(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”

HUNUC (abbreviation for Habitat of the University of Natal Underwater Club) was South Africas first underwater laboratory. However, the facility was destroyed shortly after its positioning due to conceptual errors and bad weather conditions. Continue reading “HUNUC”
(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 theCalamar Park modules.Continue reading “Breathing Gas Processing: Overview”
In 2016 deep sea technology developer Dr. Phil Nuytten had a TEDx speech about his vision of an underwater habitat called Vent Base Alpha. It would generate the necessary energy from the geothermal vent next to its location and would consist of a 1bar environment. (Video length 19:08 min.)
The danger of excursion divers getting lost have always been a major concern in underwater habitats. According to their webpage the Dive Tracker consists of a sender and a tracker. From a distance of up to 4000ft (≈1300m) divers can easily track the direction of the sender’s signal and return to their safe location. Costs: from 1200USD per set. (Homepage Dive Tracker).
(Updated 24.05.2018; added wet room configuration, scuba tank refilling installations and summarizing requirements list) 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.

BIOSMHARS was a 2-year (2011-2013) research project co-funded by the European Commission under FP7. It was the first phase of a joint EU-Russia research effort to develop the scientific and technical tools for a comprehensive approach to the challenging issue of biocontamination inside manned spacecrafts.

Update 27.04.2018: added new renderings) So 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”
(For English please scroll down) (Update 17.01.) Nachdem wir uns mit Dr. Jim Miller und Ian Koblick auf eine Übersetzung ihres Buches ‘Living and Working in the Sea’ ins Deutsche und insbesondere vom anglo-amerikanischen ins metrische Maßsystem geeinigt haben, können wir nun bekanntgeben, dass die Übersetzung inzwischen abgeschlossen ist. Momentan arbeiten wir an der Durchsicht und hoffen, in Kürze die Veröffentlichung beginnen zu können. Mit letzterem ist innerhalb der nächsten zwei Monate zu rechnen.

For working and relaxing on deck we created this deck-shirt. We noticed that after a dive you are often shivering, while staying in the sun leads to a sunburn and the shade might be to cool. We needed a shirt that protects partially from the sun and its reflection from the water surface without keeping the summer heat in it, and still leaves the wind through its textile. We also wanted to cover our head without to be forced to wear a cap, that heats up even more and is easily forgotten on the boat. Continue reading “CalamarPark Deck-Shirt”
(Updated 07.06.2017; added crowdfunding, daily turnover by educational institutions and underwater archaeology) 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. It was a very exciting period having the facility on risk. It took until January 2013 when a proposal to keep Aquarius running under Florida International University administration was accepted. What could we do in future projects to avoid sooner or later close-downs by lacks of financing? Continue reading “Financing an undersea station”
(Updated 04 April, 2017) In our undersea station one of the ways to absorb Carbon dioxide from the air and to produce oxygen instead might be beside classic scrubbers the Biocoil reactor that was first introduced by a science class of Cascade High School in the US. It looks like a quiet simple system based on Chlorella algae and it was used in Lloyd Godson’s ‘BioSub’ project in 2007.

Updated 06.03.2017 – 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.

The FlyDive is a transportation system for divers and a brainchild of Christoph Schindler. The Propulsion for this device is generated by pressurized air moving a pair of flexible wings imitating the body of a ray. Continue reading “FlyDive by Schindler Design”
Here is an idea for a porthole where the structure of the underwater station does not allow to install one. For example on the ceiling, where penetrations of the shell should be strictly avoided in order to maintain the integrity of the emergency safety area in the upper part of the living area. The Virtual Porthole would consist of a camera on the exterior of the shell and a TV flat screen on same position inside the habitat. Continue reading “Underwater Station: Virtual Porthole”
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.
