Compliance in underwater action? (10)

Ross

I believe the answer is:

submission

'compliance' is the definition.
(I know that compliance can be written as submission)

'underwater action?' is the wordplay.
'underwater' becomes 'sub' (as in submarine).
'action?' becomes 'mission' (mission is a kind of action).
'sub'+'mission'='SUBMISSION'

'in' is the link.

(Other definitions for submission that I've seen before include "Surrender - written contribution to enquiry etc" , "Compliance" , "Giving up" , "presentation" , "Proposal" .)

I've seen this clue in The Guardian.
