Where to get free seafloor elevation data

Question

While I have found multiple sources for continental elevation layers, I have been unable to find sea-floor elevation layers.

Specifically, I'm looking for data for the sea-floor around southern South America.

Question for Stack exchange: open data?

vterrain has a list of available bathymetry datasets which is a good starting point.

The USGS has a large amount of freely available bathymetry datasets - also covering Argentina

Depending on your resolution requirements the 1-arc second ETOPO1 also contains seafloor elevation.
