Longer stays in an underwater station require systems to filter out Carbon Dioxide (CO2) from the air that is exhaled by the aquanauts. These CO2 scrubbers generally consist of a fan that pulls air through a canister filled with Carbon Dioxide (CO2) adsorbent, such as Sodasorb or Sodalime. To get a rough idea about CO2 scrubbers and their prices visit the webpage of AMRON International.
Keeping an air filled structure on the sea-floor is more difficult than one would think. Especially during the lowering process major difficulties occurred on previous stations. We can calculate about one kilo of weight (negative buoyancy) per liter of air inside the station (positive buoyancy). The dimensions are huge: imagine a space of 50 m² with a height of 2m, which equals 100 tons of counterweight. At the same time it has to be considered, that these weights have to be lifted again in the end of the mission. For ecological reasons we should find a way to leave the weights on the site and to use a material that would not harm the environment.

Seven miles deep, the ocean is still a noisy place. NOAA and partners bring back first recordings from deepest part of the world’s ocean. For what may be the first time, NOAA and partner scientists eavesdropped on the deepest part of the world’s ocean and instead of finding a sea of silence, discovered a cacophony of sounds both natural and caused by humans.
