Dead Horse Bay and Bottle Beach

There’s a beach in Brooklyn that is always strewn with mostly bottles and dead horse bones. I’m not sure why. Why do bottles continue to wash up on only this shore? Where do they come from? My friend Anthony found a plate marked “Made in Occupied Japan” which means it’s from 1947-1952. What is it about the seas, currents, tides and underwater geography that brought it here somewhere around 60 years later? Many of the bottles look the same, that makes me think they’re all coming from the same bottling manufacturer or bottling plant.
