In 1998, the neutron spectrometer located on the Lunar Prospector spacecraft, indicated that high concentrations of hydrogen are present in the first meter of depth in the regolith near the polar regions.
The current standard for large-volume (thousands of cubic meters) zooplankton sampling in the deep sea is the MOCNESS, a system of multiple opening closing nets, typically lowered to within 50 m of the seabed and towed obliquely to the surface to obtain low-spatial-resolution samples that integrate across 10 s of meters of water depth.
A spade to dig a hole of 1 meter (3.3 ft) x 1 meter (3.3 ft) x 1.5 meter (4.9 ft) of depth.
We suggest that martian thermokarst features are consistent with formation by sublimation, without melting, and that significant thicknesses of very clean excess ice (up to many tens of meters, the depth of some scalloped depressions) are locally present in the martian mid-latitudes.
Then, inside a big hole of more than 1.5 meter (4.9 ft) of depth lay the red hot stones.
The pattern of helium concentrations in the samples suggests that substantial parts of the western portion of the Grand Canyon were already carved to within a few hundred meters of their current depth by about 70 million years ago and that erosion hasn't increased dramatically in recent eras, the researchers report.
However, the 2016 Kumamoto earthquake also caused many smaller landslides with widths of less than a few tens of meters and depths of less than a few meters around the central cones of Aso volcano (Miyabuchi 2016).
Subsurface temperatures, from the ground surface to thousands of meters depth, have been measured in many parts of the world for commercial purposes such as exploitation of geothermal energy and for non-commercial purposes such as ecological research.
Any of these two scenarios, which would explain the glacial style and mobility of the VM landslides, also conform to the possible occurrence of Amazonian glaciations at mid-latitudes (e.g., Laskar et al. 2004; Madeleine et al. 2009) and the potential presence of ice at equatorial latitudes within some hundreds of meters depth.
However, it is difficult to transmit the data measured from down-hole environments with thousands of meters depth, high temperature, and high pressure.
