Well, we figured why not continue doing Disney-related theme science since we've already started with two so far this week! In WALL-E, we all know that his job was to clean the surface of our planet from an over abundance of trash. At USGS, we use robots like JASON (in partnership with other organizations) to study how upstream land-use changes (e.g., runoff from plowing, drainage, irrigation, fertilizer, etc) have an affect downstream on habitats like deep-sea coral systems.
