Swooping around Northern Ireland looking for water (8)

I believe the answer is:

divining

'looking for water' is the definition.

'swooping around northern ireland' is the wordplay.
'swooping' becomes 'diving'.
'around' means one lot of letters goes inside another.
'northern ireland' becomes 'ni'.
'diving' going around 'ni' is 'DIVINING'.
