Airborne Gravity 2010 The Quest A few final thoughts are provided on the gravity quest. A quest is an act of seeking. It could be called a search, pursuit, investigation, mission, hunt, or expedition. In any event, it involves the act of looking ahead. So, we should ask questions that will be directive to help us reach our destination. What will exploration look like in 2015? In 2025? In 2050? If I am pressed to predict or forecast how the future will look, here are some of the key elements I would include (DiFrancesco, 2009b): 1. Airborne surveys will be flown at faster speeds and coverage rates and in higher dynamic conditions. 2. Scalar gravity and gradients will be measured with greater precision. 3. Survey costs for airborne gravity will be significantly lower. 4. Integrated scalar gravity plus second and third order tensor gradient data will be available in a single service offering. 5. Gravity (scalar and tensor), along with both magnetics and EM, will be configured on the same survey aircraft so that an economy of scale is realized. 6. A series of significant exploration successes will be attributed to gravity and gradiometry. 7. The market will really understand what gravity and gradiometry can do for them. Conclusion It is readily apparent that airborne gravity is becoming a mainstay of the exploration industry. Technical and operational advances in the past few years have enhanced the capability, and there is a foundational acceptance for the benefits of these techniques. A growing understanding of gravity benefits and utility is being communicated to the market in the form of workshops, technical publications, and first-hand experience. It is also clear that the way things have been done in the past will not support the needs for the next generation of explorationists. New technology, new approaches, and out-of-the-box thinking will be necessary to keep airborne gravity relevant and lead the charge to further exploration success. It is also important to emphasize that the outcome of this workshop must be more than just the sharing of information and status, but the provision of vision and direction for the future.
