to me this is the most important part of the year when you come here your one on one with you forget all about civilization. spots left people with a passion for exploration dive down deep. for the sake of scientific research. hunting for treasures from times past. but. the world is one of possibilities unimaginable.

hi glad to see. this case has been pitched on the sure of the black sea every year for the last fifteen. the courage straight as. it separates ukrainian crimea from russian territory. in one thousand nine hundred three during world war two the most terrible battles shook this region. ships around the same time. the members have only four days to explore the ship's. boat sunk in the summer of one thousand nine hundred three.

according to satellite imaging the boat is not far from the shore and is at a considerably shallow depth. however the divers are not expecting much from the first dish even knowing its exact location they doubt they'll find a boat in the opaque waters of the black sea. but if i go. first stream diver erin one tank will be sufficient for two hours according to the schedule the initial dive is not to last more than forty minutes but the four divers spend about an hour under the surface when they come up the reason for the delay becomes apparent they found their boat if. it.

was there we saw the gun turret the this tool is this thick there is a part of the gun tower in the machine gun. will write down a description in a minute for. at the same time several thousand kilometers to the east another expedition is setting off from the bank of the world's deepest freshwater lake lake baikal all. the people on this barge floating on a huge lake is the same as being in outer space they think of themselves as astronauts of the aquatic world and their deep sea submersibles look much like spacecraft. mir one or two machines designed during the soviet period back in the one nine hundred eighty s. these water craft can dive to a depth of six thousand meters however they won't need to reach the dead keep them by call as the deep. parts of the lake are within one and

a half kilometers the surface. mia two depths fourteen hundred fifteen minutes is at the bottom. motorboat to near one finish taking samples begin the baling. it's the third expedition of the submarines in my call within two months the hydra nuts plan to perform many experiments during dozens of individual dives. which with us move abroad this time we will perform very accurate exploration in order to make a water analysis chart find out the chemical composition of the sediment and to finish research on the geology old league by call of. good work on the sofa we go. to let the expedition begin.

five men a dog and then both always does the old for travelling the expedition starts in st petersburg their destination the russian river volkov. just where sail into the river of old cove. as one of there is where we try to trick the old water routes in olden times the majority of trips where. as predicament ends you sail over the sea and to the mouth of a river and then head upstream to a certain city. many boats stayed in a permanent moring along st petersburg's in bank minutes many ships were turned into restaurants but the explorers are not interested in these boats they're attracted by untouched history such as the sunken vessels. found by the sea you experienced the strongest emotion is when you dive in finding you don't. and see things nobody would expect.

there are many ships in the gulf of finland having seen any by me. the next day the expedition heads across lake la to go to the river. it's an old russian waterway and a real paradise for underwater explores. the google routes were used in a trade. to use a different circumstances. when the ship sinks it stays at the river. and ends up being slowly come over the sand and silt. if you try to find the old ships. and how they worked. plus thirty here is you have to dress as if you were the north pole. it's like

a skiing outfit. joke five on the right. members of the expedition start their work early in the morning. drop sanker above the place they believe a merchant ship was sunk. a few brief instructions before the dive this sunken target sits in relatively shallow water and they'll be able to evaluate what state it's in the people it lays along and it's rather big. so you can move along the flow a bit deeper oh maybe closer to the shore and simply move forward i think you'll find the ship there. i'm ready. the first dive last for half an hour but it's not as easy as they thought the visibility is poor and the diver has to disappoint his colleagues.

it's the same. their colleagues. clearly showing. after the first successful dive. head of the expedition plan on how to lift a fragment of the boat.

the first day of the expedition comes to an end. around. the sure is related to research to a soviet squadron was here in one thousand nine hundred three. well the divers normally go underwater tonight they're going underground a long time ago soldiers would go through these dark damp corridors they bring shells here and take the wounded to a safe place quite often members of the expedition do things unrelated to underwater research their own a cable ducts and this must be an emergency exit for fifteen years businessman alex has been funding expeditions to the black sea in search of sunken ships. i was born in ukraine. and as a child i used to dive with a mask and

a snorkel looking for sunken ships. and world war two landing craft. that's how i got interested in it. but well it's on the yoke and makes it back to dive in the black sea only once a year. i can't live without the sea he started diving when the first appeared in the soviet era initially he was interested in the traces of ancient greek settlements not artifacts of war. you know. you know i once found a well under water but. there was a lot of anxious to go on for as scattered around it would go. on and when i took one of them out one would know i wanted to show it to everybody right away that they don't know that i had a straight from the surface and jumped out of the water where they are in my hands

the. decision day of the mir expedition starts with some routine work that i'm not a lot of but this is our laboratory where we store our samples in refrigerators. there are some freezers assortment of tables and other things little boards because of the living quarters and here is the toilets. and this is where we sleep an expedition just came in they're making themselves at home but. illegally stall from the buy call research institute will be our guide today he's probably the most anxious one waiting for the exhibition to begin only near submersibles are capable of reaching the depths needed to confirm his theory of how gas hydrates are formed some called these unique deep water compounds of water and methane the fuel of the future. these will be no we're going to the lake is four hundred meters deep in this about the gas hydrates become unstable above this level we want to use this

