Geophysics is the subsurface site characterization of the geology, geological structure, groundwater, contamination, and human artifacts beneath the Earth's surface, based on the lateral and vertical mapping of physical property variations that are remotely sensed using non-invasive technologies. Many of these technologies are traditionally used for the exploration of economic materials such as groundwater, metals, and hydrocarbons. Magnetometers and gradiometers are used to acquire high-resolution data for a non-invasive archaeological investigation. In looking at the previous topic, it may not be immediately apparent that there are distinct components of environmental and engineering sub-disciplines within each "problem" or application area. Applications, such as Groundwater and especially contaminant plume mapping, UXO, and Archeology are closely aligned with Environmental Geophysics. Citations are important for a journal to get an impact factor. Impact factor is a measure reflecting the average number of citations to recent articles published in the journal. The impact of the journal is influenced by impact factor, the journals with high impact factor are considered more important than those with lower ones. To increase the visibility and ease of use of open access scientific and scholarly journals PrimeOA Publications top online publishing journals are indexed in different indexing and archiving services.
