I have downloaded some data from http://asterweb.jpl.nasa.gov/gdem.asp

I would like to relate the elevations to some coastal data which is estimated to a specific ordnance dataum.

Can anyone tell me what the datum (i.e. 0) refers to in ASTER data?

Here's a one-line answer for you: in this Aster User Guide on page 55 the Datum for all ASTER data processed at GDS is WGS84.

Another one liner: this post has plenty of datum discussion.
