A reef aquarium or reef tank is a marine aquarium that prominently displays live corals and other marine invertebrates as well as fish that play a role in maintaining the tropical coral reef environment.

Model of Emma Mærsk undergoing testing in a ship model basin. A ship model basin is a basin or tank used to carry out hydrodynamic tests with ship models, for the purpose of designing a new (full sized) ship, or refining the design of a ship to improve the ship's performance at sea. It can also refer to the organization (often a company) that ...
Figure3: Typical batch-settling column test on a suspension exhibiting zone-settling characteristics. The settling particles can contact each other and arise when approaching the floor of the sedimentation tanks at very high particle concentration. So that further settling will only occur in adjust matrix as the sedimentation rate decreasing.
A saltwater aquarium is an exotic and striking addition to the home. But more than a striking piece of furniture, it’s a living habitat that is both enthralling and engaging thanks to the ...
Testing water in the Gulf of Mexico after the Deepwater Horizon oil spill After events such as earthquakes and tsunamis , there is an immediate response by the aid agencies as relief operations get underway to try and restore basic infrastructure and provide the basic fundamental items that are necessary for survival and subsequent recovery.

Live rock is highly valued in the aquarium trade. It introduces a diverse array of bacteria, algae, and invertebrates to the closed marine environment and functions as a superior biological filter that hosts aerobic and anaerobic nitrifying bacteria required for the nitrogen cycle that processes waste.
The lost buoyancy of the tank results in that section of the ship lowering into the water slightly. This creates a list unless the tank is on the centerline of the vessel. In stability calculations, when a tank is filled, its contents are assumed to be lost and replaced by seawater.
