Does the Catholic Church allow ashes to be scattered?

Hi, my parents have always been strongly Catholic, and we'll be having their memorial in a Catholic church. The plan is to have their bodies cremated, but I don't particularly want to keep them in my living room. Now, while I was brought up Catholic, we never spoke about cremation rules. Does anyone here know whether my husband and I will be allowed to scatter their ashes into the ocean? Thank you in advance.
