New Years celebrations were a week prior. However, there is a river outlet to the ocean adjacent to this divesite, with drainage leading directly from unfiltered storm drains on-island, probably the source of most of this trash.

Cassette tap from the 1970s in relatively good shape.

Metal Cans - vending machines are located everywhere along the shore on Okinawa

Plastic Bottles - vending machines are located everywhere along the shore on Okinawa

Plastic Fragments


Consider adding "credit cards" under plastics and "gaskets" under rubber as categories. First time I tried "preview" my data was dumped/lost. Uploading photos is very problematic, at least in Internet Explorer.
