Here are examples of the dynamic ocean topography maps the T/P satelliteprovides us every 10 days.
At top is the first monthly data set taken after the launch of the T/P satellite. At bottom is more recent data.
Ocean Dynamic Topography maps do not look significantly different from one another because general ocean circulation at these scales does not change much over 10's to 100's of years.
Areas of very low ocean dynamic topography (shown as magenta and purple)correspond roughly with where ocean water sinks near the Earth's poles.
