This is what sea surface temperature looks like off the coast of the southeastern U.S. in the fall, as seen from space. The scalebar is in Celsius. Those +'s are a grid of U.S. Navy towers that used to be for flight training. We have sensors at the ones with squares. The red streamer is the Gulf Stream, which is a stream of warm water that comes from the Gulf of Mexico and goes in an enormous clockwise circle in the northern half of the Atlantic Ocean. While it's doing that, it moves a lot of fish around and keeps England warm.
Making this sort of picture is approximately half my job description (other half being that ton of cruise data that I've been banging together a SQL database for in the past several months). I also make them for chlorophyll levels, dissolved organic matter, light penetration, and a number of other more arcane things. It's fairly mindless work compared to learning how to code things, and the results are pretty.
