Researchers often release weather balloons at a variety of points during a storm to record any changes that might be occurring. Once it's released, the helium-filled balloon rises steadily and the instruments transmit data to the scientists’ computers.  2, record 1, English, - release

Le ballon-sonde est lâché au niveau du sol et s'élève dans l'atmosphère grâce au gaz léger qu'il contient (hélium ou hydrogène). Il est équipé d'une radiosonde, un ensemble d'instruments qui enregistrent la température, l'humidité et la pression de l'air à différentes hauteurs.  2, record 1, French, - l%C3%A2cher

Although they are sometimes confused, skidding is not synonymous with forwarding or yarding. Forwarding differs in that the logs do not come into contact with the ground and yarding differs in that the logs are carried on a cable or by a helium-filled balloon.  4, record 2, English, - skidding

Le débusquage est la première étape du débardage. Il consiste à acheminer les bois du site d'abattage jusqu'à un emplacement de regroupement où ils sont débardés par d'autres moyens de transport.  2, record 2, French, - d%C3%A9busquage

On différencie le débusquage du débardage en ce que le premier se caractérise par le transport en forêt du bois à partir du point d'abattage à un autre site de regroupement en forêt, tandis que le second décrit tout transport des bois de la forêt à un lieu temporaire ou définitif (usine, quai d'embarquement, etc.).  2, record 2, French, - d%C3%A9busquage

Agencies working for NASA use this term for a lighter-than-air aircraft designed to explore the planets. An aerobot is a helium-filled balloon fitted with heaters that are powered by solar cells. During the day, solar energy will heat the helium and give it extra buoyancy; at night, the balloon will drop to lower altitudes or even touch the ground. A limitation of the design is that its movements cannot be fully controlled, though it may have some ability to dictate its altitude, perhaps through dropping ballast, releasing gas or managing its temperature. A big advantage of this design is that it doesn’t need fuel, which is expensive to transport and which runs out all too soon. Unlike satellites, aerobots fly in the atmosphere, so allowing experiments to be carried out on its chemistry. They can also view and record the ground from much lower altitudes than is possible with satellites. NASA plans to send a device of this sort to Mars in 2003, and possibly later to Titan, Venus and Jupiter.  2, record 3, English, - aerobot

La mission prévoit d'envoyer un aérobot sur Mars pour étudier la présence d'eau et de vie. Cette déclaration de mission a deux objectifs distincts : l'un technologique : démontrer la réussite du déploiement d'un ballon solaire sur Mars, l'autre scientifique : faire fonctionner la charge utile qui recherchera de l'eau et de la vie sur la planète rouge.  4, record 3, French, - a%C3%A9robot
