ancient shipwreck, however, the dangerous conditions of the submerged vessel have so far prevented researchers exploring the site fully. The wreck is located at an extreme depth, resulting in the death of one diver and others being paralyzed from decompression sickness. Subsequent attempts more recently have led to more discoveries, including finely carved bronze and marble statues, glassware, jewellery, and coins, but time constraints have prevented a thorough study of the wreck. However, thanks to advancements in technology, the search of the Antikythera wreck can now finally continue.

Earlier this year, marine archaeologists with the American Museum of Natural History came up with an ingenious solution to the challenges posed by the depth of the wreck – they will use a high-tech exosuit developed by Nuytco research, which allows divers to descend to 300 metres for hours at a time without the need for decompressing upon returning to the surface. The exosuit, which is made mostly of aluminium, works like a submarine. It has 1.6 horsepower thrusters, an oxygen replenishment system, LED lights, cameras, and is tethered to the surface with a fiber optic gigabit Ethernet that allows for two-way communications, a live video feed, and monitoring of the suit and its wearer.

I suppose a submarine was out of the question? Demeter Sep 2014 #1
wouldn't have been as cool. The treasure in the ship will go a long way in paying for the suit. :) wyldwolf Sep 2014 #2

The suit's not entirely new JHB Sep 2014 #5
Fascinating, Ichingcarpenter. Enthusiast Sep 2014 #4
Why not just bring the thing to the surface? ReRe Sep 2014 #6
Thank you knownow Sep 2014 #7
Hope we will be hearing more soon. Wonderful. n/t Judi Lynn Sep 2014 #8

I remember seeing photos of what had to be earlier versions of it or that general type of high-pressure suit many years ago, like 15 or 20 years.

And looking it up, various versions have been around for over a century:

An atmospheric diving suit or ADS is a small one-man articulated submersible of anthropomorphic form which resembles a suit of armour, with elaborate pressure joints to allow articulation while maintaining an internal pressure of one atmosphere. The ADS can be used for very deep dives of up to 2,300 feet (700 m)[1] for many hours, and eliminates the majority of physiological dangers associated with deep diving; the occupant need not decompress, there is no need for special gas mixtures, and there is no danger of decompression sickness or nitrogen narcosis. Divers do not even need to be skilled swimmers.

The ADS has variously been referred to as a Winnie the Pooh suit[citation needed] (because of its large head), armored diving skirt[citation needed], articulated diving suit, Iron Duke, Iron Mike, and 'deep-sea diving robot'.[citation needed] The term 'atmospheric diving suit' itself did not come into widespread use until the invention of the JIM suit in the early 1970s.[citation needed]

Atmospheric diving suits in current use include the Newtsuit and the WASP, both of which are self-contained hard suits that incorporate propulsion units. The Newtsuit is constructed from cast aluminum (forged aluminum in a version constructed for the US Navy for submarine rescue), while the WASP is of glass-reinforced plastic (GRP) body tube construction. The upper hull is made from cast aluminum.[clarification needed] The bottom dome is machined aluminum.

The suit mentioned in the OP is called The EXOSUIT, and was designed by the same guy as the "Newtsuit" mentioned in the Wikipedia page:
Nuytco Research Ltd. unveils the future of ocean exploration: The EXOSUIT

Developed and built in North Vancouver by Nuytco Research Ltd, this hard metal dive suit allows divers to operate safely down to a depth of 1000 feet and yet still have exceptional dexterity and flexibility to perform delicate work. The amazing technology of the EXOSUIT atmospheric diving system (ADS) maintains a cabin pressure of the surface and still allows the suit to bend due to a unique rotary joint invented by Dr. Phil Nuytten.

Maybe that's one of the things they are going to look into/survey while they are down there in the special diving suits, e.g. will it fall apart and be destroyed if they attempt to bring it to the surface? Can they bring stuff to the surface one item at a time? How many and what kinds of items are down there? This is going to be interesting to follow. Thanks, Ichingcarpenter!
