Citizen science on a mega scale provided an unprecedented number of rainwater samples from Super Storm Sandy in October of 2012. Using Twitter, Facebook, science community e-mail lists, blogs, and crowdsourcing sites, researchers from the University of Utah invited volunteers to collect and submit rainwater as the storm passed. More than 125 volunteers submitted a total of 685 samples from places ranging from Indiana, North Carolina, and New Brunswick, Canada. The scientists say the data has revealed the storm's chemical signature with a new level of detail.
