Gravity and magnetic studies have been published in the GSA Bulletin during most of its history. As demonstrated in the pages of the Bulletin, these techniques have evolved from crude measurements of only regional significance into mature research tools useful at any scale. Gravity and magnetic data have contributed to our understanding of geologic problems and features around the world. The equipment, data processing, and interpretation techniques, and, in many cases, the actual data needed to employ gravity and magnetic data in integrated studies are readily available. Thus, it is appropriate to anticipate that these techniques will find even greater use in the future. It is disappointing, however, to note that papers in the Bulletin involving gravity and magnetic data have decreased in number in recent years.
