Beschreibungen/Notizen

• Monofilament nylon line can be made more or less visible when viewed in the sea or in green light in tanks by the use of coloured dye. The undyed line, although least visible when perpendicular to the sea surface, shows a bright jewel-like glint when parallel to it. There is also a bright glint in the knots of netting, being brightest where the line is oriented parallel to the sea surface. The glint changes from mainly a surface reflection in air to an internal glow when immersed in water due to a lengthening of the focal length of the nylon cylinder. However, because in the sea the glint is derived from green downwelling light that has passed into the nylon cylinder, it is reduced by pale dye colours that remove a proportion of the green light. This allows a controlled reduction of the glint and a closer match with the water background when viewed horizontally.
