The person who found them posted a photo on a closed Facebook page but did not pick them up. However, the Vancouver Police Department have been informed and most likely one of the ferry operators has noticed it by now.
I'm sorry that I can't offer any further details. If you recognize these items, your best bet is to contact VPD or Aquabus.
