Silfra on Iceland is the only place where you can dive or snorkel directly in the crack between the two continental plates of North America and Europe. Visit dive.is for more.
Keeping an air filled structure on the sea-floor is more difficult than expected. Especially while descending and landing the station major difficulties occurred on previous stations. We can calculate about one kilo of weight (negative buoyancy) per litre of air inside the station (positive buoyancy). The dimensions are huge: imagine a space of 50 m² with a height of 2m, which equals 100 tons of counterweight. At the same time it has to be considered, that these weights have to be lifted again in the end of the mission. For ecological reasons we should find a way to leave the weights on the site and to use a material that would not harm the environment. Continue reading “Undersea Station: Ballast”
Australian based Carnegie Wave Energy and their Ceto Wave Energy System uses buoys and pumps to convert ocean waves into renewable energy and fresh drinking water. Watch it on Huffington Post
Seven miles deep, the ocean is still a noisy place. NOAA and partners bring back first recordings from deepest part of the world’s ocean. For what may be the first time, NOAA and partner scientists eavesdropped on the deepest part of the world’s ocean and instead of finding a sea of silence, discovered a cacophony of sounds both natural and caused by humans.

How the Lion City was purposely-flooded to make way for a power station but remains completely intact 40m underwater after 50 years. Read more on dailymail.co.uk with many fascinating images and videos.
If you always wondered how the biggest ever built submarine, the russian Typhoon class interior looks like you should have a look at livejournal.com. It has designed for a crew of 160 marines and has a length of more than 170m. The images were taken 2009 and show the whole interior including sauna, pool and gym.
The development and research project “StEnSEA” (Stored Energy in the Sea) is investigating the installation of large storage facilities on the sea floor, in combination with offshore wind farms. The physical principle on which the energy storage facility operates is similar to that of conventional pumped storage power plants, but based not on two reservoirs, but a hollow sphere.

Neft Daşları is an industrial settlement in Baku, Azerbaijan. The settlement forms part of the municipality of Çilov-Neft Daşları in the Khazar raion. It lies 100 km (62 mi) away from the Azerbaijani capital Baku, and 55 km (34 mi) from the nearest shore in the Caspian Sea. A full town on the sea with up to 5000 inhabitants, it was the first oil platform in Azerbaijan, and the first operating offshore oil platform in the world, incorporating numerous drilling platforms.

One of the reasons why the first generation of underwater stations came to an end in the 80’s was the conlusion that it is more effective to use decompression chambers on board of a support vessel instead of placing divers on the bottom of the sea. The oil industry just did not see any reason for undersea stations. Therefore it was surprising that China announced in 2012 that they planned to build an undersea mining station of 60 meters length Continue reading “Chinese Underwater Station”
After UnderwaterPromotion.com was fataly hacked we asked ourselves if we should use the opportunity to restart completely and get rid of the ‘Promotion’ that caused too much trouble in the net. So we came to ‘Calamar Park‘ with emphasis on investigation and development for a life under the sea. Well, let’s see where the rabbit hole goes.
