srtm - How to use SRTM30 Plus data with QGIS or other GIS tool?

I am trying to access the new Bathymetry data published here: http://topex.ucsd.edu/WWW_html/srtm30_plus.html

Is there a way QGIS or similar tool can read these files. Nothing seems to be working, but I am very new to using GIS tools and their rainbow of formats. Any examples or ideas would be appreciated.

Thanks Eric

Answer

These are what, files with a 'srtm' extension? Landserf (free) can load and convert these to something that QGIS can recognise (asc for example). Nick.
