Mars Electromagnetic Sounding Experiment (MARSES): Comparative and calibration studies on the example spatial and temporal variations subsurface geoelectrical sections of the saltwater interface on Sicily (Donnalucata Beach) and Shelter Island.

The MARSES is the sounding instrument program on the base new portable geophysical instrumentation developed of searching for water, water-ice or permafrost layers existing in some depth under the visible surface of Mars. The first task is to measure the soil properties of the subsurface of Mars, which include porosity, electrical resistance of the liquid phase, thermal conductivity, temperature dependence and so on. A main task of the MARSES experiment is to examine changes in subsurface properties of local areas regolith on the martian subsurface, and to relate them to optical images and other remote sensing data in order to understand the nature of different terrain forms and structure of cryolitozone of Mars. On the basis of results of several expedition programs in the earth’s conditions the optimum configuration of devices and techniques of measurement which allows to receive spatial geoelectrical structure subsurface horizons near martian landers or rover study area in the future martian missions is revealed. During cooperation within the frames of space research missions devoted to Mars exploration, which soil slice conditions are close to Earth's arid and semiarid lands, was developed compact, light and reliable instrument for subsurface sounding and mapping for Earth's applications, an
