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).

Habitat Entrance

The moonpool of habitat Hydrolab
Moonpool of Hydrolab

(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

Bacteria isolated in dairy product (representative image)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.

Undersea Station Draft No.4: Hangar

Undersea Station Draft No.4; Module 1; overview
Module 1; overview (preliminary rendering; V26-04-2018)

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”

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.

Breathing Gas Processing: Overview

Breathing Gas ProcessingUpdated 13.08.2017 (added chapter ‘sources’)

Living in an underwater habitat requires gas treatment; an input of oxygen, the disposal of carbon dioxide and pollutants, and one kind of ‘carrier’ or inert gas (nitrogen or helium). Industrial divers live in a pressure complex on a support vessel and all air treating is done outside the habitat on the vessel. It seems there are not too many references of air being treated inside an underwater habitat. If we are mistaken do not hesitate to comment this article accordingly.

CalamarPark Deck-Shirt

The CalamarPark Deck-ShirtFor 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”

Financing an undersea station

financing an undersea station

(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”

Undersea Station: Biocoil

Lloyd Godson and the Biocoil(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.

Underwater Station: Virtual Porthole

Virtual Porthole inside the Underwater StationHere 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”

The UW Station Forum (2007-2012)

forum-logoThe 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.

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”
