Volunteers from ten island nations, American Samoa, Fiji, Cook Islands, Papua New Guinea, Republic of Marshall Islands, Samoa, Solomon Islands, Tonga and Vanuatu, and the Solomon Islands joined forces with close to 800,000 volunteers in 2015 to commemorate the event which collected over 18 million pounds of waste across the planet.
All waste collected is stored in the Ocean Trash Index, having been recorded by item and by the Ocean Conservancy each year culminating in a global snapshot of the marine debris found across the world.
