Habitat Entrance

(Updated 29.11.2020; re-edit of the hatches chapter) 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.

Housekeeping

Housekeeping in an underwater habitat is a crucial part of habitability. It plays a primary role in maintaining the cleanliness of the habitat and thus the crew’s health and safety, which will consequently boost their morale, comfort, and productivity. Continue reading “Housekeeping”

ESA Qualification

We are very happy that our proposal of an European Underwater Research Center has been qualified today by ESA to be presented for discussion and vote. So there is a realistic chance for funding of a detailed feasibility process leading to the construction of the first module(s).

Recreation

Scene from Aquarius Habitat(updated 15.09.2020: added adaptations from the NASA Human Integration Handbook) Recreation is an important consideration for maintaining high morale, psychological and physiological health in an underwater habitat, especially for long durations. This section provides guidelines for recreational activities.

Stowage & Inventory Management

This section discusses design considerations for the layout and design of stowage systems inside an underwater habitat. It also provides the characteristics of a successful onboard inventory management system design. Such a system can track the quantity, location, and status (e.g., remaining useful life) of inventory items. The inventory management function is one of the primary elements of onboard information management. Continue reading “Stowage & Inventory Management”

Nutrition

For long-term stays in an underwater station, a plan for ideal nutrition is required, which takes into account the special circumstances such as increased-pressure environments and reduced sunlight. This section will discuss the specific requirements and the resulting dietary recommendations, which include environmental considerations (avoidance of waste…), safety precautions (avoidance of contamination of the habitat atmosphere…) and alternative sources of supply (own production, finished products…). Some considerations will require a certain design of the corresponding habitat sections. Contact us for access to the whole article.
