What is a Glider? – Follow the Glider https://followtheglider.socib.es/en/ Through Ocean Fri, 05 Jul 2013 08:17:03 +0200 en-US hourly 1 https://wordpress.org/?v=5.3 WHAT IS A GLIDER? https://followtheglider.socib.es/en/student/what-is-a-glider/ Mon, 27 May 2013 07:19:15 +0000 http://followtheglider.socib.es/?post_type=student&p=122 An underwater glider is a small submarine that’s autonomous–which means there’s nobody inside it, one reason being that nobody could possibly fit in there: it’s only about 2 meters long and weights around 50 kilos.

Underwater gliders are used to observe the seas and the oceans. Scientists place them in the water and the gliders collect interesting data about the temperature, the amount of salt and oxygen in the water, and so forth. They do so by using sensors that measure that information and much more (depth, etc.)

  • Gliders use their “wings” to glide along in the sea. They’re like airplanes, only in the water!
  • They use very little energy because they glide; they don’t have any motors or propellors.
  • They can dive as deep as 1000 meters.
  • They can go as fast as 10-20 centimeters per second in vertical motion, but if the currents help them along, they can go up to 1 kilometer an hour.
  • They can send data to the lab through their antennas, and receive data, too.

One of them is organizing an expedition with several scientists, hopping on a boat, and sailing off for a few days, weeks, or even months to take all kinds of measurements. What are the advantages and disadvantages of using underwater gliders instead of other systems like boats?
