Day-of Poster Session Information
- Poster Session Hours:Â Tuesday, March 13th, 5:15 pm â 7:30 pm
- Poster Session Location:Â Garden Pavilion
- Perusing the Posters:Â Each poster has been assigned a number and will be grouped with other posters within the same track with a similar theme. Poster numbers were displayed prominently on the posters. A list of posters (with poster numbers) was published in the conference program book and assisted with conference attendees in finding a particular poster.
Poster Session Guidelines
Poster dimensions cannot exceed 45 inches x 45 inches (114.3 cm by 114.3 cm). Each poster presenter will be sharing a 4âH x ~ 8âW poster board with one other presenter (see diagram). PLEASE NOTE: Your poster and poster materials cannot exceed 45 inches in width. Pushpins will be provided onsite to hang posters.
The poster presentation should cover the material as described in the abstract. The poster title should be the same as the title submitted with the abstract and displayed prominently at the top of the poster to allow viewers to easily identify your poster. Presenters were required to be present at their poster for the duration of the poster session.

Poster Suggestions and Tips
- Please provide authorâs names and contact information on the poster. This will allow people to follow up if they are interested in more information.
- Keep content simple and provide a clear message. Please use an appropriate size font, so that it is legible 3 – 5 feet (~1 – 1.5 meters) from the poster board. Figures, tables, and diagrams should also be legible from this distance.
- Consider putting a picture of yourself on the poster so people can identify you at the conference.
- Consider your audience. Keep in mind the diverse mix of conference attendees, including people representing a variety of vocations (scientists, educators, industry, policy, students, etc.) and attendees coming from many countries.
- To minimize waste, please consider business cards for follow up correspondence in lieu of printed poster handouts

Keynote
Afroz Shah, Environmental Organizer | Mumbai, India
Afroz Shah is a young Indian lawyer from Mumbai who has become synonymous with the worldĘźs largest beach clean-up project. In October 2015, Shah and his neighbor Harbansh Mathur, an 84-year-old who has since passed away, were frustrated with the piles of decomposing waste that had washed up and completely overwhelmed the cityĘźs Versova beach. Determined to do something about it, the pair started cleaning up the beach themselves, one piece of rubbish at a time. Every weekend since, Shah has inspired volunteers to join him â from slum-dwellers to Bollywood stars, from schoolchildren to politicians. This impressive eďŹort inspired Indian Prime Minister Narendra Modi to make beach cleanups part of the Clean India surge. As a result, beach clean ups are being organized on 13 other beaches around the country, and similar eďŹorts are being carried out around the world.

6IMDC TECHNICAL SESSIONS
Technical Topics
The Sixth International Marine Debris Conference (6IMDC) brought together international marine debris researchers, natural resource managers, policy makers, industry representatives, and the nongovernmental community. The impetus for this international marine debris conference was the pressing need to address and reduce the impacts of marine debris to vital natural resources, human health and safety, and the economy.
Objectives of this international conference included sharing lessons learned and best practices to reduce and prevent marine debris and its impacts; promoting international co-learning; exchanging innovative ideas such as market incentives and communication strategies; and sharing the latest research initiatives, methods, and results. This conference was structured to be action, solution, and change-oriented.

What is Marine Debris?
Our oceans are filled with items that do not belong there. Huge amounts of consumer plastics, metals, rubber, paper, textiles, derelict fishing gear, vessels, and other lost or discarded items enter the marine environment every day, making marine debris one of the most widespread pollution problems facing the world’s ocean and waterways.
Marine debris or marine litter is defined as any persistent, manufactured or processed solid material discarded, disposed of, or abandoned in the marine and coastal environment. It is a global problem, and it is an everyday problem. There is no part of the world left untouched by debris and its impacts. Marine debris is a threat to our environment, navigation safety, the economy, and human health. Most of all, marine debris is preventable. For more information on specific projects, visit the Marine Litter Networkâs project map to learn more about initiatives on marine debris around the world
Honolulu Strategy
The Honolulu Strategy is a framework for a comprehensive and global effort to reduce the ecological, human health, and economic impacts of marine debris. You can find more information here. It is intended for use as a planning tool, common frame of reference for collaboration, and a monitoring tool on multiple levelsâglobal, regional, national, and localâinvolving the full spectrum of civil society, government and intergovernmental organizations, and the private sector.


IMDC Historical BackgroundÂ
In March 2011, the Fifth International Marine Debris Conference (5IMDC) was held in Honolulu, Hawaii in cooperation with NOAA, the United Nations Environment Programme, and other agencies and organizations. The conference brought over 450 participants from the marine debris community together to develop and create a document known as the Honolulu Strategy. All told there were 45 sessions with 213 oral presentations, 5 panels, and 65 poster presentations on issues ranging from the role of government, industry and consumer choice in preventing marine debris to community led coastal cleanups. Several sessions focused on the latest research in the field of marine debris and illustrated that the problem is pervasive, impacting all ocean areas.
Collectively, these sessions and the numerous plenary speakers highlighted the complexity of the marine debris challenge facing the international community. Many speakers highlighted the challenges surrounding the presence of plastics in the marine environment. Importantly, the conference drew attention to the detrimental and cascading impacts of debris to marine ecosystems and their biodiversity. 5IMDC proceedings are available here.

@415Plumberâs #OB_Plastic Obsession Jeff den Breeder (USA) | 7 min
Grabbing a few rays at the beach could get you stuck by a used needle, though it rarely leads to a lifelong environmental preoccupation. But thatâs what happened to Aaron, a plumber who now spends a couple of hours a day scouring San Franciscoâs Ocean Beach for plastic-dollsâ arms, key rings, animals and soldiers. He works alone, enjoying the meditative silence.
Ainât No Fish Tom Gasek & Miki Cash (USA) | 4 min
A short stop motion animated film featuring a bunch of hungry Arctic seals singing along to the music and lyrics of Sigman and Russell as performed by Hoagy Carmichael. Itâs an âeasy-goluckyâ song about fishing and why âSome Days There Just Ainât No Fishâ.

Marine Pollution Bulletin Virtual Special Issue
A Virtual Special Issue in Marine Pollution Bulletin, a peer-reviewed scientiďŹc journal, will feature highlights from the 6IMDC. This Special Issue will present data on marine debris ranging from nanoplastics to derelict ďŹshing gear and abandoned and derelict vessels, found in freshwater bodies, coastal zones, and the open ocean. We welcome original papers on topics including monitoring and citizen science, economics of marine debris, research on impacts to wildlife, the chemistry of marine debris, fate and transport, and implementing eďŹective policy, as well as the dialogue on innovative solutions for prevention, removal and education.
