To stay in an underwater habitat longer than 12 hours means to stay under saturated conditions, which requires an aquanaut decompression sequence of at least several hours. This decompression procedure is very critical: if any of aquanauts gets into an emergency situation, there is no way to take him out of the chamber before the sequence is finished. If the procedure is badly designed there is no way to bring a paramedic into the chamber. For the period of several hours the aquanaut would be alone with his companion.

Check out Wikipedia for all information about the history of Underwater Habitats. We just finished the preparation for the same article on the German Wikipedia and will continue to add the results of our investigations there.

Nachdem wir uns dazu entschieden haben, alle Studien über bisherige Unterwasserstationen in die deutschsprachige Wikipedia einzupflegen, ist nun der Artikel über Geschichte und Technik von Unterwasserstationen soweit abgeschlossen und dort online. In Zukunft werden noch weitere Infos hinzugefügt.
The Triton is a sort of artificial gill that would extract oxygen from the water for you in an on-demand fashion as you swim, obviating the need for bulky SCUBA gear. Is this really possible? Find the answer on Deep Sea News.
The subject of Interior Design attracted more than 16.000 readers in the Underwater Station Forum on UnderwaterPromotion.com. The contributions are summarized here: Continue reading “Undersea Station: Interior Design”
The first idea for an undersea station developed in 2007 with the opening of the Underwater Station Forum on UnderwaterPromotion.com. In the following 5 years we collected nearly 250 evaluated contributions on 34 subjects. Without counting all hits of bots and search engines we had more than 200.000 interested readers. The page might have been fatally hacked, but all these contributions were not lost. We distilled them and are still publishing the summaries on CalamarPark.com since 2016. Still it is an open-source project and we ask everyone interested in the subject to contribute his ideas and comments via the comment function under each post.
As an initiative of Dieter Heinz, former owner of IWM, we finished development of the Aquanautica in 2006. The educational book for children scuba courses in shallow waters has 27 pages and explains all details in a language that makes the complicated subjects easily understandable. All illustrations and layouts were made by Calamar-Park (or the former Underwater Promotion Office) while all contents were supervised and directed by Dieter Heinz who took a great part in developing children equipments for MARES/Italy.
The German version of the Aquanautica received wide appreciation by the CMAS (Confédération Mondiale des Activités Subaquatiques) and was officially recommended by the Federation of Diving Centers VIT (Verband Internationaler Tauchschulen). Continue reading “Scuba Education Book For Children”
Back in the late ‘80s, NASA was looking for ways to detoxify the air in its space stations. So it conducted a study to determine the most effective plants for filtering the air of toxic agents and converting carbon dioxide to oxygen.See more on GOOD Magazine. Or the corresponding pdf’s:

The Tektite habitat was an underwater laboratory which was the home to divers during Tektite I and II programs. The Tektite program was the first scientists-in-the-sea program sponsored nationally. The habitat capsule was placed in Great Lameshur Bay, Saint John, U.S. Virgin Islands in 1969 and again in 1970. Get all information on Wikipedia.
Ich hab’ alle auftreibbaren Informationen zum Habitat Tektite mit den MIssionen Tektite I (1969), Tektite II (1970) und Minitat auf Wikipedia zusammengetragen, wo sie hoffentlich bis in alle Ewigkeiten abrufbar bleiben. Hier geht’s zum Artikel.
Event though our station is surrounded by water we can not use it for most of our needs. Therefore for some demands we have to establish a sweet water supply. The easiest way is to bring sweet water from the shore and to fill corresponding tanks. Well, what kind of water do we need? Continue reading “Undersea Station: Water Supply”
As an initiative of IWM (International Watersports Management) we opened the Underwater Sculpture Exhibition Deep Art on 9th September 2005 in the bay of Kiriş 12m below sea level. Ergün Marble Industries financed the transportation from Eastern Anatolia to Antalya. Continue reading ““Deep Art” Underwater Sculptures”
In 2007 we completed the interactive underwater guide for Kemer/Turkey including the regions Antalya City, Beldibi, Göynük, Kemer, Kiriş, Çamyuva, Tekirova (incl. the Environmental Park ‘3 Islands’) and Adrasan. The project was sponsored by ANEX Tour and Club Magic Life and used on various fairs as a promotion tool for the scuba diving tourism. By being programmed in HTML the guide was compatible with all computer systems. Continue reading “Kemer Underwater Guide”
Together with the popular MARES Diving Center of IWM of Dieter Heinz in Antalya/Turkey we decided in 2006 to construct a simple diving bell for touristic purposes in a depth of appr. 9m. This diving bell would serve as an advertisement carrier, sales tool and later as a decompression stop bell if successfully positioned. It should last for at least two years being removed during six winter months. As a design we wanted the construction to follow the shape of a jelly fish and to look a bit futuristic. After agreeing and drawing the final design we calculated costs of 1000 € which included the umbrella, the skeleton, the counterweights and the working force. Continue reading “Diving Bell ‘Medusa’”
Growing plants in the undersea station will be very difficult. But the experiment below brought the following question to my mind: If the site of the station would be the Mediterranean, which is a subtropical environment, then the main season would be the summertime. During that period many crops would not grow due to sunlight intensity and heat. The project in the video might be an alternative to use the seawater as a light filter and cooling medium. Would it be worth to investigate?
Silfra on Iceland is the only place where you can dive or snorkel directly in the crack between the two continental plates of North America and Europe. Visit dive.is for more.
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.
50m and more (depth of Sealab III -189m, depth of Conshelf III -100m): This depth is highly complicated. The aquanauts are saturated and demand long decompression periods of several days after the dives. Therefore it is impossible to go and come back, but one dive (exposure) should last several days. The breathing mixture consists mostly of Helium which makes communication without unscramblers impossible. The handling of pure oxygen requires oxygen-clear equipment. The aquanauts have to pass a long training program. The environment is cold and dark. Depths like this might be a target for the future, but for the beginning and especially for the purpose to attract attention it is not first choice. All these obstacles occur at all depths of more than 60m. Continue reading “Undersea Station: Operational Depth”
