A little bit salty

This is a very interesting video of how salinity varies in the global ocean, as measured by the SMAP (Soil Moisture Active Passive) satellite.  Even though the main thing it is designed to measure from space is soil moisture (how wet the ground is), it can also measure sea surface salinity (SSS).

The main features of interest in this, at least to my untrained eye, are the seasonal outflows of the Amazon and Congo Rivers, and the cold upwelling off of Panama, that occasionally sends out a jet of really low salinity water.   There's also some seasonal changes around the Ganges River delta, and off the U.S. East Coast.

Watch it a few times; maybe you'll see something you think is interesting that I didn't notice. I recommend doing this full-screen.
