Surface Water and Ocean Topography

Surface Water and Ocean Topography

Southern Ocean near-surface current speed from ECCO2

Satellites can do amazing things there days. I bet you haven't seen an image of ocean currents around Antarctica like the one above before. Simply ├╝ber cool. The SWOT mission will give us information about water tables on land AND sea surface height - in one go. :-)

Why do we care? Because we want to know where the water is, preferably all the time, so that we know when to water our fields, know if there will be shortage of fresh water and if sea level will rise.
