If altitudes at sea could be measured with respect to the observer's vertical, the point directly over his head, which on land might be determined with an accurate plumb-bob or spirit-level, high accuracy could be obtained. Unfortunately, at sea the observer in a moving vessel has to measure altitudes with respect to the horizon. 1, record 2, English, - observer%27s%20vertical

Predominantly green colouration of short duration, often in the form of a flash, seen at the extreme upper edge of a luminary (Sun, Moon, or even a planet) when disappearing below or appearing above the horizon. 2, record 3, English, - green%20flash
Record number: 3, Textual support number: 1 CONT
When the sun sets, sometimes the last bit of light from the disk itself is an emerald green. The same is true of the first bit of light from the rising sun. This phenomenon is known as the "green flash" or "green ray". It is not an optical illusion. The green flash is common and will be visible any time the sun is rises or sets on a "clear", "unobstructed", and "low" horizon.... The explanation for the green flash is thus, 1) refraction separates the solar images by color; 2) at just the right instant, the red image has set, 3) the yellow image is absorbed; and 4) the blue image is scattered away. We are left with the upper limb of the green image. Because the green flash is primarily a refraction effect, it lasts longer and is easier to see from a mountain top than from sea level. 3, record 3, English, - green%20flash

Coloration à dominante verte et de courte durée, souvent sous forme d'un éclat bref, observée au moment ou l'extrême bord supérieur d'un astre (Soleil, Lune ou même une planète) disparaît derrière l'horizon ou apparaît au-dessus de l'horizon. 2, record 3, French, - rayon%20vert

Qu'est-ce que le rayon vert [...] juste avant le coucher du soleil, [...] ce fugace rayon vert émeraude [...] apparaît, et disparaît presque aussi soudainement, lorsque le bord supérieur du disque solaire effleure l'horizon juste avant de se coucher. Cette petite tache lumineuse dure à peine quelques secondes. Plus précisément, 1,8 sec à l'équateur, 2,5 sec à une latitude de 45 degrés. Ce phénomène de réfraction, qui ne se produit que lorsque l'atmosphère est extrêmement pure et qu'il y a très peu de particules pouvant créer de la diffraction ou dispersion, apparaît très rarement au lever ou au coucher du soleil. Comment cela se passe-t-il? La réfraction du Soleil par l'atmosphère crée un spectre vertical. Au fur et à mesure que le soleil descend sous l'horizon, les couleurs spectrales disparaissent une à une à commencer par le rouge, l'orangé, puis le jaune. Quand ces 3 couleurs sont disparues, quelques fois, à peine le temps d'un éclair, la seule couleur qui reste visible est le vert. 3, record 3, French, - rayon%20vert

At sea, air defense also uses large radars on ships, but more use is made of airborne radar and control systems. The weight and size of long-range radars restricts their installation to the larger ships; airborne radar over the ocean does not have severe land clutter to contend with, making it simpler than overland systems; the horizon limits are at a greater range; and the aircraft can patrol a large area. 2, record 4, English, - land%20clutter
