Yeah, when we (fam) were doing the burial at sea thing for my Dad (cos ex-sailor), we were told to put the container under water, open the lid and swish gently until the container was empty. Then dispose of the container thoughtfully. Same for my Mum at the same beach. We were SPECIFICALLY warned not to attempt to open the container in the air and then dump cos of the air cushion effects just above the water - the ones that keep albatrosses flying for months at a time. And not to just heave the container into the ocean unopened because it would eventually be washed ashore just like the one you found as there’s quite a lot of air in the standard container as well as the remains. My guess is someone wasn’t listening or didn’t read the instructions given by the crematorium.

I’m thinking someone dumped the box because it was cheapest or least effort
More than possible, probably you’re correct.
