July 21 to July 29 Komodo to Bali
July 31 to August 8 Bali to Komodo

Our 18th Expedition will travel through Indonesia’s Coral Triangle from Bali to Komodo to sample microplastics and explore solutions to the problem of plastic pollution. Groups will be lead by 5 Gyres Co-Founder and Research Director Marcus Eriksen and 5 Gyres Science Programs Director Carolynn Box. 

Through our Asia Pacific Action Against Plastic Pollution program, 5 Gyres is collaborating with NGOs in Southeast Asia to highlight and scale zero-waste efforts in the region. To better understand the long-term impacts of these initiatives, representatives from participating NGO groups will join the Expedition to train on citizen science protocols. They will also be loaned equipment through our TrawlShare program in order to continue monitoring plastic pollution in the region.

Data collected on this Expedition will be incorporated into our global dataset of microplastics, used in the update of 5 Gyres’ Global Estimate of Marine Plastic Pollution study. In keeping with our “science to solutions” model, a better understanding of the global scope and trends related to ocean plastic pollution will help us monitor the efficacy of upstream solutions over time.

This Expedition is produced in partnership with the Oceanic Society, whose mission is to conserve marine wildlife and habitats by deepening the connections between people and nature. Along the route, the voyage will overnight at a variety of small islands including Lombok, Satonda, Moya and Sangeang, as well as Komodo National Park, a collection of rugged volcanic islands located in Indonesia's Lesser Sunda Islands. In addition to collecting valuable near-shore data, guests will explore lush tropical forests, visit world-renowned cultural sites, and snorkel through the cobalt blue waters and stunning coral reefs that provide unique marine microhabitats to invertebrates and reef fish. 

Thanks to our sponsors!

5 Gyres joined the Hello Ocean Expedition to research environmental threats to the Belize Barrier Reef, the second-largest barrier reef in the world. The crew included scientists, artists and filmmakers, who assisted in marine mammal and plastic pollution research. For the first time, 5 Gyres was able to collect microplastic samples alongside scientists researching toxins, genetics, and animal behavior in dolphins and manatees. We are excited to better connect the issue of plastic pollution to marine mammal health! Data will contribute to our Global Estimate of Plastic Pollution, which was the first to assess the quantities of surface plastic pollution in the ocean, finding 5.25 trillion particles weighing in at 270,000 tons of “plastic smog” worldwide.


Our 17th Expedition gathered a group of 22 citizen scientists for two weeks on the Arctic exploration vessel Akademik Sergey Vavilov. The expedition primarily focused on micro- and nanoplastic research. It was managed by ExploringCircle, which donates a percentage of proceeds to non-profit organizations like 5 Gyres, and was the first  to share real-time data and photo updates with our community.


As documented in the "Smog of the Sea" film directed by Ian Cheney, our 2015 SEA Change Expedition traveled over 3000 nautical throughout the North Atlantic Gyre with a crew of 64 citizen scientists. Along with the Schooner Mystic crew of 14 sailors, the voyage also transported representatives from other nonprofit organizations and research facilities, as well as notable watermen and women, such as musician and activist Jack Johnson and ocean conservation activist Celine Cousteau.


5 Gyres' Expedition from Bermuda to Iceland was designed with the intention to better understand the distribution of plastic pollution in the North Atlantic Subpolar Gyre. The 14-person crew collected 41 samples to determine microplastic concentrations in the region and carried out  40 visual observations to track the macroplastic pollution in the area. Data contributed to 5 Gyres' first Global Estimate of Plastic Pollution.
