The purpose of this toolkit is to provide detailed steps for implementing the methodologies that were carried out during the National Geographic “Sea to Source: Ganges” river expedition (hereafter referred to as the “Sea to Source Expedition”), which set out to better understand and document the characteristics, composition, and flow of plastics in the Ganges River Basin. The Ganges is known as the Ganga in India and Padma and Meghna in Bangladesh (hereafter referred to as the Ganges).

This toolkit is designed to provide researchers around the world a framework so they can apply the Sea to Source Expedition methods to address similar research questions in their own river systems and local contexts. The Sea to Source Expedition team was an interdisciplinary group of international scientists and engineers coled by National Geographic Fellows Jenna Jambeck and Heather Koldewey.
