We are a team of scientists and engineers seeking to support and learn from the cleaning of the Gowanus Canal in Brooklyn, NY. We designed and built an Aquatic Robotic Vehicle (ARV) which is placed in the canal, collects sensor data (such as water quality) and takes pictures both below and above the water level. This is where YOU, our citizen scientists, come into play. We need help tagging all of the images that our ARV collects, whether it is a fish, a rock, or an unidentified object. The aggregate data will help us study the conditions at the canal in different places and over time. Helping is simple: just login or create an account here and press Participate to start tagging.
