The Global Clarity Water Project invites participants to help build a growing dataset of water images from around the world using simple smartphone photos. Participants can submit photos of tap water, bottled water, rivers, lakes, oceans, rainwater, or other water sources along with basic location information. The project explores how image-based observations may help study water clarity, environmental patterns, and differences across locations over time. No special equipment or scientific background is required. Anyone can participate once or multiple times.
