"Create a realistic portrait of Marcia McNutt, a middle-aged American female geologist and scientific administrator, in a formal setting that reflects her profession. She should be depicted in her 60s, with a warm and authoritative expression. Incorporate subtle background elements that hint at her work in earth sciences, such as a globe, a geological map, or a faint image of a seismic graph. Dress her in attire suitable for a high-level professional in her field, such as a blazer and a blouse. Ensure the image conveys a sense of intelligence, leadership, and dedication to her work."
