Scuba Education Book For Children

aquanautica-krakiAs 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”

Plants Clean Air and Water for Indoor Environments

Osmunda Regalis, Christian Fischer [CC BY-SA 3.0 (http://creativecommons.org/licenses/by-sa/3.0)],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:

Tektite Habitat on Wikipedia

OAR/National Undersea Research Program (NURP)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.

Kemer Underwater Guide

UW Guide KemerIn 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”

Diving Bell ‘Medusa’

© CalamarPark.comTogether 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’”

Nemo’s Garden Project by OCEAN REEF

Portulaca_sativa_01 © Wikimedia Commons, User: BurschikGrowing 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?

‘Project Undersea Station’ Introduction

Wordpress Header(Updated 06.07.2016) PROJECT UNDERSEA STATION aims the development of a new generation of undersea settlements. Technically based on experiences of prior stations there will be several new considerations concerning expandability, size and usage. All results will be open-source (except some marketing details necessary for continuous popularity) and anybody who is interested has the chance to contribute his ideas. Until the minimum financial frame is completed we will go on collecting as many information as possible, implement them to a realistic blueprint and constantly improve the final design. Ultimately the final goal is the actual building of the habitat. Continue reading “‘Project Undersea Station’ Introduction”

CO2 Scrubber

Amron International, CO2 ScrubberLonger 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.

Undersea Station Draft No.4: Hangar

© CalamarPark.comSo far the final draft follows the hangar shape. Having a look at the evaluation list in the ‘Structural Shape‘ chapter it seems like the ideal shape for the undersea station.

Because of the sand used as variable ballast and the space under the station the structure is easily removable by just releasing the sand. No harmful materials or items would be left behind which serves the ecological idea. Continue reading “Undersea Station Draft No.4: Hangar”

Undersea Station: Operational Depth

© CalamarPark.comThe operational depth of the station correlates with the targeted type of users and the desired decompression schedule. Let’s start from the extreme:

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”

Undersea Station: Event Plan

IWM Theme Park AnchorOne of the differences to other previous stations is the fact that it is not only available for a small group of scientists, but to a large group even of private participants. Of course, it still requires a very strict program to enter the station. The idea is to settle the station inside a park (The Calamar-Park) and make it available for all sport divers. For this touristic purpose a row of activities and attractions has to be designed. These attractions will follow a chronological program to maintain continuous popularity. That means that when an attraction reaches its half-time period another attraction should be already on its way as seen in the following graph: Continue reading “Undersea Station: Event Plan”

Undersea Station Draft No. 3: Sphere

banner 2016 web

Source: WikimediaFor a long time we favoured the shape of a sphere mainly because there were ready structures available used as pressure resistant LPG tanks. It would have measured 12m in diameter, the lower half would be filled with sand just before lowering while the upper half would contain two floors of living space. After discussing the idea with different engineers we had to accept that a LPG tank would need so many modifications that building a new one would be even cheaper. After receiving the first cost estimations we were pretty sure that it would be impossible to find funding for a civil structure of that scale.

Undersea Station: Ballast

ballast-experimentKeeping an air filled structure on the sea-floor is more difficult than expected. Especially while descending and landing the station major difficulties occurred on previous stations. We can calculate about one kilo of weight (negative buoyancy) per litre 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. Continue reading “Undersea Station: Ballast”
