Abstract : When dye is used as a marker for sea survival the compound is dispersed directly into the water by leaching from a small cloth bag that is tied to the raft or life preserver. If the survivor is not seen and rescued after a short lapse of time, the dye becomes so dispersed it is rendered invisible. A solution is to make better use of the quantity of dye provided in survival kits. The use of very thin plastic bags suggested itself as a means of dispersing and confining the dye in such a manner that it not only would be seen but would remain visible for a longer period of time. Experiments were performed on a laboratory scale in which very small quantities of dye were dispersed both in water and in small plastic bags containing an amount of water sufficient to dissolve the dye yet not enough to cause the bag to sink. It was found that wheras the dye dissolved in the water become completely dispersed and invisible, the dye in the bag remained concentrated and visible as long as the bag remained afloat. (Author)
