As members of AAPG, we subscribe to a "Code of Ethics" that is supposed to guide our conduct as professional geologists. Where did this Code come from, and how does ethical behavior as promoted by AAPG fit into our careers and professional development? In this presentation, Dr. Ewing describes and analyzes the Code of Ethics, and relates it to our training as geoscientists, our professional growth, and long-term career plans. This course fulfills the one-hour credit in Ethics required for Professional Registration in various states.
