H. O'Brien, in Mineral Deposits of Finland, 2015. Pipe 17. Kylmälahti. Geophysical surveys included magnetic and electromagnetic profiles. 21 till samples were taken to investigate the heavy mineral content of the area but only picking results are available. 20 diamond drill holes were drilled to estimate the size and shape of the body. Kimberlitic material occurred in 12 drill holes.

2016 Chapter 3 Geotechnical Investigation and Sampling

1 Introduction. Geophysical measurements can reveal the interior properties of icy ocean worlds. Such measurements can point to the presence and temporal variability of fluids and gases, thus identifying potential habitable niches for life (Vance et al., 2017).The thickness and geodynamics of different ice phases, and the depth of the ocean, determine the conditions under which life might exist.
