Usually an on-site workshop for remote-sensing users, enthusiasts, and experts who are interested in learning more effective ways to perform hyperspectral surveys or developing new applications, this event was held virtually. This is a streamed session on a mission by remote-sensing researcher and Headwall customer Dr. Prof. Luis Barbero, Professor of Geochemistry and Petrology at the Universidad de Cádiz, about a study done on red algae in the arctic. A live Q&A follows.
