  • Application of Marine Magnetic and Gravity Data in Mapping ...

    Marine magnetic and gravity data, acquired in 2010 during seismic data acquisition over part of the Rovuma Basin, Mozambique, was used to map basement and two intra-sedimentary horizons. Depth estimates to these three horizons were derived from the interpretation of energy density spectra of magnetic and gravity data.

  • Marine Data Acquisition – EDCON-PRJ, inc.

    The majority of marine gravity and/or magnetic data are collected in conjunction with other survey methods. Most marine gravity and magnetic survey work takes place as an addition to seismic surveys, but marine gravity and/or magnetic data are also collected on EM surveys, ROV projects, multi-beam bathymetric surveys, and other hydrographic projects.

  • Gravity and magmetic method - SlideShare

    Magnetic methods, as employed in marine applications, differ little in theory from surface magnetic surveys. The instrument measures the earth's total magnetic field at each measurement location. However, practical applications of field techniques, field equipment, and geographic control can vary greatly between surface and marine surveys.
