Ocean location marking using film forming polymers |
| abstract |
A method of and an apparatus for providing an all weather day and night ltion marker on the surface of a body of water enable optional visual, radar and IR detection to ensure the timely rescue of a disaster victim. A cohesive surfactant is mixed with an evaporation reducer and contained in a packet that allows the dispersing of a film made up of the two compounds after they are placed in the water. The film creates a surface that has a slick appearance with respect to the surrounding water, that has a reduced radar backscatter with respect to the surrounding water and which, as a result of reduced evaporative cooling, results in a local increase in the surface temperature with respect to the surrounding water to assure the visual, radar and IR detection. |
