A type of single use underwater lighting source that was in limited use during the 1950s is the magnesium torch, a pyrotechnic device using magnesium metal that could be ignited and would burn underwater. It produced a bright white all-round light, and once activated would continue to burn until exhausted.
Ocean optics is the study of how light interacts with water and the materials in water. Although research often focuses on the sea, the field broadly includes rivers, lakes, inland waters, coastal waters, and large ocean basins. How light acts in water is critical to how ecosystems function underwater.
Active systems are often using a wearable on the swimmer, such as a wristband, that monitors the behaviour and position of the swimmer. If the swimmer is detected to be under water för a certain period, an alarm is triggered and through acoustic underwater communication from the wristband to receivers installed in the pool the alarm is transferred to on-site lifeguards that immediately can ...
A magnesium torch is a bright light source made from magnesium, which can burn underwater and in all weather conditions. They are used for emergency illumination for railroad applications. They were also used in the 1950s up to the early 1970s as a light source for scuba diving, and were featured occasionally in television shows. A relay of ...
Underwater habitats are designed to operate in two fundamental modes. Open to ambient pressure via a moon pool, meaning the air pressure inside the habitat equals underwater pressure at the same level, such as SEALAB. This makes entry and exit easy as there is no physical barrier other than the moon pool water surface.
An infinity pool [note 1] is a reflecting pool or swimming pool where the water flows over one or more edges, producing a visual effect of water with no boundary. Such pools are often designed so that the edge appears to merge with a larger body of water such as the ocean, or with the sky, and may overlook locations such as natural landscapes ...
