The Jason 2 satellite will keep sea-level data stream going for some years.

You can read the original article here: Satellite for tracking sea levels set for launch

Excerpt below:
"The French-US satellite Jason 2, slated for lift-off Friday from California, will provide precise monitoring of rising sea levels and currents and track the effects of climate change.

I Found this map of the southern California region showing where the sea level was a few million years ago. Of course there has also been movement of land both lifting and lateral movement since then, so the map is very much an approximation.

NOTE however, that almost all of what is now coastal California... up to and including the Grapevine summit, was underwater. The top of Camino Cielo was beachfront.

The map was done in the 1930s.
