Habitat Entrance

Moonpool of Hydrolab

(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.

Undersea Station: Data Processing

Calamar Park UI(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.

Undersea Station: Water Supply

Water Supply: Image by James Petts from London, England (Stream of water) [CC BY-SA 2.0 (http://creativecommons.org/licenses/by-sa/2.0)], via Wikimedia Commons(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?

Branch & Bound

(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”

Underwater Navigation

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).

Leben und Arbeiten im Meer

(For English please scroll down) Zur Erinnerung: Ich hatte mich mit Dr. Jim Miller und Ian Koblick auf eine Übersetzung ihres Buches ‘Living and Working in the Sea’ (‘Leben und Arbeiten im Meer‘) ins Deutsche und insbesondere vom anglo-amerikanischen ins metrische Maßsystem geeinigt. Die Übersetzung und erste Durchsicht ist abgeschlossen und alle notwendigen Kontakte geknüpft. Der ursprüngliche Plan, die Veröffentlichung über Crowdfunding zu finanzieren, hat jedoch einen Dämpfer erhalten, weil alle Crowdfunding-Plattformen Projekte aus dem Land, in dem ich seit langer Zeit lebe, nicht akzeptiert. Ich brauche da also eine andere Lösung. Continue reading “Leben und Arbeiten im Meer”

Living and Working in the Sea

Living and Working in the Sea(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.

Wireless Sensor Network (WSN)

Control Panel in UWL HelgolandSeveral years ago Benjamin proposed a system of sensors inside the habitat measuring all necessary parameters like oxygen, carbon dioxide etc. and communicating among each other. Last days we talked about it again and found out, that it would still be a good solution. So we decided to publish it here again. Below you find the original thread, translated from German: Continue reading “Wireless Sensor Network (WSN)”