gas to hydrate on the surface that we're going to recorded on video to measure the temperature that they do in the middle of the. mirrors are capable of remaining underwater for up to two days working on their own i nag is planning to spend at least eight hours looking for gas hydrates this scientists opportunities are limited as each dive cost several thousand dollars the next opportunity to see the bottom of the lake probably won't come any time soon. for years committees are comfortable shuttle buses will take you to the spot. just

a few hours i'm certain urging forest and scaring to scorn. in your direction. on the move. crater. scorching soil. are included. with the wild lunar rover for free. though so many years of past some the former prisoners. are still a lot. as well this is for sure. those so many years of. summer hoping to find their saves. others take their executioners longing for justice. though so

many years of past and memory is still alive as well as home. if. soon from finest impressions. members of the expedition have a lot to do by themselves including cooking. to make this stage we will need

a lot of a few carrots. is usually made with us we have none so we just use poultry. meanwhile the senior researcher is trying to figure out when the ship they're studying was built. is a russian ship the construction technique is russian weekend in term and it's age as of now let's just say it was built in the eighteenth century. however as the first dive shows detailed inspection could be a problem strong currents and murky waters make it hard to get a good look at the ship the divers maneuvers itself in position to drop anchor right above the ship. which is ready you can. maybe some extra large portions so right here i go.

him out later he won't make it on his own but such a weight. an expedition of sunken ships is no punishment for these divers it's a vacation professional divers get their money from doing different kinds of work they spend most of their year studying the bottom of the baltic sea where russia is currently building a valuable gas pipeline. is more difficult and the schedule is far tighter. person usually visual association you know that if a man finds himself lost in the forest or. any other place that has no clear landmarks starts going around in circles. one leg is always stronger than the other one i have experienced this myself and it's the same on one leg kick stronger than the other one. four meters below the surface.

covered in. the ship is barely visible. over an hour underwater every minute he's at risk of being in tangled in the ship's fishing tackle. if. ever a ship has them but when there are many there in the vocal river. and i'm up for decades. from the nets end up lost so they call into boats and are dragged across the bottom and if you look at some ships you'll see that there are clumps of nets stuck to him and you have to be very careful not to get cold when visibility is this bad the worst thing is to get. in that case you will have to reach around your back to. the diver friendly comes to the surface he was successful this time and

the ship can be identified. here are the rods nails. the quality the iron is clear without corrosion points to the rather great age of the ship. sundries favorite design. this ship is loaded up with slabs of limestone the most valuable local community. doesn't have is. it four hundred meters deep depression is forty times as great as that on the surface. down here. and the only light source. is separated from the hostile environment by a thick layer of extra durable. glass i've we have selected several samples the main thing is that we have found gas hydrates at the slope of the bed deposits i've

the second finding out by town i. got lucky it turned out that the barge from which the mirrors were lowered stopped right above the place where these unique chemical compounds. vessels mechanical arms begin to collect samples of ground and water. from the depths at happy minute. gives us a finding we were also looking at this time found the second point where gas hydrates are at the surface and. that's probably what crews felt like when they simmers in the atlantic ocean to shoot footage eventually shown around the world. on a dive to the ocean floor by the mir vessels searchlights revealed the name of a sunken ship the titanic. was among the remotely controlled vessels during the dive to the titanic. this

particular ship famous footage became part of the film that won eleven academy awards. james cameron i can say he was easy to work with of course it was a pleasure to work with him but i know that every time he comes. up with mint and the missions are always complicated there's. rumors about james cameron coming to lake baikal have been circulating ever since the expedition began not everyone believed a famous director would make the dives but mr cameron couldn't turn down an invitation from. each the two had worked together on titanic. well it was very calm creative even. we had a rendezvous with mir two at the bottom we move smoothly in silence.

james cameron celebrated his fifty sixth birthday right before taking the plunge when he resurfaced he called it one of the most remarkable experiences he's ever had. this completely unique situation deepest freshwater lake in the world it felt like being at the bottom of the ocean. this in petersburg divers expedition on the river is about to conclude they found several sunken russian barges over a five day period using sonar to go in. a sand bank. i'm sure will run into a ship since countless numbers of them well you have sunk here over a thousand years. if you can see the shoreline here.

and this silhouette is probably a ship with one of. our vessels will soon turn around and then we'll try inspecting it again. but still they can't manage to get a good look at the ships. it's hard to. put it on the table but wait. that's colored and that's. the visibility is only twenty centimeters down there so you crawl around constantly getting caught up on the net with. the divers in crew still consider the expedition a success their main objective of finding the sunken ships and charting them on maps has been completed. meanwhile on the shores of the black sea somebody.

is nearing its end the tenting will be gone tomorrow but there's still time for one last dive to the submerged ship. a ship. is located seven meters from the surface it's the gun turret of a sunken armored ship it's a dream he can touch. to bring to dry land this time. with i think if you can go i think through ten days to spend here were quite fruitful of . course we couldn't bring up deterrents but i think next year will be better. than.

the expedition traditionally ends with the seaside picnic stories of ship wrecks are told along with several exciting tales and bell merely running out of oxygen to morrow these tents will disappear from the coast of the current strait. the hum of compressors pushing oxygen. into cylinders who fall silent and nobody will see the wreckage of ships hidden in a massive money water intil next year. wealthy british.
