It's from over the pond or marina with ace waves (9)
I believe the answer is:
americana
'it's from over the pond' is the definition.
(Americana means things from the USA)
'marina with ace waves' is the wordplay.
'with' says to put letters next to each other.
'waves' indicates an anagram.
'marina'+'ace'='marinaace'
'marinaace' with letters rearranged gives 'AMERICANA'.
'or' is the link.
(Other definitions for americana that I've seen before include "Things associated with the US" , "Wild West material?" , "Things such as six down answers in this puzzle" , "Artefacts distinctive of the US" , "continental collection" .)
