]]> HOW DO WE READ THE DATA WE RECEIVE FROM A GLIDER? https://followtheglider.socib.es/en/student/how-do-we-read-the-data-we-receive-from-a-glider/ Mon, 27 May 2013 11:02:00 +0000 http://followtheglider.socib.es/?post_type=student&p=162 We use the data we receive from a glider to put together charts. They seem hard to read, but it’s actually easier than you think.

This is a chart showing the sea’s temperature: each column shows the glider’s course over several kilometers. Some columns are deeper than others. That’s because the glider doesn’t always reach the same depth. You know why? Because the sea floor isn’t flat. Sometimes there are mountains, and the glider can’t go any deeper: it would crash against the bottom.

This is a salinity chart, showing how much salt is in the water. The water with more salt is shown in red and the less salty water is blue.
