But some of that energy comes back at wavelengths that are micro-wavelengths. And the microwave lengths - the amount of energy that's emitted by the ocean - depends on the salinity. It is related to something we call the "brightness temperature". It all has to do with how much energy is emitted from the ocean back to the atmosphere, back out to space. And so if a satellite is sitting there, it's actually recording how much energy in that microwave segment is being emitted. And by the signal that it receives, it's able to "back out" (i.e., calculate) what the ocean salinity is. Student Outcomes After viewing this video, students should be able to: Explain how new technology can enhance the gathering and manipulation of oceanic data.
