install a hydro-acoustic monitong station in one of the most remote places on earth-- the ocean floor halfway between africa and antarctica. when completed, hydro-acoustic station number 4 at the crozet islands will join the ctbto international monitoring system to detecand alert the world of nuclear testing. jerry stanley: installing a hydro-acoustic station is a complex social engineering task. the hydro-acoustic system we're installing at crozet is one of 6 hydro-acoustic stations. but these hydro-acoustic stations are part of the international monitoring system, which has over 300 stations listening for potential nuclear tests around the globe. man: 10... narrator: we proceed to develop moreaccuratend destructive nulear weapons. over 2,000 nuclear bombs were detonatein

he last half of the 20th cenry. [explosion] but in 1996, the global community said "enough" and signed the united nations comprehensive nuclear test ban treaty. today, 183 countries have voluntarily agreed to stop nuclear testing. but while signed in good faith, the mission of the ctbto is to verify the treaty's compliance with hard data. stanley: we're moving towards the final stages now of installing the hao4 station, but we were working in the roaring forties, so the weather can be very unpredictable. mario zampolli: those places, the roaring forties, are legendary among sailors and people who work at sea as some as some of the most difficult oceans in the world. you have what is called an unlimited fetch,
12:35 am
currents that are also merging, coming down from south africa, merging with certain polar currents, that go all around the world, really undisturbed. in these difficult conditions was really something that put a lot of stress on everybody, on all the teams. you know that you're not afforded, you're not allowed many mistakes. patrick grenard: of course it's not only a harsh environment above the sea surface, it's also a harsh environment underwater. but we knew that we had a mission to accomplish. it was to install that station despite the difficulties, despite th harsh environment, the complexity of the project, we had to do it.

man: once we get going, we can adjust it, ok? narrator: after more than 4 years of meticulous planning, two triplets of underwater microphones called hydrophones are finally loaded onto a specialized cable ship. stanley: we have to be very careful loading our system on. we have a lot of cables connecting the system together, and there's also some delicate electronics, the laser systems, et cetera. we have specialist crane operators and 10 people-- 10 people-plus supporting the loading. man: [indistinct] stanley: and then we transit to the cable factory in port smith. narrator: it will take 3 days to load 120 kilometers of

underwater cable...and another 5 weeks to reach the crozet islands in the south indian ocean. [man speaking french] [penguins squawking] [daniel fouquet speaking french]

[fouquet speaking french] zampolli: several experts advised us that a good time to be there would be between december and february. however, it turns out that december was just apparently one of the worst ones they've ever had on record. man: whoa. zampolli: what was happening there was that there were these systems brewing up south of south africa and being launched by the winter waters like frisbees. freezing cold hurricanes, with snow, hail, anthe wind startso be about more than 100 miles an hour, you have to go down and walk on all fours and work your way up, because dinner is up at the base. [laughs]
12:39 am
narrator: brief baks between passing storms allow just enough time to deploy t hydrophon to the sea for. when a syems are go, the ship releases the orange floats from thr anchors,ifting the underwater microphones to their intended depths. zampolli: and then... bang--you see these things arrive and then you start finally seeing data. you start hearing whales, you start... you suddenly have eyes underwater. narrator: from the indian ocean down to the arctic sea, from the atlantic to the pacific, hydro-acoustic station number 4 at the crozet islands is now online, relaying data in real time to ctbto headquarters in vienna. the data is analyzed and shared with its test ban treaty member states almost as fast as it comes in. with 90% of its entire

international monitoring system in place and its capability to monitor the world's oceans complete, the ctbto can detect and alert the world to any potential nuclear test anywhere on the planet, 24-7, 365 a year. [indistinct] [rumbling]
