elevation correction

elevation correction
1. The correction applied to a measurement of gravitational attraction to allow for the distance to the station from the theoretical reference surface and for the attraction of the rocks in this zone. It is a combination of the free-air and Bouguer corrections.

2. (static correction) The correction which is made to seismic travel-time data to compensate for irregular topography and to reduce the data to a common datum. Land ‘statics’ are extremely important in seismic surveying on land. As part of a ‘statics’ survey, refraction shooting is undertaken to determine the depth and velocity of the weathered zone (the low velocity layer, or LVL). This is done in order to design more effective seismic source parameters (e.g. ideally, the shot depth should be below the weathered layer) thereby optimizing the seismic reflection surveys which are undertaken after an LVL survey. In marine surveys, marine ‘statics govern the source—hydrophone geometry and provide a correction for the finite offset between the source arrays and the hydrophone streamer.

Learn more about citation styles

Citation styles gives you the ability to cite reference entries and articles according to common styles from the Modern Language Association (MLA), The Chicago Manual of Style, and the American Psychological Association (APA).

Within the “Cite this article” tool, pick a style to see how all available information looks when formatted according to that style. Then, copy and paste the text into your bibliography or works cited list.

Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, cannot guarantee each citation it generates. Therefore, it’s best to use citations as a starting point before checking the style against your school or publication’s requirements and the most-recent information available at these sites:

  • Most online reference entries and articles do not have page numbers. Therefore, that information is unavailable for most content. However, the date of retrieval is often important. Refer to each style’s convention regarding the best way to format page numbers and retrieval dates.
  • In addition to the MLA, Chicago, and APA styles, your school, university, publication, or institution may have its own requirements for citations. Therefore, be sure to refer to those guidelines when editing your bibliography or works cited list.
