On April 30, 2012, AMNH Science Bulletins hosted a one-hour online educational seminar about this data visualization. The webinar featured Dr. Matthew Rodell, a hydrologist at NASA and a member of the GRACE (Gravity Recovery and Climate Experiment) satellite team. Rodell and the visualization producers briefed participants and answered questions about how GRACE's data reveal changes in global and local water resources and how climate change and human activities strain those resources. They also offered strategies for interpreting the visualization. Download a video of the webinar here by "right clicking" and "saving target as".
