(Updated 04.07.2020; added new visualizations; minor additions/corrections to access tunnel) Surely one of the most complicated area of an underwater structure for human occupation is the habitat entrance. It is the local water-air interface, vulnerable to changes in pressure by tidal movements on the surface of the sea; its hatches have to bare potential pressure differences between the habitat interior and the surrounding water; no object that is only a little bigger than the greatest diameter of the entrance can be brought into the habitat. It is constantly wet and humid and the only gateway for medical assistance. But to see in detail let’s have a look at the different sections of the entrance complex.

(Updated 01.06.2020: complete edit of the article) Lighting in the main habitat will consist of different modes: standby, activity, emergency and disinfection. This section should explain the ideal system of lighting inside the underwater habitat. Continue reading “Interior Lighting”
(update 31.05.2020: integrated article ‘event plan’; adding section ‘science (general)’, entertainment, space agencies; extended ad section; article under progress!)

The most professional underwater habitat so far is still the Aquarius habitat in Florida. This quality comes to a certain price of $1.2 to $3 million per year. Due to budget cuts, NOAA ceased funding Aquarius habitat after September 2012, with no further missions scheduled after a July 2012 mission, bringing the whole facility under risk. It took until January 2013 when a proposal to keep Aquarius running under Florida International University administration was accepted. What can we learn for future habitats and what could we do then to avoid sooner or later close-downs by lacks of financing? Continue reading “Undersea Station: Operational Financing”
(Updated 11.06.2020; added new sectors of potential financers, like tourism, environmental protection etc.)

In the past years we have seen that it is very difficult to attract investors for the initial building of even a small habitat. In the beginning we concentrated on scientific institutions who always were very interested, but not able to lift the initial costs. Before we start to calculate the initial costs we should define the sectors of potential application, rethink the habitat design to cover the demands of as many of these sectors and then refine the initial costs.

(Updated 15.05.2020 – Added noise recognition to Concept Map, improved article structure etc.) The Digital Data Processing of the station will be of major importance. Beside the conventional functions of the IT systems we should use the opportunity to establish a completely new approach concerning the User Interface (UI) and the system’s interaction with the aquanauts. Continue reading “Undersea Station: Data Processing”
(Updated 16.03.2020: added mast, camera, number of devices and additional data line) Solar power and an undersea habitat does not seem to fit each other. But in 2012 I had the idea of a device that opens its harvesters only if the conditions are appropriate just like a hibiscus blossom at dawn. I called it a Solar Lily. Continue reading “Solar Lily to power undersea station”
(Updated 09.02.2020: link concerning average need of water for a human being updated) 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”
To build an underwater habitat we have to know the measurements of human abilities, his limiting values and restrictions. In 2010 NASA published the Human Integration Design Handbook which gives answers to most of these questions. Though it is meant for space flight we can easily adapt most of it to an underwater application. The handbook is available as *.pdf on the server of our digital library. Contact Mart for access.
(Guest article by user Mike, thanks for contributing) By common definition, Branch & Bound is a mathematical algorithm to solve integer optimization problems. But simplified versions of Branch & Bound are also applied to find best fitting technical solutions manually. It is a useful tool for making fundamental decisions, such as the selection of a synthesis route during the project development of a new chemical factory complex.
In the context of CalamarPark, the design of the underwater habitat is such a fundamental decision: Should it be small or large? To operate at what depth? Ambient or atmospheric pressure? A certain design might be perfect at one location, but only second choice at another. Continue reading “Branch & Bound”
(Update 29.08.2018: Added water air membrane; oxygen by electrolysis. Dieser Artikel steht unter “Atemgas” auch auf Deutsch zur Verfügung) This article is intended to define the concept for ensuring the appropriate habitat atmosphere to be used in the Calamar Park modules.
