The 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.
