The “Sea to Source: Ganges” river expedition, in partnership with the Wildlife Institute of India (WII), the University of Dhaka and WildTeam is an unprecedented and unique opportunity to get a holistic view of the plastic pollution issue in a watershed and ultimately, how to solve it.
Heather J. Koldewey is a 2018 National Geographic Fellow and scientific co-lead of the National Geographic Society’s effort to better understand the impact and scope of plastic pollution in our waterways through scientific research and exploration. Koldewey joined the Zoological Society of London (ZSL) in 1995 as a postdoctoral research scientist before becoming curator of the ZSL London Zoo Aquarium and then head of marine and freshwater conservation. She currently serves as ZSL’s senior technical advisor.
Koldewey finds solutions through interdisciplinary research and conservation action at the interface between communities and environment. In 1996, she co-founded Project Seahorse, a group recognized as the world’s leading authority on seahorses and an early pioneer of community-based marine conservation. More recently, Koldewey developed Net-Works, an award-winning project that has implemented a novel, community-based supply chain for discarded fishing nets that are recycled into nylon yarn used for carpet tiles and fashion, addressing issues of marine debris and poverty alleviation in coastal communities in developing countries. She also leads the Bertarelli Programme in Marine Science, an interdisciplinary research and conservation programme for large marine reserves involving 66 researchers from 18 institutions and seven countries.
Koldewey uses collaborative, optimistic and values-based approaches to communicate and engage people in marine conservation, including One Less, a campaign to build a more ocean-friendly society through working to make London the first capital city to stop using single-use plastic water bottles.
As scientific co-lead of National Geographic’s plastic pollution initiative , Koldewey will help lead an international, all-female, interdisciplinary team in developing a scientific plan to combat plastic pollution, starting with an initial expedition this spring to study the type and flow of plastic in the Ganges River. Through the expedition, the team will work with National Geographic and international partners to provide science-based, actionable information to help local and national governments, non-governmental organizations, businesses and the public more effectively invest in and implement innovative solutions to the plastic waste crisis.
An honorary professor at the University of Exeter, Koldewey graduated with a Bachelor of Science in biological sciences (marine and fish biology) from the University of Plymouth and a Ph.D. from Swansea University.Back

Marine biologist and sea turtle researcher Emily Duncan is a National Geographic Early Career Grantee and postdoctoral researcher. After completing her B.Sc. in ecology and conservation at the University of Exeter, she continued on to her Ph.D. entitled “Investigating impacts of plastics on marine turtles,” which has been at the forefront of method development and assessment of this threat to marine turtles. Broad research areas she covered include diet-related selection of ingested macroplastics and links to feeding ecology, novel method development to isolate and identify microplastic ingestion, the distribution of plastic burdens on critical nesting beaches, and oceanographic modeling of source locations and global assessment of marine turtle entanglement. She has worked on collaborative projects with organizations and institutions that include Plymouth Marine Laboratory (England), Duke Marine Laboratory (U.S.), Queensland Government (Australia) and Marine Turtle Conservation Project (Cyprus).
Living in Falmouth, Cornwall, England, Duncan has become a keen sailor and was recently invited to be the head of science on eXXpedition’s North Pacific voyage (first leg), an all-female crew sailing through the heart of the North Pacific Gyre (Hawaii to Vancouver), collecting samples for marine plastic research.
Duncan’s latest turtle research will focus on working with a unique set of post-hatching samples that have been stranded on the Queensland, Australia, coastline. These are potentially some of the most vulnerable yet understudied life stages of marine turtles, largely due to the presence of plastic pollution in the marine environment, the size of the turtles and their location. Analysis will be undertaken to discover the extent of macroplastic presence and the possibility of microplastic ingestion, and to investigate the link between plastic ingestion and persistent organic pollutant burden.Back
Sarah Nelms is a marine conservation scientist from south-west England, an area well-known for its beautiful and rugged coastline that inspired her love of the sea and the desire to protect it from an early age. Nelms holds a Bachelor of Science in environmental biology from the University of Plymouth and a Master of Science in conservation and biodiversity from the University of Exeter. She recently completed her Ph.D. at the University of Exeter and Plymouth Marine Laboratory, where her work focused on marine litter, specifically plastic pollution in coastal environments and microplastic (plastic less than 5 mm in size) ingestion in marine mammals such as whales, dolphins and seals. She has also conducted research on the broader impacts of plastic pollution — ingestion and entanglement — on marine mammals, turtles and seabirds.
Nelms is a strong advocate for scientific outreach and has written a children’s book that tells the story of a turtle that accidentally eats a plastic bag it mistakes for a jellyfish. The book has been translated into seven languages and is used in homes and schools worldwide to spread awareness about the impacts of plastic pollution on marine animals and to inspire the next generation of marine conservationists.Back
Surshti Patel is a technical specialist in the marine and freshwater conservation team at the Zoological Society of London (ZSL). Since joining ZSL in 2013, Patel has worked on a number of projects in Europe, Africa and South-East Asia, conducting interdisciplinary research and conservation, and leading the development and implementation of monitoring and evaluation systems.
Patel has more than five years’ experience developing pro-poor, equitable and scalable solutions for community-based marine and freshwater conservation, integrating plastic waste management, protected area establishment, sustainable livelihood development and access to financial services. Since 2014, she has worked on Net-Works, an award-winning solution implementing community-based supply chains that deliver “less plastic and more fish,” integrating business and non-governmental organizations to address global marine issues. To date, Net-Works has prevented nearly 225,000 kg of plastic in the form of discarded fishing nets from entering our ocean, recycling the nets into carpet tile. Patel has also worked on the Angel Shark Project in Wales, which aims to safeguard one of the world’s rarest sharks through fisher participation, heritage and citizen science. Previously, her research focused on payments for ecosystem services) in South America, investigating forest fragmentation and carbon storage in tropical Amazonian forests.
As the marine plastics social researcher for the National Geographic Society’s Source to Sea expedition, Patel will work with an international and interdisciplinary team investigating multidimensional poverty and socioeconomic drivers behind the plastic waste crisis. This research will contribute novel research towards understanding the relationship in the poverty and plastics dialogue and will help develop science-based solutions for waste management in poor rural communities.
Patel graduated with a Bachelor of Science in geography at the University of Leicester, and a Master of Science in environmental sciences from Kings College London.Back
Marine scientist Imogen Napper is a National Geographic Sky Ocean Rescue Scholar. She developed her love of the ocean from a young age as she learned to sail and surf in her seaside hometown of Bristol, England. Once she began noticing the effects of plastic contamination on beaches, her passion to be part of the solution grew. Napper received a B.Sc. in biomedical science and an M.Sc. in biotechnology. She is now finishing her Ph.D. in marine science at the University of Plymouth, focusing on the sources of plastic in marine environments. Her work recently helped influence the ban of microbeads in cosmetics internationally. Her research was also the first to analyze different fabric types (such as polyester) to determine how many plastic fibers come off during clothes washing. She found that up to 700,000 fibers could potentially come off from a single wash of acrylic clothing. Napper will be working to identify the most effective technology for capturing the tiny microplastic fibers that are released when clothes are washed. “The results will be used to help educate the public that behavioral changes in their lifestyle can be a major solution to the plastic problem,” she says.Back
