Part on edge as deep ice is melting (9)

Ross

I believe the answer is:

sidepiece

'part on edge' is the definition.

'deep ice is melting' is the wordplay.
'melting' indicates anagramming the letters.
'deep'+'ice'+'is'='deepiceis'
'deepiceis' with letters rearranged gives 'SIDEPIECE'.

'as' is the link.
