An apparatus that facilitates search and rescue, for example, in open water. The apparatus comprises a substrate with a particular geometry and a perimeter. The apparatus further comprises a cover positioned atop the substrate with the cover also having a particular geometry and perimeter, which correspond to the geometry and perimeter of the substrate. An air-tight seal seals the substrate perimeter to the cover perimeter and creates a sealed internal region. A liquid-releasable vessel holding an illuminable dye located in the sealed internal region, along with an activator that is also located in the sealed internal region. When the liquid-releasable vessel releases the illuminable dye, the illuminable dye reacts with the activator, thereby resulting in illumination of the illuminable dye. The liquid-releasable vessel comprises an opening with a release mechanism (e.g., clamp, etc.).

A device that can provide sustained release of a detectable marker into a surrounding body of water as well as methods of forming the device and methods of using the device. The devices and methods can be utilized to locate people or vessels, e.g., by search and rescue personnel, following the disabling of air or water vessels of any type or size on/in a body of water. The devices include multiple, separated layers that each include a detectable marker, e.g., a fluorescent dye. The dye-containing layers are separated from one another and sequentially released over a predetermined controlled period of time and as such the device can continue to release a detectable marker over an extended period of time into surrounding water.

Systems, methods, and apparatus for the use of an emergency dye for search, rescue, and recovery is disclosed. In various embodiments, an emergency dye may comprise a high-visibility dye configured to reflect light in a visible light spectrum. The emergency dye may be configured to be disposed of on an aircraft. The emergency dye may be configured to be disposed of within an emergency dye package. The emergency dye may also be configured to be disposed of within an aircraft's hydraulic system. The emergency dye may be configured to be released from the aircraft, based on monitoring an aircraft's avionics system for an imminent crash alert.
