Meeting on Habitability & Marketing

It was great to have Alison Mattos, Alan Allen, Brendon Traxler, Nursel Arslan and Martin Henke on a discussion about Habitability and Marketing of undersea habitats on 23rd June. We had very interesting first hand insights of Hydrolab and Jules Undersea Lodge and look forward to the next session. Thanks everybody for joining.

Escape to the Seafloor

“It was probably in 7th or 8th grade; I didn’t quite catch the teacher’s question to all of us, but it was probably about what would happen if the fishery went on as before. I only regained consciousness from my daydreams when I was called upon to answer the question. I hesitated and said, that at some point there might be no more fish, the sea would be almost completely fished out. The class burst out laughing and the teacher, clearly amused, reassured me, that could take a while. Continue reading “Escape to the Seafloor”


After collecting more than 140 proposals for habitability from several different sources like astronauts, space analog missions, aquanauts, hydrophilic design and our own simulations, we are probably able to implement 136 of them into our ‘Hangar II’ design. It is unlikely that this number decreases with more detailed planning. All proposals received a registration number to be tracked in the planning process with their sources and remarks.

Managing Partnership

Happy to announce that CalamarPark is now a branch of Cabrito Consulting in Germany. Thus we finally have the legal infrastructure to join partnerships and apply for funding to various sources. This step has been requested several times to start any cooperation and we are now able to respond those calls.


The moonpool of habitat Hydrolab(10.06.2021) Happy about the agreement with Peter Weiss and Spartan Space to develop a mobile habitat for interdisciplinary applications as part of the Mediterranean Undersea Research Station. Emphasis will be on compatibility with future modules.

For several years Peter was member of the executive board of COMEX, manager of R&D and industrial projects in the field of space technology, subsea engineering & robotics and marine renewables, leader of the Diving Support team at the European Astronaut Centre EAC. His new company Spartan Space concentrates on manned habitats for space and underwater applications.

Initial Funding

(updated 12.04.2021) We have initial funding for the next development phase of the CalamarPark underwater habitat. Thank you Frank Scharmann, CEO of Cabrito Consulting and welcome to the team.

Undersea Station: Data Processing

(Updated 15.01.2021 – complete re-edit of post; updated concept map) 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.


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).
